I've run the stock pcv system, and the pcv line open (tb blocked), and never seen much difference. Has anyone else picked up ET/MPH/HP from PCV mods?

 

Terry, do you still have that 375ci for sale?

 

I do! It's still at MMS unbuilt. If someone wants it I bet they can have it together in a week or so.

 

Terry I don't think anyone is going to see any real HP gains from the actual PCV mod itself. You will pick up power if you fix the PCV from puking oil into the intake causing knock, but other than that I don't see any real power gains to be seen by simply modding a PCV.

I can see changing crankcase pressure being more prone to hurt performace, but not show many gains..

With our current PCV mods you wont see any gains aside from the benefits of reducing knock and plug fouling from oil consumption through the intake like Damian stated.
You will increase HP if you can increase scavenging from the crankcase without sucking out all the oil in the process <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Good crankcase scavenging reduces oil roping and creates a vacuum in crankcase area.
Smokey Y did a lot of work in this area I believe.

A dry sump for our cars would be killer and probably give us a ton of HP and rpm capability.
