When I am going 70-75 mph I am about 2500 roughly. I looked on the kenne bell website and the boost starts a 2K so my question is what kind of boost will I be at going those speeds? I know the KB 2.1 has a flat torque/hp curve so I can assume that I will be at 9psi through out the whole rpm band?? the reaon I ask is because town driving I can keep the car under 2K to keep it out of boost to prolong the life of the s/c and my motor but at those speeds I would be worried that I will be running uneeded boost that will just wear out my motor. I googled and searched the forum for about 30 minutes and couldn't find anything. I may have not typed the right thing in the search so if anyone could help with any of these issues that would be fantastic.
