electric vacuum pump
Has anyone had any dealing with a electric vacuum pump ?
When I had the motor in the turbo car built in the winter the rings and all the motor up for a vacuum pump. I had the pump and belt drive set real low but when I installed all the turbo stuff there is no room for the belt drive pump.

Re: electric vacuum pump
From what I've heard Don they can't move much air. Les Pippen used to have two of them on his Camaro when it was a Nitrous car. I don't know if they data logged back then and/or had an idea how well they worked.

Re: electric vacuum pump
Star machine makes one, but it's real pricey and I think it is more suited for motorcycles, I do not think it moves enough air for anything big.
I am not really sure what the question is, but I am pretty sure the answer is Big Block.
Re: electric vacuum pump
I have been told the one Star has costs $ 1700.
I am going to check it out myself.
Thanks John and ytnova.

Hey Don, Dwight Parker was running an electric pump off of a cadillac on his blown Poncho in his Firebird.

Re: electric vacuum pump
We bought a GM electric for our Top Dragster...I wouldn't waste my money on another one. My shop vac. pulls more vacuum. I'd use it but I don't have a 1/4 mile extension cord!!! Ended up buying one from MOROSO. JMO.

Re: electric vacuum pump
Would one of the ones for brakes work? Like the one SSBC sells?
Re: electric vacuum pump
I know Dwight has issues with a rear main leaking on occasion, when the vacuum pump was working, no more leaks.

Re: electric vacuum pump
A 12Vdc vacuum pump doesn't have near the CFM capacity to evacuate a crankcase - especially if it isn't NA (though it may help keep oil from blowing past the gaskets).
One of the manufacturers promised a high-flow electric model by SEMA last year, but it never materialized - guess it's still vaporware.
It's almost always possible to squeeze a mechanical pump in with a timing belt - though you probably have to fab your own pulleys & brackets (after matching them up with the pump curve on that engine's particular RPM range).
