I bought two of them off of E-bay for 20 bucks apiece. You just have to watch for them, they are always on there for 50 or 60. Here is one for 60 right now. Item number 360182675334 on E-bay.
I'll try to post up some pics of the installation next week. And again this is with a 16v battery not sure of the results we would get with a 12v system.
How much more hp will you get putting on a vac.pump?
I don't expect to pick up a single one. If we do great, but we are running it to keep the moisture out of the motor. If it will at least keep the motor in a neutral pressure situation we may pick up a few. This motor made 702hp on the dyno and seems to have a really good ring seal so who knows?

I'd be curious to know what type of vacuum, if any, you see at 7000-8000 RPM with it under full load.
Just make sure you don't get into a positive crankcase situation, or you may find out which seal is the weakest on the motor.
You might want to consider something like a roll over check valve in the valve cover. Something that will seal with vacuum, but vent with pressure. It'd be some cheap insurance to do that and not worry about pushing oil pan gaskets out and spraying the tires with oil.

Just food for thought.
WJ if we are pushing gaskets out we need to work on our ring package. :lol: :lol: .
