vac pump

What would be the benefit of a vac.pump on a cam,head,and tune 04 goat?

that would depend on the size of cam. Unless you're going pretty damn large I wouldn't worry about a vac pump.

+1 Brakes are overrated.

unless you go with a huge overlap on the cam your brakes should be fine.

As you stated, if there is significant overlap then a vacuum pump may be necessary. The engine wouldn't have enough "suck" for vacuum operated accessories, such as the brake booster. Vacuum pumps may also be used in combination with low tension ring applications to alleviate blow by and help the pistons seal to the bores better. The low tension rings create less friction, less heat, and free up horsepower. I always wondered though if the gain would be offset by what it takes to run the pump, assuming it is mechanically driven.

Bunch of pump homo's....hush your mouths....
Screw a pump man...lets go back in time

We used to put what we called "full race cams" in our engines back in the day....had no vacuum for shit .....
So we put vacuum reserve cans on our rides

Guess what...I still do.....always have 12-18lbs of vacuum in reserve for the brakes....
Cheap and works very well.... http://www.jegs.com/c/Engines-Compon...11491/10002/-1
I put mine where the battery used to be along with the electrical connections.....I went ahead and put a gauge on it just to watch for any leaks....

Vent your crank properly to get rings to seat....

so are you people agreeing with me or dis-agreeing with me??? Hell, I can't tell anymore. It's just all a bunch of rambling to me.

Back in the old days EVERYTHING ran off of vacuum for the most part. These days it's mostly electrical so if you have enough vac. for brakes then you're good to go.

**pajeff02** · 06-17-2009, 12:17 PM

I agree with you.

You have a little BBQ Brisket stuck between your teeth...right there....
I am saying the boy doesn't need some damn vacuum pump....just the canister if he is running a monster cam.
