Where do you think I am now?

OK I got a lot done last weekend and am curious where I should be at and am asking for help.

1998 Z28 A4

Volant CAI, Pacesetter LT's, !air, !egr, ORY, Borla Catback, 3.73 gears and LS6 intake. I did not get a tune yet, that is coming with tax return money. Where do you think I am before tune and what about after the tune.

Thanks everyone

325 without a tune, 340'ish with.. Depending on which dyno you go to..

Dyno numbers dont really mean **** in the real world though.. They are a tuning tool and the numbers should only correspond to positive or negative progress both in peak and under the curve numbers.

Um, not trying to hack your thread or anything, but if these are the numbers what is the rwhp stock?!?!?!?! The motor is 325hp w/ RAM air package. So he would only gain 15hp here??? WTF!!!

The 325 is rated at the flywheel. In wheel hp numbers an auto dynos stock between about 290-310. Manual cars have less drivetrain power loss so they tend to dyno a little higher, probably between 300-320 stock. Factoring in drivetrain loss of even 10% on the manual, thats 350 hp at the flywheel. So they were under-rated stock

^^^ So, with that being said, I imagine it's safe to assume a full bolt on LS1 would be making around low 4xx range at the crank?^^^

@ Conor, If you take the math of 18% average drivetrain loss, then multiply it by the rwhp it should give approximate crank hp, also take into account friction, higher stall torque converters and gear and rear end differences. My car made 340 rwhp through a yank 3200 converter and 3.73 gears. So I figured 19% loss, which gave me 401.6 crank hp.
