racefactor might do something. My friend just bought a brand new 7 port turbo 21. and had a glitch and it took off jumped a tube and landed on its roof. The INEXPERIENCED turn marshall just sat there and let it rev out untill someone else came over and shut it off. That 20 seconds or so of revving a motor that only had about a 3/4 gallon wore that piston and sleeve out as you could imagine. So they are hooking me up at dealer cost. they are great people.
