Car put down 407rwhp 388rwtq. A/F is all over the place though. I have a few issues to work out with the fuel system and it should be making a little more power the way it is i think. Car is making about 8#s of boost. Here is the graph

Thats pretty good power for non-PI headed 4.6. What are you doing for a fuel system?
Chris
what all is done to the car? I see it has a keith craft forged motor?

Actually it is a PI headed car. Car has 99 PI Ported and Polished heads. SHM cams and the KC forged motor, and the usual bolt ons. All mods are listed on my website. As far as the fuel system. I am running an intank Walbro 255lph an inline T-rex, with 42# injecotrs. Problem we were having is the pumps are not getting enough voltage to work properly. I am going to rewire both of the pumps directly to the battery and spin the motor a little higher. I was hoping for my #s to be a tad bit higher being i have the cams and ported heads. Its making about 8#s of boost with a 10# pulley and a powerpipe.

Yeah I would really expect your car to make more power than what it is. If your not getting enough voltage to the pumps, they definetly need to be wired directly to the battery, and make sure that they are a GOOD ground.Originally posted by Juiced46

What kind of air fuel ratios did the shop tune your car to and what rpms did you spin the motor to? Even with 8psi I think the numbers are a little short, but my guess is, that it lies in the tune.

The A/F graph is on the dyno sheet i posted on the top. We spun it to around 6200-6300. I feel there is some room for improvement once all of the bugs are sorted out.

DUH! on my part.
That a/f ratio is real conservative, you have quite a bit to gain in the mid range, as well as uptop.
I wouldnt worry too much then over your lower power numbers, you have plenty left!
