As I write this we had our first snow fall last Friday. I can't believe Christmas is
less then a week away! I know most of you may not drive your cars as much in the
winter, but use the down time mainly for repairs and upgrades. My Wedge cars
have always been a creative outlet and therapy for me. While some enjoy playing a
musical instrument I prefer to wrench. Over the past 20 plus years I have worked
on some of the finest and fastest Wedges known. I recently, through the help of
Mike Perkins picked up a bone stock 40k mile TR8 coupe. This car was outside for
over 20 years. Mike stumbled on this in the DC area. We met the 2nd owner who
purchased this car back in the mid 80's.He was very happy that we came along
and saved it from the bone yard. This thing was a time capsule, we even found a
TR8 newsletter. I have been working on this for the past 4 weekends and started it
up on Saturday. The bad thing is that I made a choice to complete the startup of
the TR8 versus Christmas shopping. Stay tuned because we will do a write-up on
this for one of the upcoming newsletters. The TWOA
finished the year strong. We had great turnouts on all of
our events. The club received a special thank you gift
from the Triumph Sports Car Club San Diego for helping
with Triumphest 2010. I would like to personally thank all
club members for doing their part in making all of the
2010 events a success. The focus for 2011 will be to do more of a series of re-
gional events. For example, Maryland has a British car day on June 5th. There is
another event in Texas. The plan is to announce more of these events and depend-
ing on what part of the country you are from try to make it. The original club was
based on smaller car shows, sort of a meet and greet format. We will have most of
these events listed on the Website so stay tuned. Merry Christmas to all and have
a happy and safe holiday!! Tim Lanocha TWOA President

A Letter From the Prez
Thought I would send a quick note out to mention the 2011 Maryland British
Car Day on Sunday June 5th. It is held in Adamstown near Frederick MD . Check
it out at www.chesapeakechaptermgtclub.com/OBCD_main.htm
Some of you may remember years ago when the club first started we use to
attend this show when it was held in Bowie MD at Allens Pond. The show got too
big so they had to move it and it wound up in Frederick. I have been out of the
area for the last 15 years and recently moved back to MD. I have never attended
this show at its new location but hear it is an excellent show with 400 + cars in
attendance in good weather. We have been pushing The Roadster Factory show
for the past few years and since that seems to be cutting back next year figured
maybe this is a good time to push a new venue for a club organized event. Many
of us core members live in this area so I would like to resurrect “the good old
days” and plan something special around this show. Close by the show are a
couple of dragstrips and there is a strong SCCA autocross presence in that area.
We already have a volunteer to coordinate the Bill Sweeting cruise and dinner
night for Thursday or Saturday and I’m researching coordinating a night at the
drags on Friday and an autocross event if at all possible on Saturday. There are
lots of hotels in that area as well so we will look at getting a club discount at one
of them and have a host hotel. We are still working out the details but just wanted
to get the bug in everybody’s ear as early as possible to start planning now. We
would try to get other local British car clubs involved as well. Of course some of
us will still attend the TRF show but am told there are no drags or autocross there
this year. Mike de Andrade TR8CCA/TWOA Club Founder

Wedge Stopping Distances Revealed - Jim Tencate
Triumph Wedge Owners Association December 2010
Thanks to a G-Tech I got off eBay, I now have some real data from a G-TechPro on 60-0 mph braking for a stock TR8 and
Larry did the same for his TR7. So far, just a few runs to date. We're hoping to add to our "database"! Interested? I can
loan out my G-Tech.
Details:
* 1980 FI Triumph TR8 DHC
* Wheels/Tires: 14 inch Superlites, Michelin Pilot Exaltos 195-60R14, recently new
* 1/2 tank of gas, miscellaneous junk in the trunk, just me driving (about 160 lbs)
* Rear brakes, stock. Functioning.
* Front brakes, stock rotors, some semi-metallic pads I got from Ted S. years ago.
