But what I dont understand is why high RPMs would require a catch can? Street, track or off road use shouldnt (unless I am missing something) need it?.?. I agree with you, the only time I see an issue is when I am running along the freeway or desert (off road car) at over 6,000 RPMs for prolonged times. So your are right when it happens, I just dont know that I fully understand why. Once I understand why it happens I can start to formulate a way around it. Could it be that we need bigger oil tanks (30 quarts?) so there is more than enough room to separate air from oil? Is it that we need better oil pumps in the engine to ensure no oil is in the engine ever to be swirld around (vaporized) by the crank and rods?

Just interesting. If you had a race car, how would you solve the issue so it never needed a catch can? = )

Thanks for your views.
