Default 99 HP estimate :(

Hey guys, have a 99 Z28 that ran 311 HP with 318 tq.

The only mods I had at the time were my 3600 stall, a lid, and a really shitty true dual setup (on stock intake manifolds).

Currently, I have an LS6 intake, Pacesetters, and sweet thunder true dual setup on the way.

What can I reasonably expect to make on the dyno? I was surprised I pulled out 311 hp in a mildly stalled auto.

Thanks!

Is 350-355 whp out of the question?

yea im suprised you dynoed that before too....with what you dynoed before i would guess 350hp wouldnt be out of the quesion but im going to have to guess it will probably be more around 340-350....normaly i wouldnt even say that but you had a damn good base so....just my 02c let us know

311hp in a stalled auto with your mods and not even a ls6 intake sounds pretty damn good for a starting point

sounds like a happy dyno or you got lucky and got a "wednesday" built car haha

Yeah, I'm not sure.. it could easily have been a happy dyno, it was about 90 degrees in the shade (beginning of AZ summer last year). Had the massive fans blowing however, so not sure.

Thanks for the replies

EDIT: Haha, "Wednesday" built car, I like that phrase, I might steal that one

i don't know about hitting your 350whp, i just got dyno'd to day i have a full exhaust, cammed 02 z28 so i already have the ls6 intake, and i hit 362-370, just my guess but with no cam i personally don't see it but hell some guys with my setup are seeing way higher numbers than me, so who knows.

Woah... you have heads and a cam with bolt ons and you are only seeing 370 to the wheels?

What was your baseline dyno? Also, did you do your dyno pulls on a mustang dyno? Those numbers would sound more reasonable in that case.

My numbers were from a dynojet.

He's running 243 heads and its through a 12 bolt. I can see the 370 if they are unported
