2.5" pully on the M90

[SuperRunner]

Does anybody here run the 2.5" pully for the M90? If so, what PSI are you able to get and what kind of power? I am going to go ahead and give it a try.

2.5" is quite small and prone slippage.

that sucks. I guess I could always re-route my upper radiator hose and put in another idler pully to help pull in the belt.

I saw someone who made a 45 degree adapter hose mount and had it aiming almost upward then used a flexible line and routed around the SC belt.

With your after cooler, colder air will be less dense so less pressure but you will have more air if that makes sense so more power.
I would think it will be around 7 psi.
With the extra torque you will tend to short shift anyway and not over rev.
If it does slip buy a can of belt grip it works wonders.
