Does anyone use an electric vacuum pump?

[75Dart440]

Does anyone use an electric vacuum pump to provide vacuum to the power booster? How well do they work? I heard it takes to long for them to rebuild the vacuum after coming to a stop. I ask because i have a 440 in my dart with a mopar purple shaft cam. it wont provide enough vacuum for the booster. I bought and installed an aftermarket 8" dual diaphram booster. its small because the original booster wouldnt fit with the 440. The manufacturer says it wont work without at least 18 inches of vacuum.

How did you correct this problem? I have a 74 Dart with 408 and same problem.

Do you have power steering? If so, might want to check into a hydro boost sytem. Pretty sure RMS sells a complete kit.....just checked and while it aint cheap it does not rely on vac. at all.....http://www.reillymotorsports.com/store/product.php?productid=16196&cat=273&page=1

Yes, I do in my Challenger that has too much cam to produce correct vacuum level for it's power brakes. I went with based upon an article in Mopar Muscle. It does work well, brakes feel good. Only draw back is sound of pump as it builds the vacuum...usually just at first start up of the day. A worthwhile trade off though.
