boosting as making it go faster or boosting as it doesnt shut off on long hills? if the later go to a junkyard and get a vacuum resvior off a modern car and mount it under the A. think of it as a capacitor but for vacuum - stores energy untill its needed.
94-97 s10's have a nice softball sized one bolted to the underside of the hood with a single vacuum line running to it.
The ball type is what I was thinking just wanted to add something to make them work a little better, I know there is electric but they are pricey and still do not look that good. thanks fellas.
