Correct me if I'm wrong? The way I look at it I want to switch to a liquid cooled kb setup. Lower temps with max of 18-20psi. And either way I go I'm gonna have to invest in supporting mods. So the big question is the KB worth the extra price, especially if I switched to a liquid cooled set up?
    It all sounds real simple, like all blower packages are the same dimensions. If a KB with the same capacity as a Whipple is shorter then the Whipple then it will be wider and taller. The Whipple will just fit between the fuel rails. A wider KB might interfer with the injectors. Every blower has its problems to mount up. If it was easy everyone in the club would be doing it. Anyway like Brian said it doesn't matter cuz they aren't really available and if you find a used one you have to have the fabrication skills to make it fit

    Remarkably the KB 2.4 is over 2" shorter than the whipple 2.3 but its only 1/4" wider and is 0.1" shorter that the Whipple. The claim is that because they use a billitt case they can package larger diameter rotors into the same size case. My grand plan was to use 80lb shorty injectors to clear up any issues with the width of the case....of course that means hand made fuel rails as well.

    Everything is doable in the long run. I take it you have come across a KB you can use for a project. I did a KB setup for a member in the club so I know it can work. I beleive the Whipple works just as well and length is not that big a problem. Still in the long run KBs are not available in anything but used condition so for the rank and file its a mute issue

    Well, the swept volume of the rotors should increase exponentially with radius, but only linearly with length. So that explains some of the packaging.

    Yikes. Well, that explains the need for a bigger blower then. I am guessing that your motor must be breathing pretty well, making that blower really work for its PSI.
    God bless!!!

    I don't think a reasonably priced KB is in my future. Bare head units are not to be readily found and to purchase an entire kit then scrap everything but the blower is crazy and that's assuming you can find a kit with the right drive length.

    If this happens I think my only option will be Whipple.

    Corey,

    No worries, John Loudorf topped that number at the 2012 Shootout. I'm also planning to beat his 504 rwhp within the next month or two.

    No fancy liquid cooling is needed on an "AR/KB" setup making 20+psi, that is simply dealt with using large air to air IC or methanol injection.

    After hearing John was not using any race fuel on the dyno or the track, I think I know what happened. That said, I'd still like some confirmation on what happened, mainly to avoid it myself.

    It didn't go boom, it developed a knock and he quit to avoid further damage. I suspect rpm and oil supply had something to do with it. Casey can relate to that.

    His car made 500rwhp like it was it's job. On pump gas. If it had a bigger blower, it would have made more.
