Crankcase Vacuum pump

[strungout6]

Ive noticed a lot of threads about interest in this, however the only real answers were an electric smog pump or a stand alone independent pulley set up. I purchased a GZ sportsman pump and it bolted into the area where my A/C delete idler was located. With the 7.5 serpentine pulley from GZ, the catch can behind the front bumper, T.I.G fitting in the valve covers, it was as bolt on as I believe you can get with these cars. Works like a charm 12inhg vacuum. No more leaks either.

I would like more info about the unit and pictures if you have any?

That is great for a track car, but most owners like to have AC on the street which is why the electric pumps are used.

Do you use a bleed valve to control how much vacuum is pulled?

In my race car the belt-driven pump pulls about 12" of vacuum as well, thanks for the info.

I personally wouldn't have deleted the A/C, however the car already had it done. Ill get some pics tonight, I tried fabricating a standalone bracket for about 5 hrs before a had that moment of clarity and decided to pull the bracket and slide the pump on the studs. Saying I was "Shocked" at the fitment is an understatement.

And yes, I installed the bleed valve in the pass valve cover. My psi gauge is in the oil fill cap. In order to maintain a certain amount of "oily air flow" to lube the pump I wanted the bleed valve on the engine, opposite of the suction pick up.

For you guys interested. Here is the GZ pump install pics in the factory A/C location. I had to go 1in longer on the serpentine belt thats it. The factory idler works great. It pulls 12in of vacuum WOT. Worth every penny.
