great work on fixing up these old guy's, an area of the hobby that's forgotten in all the collecting and showing off hype well done

The Motor lab looks to have some parts that share with the Tekin Dyno.

I bought mine not so long ago and does a ok job so far. Testing on stock motors but thats all. Does load the slave motor up good when you want it too.

I had the Shinwa Motor Dresser back in the late 80's and is crap. Only tells you revs and amps. Rev counter is just a dial. I remember my Technigolds flat out was 21,000 @ 2.5 amps LOL. Very tricky to get 6 min . Don't ask why 6min racing in mod when everyone else was 5 min in Mod.

They did bring out a Tourque Dresser too. I never had it as i paid over 100 big ones for mine 2nd hand.

Out of curiosity, have you ever come across the Shinwa Rolling Road? It seems a better idea for testing motors in a buggy rather than the bench.

I've seen them advertised for sale in my old magazines (1990-1992ish) but never seen a picture of one.

I found that the TurboDyno actually did tell you what your motors where doing. This was especially true if you had a known good motor. Even today, a lot of the oval guys have converted the Turbo to integrate with brushless equipment and they still use the dyno.

I also used the CS dyno, which was a flywheel like the Fantom/RSR. I actually figured out a lot about the Reedy MVP when they were big as handouts in the late 90's. I think the Turbo is better, but if you work with the dyno you can get an idea of how things work, brush cuts, springs, etc. The thing is you have to translate it to the track.

If you ever have access to a Robitronic dyno then try this one. It´s also a flywheel dyno but much better as some others as the results are not dependend on the variance of voltage as it´s when using a battery. You´re using a 12V lead battery with this dyno and the voltage is regulated inside of the dyno. For this reason the Robitronic dyno was the most expensive one in the past.

I think you could convert any dyno for brushless use. The problem just is some results as power numbers or efficiency are not true anymore as the internal resistance is much higher afterwards. RPM readings are still true.
Of course you still could compare motors and a fast motor is still a fast motor.
