I wonder if a turbo gives less wheel spin than a s/c, because of the lag and boost buildup.
I guess it depends on the peak torque.
think your best be is gonna be a whipple screw type of charger really. the rotor types are gonna generate too much heat. once you spin them fast enough to over come their losses.
not gonna be a hell of a lot bigger than an alternator, have less losses and easier to put an intercoler/charger into the line with

Generally no, if there is no electronic boost control, the supercharger will always build almost linear. The turbo will not, it will reach it's peak a lot earlier and maintain until the flow limit is reached, or the rev range finishes. So you end up with a point in the power curve where the rate of change of torque is massive, hence wheel spin at that point.Originally Posted by Andy K
Removing the ECU control of boost for my MR2 enabled me to feel the difference that limiting the boost to revs makes. Without the ECU being able to control it, and relying on the actuator and another bleed device to 'control' the boost means that I get a kick in the back from the torque surge, however, if I put my foot to the floor in say third, the wheels don't spin until this torque surge ocurrs, then it's off the throttle a bit to get traction back. A supercharger would have a more limited boost, increasing with revs.
Of course, there are different ways of doing both turbo and supercharger systems, and controlling their boost curves. So it would vary system to system in my book.
