I have a kenne bell 1.5L 8psi and also a Powerdyne BD-11a. I have the Kenne Bell on the car now and have never ran the BD-11a. Just wondering on everyones thought of which they would run and why. I have never driven a centrifical type blower either is the main reason I'm asking. I love the twin screw. I have the motor all out right now and debating wether or not to try the BD-11a out or not or would i be disappointed or not. Thanks for all your inputs.
Not even knowing the year, or engine type that the blower is going on, I'd still have to say KB. Powerdynes just have too extensive a history of problems with the internal belts breaking for me to run one. That, and they're also pretty inefficient, so you're blowing some nice hot air into the engine anyway. If I had the choice of where my hot air was to come from, I'd go KB and at least made some nice power down low, too.
It's a 91 fox body coupe that has a FRPP shortblock, trick flow heads, F-cam , BBKlong tubes, ported stock lower intake for the kenne bell, trick flow intake for the BD-11a.
