If the Wolf Whistle runs off vacuum then I am SOL because I am running a hyd. roller cam with so little vacuum that I can't even run a power booster for my brakes. I'm using hydraulic brakes. Guess maybe I will have to carry an air cannister inside my roadster to use as a horn like those hand held air horns people use at sporting events.
