Re: DO NOT TRUST BTV

I have not, but doubt there is otherwise it would surely have been mentioned by someone already.

Several sites sell the Chevy kit but as mentioned, it is mounted higher up and level on a Chevy where length and width not an issue. We would need a remote fill for the angle and location under steering column. No idea where/how the BTV was mounted on other cars that used it.

Biggest question would be since the BTV has a single approx 6" power cylinder and this is dual 7, would that be enough to overcome the 1:1. As Craig mentioned, his single 7 was not. There would also be another pressure difference and volume tradeoff in the fluid portion as the BTV has a narrow long stroke "piston" that displaces or squeezes fluid out vs the shorter 1" cylinder on the replacement which pushes.

The volume & pressure loss still may be enough to kill the possibility even with larger booster. I noted Jerry went to a larger cylinder from what he originally drew. My guess would be maybe a narrow cylinder, even though it would provide higher pressure, must have volume limitations.

If this wouldn't work, then the only other option I can see that may work & be small enough to keep things in the same place and geometry would be to use something like the ABS electro boost. That is small, requires minimal plumbing changes & components can be hidden. Pressure output is adjustable to way over what we need so should compensate for the 1:1.. It's also pricy & 12v only.
