Race Proven Motorsports 580rwhp 520Tq CAM ONLY!!
 

This is the car that made 570 cam only before and i wanted to test the LSXR on it. We made a baseline today and it made 568(its 92 degrees in the shop) We left it strapped to the dyno and swapped intakes and im happy with the results.

What's cam only mean Fran??? Just joking bro...

Nice #'s!!!!!

10.x rwhp 13.x rwtq !! That's some nice gains over the ls7 intake.

Was the ls7 intake ported or unported? Was the lsxR ported or unported?

Just to clarify the actual a-b comparison Thanks for posting !!

10.48 at 135....LS7 was ported LSXR was just cleaned up.

Video added.

Whats the cost of the manifold and the throttlebody? Or do you reuse the stock throttlebody?

We reused the stock ported TB for this test but we are in the process of making a drive by wire 104mm TB..

PM me if you are interested in an intake and i can get you some prices shipped to you.

Thanks for the clarification. Test consisted of Ported ls7 and cleaned up LSXr. Would you care to speculate what a complete Porting of the LSXr "courld/may" yield ??

Lots of people on here with 427's are looking for a very good reason to upgrade. You've posted some good preliminary inofo. Thanks again.
