The Yokomo MMS is not a dyno period!!!!!!!!

The Yokomo is just a checker, the figures it gives are under no load. Dynos put the motor under load to better replicate a car being driven along.

The Yokomo is good for running in motors, finding out whether they need rebuilding, and ROUGHLY comparing motors in the pit box. A Dyno will give a much truer impression of how good the motor is.

FYI... If you have any doubts about what some of us have said for a long time... that is that Fantom Facts can't be trusted all that much... You should take a look at some recent comments that Todd Putnam has made recently over at Hobby Talk, in the Oval Racing/general_discussion section... The topic is 'new trinity 4 magnet stock motors', on about the 4th page Todd starts talking about his recent observations regarding the Binary2 'outlaw' and what his Fantom told him vs. what the track told him...

Sorry to tell you but the Fantom's program's are based on older brushed motor tech. They were a little sketchy at best back them. Just use it for the data on the motor it gives you and work from there. I have used one of these for 20 years bridging brush to brushless technology and that is all I use it for now. It is a useful tool for comparing motors and motor setups if you can get the software to work. The Windows version requires a key which only works on the computer it was issued to. I have not been able to get the older DOS version to work on a newer computer.
