Re: Vacuum Source For Turbo Cars

["Stragand, Dave" <dave.stragand@xxxx>]

Hi All,

You don't necessarily need special vacuum pumps for turbo or supercharged cars. While it's true that turbos/blowers can provide manifold pressures into the positive end of the scale, the engine's normal operating state still provides for more than enough vacuum. At idle, most turbo/blown cars will still run around 15 inHg -- plenty for brakes. If you're still having problems, check out the anti-reverse valve leading from the manifold to the vacuum canister in the pontoon. It should only "allow vacuum" one way. (If memory serves, it's black on one side, white on the other, and about the size of 5 or 6 half-dollar coins stacked together. You can also simply use a larger vacuum tank out of just about anything in a salvage yard. It's hidden deep in the pontoon anyway, so what it looks like doesn't matter.
