Dynamometer Results & Comparisons - 00 SS H/C dyno

First off I want to thank Mike @ Gforce for a excellent tune! Jonathon and mike also chased down some issues i have been having with my car since day 1 and now it runs the best it ever has. So thanks guys.

I would like some input on my graph. My car made a little less power then i thought it would, but honestly it didn't bother me b/c i was more concerned about the drivability, but i would like some opinions just to feed my curiosity.

the car has some nice parts, which led me to think i would be at least in the 430 range. i do have a stock TB and pulley for whatever thats worth. it has a total of 25 degrees timing, 11.4:1 SCR. as you can see the graph kinda just flattens out up top (5600-6500). I suspect the short block might have some problems. oil pressure drops pretty low on occasion, but from one day to the next it changes. sometimes its normal (40lbs idle), sometimes its low (20lbs). anyway, let me know what you think. stock drive shaft, and rear end.

thoughts/opinions welcome. like i said, I'm just curious why it flattens out up top or if it looks normal?

Jon

Looks good! . . . A ported tb will help your torque curve a little bit..

i was thinking maybe the heads cant take advantage of the high lift cam, maybe even hurting performance, so its showing more in the higher RPM's?

Heck, I noticed quite the difference going to a ported stock TB on my mild bolt on car. You without a doubt are leaving numbers on the table without having the UDP and ported TB. That cam is designed, as are most I've seen, to run great with stock heads. Is that the F13 high lift? Your graph looks great. Over 400 rwhp fairly early on makes a great street car to me. Super smooth lines too.

Graph looks normal to me. The underdrive pully is worth at least 10rwhp & 10rwtq.

Mods in sig, I did 430rwhp/403rwtq.

ya i cant complain, the car runs great. i plan on getting a forged 347 soon. see if my theory about the bottom end being hurt is true. i might even take the car a completely different direction, who knows. I've always wanted a Procharger. :secret2:

any clips?

any clips?
Ya i have a clip on my Fquick page. exhaust is louder now that its been on for a couple thousand miles.

graph looks fine to me as well and #'s are respectable

TB and Pulley will get you another 10+ rwhp

sorry, I didn't see that you asked a question the first time i read your reply. Yes it is a High Lift F13-110LSA/ICL

lines being smooth is b/c the smoothing is set to 5

Thanks man, the car feels great on the road. I'll take it to the track and see what kinda times i can run.

nice numbers

i think that you would see your 430 number with the addition of a Fast 90/90 setup and UDP...the high lift cam focuses on the intake side and well i bet a Fast setup (although expensive as hell) would get you to your 430 rwhp goal or maybe even more. The graph is dead smooth until you get over 5500rpm then it starts getin a little bit bouncy, not too bad, but i bet thats from some restriction in the LS6 intake and stock tb....just my .02. Niice Setup though man.
