What are the advantages (if any) and disadvantages of removing the vaccum booster in a hot rod? I want to run a turbo and this poses a problem with vaccum available to the booster.

should I run a smaller diameter main cylinder to increase pressure at the wheels?

or increase the leverage ratio of the pedal???

please guide me.

I don't think you have to be concerned about the vacuum supply as when you are at full throttle you won't be trying to stop and when you are trying to stop you won't be on the gas. If I remember correctly there is enough vacuum stored in the unit to allow you to stop with a dead engine. Be sure that there is a good one way valve in the canister.

he's right you still can run power brakes with a boosted engine look at all the imports that run around with turbos on them they still run vacuum boosted brakes. Like Walt said make sure you have a good check valve in the booster

Yes I know that, I already have a B&M supercharged Elcamino that keeps the booster, but I use a vaccum reservoir, I wonder why some people remove it, and how does it perform?

thanks

Lots of American cars & trucks came from the factory without power brakes, even the ones with disc-brakes. You just have to push the pedal harder. I feel like I have better feel and better control of the brakes with the manual setup.

Jim,

is it necesary to increase the lever ratio of the pedal when converting to manual? or just a pushrod adjustment is all that's needed.

Thanks.
