I don't recall the amps, but I am certain it was at least 30A continuous (and likely more than that), so 100V X 30A = 3,000W minimum with occasional higher peaks. I believe at the end of the race, you could smell the baked varnish vapors flowing out the ventilation holes...(wish I could have been there).
This is almost all completely wrong. It was run at 30s (126V hot). It was liquid cooled with 600ml of synthetic tranny fluid. I trained a while, but had ACL surgery 2 months prior, so my strength was limited. Also, in retrospect, I doubt my pedaling was much help. I wish I wouldn't have pedaled at all. It was run at 22 amps max, cycle analyst limited. There wasn't any smell/leakage. It was just that my temp gauge had a wire come loose toward the top, so I had to speculate as to what the max temp was. The wire loosened at 100C, so I guessed at a peak temp of 119, but it could have been much cooler. I did run the bike at 30s and 60amps for a while after, but have since run it at 25s and 65 amps for the last few years. No problems. Hope that clears it up.
