Okay i think my math is right if the piston speed in a motor at 9800 rpms is 5,917.67 feet per minute would that be bad? i compared it to a B16 and the B16 would need to be at 10,373rpms just trying to see if my math is right and is the piston speed to high in that motor.

 

use (.166 X Stroke (in.) X rpm X 3.28) / 60 as the equation. you shouldn't use feet/minute seeing as that isn't using Si units. i have no concept of feet/minute. this equation i put above is meters/second.

 

okay i did that and it comes out to 321.93

 

damn, that's pretty damn fast. i calculated what the piston speed would be on a stroked to hell H22 (stroked motors have higher piston speeds) and it only came to 292 m/s. a stock H22 has 259 m/s and that thing has a shitty 1.57:1 rod/stroke ratio. oh but then again you're doing it at 9800 rpm. i forgot about that. i calculated mine @ 8000 rpm. yeah i guess that sounds pretty good.
