    It just depends on what you want? Drag racing? just fun?

    Personally I like the Roots best due to the instant throttle response, no waiting for boost to build up...for my street driving it is more fun and I will never be on the 1/4 mile track where the Centrifugal might have the top end advantage. Kinda depends on what you want to do with it...Kenne Bell Twin Screw for the win!

    For tooling around the city I love having the roots blower.

    Instant boost = instant smile. ;)

    I really does depend on how you will use the car .. what are your expectations?
    Obviously, either will give you a grin. I always suggest getting a ride in both to decide.

    once you try out a KB, all centrifugals (and other roots for that matter) will feel to you what they really are - little kid Lego's.

    Haha - very good.

    I don't think I'm as young as most people on this site - but I guess that one slipped by me. ;)

    Skippy would be an older term, not a newer one.

    I have had several cars with centrifugal blowers- have a '97 Cobra with an '03 kind of build now and there is nothing like it. The car has 512ft/lbs torque at only 2900 rpms and it feels like someone is slamming you in the back with a sledgehammer coming out of the hole-

    This is the most fun car I have had in a really long time-

    Meh, you don't need no stinking blower to do that, you just need real displacement and good crank stroke.

    My old 418 made 442 ft. lbs. at 2800 rpms at zero psi. :)

    Long live pushrods. :ass3:

    I think that making 70 more ft/lbs of torque (about 15% more than 442) from 284 cubic inches as opposed to 418... kind of speaks for the fun you can have with a roots blower. With that said- strokers and big blocks are awesome to begin with and certainly kick that much more tail when some atmosphere are pushed through them-

    418 cubes and it STILL fell short of a motor with 134 LESS cubes ........hmmmm wonder why Ford went to modular blown power. Pushrods are great motors and the bigger the better, but the modulars have their place on the performance front too. Some people are old school and others like the newer technology of performance. Cant we all just " get along" :angel:

    It must suck to need boost to make power. :ass3: :eek:utofcloset:

    My motor at equivalent boost levels would annhilate the anemic 03 Cobra with its tiny bores, small displacement, and wimpy stroke.

    Carry on.