* Brake Fluid: Ate Super Blue Racing brake fluid ($13.99 a litre on Amazon)
* Stock springs all around (really)
* KYB front struts, MonroeMatic 1194 shocks rear (really)
* Extra packing piece "anti-dive" kit (Richard Hurdwell)
* Test details: 19 Sept 2010 ~21:00, flat stretch of moonlit road, only passed one coyote on the way to the test stretch, fog
lights on, high beams on, ~7000 ft altitude, 65 F outside temp
I'm SURE the STOCK, non-modified brake pressure reducing valve works, I stuck a brake pressure gauge on it and
watched it and measured it to be sure it was working (there's a fuzzy YouTube video I posted showing that if you search just
a bit). Brakes were thoroughly bled with SpeedBleeders. Out with ALL the stock yellow Valvoline brake fluid, in with the
BLUE, nothing fancy. Just a complete and thorough flush about a week before the test.
The GTech is mounted firmly (rubber bands) to an old 1976 TR7 center speaker grill (the grooved holes were handy) and
aligned with the lines on the grill to point straight ahead. See the photo below. I leveled it before starting. The test is sim-
ple. You put the GTech in acceleration mode, it says Go! and you accelerate up to and beyond 60 mph, it displays your 0-60
time and then you mash the brake and the thing measures how many feet it takes to go from 60-0 mph (it knows how fast
you're going) and displays the whole thing in a series of flashing numbers, first the 0-60 time in seconds, then the 60-0 mph
time in feet. Claim is that the braking distance is good to plus or minus 2 feet. Not sure I believe that yet. It DOES say to do
a series of tests and average and I'll bet it's that AVERAGE number which is good to within plus or minus 2 feet. We'll see as
I do more runs
I had tried this earlier with mixed success and finally got it down
to where I could make it work reliably. Took it out tonight and drove
out to the start point (this IS a deserted road this time of night),
pushed the button on the GTech, waited for Go! and took off. A lei-
surely 12 second later I hit 60 mph and then I mashed the brake.
I took a movie of the flashing display. The relevant braking dis-
play numbers are shown as three snapshots below.
For those of you that can't read it, it's 137 feet. ALL the tires were starting to squawk and I was trying VERY hard not to
let any of them lock up. Very solid brake feel, a little squirmy on straight line braking but generally a pretty good stop. I was
surprised and pleased as I was expecting something more along the lines of 150 ft or more. That's equivalent to the X1/9 of
the day, right? Anyone know what the "press" reported back then? Over 170 ft if I recall. This result seems massively bet-
ter than the first press reports, even better than the original TR7's 150 feet.
As Bob Lang or Jack McGahey will remind us, it's the wonder of modern tires people.
Larry got his G-Tech out and promptly recorded 130 ft with a 76 TR7 converted to a 5 speed. We're waiting on more re-
sults with different brake setups and wheels and tires. Woody has a 50-0 mph movie posted on his site and we still haven't
recorded times with one of Ted's modified brake valves either. Too much to do and the snow is flying. Wayne and Jack
both want to try, Jack with sticky auto-x tires. We'll see. Funny thing? I think I could actually do BETTER with a little prac-
tice!
G-TechPro mounted on the front speaker grill on the
"test" car, nearly reading zero (which is what it says
when you get it perfectly level). Jim's best TR8 braking distance, stock TR8

Wedge Door Lights NLA - Jim Tencate, Ivan Love & Mick Harper
Triumph Wedge Owners Association
December 2010
This is bad, really bad, especially if you're a Concours nut. You know those neat little adjustable courtesy door lights on
later model wedge cars? (1) Push them down and they light up only when the door opens, (2) push them up and they just
turn on and (3) in the neutral-middle position they just blend into the door. They're rather nice when they work, but lots of
times they don't. Either the bulb has burned out, the mechanism inside has failed, or the door switch has gotten corroded
up. The door panel needs to be removed to replace the bulb too, not a job you'll tackle lightly. Plus, after a recent pretty
exhaustive search, it seems they've essentially become as hard to find as a working TR7 Solex Fully Automatic Starting De-
vice. If you have two working ones, thank your lucky stars. If you break one, good luck trying to fix it, they usually break
rather badly as you'll see. Old plastic is brittle plastic. To find a new working one, you may have to prowl eBay for months.
