Also - if Turbochargers were more efficient than superchargers, John Force would have them on his Top-Fuel Funny Car...
There are alot of turbos on drag cars and I remember back in the 80's and early 90s when they experimented with them on Top Fuel cars.. They worked well but at the end of the day it was the Wheezer that won..
Jim - At one point I was thinking of combining something along the line of a CVT with a supercharger to actually vary the percentage of overdrive depending on the signal from the ECU.. Are you guys playing with that yet?
??? turbos are more efficient then supercharges... The reason why they are not used in top-fuel is because turbos of that size need to spool up some how, and, they have a potential to create some pretty serious drama. Where a belt driven supercharger simply does not. I think it takes something like 2000hp just to DRIVE the supercharger on those cars as well... I think superchargers are more stable when the driver peddles the gas, too; since turbos don't produce a linear power ban by nature, i can only think of the manifold pressures with someone jumping on and off the gas with 6000hp on tap.
Have you ever seen those truck pulls where they have a semi-tractor pulling a weight transfer sled? Those things may have 6 HUGE turbos and they have to sit at the line and spool them up... sounds like an F-16 before take-off.
