PLEASE READ: - I was unsure how to log boost, and had our tuner take a look at it for me. It does indeed make more than 6 lbs. The kit has the standard Edelbrock pulley, but makes the following boost at these rpm's.
up to 4,500 rpms - 6 lbs.
5,000 rpms - 6.5 lbs.
5,500 rpms - 8 lbs.
6,000 rpms - 9.5 lbs.
so that's at 9.5 psi, not 6. 437rwhp/404rwtq
Found that.... Those numbers are not good... Whipples are making better numbers...
