Take it to the track and see how it runs. Dyno numbers dont mean much. My truck went 13.1 when it made 389rwhp and 12.7 with 510hp.

Ya that doesnt seem right, I thought maybe you were running some monster tire.

Its all in the gear size believe it or not. There is a twin turbocharged built mustang here running atleast 1000hp and he dont show it on the dyno due to running a low gear. Turbos like a high gear such as 3.42s or even higher.

Did anyone notice he is only running 6#s of boost? Nobody asked if its a load bearing dyno, that would skew the results too with a turbo.

6psi is what i would run on a STOCK motor.. bump that up.

what compression is the engine at? 6psi may not even be near what the engine wants to see.

for example, my 408 is at 8.5cr, at 5psi i wanted to throw it away, 10psi felt strong, but at 18psi it's a monster!!!!

I looked but did not see, but what trans are you running... 6psi, 20's and the gearing, along with an 80e could def kill numbers....but that still seems a little low??

And these guys are right...track numbers are what matters.. my 421hp 60e trans am killed a many a 450-460hp 6 speed cars.. lol
