First off it doesnt take more than a 416 to beat a Raptor. I just got back from PISMO Beach and my buddies and I found a Raptor that wanted to see how much faster he was than our 400s. Two of my buddies have pretty much everything that you can do to these engines and still stay at stock bore and they had no problem staying right with the Raptor. It was neck and neck the whole drag. ANd that is at stock bore. We later ran into a guy on a new DS650 who told us that there was a Curtis Sparks 416 out there that could not be touched. No Banchies Raptors or DS650s could keep up with him. You all can say what you want about the Raptor being faster or the Banch being faster stock, but I have seen it with my own eyes these 400 can hold there own against Yamahas best.
