ESR

 

who has an esr 330pv with a stroker crank? or the 310 with a stroker? also does any one know the actual hp numbers for the 310pv and the 330pv?

 

I have the esr 330pv stroker.

 

could you describe the powerband? and where it shines and doesnt shine?

 

ok mine has bottom to mid porting and esr's mid pipe. The powerband is fantastic bottom through mid, mid range is really good though. It has a much smoother power delivery than my old 310 non pv. You still have the 2 stroke hit it is just milder, starts earlier and lasts.

 

ESR all the way...

 

ESR hands down......I know from experience.Had 2 of their motors.A 310 and the current 370 Powervalve (see pics)
