On the Tesla unit I didn't see much in the way of size specs. Is there info as to physical size of the overall unit, recommended ratio and stroke length needed for max fluid out?
The overall unit looks about half the length of the vacuum booster and master but maybe a similar diameter?? If so, was thinking it might be possible to make a dual stage ratio conversion package that would use the original pedal and bolt in the original spot on the engine side as per the BTV. The Tesla could bolt on the end of that package at the BTV downward angle or if still too long maybe be angled so the Tesla master end will be able to miss the steering box. The actuating rod looks rather long so wonder if that could be changed.
Another question might be how expensive is the Tesla vs the Electroboost and what kind of support or parts would be available if it needed something down the road. With Tesla having relatively few US sales outlets can't imagine there would be many units around and not sure many parts either. Would either need to come from that place in Europe doing the writeup.
So if you look at the other links on the site the master cylinder bore is 26 mm. The GenII has:
"the length from flange to the end of the reservoir is 39 cm but to the end of the master brake cylinder only is 24 cm. Center to top is 10 cm and to bottom is 16 cm..."
I did see the actuating rod does look rather long. I would have to get one to determine how that compares to the BTV and how it attaches.
That blog post did have a section testing the performance of the system. For what ever reason the link is no longer active. Ill try to keep an eye on it. I do have access to a 21 model Y that I plan on crawling around in to see if I can get measurements on the ratio.
as for part availability this set up is used on the Tesla Model 3 & Y as well as the honda accord (according to that website). I have seen this booster/master cylinder set up go on ebay for $300-$400. Another source would be to check out the website car-part.com. That searches salvage yards nation wide (including up into Canada). The wiring can be purchased from that individual or one can make make their own if they can follow along with what he did and get the components from a yard.
I am not to sure how ABS compares price wise.
