Dynamometer Results & Comparisons - How much power will this car make???

Its a 99 T/A that my buddy has bought. He thinks it should put down around 400rwhp and I said around 360rwhp........what do you guys think? And why? Here are the specs........

99 trans am
m6
t-tops
gray leather
34k
ws6 hood
fikse fm-5 wheels 11's in the back
goodyear gs-d3 tires less than 500 miles
eibach pro kit
pro-fab lower control arms
spohn adjustable pan hard bar
G5X1 cam 228/232 .585/.595-112 lsa
porter ls6 oil pump
patriot valve springs
new timing chain
ls6 intake
qtp 1 3/4" long tube headers
qtp 3" into 4" collector y-pipe with dual electric cut outs
slp loud mouth with bullitt muffler welded in
spec stage 4 clutch

My old set up was full boltons with a tr224 and it made 392rwhp and 383 rwtq. So I would say with the cutout open he's right around the 400 mark.

With these options is say 500 RWHP :jest: but without these i would say 380-390 rwhp

Yeah..........my buddy saw this post and asked why I posted all that crap when It doesn't apply to the question, I cut and pasted it from the sale discription and didn't delete the crap............my bad. :eyes:

Yeah.........I had a good time too. Didn't have enough time to spend there though. Your friend with the T/A was pretty cool too.

So did your T/A arrive yet? I got my car back and it's running great. I need to find a way to adjust my clutch pedal though. Its adjusted to the top of the pedal and the shop said the adjustable master cylinder has been adjusted all the way down................so basically it cant get adjusted any lower. :eek2: And its already shifting at the top of the pedal. Its very annoying. Its grabbing hard though. :devil: I'll send you mpegs of the header install.

I'll bet 370 to the wheels..........

i'd say 360 to the wheels. Without a good set of heads, he's going to be very limited. He's going to need a good set of heads to get him to 400. Throw on a 90mm setup and he'll be around 410-420 with a good tune.

Depends strongly on the tune. Don't see a ported TB or UD pulley either. With a razor sharp tune, he's looking at 385-395 rwhp. Add the other components and the power should rise another 10 rwhp.

Do your research bud, what you're saying is retarded. I'll bet he his 385-390+ Stock ls1 heads arent bad at all. So to say his heads are limiting him is just wrong. Look at my mods in my sig, and guess what I put down ? I have stock ls1 heads too.

Ditto...I put down 420/395 to the wheels with stock 806 castings and a broke dick cluctch. With my tune finalized and a new RPS clutch I'll guarantee 430 to the wheels with 806 castings. but my heads are holding me back right?

I'm right at 345 area(don't have slip here) with mods in sig before the stall converter. If I had a M6 I would be over 360 rwhp, so I'd say it should be over 385rwhp. These cars can vary so is hard to tell.
