I am currently running a 9920/8S combo in my all aluminum FLM Stampede. I'm running 17:87 gearing and clocked a max speed (GPS verified) of 29.8mph on a 6cell GP3300 matched pack. With 9 cells, I should break 40mph easily which should keep up with your dad's Revo.

With a 6L, you should be able to get a tad bit more speed on 6 cells. I can probably give you more info this weekend on that as I have a 6L on the way to go in my relatively stock stampede.

Also, as someone said earlier, go with the rustler. Stampede will wheelie way to much with the kind of power we're talking about. My rustler rides wheelies all day with my Etrex strapped to the front bumper.
