HV-Maxx or something else?

I have almost a stock e-maxx i was going to get the HV-Maxx but found this forum. I would like to get run times to what i have now which is 11mins off 14 cell GP 3300.

Since i have 6 seven cell packs already i will be using 14 cells so what motor would be best? I did a search and it looks like most use the warrior 9920 for a esc. I need more speed and power to beat my friends HV-Maxx. I'm likely to add even more cells later on after i get used to the power. :027:

I have a bunch of pinions already so i would like to get a motor with the same size shaft as the stock one if possible. The pinions came with the emaxx i bought it off ebay and it already had cvds installed and differant diffs.

How do you know what motors have the most power and speed by looking at the specs? The more RPM's you get the better for speed? Can someone explain what each BL spec really means.
