Mine is getting ready to head out. Not sure how it will run. I made up some resin cast of motor magnets, drilled holes in them and added 4 of the rare earth magnets (quad set up) you buy from radio shack. The car has no track time so we'll see if I blow up before Ron does
Cool concept! Kind of the magnetic equivalent of a dual spark ignition system. If it works well, magnet position can be shifted and used as an alternative method to adjust timing. With all the talk of fireworks maybe we should have held this race on July 4th.

I'll cast them pre drilled if its something we can work with. My original design (in my head) was to be able to push the magnet in from the back side and leave the front mostly enclosed, just enough so the magnet can't slide all the way through. I was thinking this might be a cool tuning aid for taking some magnet strength out by adding plastic spacers before inserting the magnets. I bench tested with the polymers but they seemed like too much for this car. We'll see how it works this weekend.
Good luck with the new club Dog. I wish I was closer, sounds like a good time.
I keep coming back and looking at those "magnets'" of Sam's. I agree with Ninja on being able to move the magnet to adjust the timing. Funny thing is, when I was at the LHS last weekend I was looking around and I spotted a plastic container that looked to have about 20 or 30magnets, maybe more, in it about that size for $13 or $14. I'll have to go back to find out what kind they were.
Blacktop Raceway should be getting busy today and tomorrow with the rest of the cars rolling in. It's great to see the new season starting off with a bang. (From the sounds of it, with these front engined dragsters, there be a lot of it. Mine included!) Maybe this race should've been called the Up in Smoke Nationals.
