Re: solution to power brakes for engines with "lumpy" cams

Will be interesting to see if it works. I guess it will depend on how much the booster volume decreases the vacuum when brakes are applied.

Dave, an AC vacuum pump needs to pull 29" vacuum to boil moisture at temperatures less than 80 degrees F, so they typically cost more. The really good (and expensive) ones will approach or exceed 29.9".
