[QUOTE="Justin@VMP, post: 14239591, member: 18468"] It was stated at one point that the blower should be slowed down for better track performance, to put it more in the efficiency range. I disagree with that. Every compressor is more efficient at lower RPM/boost, but moving more air is the name of the game when it comes to making HP. The TVS is actually more volumetrically efficient than a twin screw of the same displacement, I had the original TVS put on an SAE flow stand years ago. The slight hit you take in thermal efficiency is mitigated by the intercooler. This is evident by what Ford did on the 13-14 GT500, that was the most boost out of the factory for any OE blower, ever, a 2.63 pulley, greater than 2:1 ratio. What did they do? throw a MUCH bigger heat exchanger under the front bumper, upgrade the intercooler pump, and slightly improve the HE under the blower. Now this car has to go WOT for several miles to reach 200 so this is part of why they did all of that, your average GT500 owner doesn't shoot for 200, he just wants more for 10-20 seconds at a time, and an upgraded front HE is enough for most peoples needs.
