[QUOTE="JAJ, post: 15882693, member: 131874"] I couldn't agree more!!! And there you have it - the Whipple bypass is set to operate at zero manifold pressure (behind the throttle plate), which is the point where you're starting to make boost. I wondered if there was a difference between Whipple and TVS because the TVS is a positive displacement pump (it pumps a fixed volume of air every revolution, but it doesn't actually compress it on the way through the pump) and the Whipple is a twin-screw, and I believe that a twin-screw actually compresses the air as it moves it. Trying to make a twin-screw take air at the inlet, compress it and then release it into a vacuum is wasteful and potentially hard to make work properly. Not having the bypass close until you actually need compression makes sense. Good luck! [/QUOTE]
