I think what Peter is trying to say is you may be better off changing the crown than the motor. A 28 instead of the standard 27 would be cheaper and more able to push the stronger magnet and as you said you only have shortish straights.
Your only problem is finding a 28 to fit the Scalextric rear axle. If you do it would be easier to file down the Knurl a touch under the wheels once removed as it will make it easier to slide off the crown. It isn't too hard if you are careful.
You could try putting an 8 tooth on the motor but this will lower your gear ratio more than putting a 28 crown on the axle. Probably the easiest option though. Make sure the pitch suits the crown though.
The problem with changing the motor is that the style of motor in the Scalextric F1 is low on torque and the revier motors are even more so.
