But my current design would never run 10's. Low 12's, high 11's maybe. But never 10's to hang with the big boys. And I had a quick chat with one of the Escort Z guys and they told me campaigning an all-motor setup is *MAJOR* $$$. They also thought about it and steered away. You almost have to tear apart the motor after every event to keep it in tip-top competition form. I simply don't have that kind of financial backing right now. I'm just a weekend warrior. :-)
