Was wondering what the best way the Vent the crankcase on a boosted motor? Would welding a NPT bung to each valve cover and then hooking some A.N. Line to a breather tank work? So each side would have it's own tank. I attached an example.

With a Boosted motor what is the most efficient way to releave crankcase pressures. Is the OEM design PCV system efficent enough for 8,9,1000+ HP?
I had a discussion with my step dad about welding a 3/4" bung into each valve cover and then routing each side with- 12 line to their own breather tanks. He said that wouldn't be enough. You'd need 2 bungs per side and a total of 4 -12 lines to 4 breather tanks to be efficent. I think that is way overkill and a big waste of resources. If thats the case might as well use a vacum pump. What should I do?
I really need an answer there are plenty people on this board making those kind of power numbers soooo what are you doing?
Anybody??? I read all the posts about stangs with sick amounts of power, so what are you doing???
I would use a Vaccuum pump at higher HP levels 600+. There are many electric pumps available now so the nonesense of making brackets is gone.
I think a -12 from each valve cover to a Y then into the vaccuum pump and vent it into a catch can with a breather would be sufficient. I have seen set ups like that before that work quite well.
Chuck thanks for the reply. Electric vacum pump? Do you have any recommendations?
if routing the valve cover hoses to the airfilter is going to be a problem becouse of the maf sensor getting cloged with oil drips, then why not route them to the exhaust in an angle just like the race cars have ?
I am running a speed density system. As far as the exhaust vacum is concerned, it is my understanding that those types of systems require constant high rpm to maintain any sort of vacum. not really ideal in a street car application.
Ok, thanksQuote:

gzmotorsports.com should be able to take care of you. Many people on hardcore50.com are using them. You can mount the pumps in the stock location of your smog pump.
