Ive been researching around on different methods to scavenge the oil vapors and pressure from the crankcase and ditch the PCV system and came across someone that was using a 96 cobra electric vacuum pump in conjunction with a catch can and I was intrigued by it. I was wondering if anyone has any experience with it with a N/A setup as ive seen that alot of people are using it for boosted applications, or even any experience at all.
Thanks in advance.

if you are interested in it I can post up links later once I get back from work

Hmm...interesting...

I have tossed the idea around a few times but haven't really done any research on it yet. From what I have gathered 4th gen camaros have an electric pump that will work great for it.

yeah, ive been seeing that as well as S10 and Caddy pumps. But what ive been seeing alot of people are using the 96 Cobra pump as it pulls more then all the rest. Ill post up the links that ive found on what is needed. There are a handful of people that are using it and they say that it is a flawless system that works great whether full-out race or DD.

We can do that.... Even if it barely works it will help.

thats what i was thinking... as long as it pulls into the catch can, even if a little, it still has to be, by far, better then having hot oil/gas entering into your intake and manifold. Im thinking that it can work but I just havent seen anything for N/A setups. Ive read that people are using it but I dont know if they are using the same componets or what. I know that for boosted apps people are using a Hobbs switch set at like 2psi to start the motor up via relay and start sucking, but what should we do in a N/A setup? any thoughts?

I don't see why it can't run the whole time. It would be nice if we could get it to actually apply a vacuum to the crankcase.

[wraitherx]

hmmm... sounds like we might be doing alot of tinkering around with this thing You dont think that we can?

[wraitherx]

we can talk about this more here in about an hour... im leaving work now... finally

well the best thing to do is to hit up a junk yard and grab 1 of every pump we can think of. They shouldn't cost much. Then hook them up to some type of container with a bleeder and a vacuum gauge. Then choose the one that will pull the most vacuum.

Then all we have to do is hook it up. It may be a good idea to build an accumulator large enough to catch all of the oil. We can do that with used AC parts.

In the end there should be less parasitic loss because of the lack of pressure in the crankcase. Also the motor should be less prone to detonation. Burning oil, even vapor will cause detonation.

Thats what I kept on thinking everytime i ran the set up through my head. I cant see it hurting at all. That sounds good to me. we can make a day of it. Ive got a buddy that works at U Wrench It but we can troll others as well. We can get the parts, come back to my place (or yours), and get at it. Sounds like new project in the works here. Here is what ive found so far and for those that are interested.
this guy has it on his Tbird 331

I think im also gonna get her dynoed before and after to see if there are any HP gains and im gonna log her to see if there is a difference noticed anywhere.

from what it looks like in the fourth picture is that the guy has the Valve covers directly going into the pump and then the pump (im guessing output) feeding into the enclosed catch can (accumalator)

or....

the valve covers T'd off into the 1 of 2 ports in catch can (im sure its baffled), catch can to inlet on pump, then outlet going back into intake

seems like the best one to go with came on the 96-98 cobras. F6ZE-9A486-DC

[wraitherx]

yeah, thats what the concensus seems to be. Im sure that we can find some over at Johnson's and I think that JP knows someone that works there.

I tried pulling up that part number and came up with nothing. But i did find it at Rockauto. Id much rather get a used one for cheap to test until we can get the system finalized so that we dont ruin a brand new pump.

[Cricket]

I don't know anyone who works there, but I have someone I can talk to that might be able to help...also Johnsons isn't far from my house at all.

[wraitherx]

sounds good to me. Whatever they can do. So when do you guys want to get together and tackle this thing?

[C MY 4D]

I'm not sure, I'm slammed with sidework right now and am going to DC next weekend.

[wraitherx]

well, im pretty much in the same boat as well. Im usually free on weekends so the next time you get a free weekend and feel up to it just let me know.

[nutnbutcustm]

did you guys ever do anything with this idea? im interested in possibly doin the same thing to the termi? also if it worked how about a how-to?
