Being that i am getting ready for a tune and some dyno time, i hav ebeen on a few sites looking up differnet peopels dyno numbers to try and see around where i think i will be. I am curious on what your guys' estimates are on my setup.
Stock bottom LQ4
232/234 .595/.598 Cam
Hand ported 862 Casting 5.3L heads - (around 10.8:1 compression)
Brain Tooley dual valve springs
Comp Cams chromolly pushrods
LS9 Head Gaskets LS1 Intake
LS1 Ex. Headers w/ 2.5" dual exhaust
Looking for numbers off the bottle ... not with the spray. Thoughts?

No tune, and no accessories? Id expect 320 range but easily a bit more with a tune.
It shall be tuned when on the dyno. Hoping to break 350
315 hp on a dreamkiller...
Yeah, on a Superflow, I'd expect around 320hp
What trans? Can the converter be locked if it's a auto? I know it's a xer lobe cam, but what lsa, icl? Is that stock ls1 manifolds or actual long tubes? Who ported the heads, valve size, flow numbers and what chamber volume? I'd like to calculate the dcr to get a better idea, but it's really hard to say if a unlocked auto.
If it's a unlocked auto like a t350 or t400(think you had a t350) I'm sure it won't dyno really high, but still run very hard at the track. Dependinng on how tight/loose the converter is, etc will change the number so much. If it was a manual I'd say it would do a little over 400whp on a dynojet (410-430 or so). That size cam on a really good ported 243 would make over 450 if the dcr was strong, but the dished pistons of a lq4 don't give the best quench either so. Car should fly on the bottle though if everythings working right.
02' TT Z06
00' Audi S4
02' Tundra
02' Honda Superhawk slow, but sounds fast
Trans is a t350. Converter is a TCI with a 3500 stall and anti-balooning plate. LSA of the cam is a 112 Stock ls1 manifolds not long tubes. Valve size is the stock 1.89" intake (which is going to kill me i know) and exhaust valve is 1.55" Never got flow numbers after the porting. Chamber volume is 61cc.
The 5.3 with the same setup except a 04 z06 cam and valve springs and the heads were unported through the same trans and converter put down 290hp / 280 tq
On what dyno?
