Message of my lack of the necessary components to do so. I'll see what I can do to post them using somebodies scanner or whatever I need. So I'll do my best to explain them: 1. I removed my SZ inconels and replaced them with MSP exhaust manifolds (that's all I did). The peak numbers with the MSPs was 505/518. The peak numbers with the Inconels was 523/542. 2. I added the Ash Spec piping and intercoolers to the MSP set up. The peak numbers were 547/521. The increase in area under the curve started at 3,000 rpm and continued to 6,500+ rpm. The gain was most significant from 3,500-6,500 RPM with 50 ft/lbs of additional TQ at 4,500 RPM. I believe the larger piping increases HP/TQ most significantly above 4,500 RPM. I think it costs some transient boost time (not indicated on dyno numbers). But my butt dyno (and actual dyno numbers) shows a significant increase in the engines ability to carry more HP all the way to redline.
