Questions on Hydroboost

[grobb284]

I was looking at the Bendix hydroboost models, and see that some have reliefs, and other do not. I assume that this is to keep a uniform pressure in the accumulator? I am using a 2002 Camaro PS pump. Does it have an internal relief? Failing this, is there an external relief that could be purchased?

Also I have seen different bore sizes for the Bendix Hydroboost models. I understand a bigger bore size will have more boost. Is there a known bore size that works well with something like the weight a C3 Corvette?

I am using C5 calipers front and rear.

The bigger the better, probably. All of them should have the same guts. The old ones looked different. The newer ones have a big accumulator cylinder attached.