Below is a photo of my door light collection. Only one of these is perfectly "whole". They came in black (early cars) and
then chromed plastic. They're not terribly well made and the lens (the switch "paddle") actually has as a mechanical as well
as electrical function. They often have a batch number and a date stamped on them (the black one says 78 and the others
are all from 1980). The lens says SEIMA 35 310 at the top and MADE IN FRANCE at the bottom. They were used on our
wedge cars, many early Renault vehicles from that time period, and apparently the first Hummer H1 has lights which fit too
but I don't know if they're the same. They came in lots of colors for the Renault version, and the Hummer version is just
black. For reference, the Renault part number is 7701349760, maybe someone else has the Hummer H1 version? One more
detail, the Renault lights have slightly thinner spade connectors, one bent the other way from the wedge door light. Accord-
ing to Ivan, the newest version of the Renault light remain the same from the front, but use a single three prong connector
for the electrical connection at the back.
So, what goes wrong? The little electrical roller contact on the lens sometimes pops off or (usually), the clips break off,
sometimes pretty dramatically. See the photos below right.
The clear lens can be pried out if you're careful (warm up the door light
with a hair dryer before trying this) and the roller contact replaced and the
contacts inside cleaned up (I used a bit of conducting grease on the roller to
keep corrosion away). As for broken clips, well, you can try velcro to hold
that side of the light in place on the door panel, I think. Anyone have any
good ideas on that?
Finally, there's the bulb itself. Since these lights are so fragile and rare,
next time a door light bulb burns out, replace it with an LED version of the
bulb. Victoria British stocks them (around $7 vs about 0.39 for an original),
and they're probably available elsewhere too. That way you'll never have to
pull that switch out of the door panel again! An LED light also won't get hot
and melt the lens like the original bulb usually does! Odd Hedberg sent me a nice quote about using LED bulbs: "If you do
it right - you don't have to do it twice!"
If you know of someone who has a box of these door lights somewhere in their garage, please let us know?

Decel/Bypass Valves- Jim Tencate
Triumph Wedge Owners Association December 2010
Decel/Bypass Valve Pulled Apart
How many times have you guys rebuilt these
things? The adjuster on the decel valve on the TR7 FASD'd
carb I just took apart had been turned out so far that the
adjustment nut INSIDE wasn't in place.
Incorrect Decel/Bypass Valve
And the rebuild kit gasket pieces? Crappy compared
with the quality of the old ones. I finally pulled them all
apart and compared with the new ones in the rebuild kit. In
spite of me thinking this decel/bypass valve was OK when I
first looked at it, it had clearly been apart once before *I*
checked it and had put back together wrong. We'll see what
the other one shows when I take it apart a bit later. The
FASD front carb was the one that (1) wasn't flowing well (if
at all) and (2) had a rag stuck in its side of the intake mani-
fold, neither of which is conducive to getting a TR7 running
correctly.
Maybe this (below) is obvious to everyone? You guys
are going to tell me I've been a "fuelie" for too long and
have forgotten my roots, right?
Decel /Bypass Valve Comparison
Original diaphragm is WAY stiffer than the replacements
in the rebuild kits I just got. The original is nicely intact
and in pretty good shape. The replacement seems VERY
flimsy, like it'd tear with one good blat and snap-throttle-
closed-after-a-hard-acceleration. I'm not impressed.
