Re: CFM (UB2 SLOW)
usually it is around 1000cfm, however there are many companies that have some highly ported models which will achieve 1200. the important thing to remember about stepping up to a higher flow throttle body is that your engine can only handle so much airflow. if you have an engine which can only handle 875cfm, and you put a 1000 cfm 58mm throttle body on it, you basically loose a lot of your throttle range, because that new throttle body will be flowing 875 by the time your foot is only 3/4 of the way to the floor, so your throttle definition becomes terrible, and you will only use about 3/4 of your pedal travel....i hope this makes sense.
