Okay I am working on a Crusader tunnel project, that is going from a Blown BBC to a Turbo LS. The Berk pump currently has a stainless AA, and I am sure this turbo LS is not gonna turn it well. I have done a ton of high horsepower 4cyl stuff in the past and the hardest part of the equation was getting the converter right. I'm not saying that a pump is exactly the same, but they do share similar loading characteristics. I am leaning toward a B/C cut with the thought that is will be loose enough to let the turbos light and then load it down properly. The motor should make about 800 on moderate boost, and will happily spin 6800-7000. I am not expert, and looking for advice. Thanks in advance...

From what I've heard/understand most pumps can't push very well past about 6000-6500, and you need to be making max torque around 5000-5500 for something with serious HP (800 is serious HP) ;D

This might help you decide what impeller to use. I would also suggest calling your local jet drive shop. If you don't have one you should try B1 Racing. http://www.b1racing.net/ (http://www.b1racing.net/)

I've talked to a couple shops, they recommend starting with an A and cutting it down. Looks like thats really the only way to go...
