rwhp estimate?

[jag42420]

I have installed (or in the state of being installed) on my 02 WS6: (stock LS6 intake) SLP lid, homemade airbox to hood seal & removed rear baffle from hood, P&P TB, Pacesetter headers, Bassani dual ehaust, no cats, HP Tuners, 3500 stall w/24K gvw cooler. Any estimates on the rwhp range I should be in? We have no local tuners, and I'd have to travel at least 2 hours or so to get to one... Anyone with a similar setup?

I'm thinking 310-320ish stock, +15-20 for the bassani (from dyno tests I've seen in the forums), +15-20ish for the Pacesetters and cat removal, +15 for the P&P/ SLP lid/airbox seal/debaffled hood, and maybe another 10 from tuning? That would be somewhere from 365-385?

Later this year I'll be adding a cam & heads package for some real power gains.

With an A4 the dyno would probably be around that 310 to 320 you think you made stock. With the cam and a tune you should be around the 365-385. Autos dyno low and you can't just add up mods. Like 15 for exhaust + 15 for headers = x. It doesn't work that way. Also did you say you installed an LS6 intake? Or were you just pointing out the fact your car had one stock.

No.

My guess with those mods through an A4 tuned will be 340 RWHP. Stall and automatic eat dyno results but lower your track times.

Just pointing out it was stock.

I'm still in the process of installing most of these upgrades (namely the 3500 stall, Bassani duals, Pacesetter LTs, HP Tuners software), some are still sitting in the garage floor right now. Adding the SLP lid, porting the TB, sealing the airbox to the hood and debaffling made a noticeable throttle response difference. I'm just wondering what kind of gain I can expect when I get them all installed and tuned in. This WS6 feels alot faster even pre-modifying than most other cars I've built up with in the past. My WS6 has yet to see the track, but I've seen how these stock LS1s tend to run high 12s to low or mid 13s. I want to wait to take mine to the track after I've installed the goodies...

I've built several cars, but this is my first fuel injected computer controlled car. It's the first one that I could reprogram the computer without having a new chip burned for every new mod. I have built a 70 SS Camaro with a LS6 454, a 79 Camaro with a 383, 87 & 88 SS Monte Carlos with 305s, a 48 Chevy street rod with a 350, and assisted numerous buddies with theirs. I've never ran a car on a dyno, mainly because there are none around where I live. We've always used track performance data and tweaked until we go what we wanted. My family owns a local machine shop, and I grew up working there. I love muscle cars and raw power.

I'd like to get my WS6 solidly into the mid 12s. I've read various LS1 forums, and am hoping my new parts should get me there with sticky tires.

[Ripper415]

i'd guess around 340-350 rwhp. i'd suggest getting a cai kit like the fast toys or the ssra (NOT THE SLP, ITS CRAP). that should get you another 10 hp. everything combined with the stall and auto should have you solidly into the 12's. getting sticky tires and doing suspension mods to increase traction like a torque arm could get you another few tenths.

what does cia stand for?

I tried to find a BGRA setup, but I'm evidently in a long waiting line. I can't believe someone has not started making them again. I looked at the FTRA systems, but ended up debaffling my hood (2nd baffle only) and sealing it to the airbox using a homemade setup a cutout from foam. It changed responsiveness and the sound dramatically. You can hear the vacuum from anywhere near the car now when it's running.

[jag42420]

I bet with some SLP HP stickers I could drop a full second...

[BayAreaSS]

i say about 335ish

[jlashley2001ss]

yeah im sayin 330-335 range. same mods i had when i dyno'd. with my cam(224/228 .581/.588 110+2) y-pipe setup(dynomouth), LTs/lid/ported stock TB/LS6 intake/SY3500 stall i hit 370rwhp which is pretty good i think considering i have A4 with stall. What you think guys?

Thats what im guessing man........355-370 on a m6 car mayb......but ur car is an auto which dropps rwhp....and stalled so it messes up dyno reads too.....

with my car......a4 3500 stall..."big" Torquer v2 cam and full bolt ons (Headers, lid and exhaust...) Im making 370rwhp with a real nice tune.....
I have a ls1 intake so that changes it allot but still man.........the a4 sucks up a bunch of power from the rear
