hi there....I have been using the car with unboosted brakes, but have now put the booster back in. am running vortech v2 on 360 sb. what I need to know is what affect if any will boost have on the affective operation of the power brakes. will it be necessary to put a non return valve of some sort between the power booster and the manifold.

cheers
 
"boost and power brakes"

What means this?

The engine is boosted? IE turbocharged? Supercharged

If so, you HAVE no vacuum

But if you have simply installed a booster on a naturally aspirated engine, then yes, you need a check valve. This was originally part of the fitting which went right in the grommet in the booster
 
ok, so that fitting at the grommet on the brake booster where the hose to the manifold attaches, is a check valve then ?

well....kinda feel a bit stupid now. just went out to the garage and had a look at THAT fitting, and well, it is a check valve. thought it was just a plastic elbow. never really looked at it before.:mumum:

any who ....merry xmas and all the mopar best for the new year
 
Yer welcome. Make sure you examine it and that it actually works. Some of this stuff is getting old, LOL

Why can't you have vacuum???
With a turbo it is not always under boost conditions. Same with a procharger.
The boost needs to be built, it is not always there.

Sorry but you are 100% wrong..

The engine is in vaccum under part throttle and idling situations.. so that being said the power brakes will see vaccum when you take your foot off the throttle and hit the brakes.. because the boost is now gone out the blow off valve..
 
Many vehicle equipped with turbos from the factory have electric vacuum pumps on them to provide adequate vacuum for the brakes when needed. A power braking system needs to have enough vacuum stored in reserve for a panick stop situation & turbocharged or supercharged cars may not provide enough vacuum (in certain circumstances) to replenish the vacuum reserve in the booster quickly if needed.
Just saying.
