Right now I'm running the MMT with only around 3600-3700 watts and its heavier and less aerodynamic, and its not even getting hot at all. So 1hp extra should get me another 10mph or more right off the batt with the right gearing, plus I should be able to gear up more from there. Maybe my thinking is off...

It will come down to gearing too. My BPP with 10S geared the same as 6S with the 1521/1Y at close to it's rpm limit pulled 4760 watts. You might see 100A, 80A or 200A. If you use the 100A 12S controller with the 1527/1D, you might kill your controller. Might not happen on the first run, but it will happen soon. I think that's the reason my HV110 failed, but the Schulze 40.160 is still going as it can deliver that kind of power and more.
