195mm to 188mm on E85 comparison
I just finished my rebuild and tune, so wanted to share the results before I head up to TimmayFest.
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

Did these pulls include tuning? How much timing was pulled on each pulley? Looks like the 195 has more in it top end though if you tune it.

I've been thinking a 185-190 is optimal but its hard to give up the extra low end torque the bigger pulley will give you. I don't know if its something with the Mustang Dyno or what but man your power falls off so fast and hard. If you could carry that power it would be huge. Nice seeing you car back together though. I'm just playing the waiting game and praying it will be done by October now

That was quick!
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!?

Good start, but curious on the fall-off. What are you timings buddy? Thanks for posting and glad your back up and running. I take it your running a pulley based on the OEM unit?
