9L Vs 9XL performance in Emaxx?

[Rtsbasic]

Hi, I was wondering what the sort of power difference is between the two motors on low voltages - 12/14 cells. I have both motors although the 9L is in a different car at the min, and figured the motors lighter and revs higher..so I can get a better top speed but will it have all the same crazy torque? To conclude, I'm happy with my 9XL performance, but was wondering if theres any advantage to be had with a 9L on 12 cells.

Cheers.
