Power Brakes on a FI engine

What's the best way to get powerbrakes to work on a turbo car?

With no vac. how do they work?

I know GNs use an electric motor, I'm looing for something simpler.

Should I modify a vacum pump?

Thanks,

JK

They work by taking your foot off the gas before you try to brake...thus reestablishing vacuum.

What about when I'm trying to balance the car in a corner while trying to keep the boost up?

Try installing an aftermarket vacuum reserve canister, jegs and summit both sell them.

Make sure your check valve at the vacuum reservoir is in good condition. If the vacuum booster does not hold enough add an add on unit like mentioned above.
