I think it would be interesting to see a dyno run of the Cubs set up as Dan explained above. I don't think anyone here doubts Dan's knowledge. This can be argued over and over and it's still all speculation.
Who knows, maybe if the timing can be altered that much, this may be the next big thing for ALL Banshee riders. I'm not going to say it can't be done, when the cylinders have been out for what, a month? It took them almost two decades to finally ring all the HP out of a stock set of jugs. Why are we saying these jugs can never do something after a month of development?
If the exhaust port can be brought down some, these things should pick up plenty in the midrange. Unfortunatley, these cylinders have a port arrangement that is so superior to Banshee jugs, that they will probably figure out set ups on these to out perform stock jugs everywhere.
I'm speculating myself here, but I am keeping an open mind about what these can do, after all the are just powervalveles Cheetahs.
