Thor 45 with Zoar 20x8
OK I bought this engine in a ready to fly plane that was never flown. It has 4 tanks of fuel through it, still running the rich oil mixture for break in. LawBoy ashless (32-1). Aftermarket wrap around pitts muffler and has the velocity stack on it.
I am locate in Sunny Las Vegas and temp outside was around 95 degrees. I am not sure how the numbers compare but here they are
Zoar 20x8 max rpm: 7100
