The air gap does have something to do with some of the heating I"m sure, but not all of it. The advantage of the Sintered doesn't come from the size, it's from the materials.
Tuning Tuning Tuning. I'm sure at one stage someone will come along and offer different "parts". That would like someone offering a different arm, or a different can now. It's okay, you can do it, but it's not technically legal. Some places this is a non issue though.
So yeah, one day I hope there is a big aftermarket following of parts and support items for BL. It's good for competition and makes the big manufactures work their butts off to stay on top of the game. How realistic this will be I don't know.
The idea of "tear down" BL motors is great, I'm sure winders will think they can make them better one way or the other. But we've spent a lot of time and effort to make sure "we're" doing it the best...
But there is a lot more to winding and producing a BL motor then there is to a regular motor.
Just the machine we use for Timing the motors accurately is kind of out of hand.
In the oval scene, there are a bunch of guys that run better bearings in the motors, and find lubes that are "magic" if you will. This is just the beginning of it. I can see later on guys zapping rotors, and balancing shafts to the umpteenth percentage of 0.0000. All of this is something that "will" happen. We're racing here, and if the rules don't say you can't do it, someone will.
I don't think it's really all that realistic for aftermarket "rotors" though. In order to make them competive price wise, you have to deal in some pretty big quantity. As it stands right now, BL motor Rotors are not interchangable between different manufactures. They can be "made" to be, but still, you'll be cornering yourself to one brand. It's difficult for a manufacture to do that. What if we change our basic motor design just after this guy goes out and orders a 1000 of them? We've no plans to, but how does Super BL Aftermarket Motor company know that?
Even now, the biggest advantage to your motor is a good handling car, and the proper trigger finger for the race. That is by far the biggest tunning tool of any motor program. Make the work for the motor easier.
What we've found in all our testing and monkeying with timing is this: The motor only makes so much power. Move the timing, you move where the power is, not how much there is.
That's it. No tricks, no magic, just the plain old physics of it all.
Its by no means the same as BR motors, they are a different animal with a different set of rules.
From my experience working with all our team drivers, and "Racing Customers" at big events, I've encountered very very few situations that we were looking for "more" power. Typically they wanted less power. In many cases we loaned out slower motors to use.
