pcv and thermostats for street strip cars ?

pan-e-vacs don't work well with the back pressure with cambered mufflers or a full exhaust system. Although as long as the pressure is higher in the crank case than in the exhaust it will flow to the exhaust, but that is not how it is designed to work. Ideally you want negative pressure in your crank case for better ring seal. Oil pressure won't effect how many breathers you need.