And when you pull the diaphragm gasket set all apart,
even the old *gaskets* are better quality than the paper
ones. I'm tempted to reuse the old ones as they seem to
be made out of some sort of phenolic instead of just pa-
per. But finally, look what I found when I looked inside
carefully. Look carefully at the photo, upper left, and
compare to the photo below. What’s wrong? Yup, the
adjustment nut had come out of its guide and then had
been put together wrong. THAT's why it was hard to turn
(besides just being hard to get to). See, that nut is sup-
posed to sit down in here (see below). I NEVER knew that
there was a shaped recess for it you know, probably be-
cause mine were always fine when I took them apart!
Learned something new! On to rebuild the other one so I
can get this car running tomorrow!

Headlight Relay Update– Odd Heberg
Triumph Wedge Owners Association December 2010
Odd Hedberg’s headlight relay article was well received by many of our TWOA members as over two dozen requested CD
copies of Odd’s article. One TWOA member Karl Schmitt of St. Louis MO had difficulty tracking down some the equivalent
parts Odd used in his headlight rebuild project here in the United States. The part in question was the “relays with a built in
fuse holder” which employs a “spade type fuse” . Odd has provided a sourrce for the part located in the UK called Vehicle
Wiring Products. The relay R30AF can be found at the URL below
http://www.vehicle-wiring-products.eu/VWP-onlinestore/relays/relays.php
And the fuses can be found at the URL below

As indicated in the TWOA Newsletter Issue #12 drop me a line at “[email protected]” and I will get a copy of the
CD out to you in the mail.
Wedge Heater Valves
Group 44 Archives Photos– Mike Perkins
Wedge heater valves are one of those parts that
falls into the No Longer Available category. There
are several options to adapt heater valves from
other cars to replace your leaking heater valve that
have been discussed in previous issues of the old
TR8CCA Newsletters. However, if you are persis-
tent you may be lucky enough to score what may have been the last NOS one
on eBay like I did. The seller clearly knew the rarity of the part and it was
priced with quite a high reserve price which the bidding did not meet. But con-
tacting the seller after the auction ended with a no sale resulted in a more rea-
sonable priced heater valve to replace my leaky one.

Here's another idea for a third light. One I purchased from Moss. California. A really nice chrome version that's supplied
with an equally nice chrome pedestal you'll though note I here didn't use. Only because I installed it on the luggage carrier.
An installation to which I gave considerable thought and placement. Not as you'll see on the lower rung of the carrier to avoid
compromising its strength; but under the top bar against which not too much pressure is experienced when in use. In instal-
lation I turned the third light upside down. Drilling two holes through the top bar through which I used longer bolts to attach
the third light. The longer separately purchased sourced male bolt excellently accommodating the female portion of the third
light: so not requiring holding nuts. As to wiring; it requires a third hole through the top bar. With the wiring running to the left
leg of the top bars support, down through the trunk lid to the cars brake light wiring. With all the installed wiring hidden within
the luggage carriers top bar and support leg: except if one looks really close to the inside of the luggage carriers left support
it is just noticeable. But look really close! As I chose black wiring: itself of excellent hiding quality. The most difficult portion
of installation was actually forming a not too large a hole through the left leg through which to pass the wiring down into the
trunk. But as it turned out, there was more than adequate metal not to worry about that aspect.
No luggage carrier! The very nice Moss third light could be mounted on its pedestal to the rear of the convertible top when
up; or the rear of the tonneau cover. Then in full view of following traffic I'll forward a second photo that's a close up of the
installation

More Third Brake Light Option– Mike Coe
More TR8 Valve Cover Options– Ed Krakowiak
Back in Issue #9 of the TWOA Newsletter I cov-
ered some options on valve covers for your TR8.
Well as it turns out there is one more option you can
use to dress up the engine compartment of your
TR8. If you acquire a set of “Rover” valve covers
from an earlier Land Rover they too can be polished
to a really nice finish. I was able to obtain a single
NOS one from the U.K for $1.99 and several used
ones for around $25.00 per set. You will need to
look at your current oil filler neck, oil breather canis-
ter and hose connections on your TR8 to determine
which Land Rover ones will work. There are several
different configurations I have come across so re-
view your set up before buying some used valve
covers. They all will fit on top of the cylinder head it
is just a matter of obtaining the correct one that al-
low you to install the oil filler neck, oil breather can-
ister and hoses.

