I've got a 14v 1100 mA and a 14v 1500 mA transformer (Electronic Power Boost model).

Unable to do any real testing right now, I would assume the 1500mA to be more powerful, and therefore make the car on that track go faster, right?

I've tried and there seems to be a small difference but it's quite difficult doing it scienticially.

I'm requesting my dealer to change the 1100 mA into another 1500 mA?

Hi there schnuz,

Over all, voltage is what determines the speed of you car on the track, so the 1500 mA transformer should give the same car speed. But sometimes due the electrical resistance on large layouts and when multiple powerful cars are running 1100 mA will not be enough to fully supply the motors with the electricity they need, so in that case the 1500 mA transformer would give better performance.

The voltage might determine the top speed, but the available amperage is what will provide better acceleration. electric motors generate their greatest torque at standstill, but that's also when they draw the most current. You are not going to feel a lot of difference between 1100 and 1500 mA power supplies. Try something like 3 to 7 Amps and see how much faster the cars accelerate.

I'm using a Terminal Track Plus from SCX so I have two transformer connected at the same time, each transformer to a separate track.

I can see a performance difference when using it in single mode (one transformer pr. track), and it levels out when I set it to dual mode (two transformers providing shared current to both tracks).

It's not a big difference but I believe it's there.

To be sure I'd better change them to be identical I guess, but thanks for the replies.
