At the moment, there are no plans for anything larger than the 2.3L that is already available. With a 10 rib set-up, you can get a pulley set-up to make 20 psi with the 2.3L which is good for over 600 rwhp on pump gas. Hope that helps, let us know if you have any other questions.
That is what I'm saying. I can achieve that with my current Saleen blower. I want a BIG blower for high boost. The only choice is KB 2.8 Mammoth. Too bad for whipple. I wish they would wake up.
