Best motor for me?

[ReV:-O]

Heya,
I'm converting a Hyper 8, and i want to do speed runs to make it achieve 90+mph.

I currently have a MMM 2200 combo, but I want to get a better motor. The reason being is, I run on 6s which is fine for the 2200kv motor, but I need a higher kv motor to achieve higher speeds, for example the Neu 2700kv motor. But running 6s with this motor will put it well past its 60,000 RPM limit.

So basically what I am asking is, what motors have an RPM limit greater than 60,000? I'm kinda thinking along the lines of plettenberg bigmaxximum, although I really know nothing about these. I will be running it with the MMM.

Cheers for any help given!
