195mm to 188mm on E85 comparison
Points of note, the motor I just put in has 21k, and the old one had 52K.... The other moving target is weather conditions.
The heat was way less with the 188mm, see chart below, but the HP/TQ under the curve is still stronger with the larger 195mm.
These are Dynamic Dyno numbers, and no ice or spray was used on the runs:
188MM = 517rwhp/665rwtq
195MM = 515rwhp/702rwtq

You had a 20* difference even at 2000rpm so I kinda find it hard to believe that the pulley alone was to blame for this, seems like the intercooler temp was warmer to begin with. Regardless, 160* in a dyno run is pretty freaking hot.
Now, what I'd like to know is how the hell you have so much low end torque!?
