my vortech car ET'ed and MPH'ed the same pass after pass with minimal cool down and no intercooler (on a 2V car 10 years ago). thats centrifugal efficiency.
so if the A/W is so much more efficient, then why do all the factory PD blower cars heat soak so much? the water is still circulating. but once the water heats up, then it can't absorb anymore heat. its the same as the A/A car sitting there with no air flowing over it. I watched a Cadillac CTS-V lose .4 and 7 mph due to heat soak on his 2nd pass. The car was down on power the whole time we were at the track due to heat soak. We all know this...terminators, lightnings, ZL1, etc.
The centrifugals are the more efficient blowers, and while the twin screws are more efficient than the roots and TVS blowers, they still generate more heat per lb of boost. it's always been that way.
