·F1 and Indy are NA now but they were at their fastest when they used them. They would still be using them not restricted from using turbos as they are now. Bikes switched to turbos when the went with this generations higher reving engines. In the past the supercharged bikes were faster, than the turbos of the day.No offense, but you're all over the map with your engine knowledge. F1 and Indy are na motors. Top dragbikes are turbo. Top jap car drags are turbo.
