I would like to try a RB ws7II but I’m a little worried. I dont want to spend $300 bucks and then be disappointed. I am running a crono RS5, also have had a P5T and both engines pulled a couple different ws72 off the line, now my question is, do you think that was just there setup(clutch/pipe/tune/fuel) with the ws7 or will a P5 pull off the line all day long no matter what??? I have not seen one engine that has as much grunt down low as a rs5 or P5.
