Am I making less power for my boost than you'd expect?

[QUOTE="DRK HRS, post: 15559411, member: 175785"] I've been wondering about this, at peak power I'm making 486 rwhp on 14 PSI. This is with a P1SC from the Mach 1 kit. That's at like 6300 RPM or so. Apparently it keeps building more boost up until redline (17 PSI) but the blower is losing efficiency at that point and I actually make less power there. I am running an 03/04 Cobra short block so 8.5:1 compression, and the original Mach 1 heads which should be identical to Cobra heads. When I still had the original Mach 1 block, I was making 448 rwhp at 7-8 PSI. I think it was 10.1:1 compression. Is the CR making this big of a difference, or is it a combination of that and a crappy blower? I was expecting closer to the mid 500's to the tires. It's still a quick little DD street car, but my numbers seem off to me. This was measured on a Dynojet. [/QUOTE]
