Any one know the rpm rating of the Scalextric motor?

Some Scalextric cars are faster, is this a different motor or gearing?

Stronger magnet in some the Scalextric cars is this from 2 magnets or is the strength varied?

I should start pulling my cars apart!

All scalextric cars come with the same 18500 rpm Mabuchi motor. The gearing is the same aswell, although the sidewinder ratio may vary slightly from the inline ratio.

All bar magnets should the same pull (guass) as should all button mags, black mags etc.

It would be nice if the motors and mags didn't vary so much, but yes they do. You can search the site and read more. Try "motor variation". We've had these discussions many times. Like motor oil discussions on 1:1 cars and bikes. (Not the DREADED OIL THREAD!!!) Bottom line....if you want to really tune these cars up the motor usually gets tossed in favor of a Slot-it or some such. Most all the other parts are changeable/ modifiable too. Loads of discussion on this forum regarding the tuning of Scaley (and everything else, for that matter). If you can't find out about something slot car here, then you probably don't need to know it. We have many good voices here. Now it's back to the bench for me

magnatism to the rails will vary depending on distance from where they are in the chassis to the track, and gearing will be affected by wheel/tyre diameter. Also the new F1s (walrus williams & renault) have a different motor - the small motoGP one. But other differences are due to tolerances.

There are different types of magnets in the cars, but this might not be very obvious from the underside of the car. On my recent cars there are two different types of bar magnets. One thin version (as in the GT40) and one considerably thicker (as in the Camaro). The thick version has more magnetic pull than the thin one.
In addition the Lister Storm has a magnet that is thinner in the middle, but I don't have that car, so I don't know how obvious the difference is from the outside of it...

Also, in my experience, there is sometimes some individual difference between the magnets of same size, but not very much.
