Is this a worthwhile device, or is compressed AIR just as good.

View Full Version : Brushless Motor cooler???? X man 01-06-2009, 12:41 PM Is this a worthwhile device, or is compressed AIR just as good. Any opinons Than:confused:ks Dan casper60 01-06-2009, 01:02 PM Air gets the can cold, the cooler gets everything cold. difference being the cooler has more time to cool the motor vs just hitting the can with compressed air before you make your run.

Daryl What direct proportion does it have on performance. What are the specific parameters Higher gearing better motor efficincy? not doubting you at all just want hard 'COLD' facts And understanding Cheers Dan KenBajdek 01-06-2009, 01:27 PM Colder (brushed or brushless) motors will run faster! The motor will eventually heat up during the run the but end the temp will a lot cooler. Usually we see about 30-40 deg cooler after 4 minutes. Lap times won't fall off as much or not at all. Sometimes you can gear it a little higher depending on how the car is handling. Lap times will show how heat will drop the performance of the motor. Motor coolers have time to chill the can and the rotor. The spray will chill the outside but not the core. casper60 01-06-2009, 02:33 PM Beat me to it Ken... Thanks. Heat has a direct effect on the efficiency of a motor, the cooler it runs, the more efficient it is. The helps lap times from falling off as much during a run than you would see with a motor that hasn't been cooled. The can of air doesn't penetrate past the can unless you have a process of spraying it a couple times a minute over a prolonged period of time. Most of us don't have the time to babysit the motors... one of the reasons we went to brushless in the first place!

They seem to work the best. Next time your at the track, James has one you can check out.
