Race gas numbers.
Race gas numbers are quite as impressive in the gain areas BUT there are some details that need to be known.
First, previously Peter's best race gas numbers and details were (stock ported intake/65 mm throttle body):
640 whp-535 ft lbs
20 psi at 4828
43.10 psi at 5930 rpm
37.47 psi at 8,000 rpm
AIT's 73.40 degrees
Average AFR, 11.55:1
Today after the Driven Innovations intake manifold, 3" throttle body, 3" upper i/ce pipe and 3" outlet on his BR Race FMIC he made:
650 whp-530 ft lbs
20 psi at 4797
42.55 psi at 5707 rpm
36.56 at 8,000 rpm
AIT's 66.20 degrees
Average AFR, 11.4:1
Something else that needs to be talked about is I did pull some timing out of the map this time. If you look at the two dyno sheets you will see where the baseline from before picked up some power at the very end of the curve. In this area today I could not leave the timing curve where it was and had to pull over 3 degrees out up top. So while the 10 whp gain in power doesn't sound like much at peak if you view the rest of the chart you will see there is a gain of almost 30 whp and 30 ft lbs around 6300 rpm and it slowly closes up from the timing being re-adjusted.
I just wasn't comfortable with the amount of knock the car had up around 8,000 rpm with the existing timing curve.
Here's the before and after dyno sheet on race gas.

Amazing job David.....just got off the phone with Peter and he was telling me about the thread and since i have been catching up the last day on reading about the intake manifold testing and his car i figured i would post up and tell you and Peter congrats! You guys are really pushing the envelope. i have got to say i am really impressed (especially as of the past 6-9 months) with how you have taken it to the next level with the tuning and tweaks to get that extra power.....great work!
heres the pics for ya btw Peter!
back to your scheduled hp record breaking program !
