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! |

Thanks guys- the objective is to reduce the pedal pressure. We’re team of Oldtimers and everyone is used to power brakes in DD and the other race car.
Does a dual pedal system make the brake pedal “easier”? |

QUOTE(theer @ Mar 24 2025, 06:27 AM)  Does a dual pedal system make the brake pedal “easier”? It can. Size the masters for full pedal travel and max out the pedal pad position for max leverage. Tilton can do the math for you after you fill out their form. One option would be mount an overhead pedal and bolt the booster/master directly to it. Stock gas tank would be in the way. Your idea has too many possible failure points. |
