I just got this car 3 weeks ago ... and decided I should get a Dyno Pull going so I can make sure its running well with the few modifications that I have found on it. I bought it from a dealer that said it was "stock minus the wheels" HAHAH.

Mods:

*Smooth Tubes
*Full Corsa 3" exhaust with High Flow Cats
*3.73 Rear Gears
*Dyno Tune
*20" HRE Wheels with 345/25/20 tires

It was 94 Degrees in the room ... OUCH!!!

Results were 425 hp / 460 tq @ the WHEELS, which is about 500 hp / 540 tq @ the ENGINE.

A/F Average was 12.27 ... is that pretty typical and normal (SAFE?) for a Naturally Aspirated Engine?

A/F Ratios seems constant, the runs were consistant, and I got the power I was HOPING for ... so I am a happy camper.

What type of 1/4 mile times should I be able to see with this kind of power? Is it enough that on a perfect run I can dip into the 11's? ( 11.99? ).

It lopes pretty good ... are they like that stock? Could it be the tune ... or maybe a cam? I can post a vid of it idling if that would help ... or would it put out more power if it was a cam upgrade?

I probably lost a few h.p. with the 3.73 gears and 20" wheels.

Thanks for the comments and for looking!!!

you should run mid 11 around 11.50 @ 124 mph with the mods!

Seems too rich for max HP.

Very nice, good looking car too.

Thanks guys.

I would rather run a tad rich and be safe ... I'm not going for all out HP ... but between the richness, the 3.73, and the 20" wheels I would be putting down a few more horses ---

I had a stock 97 gts and it dynod 423 rwhp. 469 rwtq and it only ran 12.29 1/4 mi, 60 ft 1.90s, 1/8mi 7.80s......that was with th factory tires....never tried slicks....

Thanks guys.......the 3.73, and the 20" wheels I would be putting down a few more horses ---

Gears and wheels size have no affect on HP numbers.

I was told that the gears take up a little more power to run when they are a higher ratio?

I was also told that if you run 18" wheels ... then run 20" wheels ... if the total diameter with the tire is more , you lose horsepower and torque because they are harder to spin?

Maybe I am just thinking with 1/4 mile times? ---
