I have a '93 3rd Gen with some mild mods: 8.5 lb flywheel, DP, Catback, PMS computer,Intake w/ K&Ns, boost is 12-14-12 on twin seq. turbos.

It runs really strong, but I have not had an opportunity to have it dynoed or taken to the drags. Does anyone have a similiar set up? And do you know the approx rear wheel HP (I've been told its about 360) and what it will do in the 1/4 mile?

My mods are pfc, dp, mp, cb and cold air intake and running approx 13.2 boost I ran a 12.79 @ 114.5 mph in the 1/4 on stock wheels.

wmrobert

That sounds about right. Have you had your tt dynoed?

Do you mean 14-12-14?- you should dip a little at transition 12-14-12 doesn't sound right unless you're spiking. 360 rwhp is pretty optimistic with your mods but could be close at the flywheel - I'd guess around 270-300 rwhp. Your flywheel doesn't add peak hp but will make the car feel much quicker and accelerate much faster once you're going. Without some kind of cat (HF cat or MP) you lose a lot of hp but I'd say you're in the very high 12s.

My guess at would be more like 280 rwhp at best.
That is a strange boost pattern.

Yea, my boost is 12 - 14- 12. I must have had a bout with dislexia while typing.

what kind of improvement do u think u'd get with a new IC?

MichRX7

Don't know, I have read about 30 degrees cooler with a good fmic and I know I get really warm when the temperature is up there. It is on my list of "to-do's" for this winter as my car is in the garage right now getting ready for me to start ripping and stripping.

It's still backwards...14-12-14 the middle number is where the transistion is a "DIP"

I ran 12psi on primary and 13psi on secondary and my rwhp was 301.

NM- misread post.

unless you got a very very strong engine and some really really good tuning i doubt you'll come anywhere close to 360. without intake i was making 242 on a very very old engine w/o tuning of the pfc. throw in the intake and some tuning maybe 260 tops. with a stronger engine maybe 270 or 280 for you.

Maybe you're making a false assumption that all cars have to dip on transition. Its actually a variable mostly dependent on how prespool of the secondary turbo is handled and can go both ways. My car doesn't dip at all at transition and actually spikes slightly during the transition period. Even my dyno sheets prove this to be the case.

Robert I ran a 12.06 @114 last Friday with the PFS PMS, intake, intercooler, down pipe, high flow cat and cat back & Mickey Thompson ET Streets. You did not mention your intercooler. Is that PFS too? If so, spend your money on tuning rather than more pieces.

You need serious tuning to get the most out of these mods but they have the potential to get you to the low 12s and maybe a little better, at least that is my experience. I have a ported motor so that one difference, but your mods are fine.

In general, to go much faster than 12 you would need a mid-pipe and a probably a non-sequential set up.

That 360 number that gets bounced around is at the flywheel, not the ground. I think I make around 325HP at the rear wheels but that's with a lot of attention from Peter Farrell & Ray Wilson.
