I got both, Banshee and 450. I'll get beat up on this one I'm sure... I have more fun on my 450 doing everything but dragin. When it comes time to line up, I go get the shee. I have no problem beating lightly modded banshee on the strip with my 450 but I get my share of getting beat too. 450's are not designed to be dragers, they were designed to have great handling and quick exceleration which makes them ideal for everything except drag racing. I just find the 450 to be a more versitle machine. I think both motors are realiable with proper maintainece. Just my opinion.. Dont hurt me too bad.