Wedge Air Horns-Mike Coe
Triumph Wedge Owners Association December 2010
For another version of the electric radiator fan switch, I
thought members would be interested in how I've installed an
override switch on my 1982 TR8. Just an ordinary parts store
purchased switch: albeit one handling correct amperage and
wiring. With an incorporated light denoting the switch is on or
off. The double wiring threaded from under the dash and
through an existing firewall hole running to and fro the radia-
tor fan [an excellent fan purchased from Woody]. And notice-
able: the correct switch panel in which the switch it's installed,
is a panel I purchased from Rimmers when back visiting U.K.
relatives. I simply made a large enough hole to accommodate
the switch. The original panel that came with the car I
still have if anyone is in need of such an item. Mike Coe coe-
As a Bosch dual horn sound system controlled by the usual steering wheel button. But connected to a controlling switch on
the dash that can be switched back and forth to activate the sound of all three horns. Or an alternating musical sound of
each horn [the kids like to hear at a show for example]. The control switch as outlined in the photograph is third right from
the left. And a switch I purchased from Rimmer Bros. when I was last in the U.K. That's actually a headlight switch I
adapted for dual horn control. The only change I'd make to this arrangement is to swap the driving light switch with this horn
switch; as I occasionally forget to turn off the driving light by confusing my hands! So that'll be done this winter! Oh yes,
and the wiring is obviously back and forth through the firewall through an existing access hole. Plus I wired the horns to the
existing wiring at the cars front. And added a further switch at the cars front so as if one wishes, one can still use the horns
the car came with {but it's a bit redundant doing this}.
Two of the photos below show where I last year installed a triple horn system at the front left hand side of the engine bay
just behind the headlight.
Ebay Find-Ed Krakowiak
I found these on ebay and I thought they were kind of cool. Basically these are Rover decals for the valve covers on your
TR8 or Rover V8 that go on the rectangular area between the raised fins on the valve cover. I have seen “V8” ones before
but I have not been able to source them. So when these appeared on eBay from the UK I snapped up the set of four .

TR7 and TR8 Alternator Swap and Conversion –James Tencate and RandyTess
Triumph Wedge Owners Association December 2010
Background It's well-known that Jaguar/Rover/Triumph used some of the beefiest alternators that were available at the time for the
TR7 and TR8 but they're really not quite good enough. Like a good audio system, it's essential to have headroom and the
stock Lucas alternators aren't quite up to providing that electrical "headroom." Many of you have upgraded to a beefier
Delco-Remy alternator but there's nowhere you can go for a quick, concise summary of what to do. There IS an excellent
and thorough write-up for the TR7 conversion which has way more information than you may need to know at Greg Bober's
site. You may remember Greg, he's got a TR7 Spider and wrote the clock "repair" article for TWOA a while back. We're going
to assume that you can download his TR7 conversion article and read through it if you need more information or details than
provided here. The link is here for those of you near internet: http://www.smallscalerailway.com/
TR7_Alternator_7Sept08.pdf. Greg tabulated how much power the electrical stuff on his TR7 Spider typically con-
sumes; you'd be surprised at what he got when he added up all the numbers, almost more than the standard Lucas alterna-
tor can supply. So, we're suggesting you upgrade your wedge to a more modern, ubiquitous, readily-available alternator
that'll give you extra "headroom" and keep the Lucas original for Concours events. That's exactly what we have done and
that's the reason for this article. We note that there are a few old TR8CCA newsletters with Delco-Remy conversion details
too but that information is pretty scattered and old. Finally, there's a very nice YouTube video that's worth watching once
you read through this. Although it deals just with the TR8 and suggests a somewhat different wiring scheme with the sense
wire, it's quite good. It's here: http://www.youtube.com/watch?v=rPkhPbojUKs
The Alternator The easiest thing to do is to get an alternator for a 1993 GM/Saturn SL series cars equipped with the old 1.9 litre gas en-
gine. Actually Greg says any alternator from the years 1991-96 for this series Saturn will work. It's a Delco-Remy CS130
(which comes in several varieties from 85-105 amps). Greg's article gives you the Bosch equivalent part 8215 and other
cross-reference possibilities if you have trouble finding one. You can easily locate a remanufactured, a new, or a lifetime
warranty version at places like AutoZone, NAPAonline, RockAuto, etc. Be sure to get at least the 95 amp version however
since there's an 85 amp version out there too. Higher output versions are ok as well but not really necessary unless you've
added LOTS of electrically hungry killer stereo gear, etc. This alternator is about 3 pounds lighter than the stock 75 amp Lu-
cas A133 found on the TR8s, a bit smaller, and no additional brackets or mounting fussing are needed. Conversion/
swapping is a piece
of cake on a TR7, not
much harder on a
TR8. (Continued on
page 11.)

