What kind of power can these make. Whipple claims 800hp. I assume thats flywheel. Is the Kenne Bell 2.6 a better choice? Looking to make 550hp at the wheels on pump gas. I have a JDM built motor, built trans, 60lb injectors, and twin walboro 255's. I know this is a big debate, but just need some more insight on making the right decision. I have had good luck with Whipple in the past. Just a weekend cruiser. Also, where is the best place to buy one? Any help is appreciated.
