I figured out that the problem with my engine was that theres a huge vacuum leak, so its time for a new booster in my 67

i only have about 14 inches of vacuum of a good day
so i am looking for a booster that will work well with lower vacuum, if there are any that would give more assist without being any larger in diameter
i dont really care if i get a stock booster, i am thinking maybe i should be a dual diaphragm

does anyone have any suggestions?
thanks
Jon

Hydroboost do a search here on TC this is the way to go I believe.

well i dont really want to go hydra boost
im just looking for a better vacuum booster, i would think 14" would be enough vacuum

come on guys some here has a better booster
please help

so what should i do get?
what vacuum booster should i get that would give assist with slightly lower vacuum

or if i cant get one that would give more boost i guess a smaller diameter would also work for me