TR7 and TR8 Alternator Swap and Conversion –James Tencate and Randy Tess
Triumph Wedge Owners Association December 2010
You can also prowl eBay or your local "auto recycler" and find better bargains but be very careful to get the right
one. This is a very popular conversion for lots of older collectable cars so you might actually have trouble finding a junked
Saturn that still has its alternator. In addition, we'd like to make a recommendation: once you get an alternator from either
eBay or an auto recycler, take it and test it immediately. Jim, for example, got a really good deal from eBay on a remanufac-
tured alternator which looked beautiful, and the seller had lots of positive feedback and a good score. His great deal turned
sour. He put it in the car, it didn't seem to work, took it out, took it to Autozone for testing, and it failed all three tests. The
eBay seller, in the meantime, had disappeared off the face of the earth. Jim, somewhat wiser, at least has a core in case he
needs another one for one of his other wedge cars.
The V-belt pulley Alas, the stock Lucas V-belt pulley won't fit on the CS-130. The stock GM/Saturn alternator uses a serpentine belt pulley
and our wedges use a V-belt for accessory drive. It's easy to remove the serpentine belt pulley; any old impact "wrench" will
make quick work of removing the nut. Jim borrowed his neighbor's impact wrench, Randy had the guy at the alternator
shop do it. Greg says any V belt pulley from 2.5 inch to 3.6 inch diameter from a Ford from about 1975 to 1990 can be used
as long as the shaft hole is 0.67 inches. These used to be easy to find, it's much harder now. Jim used a 2.6 inch diameter
pulley he snagged off eBay after getting a too wide one that did NOT fit, Randy's alternator/starter shop just gave him one
which fit the first time. For those of you who care or may race your cars, Greg has an entire appendix discussing choice of
pulley size too. A larger diameter might be probably safer for those of you who race near redline.
Electrical connections You'll need a CS-130 alter-
nator pigtail to connect to
the Saturn alternator. You
can find one on eBay, or at
internet places like JayRac-
ing, or even AutoZone,
etc. Prices range from
about $8 to $15. Just
search on GM or Saturn
alternator pigtail with your
favorite search engine and
you'll likely turn something
up. There are eBay sellers
that offer this too. If you get
your alternator off a Saturn
from an Auto Recycler, take
the alternator harness plug
too.
Be sure to get the right pulley to match the width of your current belt and one of the right diame-
ter too.
Originally the TR8 electrical system used a battery sense lead that was connected to
the multi-pin connector located in the upper right hand corner of the passenger foot-
well. This didn't work out very well when that wire failed (leading to boiled/
overcharged batteries) so the Lucas Factory issued a service bulletin telling you to
CUT the thin brown sense lead midway in the harness and hook it up to the starter
battery terminal instead. You can remove the remaining sense lead inside the car as
you no longer need it. That leaves you with an extra always "hot" connection inside
the car for things like subwoofers, alarms and the like, and simplifies the wiring
somewhat too. There's a copy of this Lucas Factory Service Bulletin in the very 1st
TR8CCA newsletter if you'd like to read it. (continued on page 12.)
