WOR Dyno Day 2009 at Colletti's in Dayton. This is runs 3 and 4. I premix a lot, and tuned the computer to dump mass amounts of fuel on overrun to try to keep things internally cool, so it smokes a lot (or just backfires) when you let off the throttle.
Sorry for the shakycam - I was a little nervous!
End result - 170whp four times in a row. Either it's not heat soaking, or that's how much power it makes when it is heat soaked! Which is nice, because that's how it gets driven.
