CPR's C6Z Alpha heads/cam package makes 587 rwhp in AZ!

So we have done a lot of different packages throughout the years and this one time and time again just flat out performs even w/ our terrible 91 octane, high DA, high outside temps, etc. The cam is not tiny or any odd claims like that, it does however drive extremely well ie no bucking on the freeway, on the street etc. Only very slightly if your going to slow in a parking lot or don't know how to modulate the throttle/ls7 with a cam'd ls7. I'd compare it to a torquer cam. This package is built around the following components but sometimes people already have headers or a CAI and that can slightly affect final hp numbers, but they always land extremely close to the 580 rwhp mark. The graph shows 91 vs torco.

Setup includes the following. 
Our Alpha cam
WCCH heads
ARH 2'' headers w/ or w/o cats 
Airaid or Halltech intake
Fast 102 or MSD airforce 
102 TB

That's it no underdrive, stock mufflers, stock compression, etc. 

This car in the video's below made 587 rwhp and 506 rwtq on a very hot day (run conditions on the graph) and over 600 rwhp when we put some torco in the tank to show the power loss from our 91 octane. Also are idle video's, cruising, and dyno pulls.

If you are interested in this package as a whole or some version of it please contact us for a quote. We realize some people already have headers and a cai so we can adjust accordingly just final hp number's might very slightly.

Was that for your C5 or the Prius? Doh!

Come out to the omega event and than the 1320 event the following weekend! Or just have us port your fast manifold. it makes more than an msd at that point.

I need to get the starter replaced, so maybe a trip to your shop is in order :)

Joe,

How the hell do I contact you? I apparently can't figure out the PM on here and tried send an email to Joe@cpr.com with no avail.

THANKS!!
