Hey Bill - there's a guy here in the NE who I understand had a mechanical pump on the S5 motor. He'd run OK for 3 laps and then crap out. Took him forever to figure out he needed the electrical pump.

I'm no expert - but this guy had the worst luck at the track until he got this sorted out. I'm pretty sure his name is Mark Lovell. Mark, if your out there let us know what you learned.

Cheers,
