Hey DC...
I did consider replacing the basic fan with a squirrel cage blower, but the reality is that the windings just aren't designed for that kind of abuse.
The more I think about it, the more I'd be well served to learn about motor re-winding (at least on this small (under 4800watt) stuff).
The motor is hitting over 6000RPM at no load and is likely close to it's limit before it starts to let loose. Where a heavier armature would lower the RPM and offer a majour torque boost, which is what I'm after.
Think about the Dirt-E as a two wheeled tractor
