Hey guys just a quick question, My motor is currenty 9:1 c/r at the moment with 4X 10an breather pipes coming of the engine (2 on the valve cover and 2 off the block). I'm going to be turboing the motor in about a month or so's time.

What im wondering is could i be venting the engine to much as its NA at the moment ? Or am i just been paraniod ?

I cant see it been a problem but i would imagine you need some crankcase pressure ? ?

anyone ?

you dont need any crankcase pressure.........think about dry sump systems.......they create vacuum............youll be fine.

thats why they started the catch can deal, so they can get rid of pressure. at high RPMs crankcase pressure becomes crap
