I'd be interested to know what people are getting out of the AIR pumps. Actual readings not a guess, but I'd bet money you can't get more than 1-2". Thats not going to do anything except evac the crank case. Might as well just throw a breather on there for all that trouble. 10"+ is where you will see a power gain and finally seat rings.

 

what is a good rate to have these? is a 30 to much?

 

I have an AIR pump off a C5 vette if anyone is interested. PM me.

About 40 bucks to your door to cover shipping and paypal fees.
