    Boost limits?

    What are we limited to as far as boost pressure and the the RR ecu with stock injectors? I'm suprised that no one has come out with a gear set to spin the SC faster. Then again i also think there could be a reason for that. I imagine the SC clutch could only handle so many rpms or would become very unreliable.

    That is exactly what the problem is.

    As big as the stock intake manifold is i think you could easily toss it and fit a nice roots style blower in there with a decent intercooler. Then just make up a pulley system for the belt. I don't know how a roots style blower will react to the ever changing rpms but i'm sure a small roots blower will work .

    you really want a Screw blower, not a old Roots deal

    i worked with art Whipple in "92" using these before the Whipple charger, not legal in fuel racing, but in alcohol classes Pat Austin did quite well with the autorotor screw compressors.

    I use one on my fuel bike. at the Hit i make 43 psi with 90% nitromethene,... with this blower

    Damn Nitro thats pretty serious. I don't think we need anything that big but yes a screw type positive displacement blower would be more effective in a smaller package. By the way welcome to the forum!

    I guess so with that thing! I wonder how long it is before someone tries to strap a positive displacement blower on a 4 tec?
