Brake Cooling Setup's

[GTSBoy]

Well, I imagine that it's not the ECU doing it and I wouldn't expect anything more than turning on a pump. No modulation required. If brakes > temp threshold, squirt water, would be the logic I would expect to be involved.

The question to be asked is what are you doing with the car that requires such extravagant cooling of the brakes???

There was production cars running around Bathurst last weekend with nothing more than pads, rotors and fluid which survived fine.

If your planning to do 30-60min races on tight circuits I'd understand wanting to gear the car up like that. If your planning to run open track days and sprints then its a massive overkill.

For what it's worth the supercars don't use the ECU to control it nor do they have a temp sensor anymore.

On circuits they want to use it (normally only 2-3 meetings a year) they turn the function on in the PDM and use a lap counter activated output that references pedal pressure, vehicle speed and pressure duration to determine how long its going to spray the mist.

Temp sensors near the rotor were unreliable and inacurate, temp sensors in the callipers failed and required replacing every meeting.

The PDM method is simple (for their tech engineers its a walk in the park to setup once they have brake data), requires no more sensors that are sitting in massive localised heat and the PDM is there with a billion outputs so it may as well have been used

I'm doing a GT3 lotus exige at the moment which is having the brake ducting and PDM controlled pump refurbished. Its also got a provision to run coolant from a separate system through the callipers if the need was ever required.

can you make your bolt on parts suit the gtr Brad?

If so, i'll take a set.

Done.
