Anyone have a brief list of LS1 mods with the estimated HP ratings??
How much would you say my car is making with my current mods???
I'm guessing like 350 FWHP?? maybe like 315 to the ground i guess?

seems like you might have more. i read a post somewhere about some LS1 Engines were MONSTER POWERHOUSES for some odd reason, cuz they were built at a different plant. I have a stock engine Z28 and when i had it dynoed, i got 305 hp to the ground. i didnt think this was right at all cuz that is the numbers for at the flywheel. so i took it to two more shops and god the same answer 305 to the ground. i would think that with your mods you would have a bit more than 315 at the pavement.

In a 2000 without a lid and with that restrictive Flowmaster on there, maybe around 300rwhp. Get a lid and cutout and you could see 315. 2000's won't dyno quite as high as an 01/02 due to the LS6 intake and better exhaust manifolds. Do those few mods and you'll be right where you should.

Your numbers are right around the average. The f-bodies, especially the Z28 and formula, are severly underrated by GM to make the vette look more powerful. Vettes and f-bodies dyno just about the same FYI.

315 rwhp may be a pretty accurate # especially w/ the M6 cars...

my 98z28 m6 with lid, borla, put down 315 so id say your right on!

as for HP per mod its hard to say? there are lots of factors to concider....
year of car, m6-a4, milage, and order of mods etc...
but ill try to help a little...these are just me guesses...

stock 285rwhp 330fwhp
lid/filter 300rwhp 348fwhp
free mods 305rwhp 353fwhp
ported TB 308rwhp 357fwhp
cat-back 315rwhp 365fwhp
Bellows 318rwhp 368fwhp
long tubes 325rwhp 377fwhp
cut-out 330rwhp 382fwhp
224 cam 360rwhp 417fwhp
S2 heads 380rwhp 440fwhp
ls6 intake 390rwhp 452fwhp
tuning ** 400-420 rwhp 465-485 FLYWHEEL HP

tuning after almost any mod will raise numbers!
