What are some of you doing to evacuate the crank case pressure on a Blow Thru setup? This is a street car with up to 15PSI of boost. I have 2 stock style breathers in 1 in each valve cover, the valve covers still have the baffles in place. This is just not getting the job done.

Use 2 - 12 lines coming off the valve covers and run them into puke tanks. I would not use a vacuum pump on a supercharged or turbo engine . If by some chance you burn a hole in your piston you will pressurize your crankcase and the vacuum pump will suck up the oil and overflow the breather tank and dump the oil all under your tires.

Not getting the job done in what way?? You sure the rings aren't shot?
I have a pretty good leak from the front seal, new seal, new balancer, new cover. Did not leak until I installed the charger. The rings are new and were broke-in with brad-pen break in oil. Engine prob. has 150 miles on them before the charger was installed.

Every engine has some blow buy good rings or not, the more the boost the better chance of higher crankcase pressures, I would put an evac pump on it and free up some ponys along with decressing the chances of blowing seals, I got mine from GZ motor sports.

Is a vacuum pump a good idea for the street, I have the same prob. and asked a few companies and they did not recomend a vacuum pump for the street. Just asking.
