I've heard you get about a 25-35hp gain from a vacuum pump.

Theoretically this is true IF the motor was designed for it, OR is lacking and the pump can make up for this. IF engine has a smaller cam, you can create the vacuum as need there, therefore the Vac pump will do nothing really. AND too much vacuum can/will scavenge oil off rotating parts therefore loosing the film layer. NOT GOOD.

Buddy just built an LS 6.0 with small hyd roller. Made 585 Hp with 16 lbs of vac. So on this the vac pump might have cost Hp for the drive. Most I hear from want vac in the 18-22 lbs range AT RPM

Running a vacuum pump is up to the guy owning the car. It;s a fact, keeping the crankcase in a vaccum. Will make the motor work eazier and keeps the oil from foaming in the pan. You can;t have too much vaccum, you will pull the oil off the rods and pins. I was told to only run 12 inches at full RPM. All I can say is i gained a whole 1/10 of a second and 3 plus MPH.

Ha......that would be fun running next to Benny.....well for only a short distance until he kicks in the secondary's.

[Salvatore]

No, no......... weight per cubic inch. You will get a couple lites on him.
Better not miss a shift though.
