Which will produce more output?

So I have a new quark ssb and am wondering what to do with it!

I have a novak hv 6.5 with 5mm shaft. Plan is to run it with the quark on 3s lipo and get a feel for how the sensored function works.

Now the vehicle i will run it is is kinda special. It is a tube buggy based on xl5 pede parts. It is around 1/7th scale and is 2wd. I have a 9l in it right now, and it is geared for 50mph. With the same gearing the hv 6.5 should do 55mph...

I just wonder if the hv will do as well as the 9l? The rotor is smaller in diameter but a bit longer, and the motor is supposedly more efficient?

So whatcha guys think? I will try it out and see how good the quark is. I plan to use it box stock, no ubec or other mods. The buggy is lighter than an 1/8 buggy, but not by much. Fun to run as it has plenty of suspension travel, no swaybars, and 2wd brakes!
