[QUOTE="fullboogie, post: 15954900, member: 23633"] Porsche, don't overlook the hp needed to drive the blowers. Kenne Bell has a few really good articles about this topic and if I recall, the numbers are quite significant. All this boils down to net hp, so you have to take into account hp losses to drive a small blower at 15 psi vs. hp losses to drive big blower at 15 psi, right? Seems that a larger blower that doesn't work as hard to achieve the 15 psi takes less hp to drive, which may be the difference you are looking for. Just an idea. I'm no engineer, just going on what *might* make sense. Isn't this the same reason the TF and Alcohol guys switched to the high helix twin screws years ago? Same psi, less hp to drive the blower, so more net hp. [/QUOTE]
