Hi everyone

There has been quite alot of discussion in other/past threads regarding ducting cold air to the rotors.

If you do so, make sure that air is not just blown to them. Especially don't blow air against one part of the disc.

Otherwise, the uneven heat distribution will result in the rotor distorting.

The correct way to vent the front rotors is to duct air INTO the centre of the rotor from the rear, such that air is distributed through the venting holes sandwiched between the rotors.

OK, I gotta ask...

If I aimed the pipe to point from the center of the disk to one edge (i.e., one edge of the pipe lines up with the center, one edge lines up with one rotor edge), is that REALLY going to make a difference? The rotors are spinning fairly fast, even while turning, so I just don't see where you could get hotspots on the rotor...at least enough of a temp diff to worry about warping.

Anyone?

 

As far as I know - rotors spin. Therefore you aren't directing airflow to certain part of the rotor.

I think a bigger concern for rotors is not to apply the parking brake after a track session. That will warp your rotors.

 

meat - yup, dont' apply that parking brake! definately a good tip.

even if the rotors spin, maybe because the ducting will not throw rocks around up there, but maybe dirt will pit the rotors, and this prevents it? but I believe the idea of cooling by pushing air through the vanes from the inside sounds logical in theory - but I'm no engineer.

 

Even where no air is directed upon a rotor, depending on teh construction of it deformation can occur.

Let me go back and take a squiz at that article and I will elaborate tommorrow
