pcv and thermostats for street strip cars ?

I use low tension oil rings in my engines to reduce drag and make more horsepower, there's a lot there, and if I don't use a pan evac there is too much crankcase pressure and it pushes oil out the front seal at about 7000 rpm. I used the pan evac system when my car was a street car too, I used a 3 inch exhaust system with 2 chamber Flow Masters. The trick is to use the factory type aspirator valves as the tension to open the reed valves is lower than with the Moroso units. I also used a pie cut on the draft tube to increase the vacuum pull.

It shouldn't suck any oil out of the motor as the actual vacuum is fairly low so don't worry about it coating your exhaust, I've never had any problem.

As for the thermostat and bypass, If you run a thermostat you'll need the bypass hose. If you don't run a t-stat just gut an old one and use the orifice as a restricter. This is what I did. I'm also a big fan of electric fans though it might require you to purchase a couple before you figure out how much or how many you'll need to keep it cool in traffic.
