Have 330 RWHP with CAI, Catback exhaust and tune. After the Kooks are installed,what kind of realistic HP gain could I expect? I will also dyno tune after the install.
40 rear wheel thats alot, you didnt do anything else?
Nothing else. The car had a CAI when I bought it. I had it dyno tuned a month later and it put down 325. Then I installed a 100 shot and some long tubes. It put down 365 NA and 430 on spray. Then I bumped it to a 150 shot and put down 500/530.
I do have a 2001 which has more restrictive exhaust, though, so I may have seen a bit bigger increase than an 02-04 would.... Still using the stock Ti catback (I have a Z06).

Reason: typo
Sounds a little low--but he is just being conservative --most cams will show at least 35 RWHP---so that should make you 55 total--after your LT's
PS How can he get 110 RWHP with a 100 shot flywheel rated NOS ??--A 100 shot NOS will show about 85 RWHP on a 6-speed after drivetrain loss --sorry but those #'s just don't make sense to me-

You're right, I went from 365 to 430 on the 100 shot. My bad. 500 on the 150 is right, though. I fixed it.
