[JoshK]

dammit stop it already. Now I am REALLY pissed i didn't just get the precision billet right away! Oh well, that is some awesome info to share man, thanks.

Just sharing the results lol.

Trust me when i say you feel this in the seat of the pants!!

The billet turbo was night and day difference!

And for those asking about spool difference and boost curves. Here are 12psi runs, ebc duty cycle unchanged.
Blue line is cast 67mm with .96 ar
Green line is cast 67mm with .81 ar
Red line is billet 67mm with .68 ar

good to see the layover chart!

Heck yeah! Just figured out how to display torque too.

At 14psi at 4,000 rpms the billet is up 100rwhp/100rwtq!

That's just a ridiculous difference!

So nuts... Mine as well save up and do it all right the first time!

Jeremy...if I understand correctly, the
CT4-6065 - 680 HP
CT4-6262 - 710 HP

would only spool up 2-300 RPM quicker than the CT4-6765?

Edit: Contacted COMP direct and they said CT4-6765 was the best one based on my current setup and Lunati turbo cams and CR.

LOL, yes I concur with the billet 6765 like I mentioned. Thats why we use it standard in our kit.

You put out good tech Jeremy, but I always come at something from multiple directions. I've found it cuts down on heartburn.

Always good to cover your bases.
