I wouldn't mind testing one for a while and comparing it to a well built twin blade.
Do i think either one will actually replace a well built dominator?
No, i don't, nothing has yet in Carbs.
Do i think this might work well for those that need more cfm but are limited to a 4150 style carb?
It might, the Twin Blade sure does.
Until i see more I'm going to have a hard time believing it will flow as much as a Twin Blade , much less a Dommy.
Would love to spend some time with one though.
