Thanks for the rapid response....
I am between a 6768 DBB and a Billet HP4271RL.
The PT Billet 6765 in the Supra world is making from 800 to 850 WHP on a manual 6 speed equip car on E85 and gas application between 30 and 35 PSI of boost.
My transmission is a big 4L80E and I need 750 WHP...
Patrick a few question for you sir ....
To bad we don't have you in the Supra community to help us out with question on Precision turbo performance and specs.
I really enjoy all of your post here in turbobuick.
What is the difference in HP and spool between the Billet 71HPQ, Billet 71HPS...
