I will say I've got a spot near me that's quite rural and has a rolling spot to a fixed sign that I've previously got up to 137mph. The other evening it showed 144mph so quite the gain.
I think I'm gonna try a 2.38 pulley on it for the next 1/2 mile and see how it does along with about 20% more ethanol.

Hopefully you are logging and retuning for those changes. Pulley and higher ethanol will take a lot more fuel.
