Default H/C/I Dyno Results

first of all. a big thanks to bryan at pavlock performance for installing all this stuff. he's an awesome guy with great customer service and awesome prices. thanks a lot brother.

here's the deal. I bought the car last december with:
cam
mac mids
3.73
cold air
whisper lid
!egr
!air

as soon as I got it I got the rear end rebuilt with 4.10s and dyno tuned. and the guy I bought it from did not know what cam was in it. it made 336rwhp and 347rwtq on a mustang dyno.



what was just put in:
prc stage 1 ls6 heads w/ prc dual spring
ls6 intake
pacesetter lt's
hardened pr's
ls7 lifters
ls2 trays
160* thermostat

it made 399rwhp and 372rwtq...not sure what kind of dyno, but horsepower engineering out of houston did it. and like I said, I don't know what cam I have, but I didn't know if there was any way to determine the size. I didn't hit 300rwhp till 4k and peaked at 6200rpms. next mod on my list is a p&p tb, so that should put me at 400+ .



bottom line, I gained 63rwhp and 25rwtq from the heads, intake, and lt's (which were upgraded from mids). I'm happy with the overall #s. but I figured I woulda gained a lil more. let me know what yall think. thanks. Dan.

why do u say that? is it because of the spikes towards the peak power on the dyno graph?

sounds like a good choice and should get up in the power band quick with your set of 4.10's,remember to have your pistons fly cut just for some safe insurance
