Crankcase Evac Pump
That remark was directed at wazoo64 situation and not meant to be taken any other way.
As someone who thinks they have so much more first hand knowledge than most on this board why don't you school those who need to be informed about such things as...Vac pumps on the street...Pro's and Cons
Lol. There is so much mis information on the internet it is sickening. That is what I meant by my comments.
This is my personal experience.
They say Oil pressure drops with a Vac Pump Pump at Idle and at WOT. I found out in my case it for sure is a Myth. I gained 8 PSI at Idle and dropped none at WOT. That is 5 in Vac at Idle and 20+ in Vac WOT.
I had a similar issue as Wazoo. Excessive crank case pressure. I tried all the stuff you guys are talking about. Welded breathers tubes on the valve covers, raised them up etc. 1 Breather, 2 Breathers and a PCV. None worked at all. Oil was entering the cylinders at high Rpm. Not good for Nitrous. I had a couple oil leaks but nothing major. After the Vac Pump install, I have No oil leaks what so ever.
I installed the VP 104 Vac Pump Kit from GZ. It was supposed to be a bolt on deal. Lol to that one. I had to modify the mandrel and mounting bracket and get a different cog belt after the mods.
As far as oil in the canister........ I have checked it a few times after LONG runs in my car to the tune of 2 tanks of fuel per cruise and nothing worth noting was in the canister. The last time I checked the canister I had burned 4 Tanks of fuel which is about 55 gallons. Maybe, and I am being generous, there was 1 Table spoon of oil in the canister when I un did the drain plug.
As far as power goes, for sure there was a noticeable difference in how the car runs. I will forever use a Vac pump from now on in every build. It makes that much of a difference in noticeable power increase.
The GZ set up has Baffled breathers and an adjustable bleed valve to fine tune how much vac you want. Very easy to adjust with 2 fingers.
As far as I am concerned there is NO Negative effects of running a Vac pump on the Street. Only positive results apply.
Mine is a 410 Stroker that I drive the snot out of everywhere " Not supposed to do that with a Stroker" Lol. Solid Roller .634 lift at the valve "YES on the Street" I also hit it with a 200 Hit of NOS. A 904 built by me that I am throwing at least 725HP through with a Pro Transbrake "Not supposed to do that either" it has not missed a beat.
That is my story.
