Dead on comments Evan! Lots of people think the Outlaws are doing well over 150 mph and up, but they're nowhere close to that. But its so cool watching it go from 125 mph to 0 mph in 10 feet or less!!!
The Jett engines would be a killer power plant for an Outlaw, but you'll have to put a little more work into preventing a nose heavy situation.
ChuckL. Do you have your Jett piped, or running the stock muff?
