BTW, nice recycled ****

They are also good for motors with worn out rings.
Racers have been using vac pumps for years.
I just couldn't find it within my means to buy a 500+ dollar kit.

this will reduce blow by, probably all the way on a motor up to 400hp or so.. but so would a cheaper and simpler catch can... on a big hp motor 700hp + it wouldnt stand a chance...

Vac in the crank case keeps the rings in the walls.
Thats why when you break in a motor you do high vac pulls.
BTW as for the cheaper comment you could go to the junk yard and buy a used pump for 15 bucks and run it to a on off switch. Then just turn it on when your going to do a run.

Correct, Catch cans do not make vacuum, but either does your vacuum pump on a high boost, big tolerance motor.
Yes Vac in the crank case is good... just not acheavable on a 700+hp motor like we've mentioned. your idea is great for 95%+ of the cars on here... as long as the pump doesnt pull too much vacuum...
cheaper, not really... either can be made very cheap or very expensive... one has no moving parts or wiring though.. .and I like that.

Re: ---- YO CATCHCAN NWS (o)(o)
After reading more im defiantly going to put another PCV between the pump and the first PCV.
I read that the PCV controls the amount of vac you can pull from the crank case. So it needs to be there.

saturn cars have smog pumps that work well and are abundant also.
whoever said only sloppy motors will benefit from this has no idea what they are talking about. EVERY boosted motor, even the best built have plenty of blowby that can benefit from this, especially high boost motors.