Jim got this pigtail for about $8 on eBay.

TR7 and TR8 Alternator Swap and Conversion –James Tencate and Randy Tess
Triumph Wedge Owners Association December 2010
Wiring the CS-130 is simple. Disconnect the battery if you haven't, reconnect it only when you're done. The pigtail has 4
wires, you only need 2 of them. Of course, there's also the main battery B+ terminal on the back of the alternator but we'll
talk about the pigtail connections first. They're labeled S, F, L, P Jim hooked up the fat red "S, Sense" lead on the pigtail to
the battery B+ post on the alternator rather than hooking to the Factory wiring thin brown sense lead. The fat brown battery
starter wire that goes to the B+ alternator terminal is a much more reliable battery sense than that thin brown wire which
snakes around the exhaust manifold. As noted already, the B+ battery terminal is also going to have the big fat brown fac-
tory wire from the starter/battery terminal. Now fold the existing factory wiring thin brown sense wire out of the way and tape
it up (it connects to the battery terminal on the starter so don't let it just dangle). (Jim kept this wire in case he wants to in-
stall the original alternator for Concours some day.) The brown/yellow striped wire of the original factory alternator wiring
connects to the dash IGN light and must be connected to the L (lamp) wire on the Saturn alternator pigtail, needed for the
alternator field current supply when the car is starting. See Wikipedia if you'd like to know what the dash light is for and why
the alternator needs this circuit. That's it! F and P on the pigtail aren't needed at all. Clip them and carefully heat shrink or
tape them up. F is field positive (used for fault diagnosis), and P is for Pulse (we think) and is used for tachometer connec-
tions we don't need. (continued on page 12.)
This is what the multi-pin connector/
junction in the corner of the passenger
foot well looks like without the protective
plastic cap. The original factory thin
brown sense lead is lower left. If the car
has been modified as per the Lucas Fac-
tory Service Bulletin, this wire can be
removed entirely. It's not needed for the
Saturn alternator conversion either. Use
the battery lead on the starter for the al-
ternator sense lead.
The wiring on Jim's alternator looks a bit messy still
but you can see the two wires from the connector hid-
den from view, the heavy red sense wire and the 3rd
brown wire which connects to the brown/yellow stripe
wire going to the dash light. The rubber boot protect-
ing the positive battery lead isn't the best but at least it
stops you from getting a wrench across that terminal
and the alternator bracket ground! Make all your con-
nections with the battery disconnected.

TR7 and TR8 Alternator Swap and Conversion –James Tencate and Randy Tess
Mounting details The alternator on the TR7 just bolts on, once the spacer is adjusted. Greg shows and describes this nicely, so we won't
repeat or discuss that here. However, on the TR8 the alternator must be re-clocked first and then you can adjust the spacer
for fit. The YouTube video shows this nicely and why it's necessary. Re-clocking is easily done with a star socket of the
right size. Remove three long screws holding the face of the alternator in place, rotate the head in the direction shown and
put the screws back in. There's really only one way to do it and we cannot imagine getting it wrong. One warning. If you've
got the pulley and nuts off while you're doing the re-clocking (like in the video), the whole alternator can come apart and the
brushes might pop out. Do the re-clocking with the fan and pulley and nut in place and you shouldn't have to worry about
the alternator coming apart. Once re-clocked, the spacer on the ear can be removed (see photo) and tapped back in the other
way around to fit the existing alternator bracket on the car perfectly.
Finally, that B+ terminal post on the alternator that has
the Red pigtail sense lead and the brown battery + ca-
ble? Please get a cover for the battery terminal on the
back of the alternator. It's very close to the mounting
bracket (which is ground)! Dorman 85684 or something
similar is a very good idea here. I found something
close at NAPA who had a drawer full of them.
