Re: Treadle Vac Conversion

The current booster portion is sort of in the same location but goes off at 90 degrees with the master pointing at and is near the engine. The whole assy is at a very severe angle and was hard to mount so not a good solution -- but it does work and maybe a bit too well because it is very sensitive. Don't have any really clear photos but maybe you can get some idea from these.
I believe with a revision to the bellcrank one of the thinner Electroboost masters could mount parallel to the firewall just above the steering column. It might mount level or at least be at a much lesser angle. Not sure but it might even fit pointing the other direction to be partially hidden under the emergency brake mechanism. If so, that orientation would mostly solve the "mod in your face" situation but which side the ports exit would determine the placement and direction.
A revised bellcrank and part of a mount for the master could be built into a sturdy short tube like module which would fit before the first vent section. Being hollow air flow could be maintained. The original short vent tube could reattach to the module and its length could fit into some of the space where the flexible duct is now. Reinforce the firewall with a plate on the inside and bolt thru the firewall and plate to have the module assy cover the vent opening on the engine side.
In the AC setup, the module would go in front of the Tee section below the blower. Of course that would take some more design because the blower doesn't have much leeway in where it can move. It might need another mod to the existing AC Tee section to fit on the module and the on/off flapper valve.
