Power assist brakes, Has anyone done it? Options

[theer]

I Race an LS2 powered 914 and an LS1 powered 944 with a bunch of other guys. The 944 has a Ford hydro-boost system in place of the stock vacuum booster (no room with the v8). Works great, if maybe a little touchy for my taste.

The 914 has upgraded Boxster brakes, but no power assist. I like it better, but everyone else prefers the assist.

Has anyone figured out a way to get power assist for 914 brakes? We are pursuing an idea to use a Tesla brake module in the front trunk, with a stock MC (cap off all but one brake line) driving a slave cylinder which activates Tesla master. Even Better would be a electro brake module that’s hydraulically activated directly from the master…

We are still brainstorming, so any ideas are welcome!

Thanks!

The proposal to use the stock master cylinder, the slave cylinder, and the Tesla system in series is a death wish. (IMG:style_emoticons/default/screwy.gif)

There is no braking redundancy - all braking is dependent on one line. A failure of the master or the slave cylinder means you have zero brakes.

There would also be outrageous lag time and hysteresis.

Stick with something that is tried and true like the typical dual master and bias bar racing set ups mentioned above. There is absolutely no need for assist on a vehicle as light as a 914. Vacuum boost has its own weakness on track due to lack of vacuum from the engine. I have set up much heavier race cars (ie Viper) with the Tilton set up and there is no need for vacuum boost.
