That is quite the saw! Power output is similar to the 500i, but the fuel consumption is probably closer to that of a big block Chevy on race day. I still want one though, just for fun!
Amish logger I know is always looking for another good racing saw...I'll have to suggest one of those. But I'm not sure if they allow the suck, bang, and blow to all happen at once, or if they need to be in different steps.
Pretty impressive, amazing some of the one offs that people build for fun. Price tag of the turbine, though, ouch. Buddy is into big RC planes and copters, sent him a text asking what a Wren 44 would cost. He's got a used one he'll sell me for only $3200. About 5k new, not including gearbox and transmission.
