How much will Vacuum Pump help?

RussellinNC · 09-01-2010, 09:01 PM

If you put one on a car currently running a crank case evacuation system from valve covers to headers and change it to a nice vacuum pump system (no piston ring changes) what gains are normally seen in ET and horsepower?

If you need some of my engine and car info let me know.

Thanks

700 hp 383 18hp @ 10 psi on dyno about .03 on the track must have in my opinion for this motor. just make sure you engine is sealed pretty well or you will suck out a ton of oil.

On my 550 hp 406 it gave me 12 hp on the dyno and stoped that little front seal oil leak I had on my belt drive