After plugging everything in, tensioning the belt, recon-
nect the battery, start the car and enjoy your new elec-
trical headroom! James Tencate and Randy Tess
Above left-This pressed-in spacer on the rear alter-
nator mounting ear can be tapped out and repositioned
and tapped back in as needed so the alternator fits
snugly between the mounting bracket.
Above right and below right- Not much to the re-
clocking. Loosen the three screws holding the front
cover on, then rotate it in the direction shown and put
the screws back in. Careful not to let the alternator
come apart here or the brushes will pop out at the
back. You may find that the front cover is sealed to the
black paint if your alternator has been rebuilt recently
so it may take some coaxing. You'll also need a special
s ta r so cke t fo r th ese long sc rews .

TR8 ZS Carb Upgrade
Triumph Wedge Owners Association December 2010
Sure I would love to send my car off to Woody at the Wedge Shop for a full on make over. But until I win the lotto or find
a bunch Canadian Maple leafs gold coins buried in the ground with my metal detector that is not going to happen anytime
soon. I like to keep my TR8 stock looking in appearance as much as possible, but I also like to upgrade certain aspects of
the car in search of better handling, braking, acceleration, etc. Now the factory Zenith Stromberg carbs are one part of my
TR8 that I have never touched and consequently they have never given me any trouble. Now I have seen online where other
TR8 owners have upgraded or improved the stock Zenith Stromberg carbs but I was not sure exactly where to start.
I contacted TWOA member Paul MacDonald because I had seen pics of his TR8 ZS carb setup and I wanted to know what
ZS upgrades he had performed. Paul was a great resource and provided me with a complete list of what he used to up-
grade his ZS carbs. Here is list of parts needed along with cost and source:
2- K & N air filters #RC 2600. Summit Racing $70 set of 2 each plus shipping.
2– Non Standard Richer carb needles for use with headers. Rimmer Brothers UK #RB7468. $48.00 set of 2
2– #ERC9213 Early Land Rover UK Carb adapters. P.A. Blanchard & CO UK $90 set of 2
So for about $200. 00 I was able to obtain all the required parts need to upgrade the ZS carbs on my TR8. The first step
was to install the Land Rover Carb Adapters which bolt right on to the Zenith Stomberg carbs and then install K & N air high-
flow air filters. Once I installed the K & N air filters I took the car for test drive and noticed an improvement right away in
the acceleration of the car. Next I had a set of used TR8 Zenith Stomberg carbs I had acquired several years ago to keep
for spare parts. Before I did anything I marked which one was the driver side carb and which one was the passenger side
carb. I ended up pulling the dashpots and plungers off of them to use with the new set of carb needles I had purchased
from Rimmer Brothers. I removed the existing dashpots and plungers from my TR8 carefully marking which side was driver
and passenger. I wanted to save them in case I wanted to reinstall them to put the car back to stock or in case the new
setup gave me any issues. I also noted exactly the height the stock needles were set in the plunger. I used this as my base-
line because at this point because the car running great with the stock setup and had passed emissions before without any
issues. I installed the new Rimmer Brothers Non Standard needles in my spare plungers and set them at the same height
as the stock needles and gave the dashpots and plungers a good cleaning as well. Finally I installed the dashpots and
plungers with the new Rimmer Brothers Non Standard
carb needles into the respective carbs on my TR8. The
car fired right up and ran great. It was easily a full second
faster 0 to 60 now and the power band is much broader
coming on earlier and staying on longer than the stock
setup. I drove the car about 70 miles and pulled the plugs
and noted a slight lean condition. I richened up the carbs
just a bit and installed a new set of spark plugs and will re-
inspect them again and adjust if necessary.
This setup took some trail and error tuning to get the
car running right. That is why I kept the original dashpots
and needles on the side to set the carbs back to its origi-
nal spec if need be . The other concern is getting fresh
cold air to the K & N air filters. Here in the Midwest it is
not that big of an issue as it might be in the south.
