That's right turbos are the way to go.
Gosh they are all crazy nitro thruster, well when you want to speed up your motorcycles you can really go as much crazy as you want.
Huh really makes me think like couldn't you just get out of all rules and attach a real powerful turboprop exhaust noziles and maybe attach some wings and no one can stop you from flying hehe, maybe I would attach some parachutes for safety hehe.
