I fired the 120 SC up and all I can say that thing is a ANIMAL!!!!!!!!!!!!!!!!!! Talk about some awesome power,and all I had was YS 20/20 fuel I can't imagine what it would do with 30 % in it . As it is now it will hold a 1,650 idle all day long, at 4 K its a tad rich, regualtor I suspect and wide open was just a short burst just long enough to get a reading 9480 and it's still a little bit fat. So I guess my 16x8 is going south for that engine. I think a 16x10 will be just about perfect for it.

Thanks again for all your help
