A negative pressure, pan evac system is the best on racers.
The header evac system is better than the pcv but there is a new kid on the block. The new system is a crankcase evac pump. It bolts on the front of the motor and runs off a pulley. It actually sucks the pressure out of the crank case. This alleviates the ring blow by pressure that acts on the bottom of the piston and increases HP over the header evac system.

RJL O.K. so how do I find the correct PCV for my engine which makes about 6 inches of vac at idle.Is there a formula for this or do I run a stock one.

spinn on a proper running car there is no con to running a pcv. they get rid of building crankcase pressure. its not like it will ruin your intake charge. its the EGR you dont like, the PCV is your freind

BOBCRMAN@aol.com PCV's are required by law on street cars. Dual breathers are ok on race cars. A negative pressure, pan evac system is the best on racers.

camaroman7d I think this was covered not too long ago. Might have been a different site.

In either case, you should run a PCV on a street car. Dual breathers tend to make quite a mess. There really are no cons to running a PCV (IMO). You need to get rid of that crank case pressure and on the street a PCV is the easiest and best way.

PCV or not

What are the pros and cons on running a PCV as opposed to dual breathers and no PCV?
