Hey everyone, Im new to this site and have a 2003 Cobra. The car has the Boss 5.0 Block, JE pistons, Full stroker kit, Stage 3 heads and XE stage 3 cams and ect... It currently has the Kenne Bell 2.8H on it now that I will be selling for a Whipple due to wanting a little more. Iv been looking at the 3.4 Crusher and the new 4.0 Crusher. I was seeing if anyone had information on the 4.0 kit. Would this blower be too much for my engine? I do not drag the car so it is mostly a street and show car but yet again do want to get my numbers higher. Im at 705rwhp on 93 and street tune right now. Id be running 18 to 22 pounds with possible meth injection. Which is a better choice between the 3.4 or the 4.0? Thanks.
