Greenlight and I were having a conversation about that a while ago but I can't find the post anywhere. He was the one that knew more of the specs that should be used in a pump and said he even had an extra one sitting around. I would try to message him and see if he'll comment help you out.

Maybe this is something?

I guess you could make a custom bracket & pulley and run the vacuum pump at the airco compressor position?

A vacuum pump is the best way to go, but if you are only worried about dripping oil on the track and in the engine bay, just add a Jaz breather catch can. On my current engine project I'll be running one of those off the front KV. Here's a picture of the setup:

yes I have a catch can I'm gonna install. but having vacuum all the time in the krank case has its benefits too. I had assumed the kv's kept enuf vacuum in the crank case that it would say in neg pressure between corners.

The problem is you are running full throttle until you hit a corner, so there is no vacuum to sustain.

krazik

yes I understand. thats why I was looking for more info about the pumps. Only ones I can find are big and belt driven which I don't want.

i thought your front line was running into the intake manifold, forgot you said it vented into the air.

Make sure the clean ones blow and the dirty ones suck.
I'll PM you a diagram so there is no evidence.
