I'm setting up a racing program with Pro-X Carrera classic nascars. These are very similar to the analog versions of these cars.

The problem with Pro-X is that it doesnt provide dynamic braking, and because the nascars are so heavy, they are slow to stop. Also, they have a top speed that is higher than practical, I would rather have more torque.

I was thinking of doing two things: Getting a motor with higher RPM and using increadibly short gearing. I want the cars to have slightly lower top speed, maybe twice the torque, and ALOT more natural drag off throttle.

Can anyone recommend a good motor/gear combo that will do this? How many teeth on the pinion and crown gears?

I want these cars to drive and feel like big american cars. Tail happy, and gobs of torque. They are bricks to begin with and need more muscle. I cant remove the mags because they help the braking.

Not to be a nuisance but if you gear these things the way you're talking, traction will be almost nonexistant. If you want to improve braking, hook up the brake wire on your controller
I have a Torino, it drifts pretty well too but I like cars that drift. If I needed more oomph I'd make sure I had a good power supply first then tailor the motor and electrical system to it. If you're just using wall warts then you're already maxed out.

I'm in Maryland too. Only just started fooling with 1/32nd scale cars this year and I'm doing extremely poorly so far but what can you expect from a newbie?

abill - with digital, the motors are buffered from the supply by electronics, so conventional brakeline cannot be implimented.

Even if carrera adds braking the nascars dont feel right.

They have a high top speed but not enough acceleration. I think at a minimum im going to try a differnt ratio.
