If brake vendors want to argue about who's bling is better, please do it somewhere else.

 

Dave, are you doing rears also? Or just front? If you are doing rears, what are you doing about the e-brake? Are you using a separate e-brake caliper?

 

I talked with docofmind awhile ago and he indicated that he was comming up with a system for the rear that would use a wilwood caliper with vented disks in the rear along with a second mechanical spot caliper to implement the E-brake function.

The spot caliper will probably be this if i'm not mistaken...

I'm not sure what he intends to use for the main rear caliper though i suspect something like this...

Though i havent done any research into it i will eventually replace my rear setup, possibly with something like the above description.

 

Mr. K.,


do you think electric powered cooling duct blower fans has any value in getting better heat management for your needs?

 

Will, I would think that would work only if you were traveling slower than the fan moved air.

 

Also, i would like to data log the heat from the front brakes to evaluate ducting. would need a thermal sensor(or 2) and send to our loggers. (i already have the sfphinctertone probe sensor deployed but no logging until further testing conditions explored.)

 

It would be a great idea if you could have two openings merging into a 'Y'. One would be from the original "fake" duct in the bumper. The other would pull cold air from another place (under the car like the C&T ducts) and contain a fan. 'T' the hoses together, and have a switch for the fan on the dash somewhere. That way if there is a black flag etc. or you can't do a cool down lap, you can still cool the system in pits or at slow speeds.

 

thats atleast 10-15lbs of dead weight you can cool in the paddock w/ water mist if you need to.

 

I looked at a couple different electric fan setups awhile ago. They seemed to be rather bulky and we dont have a whole lot of space to work with. I dont think a fan system would go along ways toward solving the heat problem as the heat build up occurs very quickly during the braking zone for a turn. Much too short a time for the fan to reduce the peak temps seen during that braking zone. However, the fan would allow for a quicker recovery and should provide for lower temps at the start of a braking zone. But my hunch is that would provide only a minimal improvement. My guess is that these systems are designed to keep the brake fluid from boiling during pitstops.

 

yeah, i agree. i believe the fans can only be of use for facilitating the radiant cooling of the brake components, but would have little to do in affecting the instantaneous peak heat from braking, although if a lower starting temp is obtained/maintained between braking it could be substantial.

Doesn't Luc have water mist cooling on the brakes of the Roush Trans Am car?
