How much vacuum do I need for power brakes?
We put a Mighty Demon 850 carbuerated427 with a radical cam in a 93 Cobra clone.The power brakesaren't getting enoughvacuum to work right.It's only putting out about 1-2 psi of vacuum at idle.Has anyone else ran into this?What's the best fix?Thanks

If thats not possible I did a quick search at summit racing and found an electric vacuum pump http://store.summitracing.com/partde...p;autoview=sku
