I don't have access to an AWD dyno and was wondering if anyone had guesses to what my HP would be
2001 RS Sedan with 4eat (TC modded by Protorque)
Cobb CAI
Borla Header (wrapped and silicon sprayed)
Random Tech Hi-Flow Cat
Cobb Cat back exhaust with mid pipe (identical to Stromung)
GFB Pulleys
Magnecor Wires/NGK Irdium plugs

Probably 120-125 at the wheels

Well, Autos have more driveline loss than MT

hey there i have the following

ganza flow intake
k&n filter
2.25 5zigen catback exhaust

and most of it is stock and the meter said that in third gear switching to fourth i hit 145hp at like 3500 rpm. i 'm not quite to sure if it is right. but it gives me some idea of were i am at but who knows i could be at like 130hp or something at the wheels you never know what and who you can believe on hp everybody drives different so you dont know what you can get unless you do it yourself.

If I were to take a big fat guess:
Cobb Exhaust: 5 HP
Borla Headers: 5 HP
Random Cats: 4 HP
CAI: 7 HP
Ignition: 2 HP

+165HP
=188HP at the crank

Again, just a big fat guess, don't let the AT pundits get you down

Umm.. Im not a AT Pundit, but it is proven that ATs have more driveline loss. Start a poll if you like..

I agree, it's been discussed before. AT's do have slightly more drivetrain loss. It doesn't make them any more or less a good car though.

No. Letting an engineer 7,000 miles away and 15 years behind you decide when you shift makes it a lesser car. :D

NABEAST, what do you want SVXR8DR to do? Convert to a 5M? He can't, it's too expensive, so allow him to make more horsepower. I have a 5M, but I don't make hay by busting on 4EATs.

i have a 98' rs 2.5 DOHC with

JC Sports intake cai
Brullen header and high flow cat

with 55 shot Zex n2o got 180whp 205trq

dont know if that helps

o ya, got a 14.5@95mph in the 1/4 with a slipping clutch

Thats odd that your car has 140 hp with such minimal mods, Patrick Olsons Legacy has Cobb Heads and Cams and only has 3.5 more hp than you..

Post it as a link then. Thats pretty interesting and actually giving me some N/A hope.. If you can produce those numbers with what you have, then 170 or so whp isn't impossible.. I plan on bumping up my compression, Buyng Cobb Mild Cams and Heads, and hopefully get my hands on a SYMS Intake Manifold.

Since you have what is basically the COBB Stage 2 Power Package with a few brand differences I would estimate around an additional 20-25 h.p. My car with an older version of the Stage 2 Power Package (old version of the Random Tech cat) made 22 extra h.p. and ft/lbs of torque to the ground.
