So I checked the pulley and it is a 3.25. So with the 10 % over crank pulley, will this help up the boost , hence producing more power? I looked at a couple and most state the innovator west is the one to go with. Any recommendations on which one to go with? I was also reading that this puts more stress on the alternator, and water pump.
So I will address an error I made as I had the wrong diameter stock crank pulley.
All info is at a 6250 shift point.
A 3.25” pulley is spinning the blower 45000rpm on a stock crank. You have a lot of room to go.
Stepping up to an IW 10% will put that at 49500rpm.
Stepping up to the IW 10% and dropping to a 3.125” blower pulley will put you at 51500rpm. That puts you just under the max blower RPM.
I have not heard about issues with the Water Pump or Alternator going to IW.
I would go IW.
I plan on an IW 15% in an 8 rib setup.
