Is there a point in which crankcase pressure becomes an issue? Or is it that most of us will never hit that HP level. At 500rwhp would it be a concern? Thanks, Rick.

 

I run the stock PCV system at the 800 flywheel HP level with no problems.

 

I think bore quality is the real issue here. If they are not straight anfd true they wont seal and crankcase pressure could rise badly at low power levels.

 

I am running over 750FWHP and over 800FWTQ on Juice. I hit mine with about 285FWHP out of the hole. I have never had any luck with the stock PCV system. Alway dumping oil in my intake since the day I bought the car.

With no vacuum on the Crank case Mine make a little pressure in the bottom end. time to add a vacuum pump
