Wow, that one looks nothing like the one that came on my TA and the one thats on the '01 SS looks the same as the one on my TA... Nothing like the above from what I can see of it on this car.

But in the pic you posted, it sure does look identical..

In that case, and since madman and brady arent responding much, I would guess you guys are right about the air pump deal. And it would be for a drag only car as I know the factory pieces arent designed to handle oil or run for extended periods of time.

I had one on my last car, it was definitely a "drag only" type application, in fact I burnt one up street driving with it. The electric pump seemed to work very well but I don't have any data to back it up. I'm going to run one on the new car and I'll be able to provide some crank case pressure readings as recorded by the Big Stuff 3.

When you get that data, please post up so we can see the results. How much street driving did you get out of it before it burnt up?

That is basically the same thing as the pumps on the LS1 cars. I know of a local racer that has one on his 408 small block dodge and it pulls around 3 inches of vacuum. I figure the belt driven pumps are better than this particular setup however the electric pump the pro stock guys are using pulls somewhere in the mid 20's.

You guys are going to measure how much vacuum to pull before just slapping a pump on there and calling it good correct?

Thats not an f-body pump that I showed, but it is infact a gm pump for a hell of alot thess than 350$

I figured out what pump that is off of and its definately not an f-body...its actually the preferred electric pump (based on what I've read) as it flows a fair amount of volume. Some report 5-6in of vacuum, which though not ideal, can definately keep oil control in check

Hey wicked, do u know what make and model they are using to get 20 + with an electric. Hell, I would be in heaven to get 15 ish. If all these pumps are making is 3-6, I'm buying another Moroso.

I'll post results.

I basically got no street driving out of it, one race we went to (World Street Race), we had a 30+ mile drive, and when I got back the pump was locked up...

Nice, no little cruises with that pump! lol...

I wonder what pump the pro stock guys are using to pull that much vacuum and if they'd be reliable enough to include short cruises in a strip/street car?

i know this might be a weird question, but since it's electric, could you wire it in to a WOT switch so it's not burning up at normal driving?

Yes, It could be wire to a WOT switch.

Fire67

iTrader: (3)

But it would only benefit you when running WOT... Anytime your at less than WOT your building crankcase pressure by having the restriction of the non-running pump being the only place to vent the gasses.
The crankcase has to vent somewhere all the time


Plus with these things only capable of pulling 5-6" of vacuum, only running at WOT throttle you may never see that much vac. do to the higher rate of crankcase gasses being produced.

I honestly don't have any idea. I've just know some local guys that run Competition Eliminator run them via Kurt Johnsons or Steve Schmidts suggestion, one of the two. I believe its run off of its own seperate battery and they don't turn it on until they stage. I know the local guy has lost a motor once this last year from lack of oil to the wrist pin. With that much vacuum you've gotta have the casidium(sp?) coated pins and the pin oiling through the rod otherwise they'll seize and break in a hurry. We just had a 3 vane moroso on our old single dominator 468 that made 856hp 644tq and it would pull around 12-14inches wound up w/o a pop off valve. I bet the 4 vane would pull enough to need a pop off valve.

I bet the PS guys are running something like this:

WOW! thats expensive! For that kinda price, Id rather run one off a pulley

That one's 24V, so it would need its own battery... The one with the kit is probably one of the drill batteries Ive heard of these guys using.

Amazing the money people spend on this stuff... It seems like it would almost be cheaper to get a pulley drive vac pump, mount it remotely and drive it with a 12V electric motor of sorts.

WickEdSix98

iTrader: (4)

I bet that is the pump they're running, seems like I remember someone mentioning them being 24v pumps.

BTW, pro stock is not a budget racers game, money should be no object and even then don't expect to be competitive.

mrdragster1970

I know I'm not switching to 24V. So that takes care of that. I had about 15ish with my belt drive, and I actually took off the valve for a vent system a few years ago and never had a problem. Some Comp Elim guys spend as much as Pro-Stock, so I would bet they have some pretty trick stuff. Thanks for trying everyone.

Fire67

iTrader: (3)

They run them off a seperate battery... Actually a battery for a drill. They have them charging between runs (multiple batteries) and switch them out before each run.

Too bad this stuff is so expensive, as with the procharger, I really have no way of running a belt drive, unless I got someone to cut a cog pulley into my Procharger pulley spacer.

I've been told by many guys over the years that running a crank case vacuum pump will add horsepower to any engine. Something about helping to keep the piston rings seated.

Now, I'm no expert here so I'm trying to learn.

How would one go about installing an electric pump on a daily driver?

I doubt any of the electric pumps discussed here would last very long for continuous duty.

Although I'm sure this won't work, what do you guys think about the SSBC 28146?
