You're just not close to the grip limit of your tires, which is fine (and recommended) on the street. Try an autocross course, slow, tight corner, and try to get it out of it in a hurry close to the grip limit.

I have yet to autocross. I'll have to try it and then report back.

"Doesn't Doug Lewis do a differential for the ATX?"


Nope. I wish.

There were some Phantom grip units that worked OK in the ATX cars, but given their failure rates on the ATX cars, I'm hesitant to offer them in the ATX flavors.

FWIW, Jason has one in his car (makes 330hp) and it's doing fine.

Out of curiosity, do you not want an MTX? I'd think it would be easier to drive, handle and would've been easier to turbocharge.

I would love a MTX, that might be my next SHO purchase if this one dies. do some math though, MTX donor car 750, quaife 1200-1500, a solid clutch and light weight flywheel 1K. i'm not a MTX wizz but i would imagine shot pine or cryo would be another 500. so what am i up to? 3750. assmuing no other parts are needed. the FPS unit was cheapier and may handle more power. you just have to put up with a ATX and trying to figure out how to cool it. i havent got it yet with my 12"X12" cooler.

I really want a LSD can we petition quafie to make us one for the ATX? like we did for the MTX or is there no demand for the ATX one? I realize that not too many ATX's make enough power to need one so I don't know.

No, Quaife $1245 plus install [no more than $150 if you pay a shop and bring in the trans], CM Stage 3 $550, Shotpeen $100, and that adds up to $1895 without the install of the Quaife and $2045 with install. You don't need a lightweight flywheel, but can get one for under $300 if needed, that'd make a maximum of $2350.

I heard they fail a lot in the MTX's, not the ATX's. If Jason's 330whp ATX has it, I'm pretty confident it'll hold up. I'm beginning to wish I went this route, and 3.98s. Oh well, next time....if this one ever dies.

I love to have one! My tranny including install was $3,117. Custom shift kit, custom torque converter...was told it was lighter weight (car does rev quicker though), etc, etc by Art Carr.

c'mon brian.... CM3+lightweight flywheel= :nono:

:biggrin:

clutch chatter? hmmm oh well, that give me something to think about for my next turboSHO.

was told it was lighter weight (car does rev quicker though),

I don't know if my converter was lightweight (i think it may have actually been heavier than stock) but it is quite a bit smaller in diameter + under drive pullies and I still don't notice a difference hahaha. in all fairness though I did add a turbo at the same time and MTX cams.

Didn't Fred Hurder still have a problem with shotpeened gears or was that someone else (or am I imagining this completely?)...or were they cryo?

You could always get Josh's HD gearset..$5K ? :)

To my knowledge, the only people that are running shot-peened gears are Tony and some of the Texas crew, and myself. None are broken yet. Cryo'd gears do nothing as far as I can tell.

There's at least one more set of the shot-peened gears up here in CO... Of course, they're not being put to use just yet.

Amazing how much extra power it seems to be able to hold as a result of the shot peening!

I think there've been a lot of nice, highly modified, Quaifed, fast MTX SHO's that have sold for a lot less than that for the whole car.

I would not go that far. Light mods, decent shape, and a Quaife maybe. I sold my 95 with a 3.0 BOS I, plus Stage I cams, Koni/Eibach and stock wheels for $5300, and it had deer damage, and no Quaife. If you could find me a SHO like that (which I would not classify as 'highly modified', WITH a Quaife, I would buy it for a 'lot less than $3117' in a heartbeat.

Most can't handle the kind of power my trans can handle. It's rated at 500hp/500tq according to the builder. He built Art's son's trans for his Grand National. 20 years later, many, many, many 10 second runs, it's still running like the day he had it put in. That, my friend, is a lot cheaper than mulitiple clutch replacements, Quaife, and Josh's $6k gearset. Sorry Eric, this is where the auto wins ;). Oh, and I pulled out of a slow corner, and mashed the gas. No wheelspin. The car downshifted, revs went up to about 4500, and the car pulled out nicely. I know this isn't a true test, but I'm just reporting on what happened this evening.

Wanna trade for a Gen I Mocha? :lol: I'd LOVE a turbo ATX!!

I don't think I could get $5K for my 93 with Quaife, 3.2, cams, brakes, color combo, etc. Remember, you sold your 95 a few years ago. The market has come down quite a bit. I bought my 94 atx for $10K and sold it a few years later (2002?) for $4900 after owning it for two years or so. It was very clean when I sold it.

Vadim at the SHO Shop tried a group buy on an ATX Quaife. He needed 25 people. I am sure if you approach Quiafe with 25 deposits, they will make a quaife for the ATX. The problem is to get 25 people commited to buy the diff. Good luck.

Since we know you have an open diff that probably means that you still weren't close to the grip limit of the tires, or you're not getting much torque to the wheels, or both. It's something you're not likely to see in typical street driving unless traction is real low due to rain, snow or whatever.

While there are certainly the exceptions that get reasonable money, there seem to be a number of examples that go for a lot less. The early GenI examples are creeping up on twenty years old...even nice examples, with Quaifes, have been known to go for not much money. Locally two of our AZSHO peeps picked up very nice GenIs for surprisingly low $$. It seems like these days the best bang-for-the-buck way to get a Quaife is to buy one already in an older SHO.
