I have a M150 running on a 2JZ engine. Does anyone have a good starting point for what the "Charge cooling gain" should be for pump E85? Also I was going to treat this as a linear value between regular unleaded and E85, is this a good way to treat these values or should I check the charge cooling gain at a few different blend points?

Thanks Bob

Hi Dentguy,

I have mine on 20 degrees for E85, and a linear scale down to 13 for E0, This is using a Subaru EJ20, so the values for this engine may not match those of yours due to port and inlet manifold design differences. I am planning on doing some testing for blends other than E85 and E0 this week, to see if it is a linear scale.

Thanks, Once I Get back to the dyno I'll double check all of it. Just looking for a good starting point.
