Well I finally got everything back together after a month and a half of waiting on parts, broken fans, etc, etc. Some of you know that I had torn my NA-T apart to have the head ported and polished, new Crower springs and retainers installed, new valve seals. I also decided to put in the larger 525cc injectors while everything was apart. I also redid the rest of the fuel rail with a new fuel pressure regulator and a dampener bypass, which I must say looks really nice.
Now most of you will say it isn't possible to run the 525cc injectors without a VPC or AEM but I'm here to tell you it can be done. With the head ported on both the intake and exhaust side and the manifolds on both sides port matched for optimum flow, I'm able to use the Lexus V8 AFM and a HKS S-AFR with the 525's and have a flat A/F ratio of 11.8 over my whole dyno curve.
Now for the rest of the numbers.
At 18psi I was able to put down 471rwhp and 448ft/lbs of torque.
If I can figure out how to upload the bitmap of the dyno curve I'll do so.
