c6 horse power

Ruff estimate, what would a 06 vette with 1 3/4 long tube headers going into to 3in exhaust with xpipe and a cold air intake and a good tune..what would that make at the back tires?

LS2 should be about 355-365

LS3 should be about 375-385

RWHP

A bit more for stick, these are A6 numbers.

Just looked again - 2006 is LS2.

I thought we lost around 15% so RWHP on a stock manual ls3 was around 365 stock right? ..are you saying that you gain around 10 to 20 RWHP with headers, intake and tune? Seems a little low?
I would think more like 395 RWHP ..??? Hell I dont know I need to go get my dyno'd.....LOL

Yeah that's what I was thinking, you loose 14% so if it has 400 stock then to the wheels that would be like 346 to the wheels? So I was guessing around that to

With just headers, (with high flow cats), cai, ud pulley, and a tune, I dyno'd on a mustang dyno at 360. After the cam, fast 102, and 3200 yank I am at 420. Both readings were in the peak of the summer 95 degree temps. So they may be a little low.

Most LS2 M6's will dyno 335-345 from the factory. Headers and tune will get near 380ish.

True, but mine is an A6. Your numbers are exactly what I have been saying.

I agree, autos will dyno a bit less. My 384/392 was with ported TB and LS2 intake which most likely accounts for 15ish rwhp over your numbers (even with UD pulley).
