ok guys, I have been around racing for about 12 years and here is a dumb question I have always been curious about. some guys run a vacuum line to the brake booster and the tranny and others don't. I guess I always have ran them and haven't had a problem. I'm sure some others out there know a lot more about it than I do. any input?

i thought when you did something like running vacuum took away horse power, so i have never used vacuum.

that's what i was wondering. does it bother the tranny not to have the vacuum? i just run in 2nd gear all the time anyway.

I dont know of anyone who runs the vacuum on the transmission, but do know some guys that run it on the brake booster simply because we see how long it takes the guys who arent running it to actually stop...not sure if thats the reason their brakes arent good or not though.

u dont need the vacume to the tranny all it does is to allow the tranny to kickdown to another gear like passing gear and the one to the brake booster has to be there to have power brakes as far as taking away horsepower i dont think so

If you take the booster and drill a hole through the baffles on the inside. You will have a very good feel of what the brakes are doing. I always disconnect the vaccum and drill and I do not have a problem stopping. You will get a mushy feeling if you do not drill out the booster baffles.
