I know he has a killer traction problem, but traps well into the 120's.

Have you dynoed it or have any estimate on power

I am going on a guess of atleast 450RWHP, but I am not sure if Bob has ever dynoed it.

I have always liked the twin turbo Supras.

So have I, and his is a fine speciman.

Infact Bob its been a while since I have ridden in your car I am about due for another ride. Maybe this weekend if its back together?

If you go with gears & slicks you had better go with a Ford rear end.

A Moser 12 bolt does the job just fine.

As long as you don't go over 3.73's with slicks you will be OK the stock Rear will hold. If you do DR's instead of slicks you could do 4.10's. Seen 100+ cars with this set up.

93 is the year they changed the body and added another turbo. I used to have a 90 Supra Turbo, but I had so many problems with it I got rid of it. What was wrong with your project Supra?

I had a 88 Tyrbo Supra and the damn thing went thru 3 engines before I sold the F'in thing. The guys at the dealer told me all alot of the gen 3 Supra's had problems because of oiling restrictions in the motor. I know first hand about that. I liked the way they looked and with some mods it was a reasonably fast car high 13's but 3 engines in 2 years...

As for Bob's Supra It's a beautifull example or it was till someone rear ended his butt Hope to see it out next time.

I did the exact same thing, blew two engines in two years. I ended up selling it to the head mechanic at the Toyota dealership without an engine. My mom still has a 90 Supra with 160k miles on the original motor, but it doesn't have a turbo.

[WhiteT78Supra]

It's the newer body style.

I have never had it on the dyno but it should be around 550 rwhp at 17 pounds of boost.

I have the rearend fixed now. I am just waiting for my new GReddy 4 row frontmount intercooler and my FJO wide band O2 to come in. I am hopeing for just under 700 rwhp with a little tuning and some more boost.

I can name 5+ guys off the top of my head that are well into the 10's(10.66's, 10.88's, etc.) with the stock "rubber band rear ends") The automatic equipped LS1's can go much faster without grenading their rear ends. I say get a 3000-3500 stall, and you'll have 12's easy.

The Vettes do have longitudinally engineered better exhaust systems while the F-Bodies have those transverse things that (by almost anybody's criterion suck badly) and rob power from the Vette ratings. Not a flame. I know that almost anyone with any knowledge agrees with that.

Yea i know of some guys here at Moroso that run real quick with A4s and stock rear ends. That is why i bought the auto b/c i knew i would be draging it alot. I'm not sure which route i want to go with the car. I am thinking a stall though, but i don;t want to run into traction issues. I will research it and find the best way to go. The stall though looks real good right now though.

Thanks for the reply's

One guy in my area has broke 2 rubber bands all by himself. He runs MT ET streets and 3:73 rear. His is a stick. None of the stangs in my area have rear end problems, except 1 7.5 inch rear and one auburn unit gone south. i would be gentle with it, but I would also trade it for a Stang.

Oh, jesus, thanks alot. For a moment, I thought folks we'are gonna question those goofy transverse exhaust systems? Pfwew, maybe we got by that one?

No it's true. Thats why the quad center exit SLP system picks up so much HP on the SS. I forgot to mention it on my original post about the Diff. between them thanks for adding it

I wouldn't touch the gears. With a 2.73 rear you have about the same contact area as a 4.10 Ford 9" rear. Go with a good sized stall with high STR to take advantage of the 2.73 rear gears. On LS1.com in the group purchases section check out the post about a GP on the MidWest torque converters. I used a 3200 2.5 STR MidWest converter in my 99 Z28 A4 3.23 car. I went from 13.1s @ 107mph to 12.2s @ 111mph from the converter on stock tires. I would go with a 3500-3600 with 3.0 STR and your car will fly. I drove mine 104 miles for work every day and the stall was not an issue.


Jess


P.S. I forgot to mention the price is around $450 for the converter. Cheaper than gears, install and a speedo calibration device.

I have been looking for you forever, well at least since i got my car. I remember your car well, and it was an inspiration for me to buy an Auto. No lie. It was red right?

I was wanting to talk with you, and get your thoughts. I will send an PM and get ur email. Glad i ran into you!

Jess, much like Ezridn I have (had) followed your camaro (no former camaro) very close. I found the times that it ran awsome and respect your input. My question is do you think he is better sticking with the 2.73's rather than swapping to 3.42's (what I would think would work best). I just figured the 3.42 would help it out giving a better power band as it crosses the line in third. I figured this would play a even larger part if (when) he adds more performance parts which only help the higher RPM's.

Just wanted to stir your head a little and gain a little info.

Thanks.

[LeadSled1]

Yep, it was red. I'm flattered guys, thanks!


Honestly, I would stick with the 2.73s for a bolt on/modified car. A high torque multiplier (STR) of 3.0 would do an awesome job getting the car off the line. Next I would have a higher stall of 3500-3600 to help overcome the gears on the top end and give you a better shift extention (RPMS do not drop as far on the shift. You will probably come into each gear at 4200rpms). The higher stall speed will do the same for you as gears do when going through the traps as the 4L60E does not lock up in 3rd like the AOD/AODE trannies do. But, by using more stall and sticking with the 2.73s you will have a strong rear vs the 3.42 rear.


It's a lot different than the Mustang setup and alot of people are not used to it. I'm actually going in the opposite direction with my 93 AOD coupe. The difference is that if I were to stay with the old 2.73s my coupe has but use a high stall/STR converter it would be great in 1st and 2nd but when lockup occured in 3rd my rpms would drop way down since the difference between a high stall & 2nd gear and a locked 3rd gear would be huge. What I did instead is to go with 3.73s and a high STR (3.0) with a low stall (2800). This way I have the power of the torque multiplication off the line, The 3.73s and 2800 stall help with the shift extention and when 3rd locks up There isn't too much stall difference coming off of second that the 3.73s won't be able to help make up in 3rd.


Sorry there's so much but there is much more to converters than alot of people think about.

A better site to check out for GOOD LS1 info also is www.LS1tech.com and www.converter.cc and go to the dyno section to see some conveters in action and what STR does for you.

My E-mail on this board has to be updated. You can reach me at work at jesse.o.guilbault@chase.com if you need more info. I'll be at that addy until 10:30PM week nights.

"I went from 13.1s @ 107mph to 12.2s @ 111mph from the converter on stock tires." Holy crap that is a damn good mod. I wish a converter would pick up that much time on my car!

[Rev]

Uhm, I wouldn't count on it FivepointOH, it didn't do that for me.

Rev

[LeadSled1]

Thats the thing with the 5.0s. The long runner intakes make good torque off the line. The LS1s make their torque higher up in the rpms. You use the converter to skip the weak part of the rpm band down low.

While a converter will help an AOD car it does more for the LS1s


Jess

[Rev]

LS1, the problem as I see it with the high stall converter (3000 or above) is in driveability, no matter which car it's in. For normal driving, it will never be locked up, always slipping, especially with that 2.73. You just can't accomodate a really high rear end with a high stall converter in every day driving. I think most everyone will see that.
