This year at the planet sand drags there was only one 4 stroke that got into the 3's, at a 3.96 I believe (I think, but there might have been one other one). And Im pretty sure it is the world record for a 4 stroke (quad based motor). I have seen guys run faster times than that on a stock cylinder, stock stroke banshee. But from what I have heard floating around on planet sand, there are guna be some pretty fast 4 strokes down there next year. But I know they still aren't going to be close to the banshee's. As far as the turbo's go, there was a turbo banshee down at the PS races that had stock cylinders, stock carbs, and I think stock stroke and was running "3.60's". To me, that is quite impressive. Anyone else know the bike Im talking about, it had a yellowish green frame, and sounded sweet.
