Electric vacuum pump

Electric vacuum pumps that come out of factory vehicles, are they good to use on drag race 580ci 14:1cr?
Thanks

no....they wont pull enough.

OK, thanks!

they work fine for removing moisture, but thats about it. They will provide about 4-5 " and thats about it.

About how much is needed?
Thanks

Whats the application?

Wet Sump...... About 10-12 no more or you'll have issues with oiling.
Dry sump and special parts and coatings....... a bunch more.

580ci 14:1, wet sump, low tention ring set.

The only electric vacuum pumps that I know about which have the power to pull enough vacuum in the crankcase are the ones that are used on Pro Stock cars. They are special built and around $2,000.00 to get one.

Need to keep it at about 10-12# much more and you'll have oil pressure and wear problems from no oil splash.

What about the evac system that uses the check valve in the collector? About how much they will pull or it will depend on a number of things?

less than the smog pump deal

Are you talking about the electric smog pump from a vehicle?

yes, not the 2000 dollar prostock deal

The crank case evac system that im using is for sure pulling moisture but im not totally sure about vac.
What about the COMP electric pump that suppose to pull 12,15 or 20''? I think it has a regulator.
Thanks

What about two of the cheaper electric pumps hooked up, One to each valve cover? Should get about 10'', u think?

The one I use on my car keeps it from pushing oil past the gaskets, when I use nitrous. I know it's not ideal for horse power, but it works for what I intended.

Hey Chuck, that pump gotta b pulling some vac then. Where can I get one from? You are talking about electric, aren't ya?
Thanks
