That's with a STOCK exhaust manifold, folks! And a conservative tune. Also that dyno sheet is SAE Corrected, which will show the LOWEST results, unlike other, including vendors who post dynos that show the "best".

everything except for the gmr cams, vertical door hinges, return style fuel system, and ported intake manifold have been installed. Like Joe said, that's with a stock exhaust manifold. So respectable numbers are possible with the stock exhaust manifold.

Whoa.. is that on the stock tvs pulley? And what RPM?
I'm waiting for the chance to put my header on (thus running the manifold) and I see maybe 20.5psi at 7300.
I ported the crap out of my manifold a while back, but it wasn't 2psi worth!..lol

I have a 2.95" pulley installed right now. And I know 22.3 psi probably sounds like a lot, but the car doesn't feel like there is a choke point. She revs quickly and smoothly from 3k to 8k. The ported head does help a great deal, but the stock head does have something to do with the pressure being so high.

I'll say right now, I'm expecting lower numbers, probably in excess of 10 horsepower. two things..., the primaries are only 1.5 inches in diameter, and there are some nasty bends in the design. Three of the four runners have at least one bend in them that will disturb airflow to the downpipe. Before I install it on Sunday, I'll take pictures so you all can see what I'm talking about.
