If I was you I would just run the 7XL on 4s for a while and see how it goes before spending another $280 on a motor. Unless you know you'll get end up getting a neu and can't wait or you want to sell the 7XL as hardly used.
I have one in an E-maxx (7XL), it's pretty fast and does rolling wheel stands easily in second gear.
Heat might be an issue with it in 15 minute races on a hot day, I'm not sure.
I've only had mine a month and it's been 90 degrees plus every time I've used it, the hottest it got was 155 with 12 cells and 51/13 gearing (I think it might be under geared by a tooth or 2 though), with the Rc-monster heatsink and no fan, running for 8-10 minutes. So with a lighter car, smaller/lighter wheels,correct gearing and fan it might be ok.
7XL shoud be fast enough to do 35-40mph in a buggie IMO. Heat after 15 minutes on a hot day would be my only concern, but then I don't have batteries that will last 15 minutes so I couldn't say for sure.

I agree w/ Patrik. Run what you got for while and get a feel for what you like and dont like about the current setup. then you can make a more educated decision as to what you want in your permanent high end motor. And by then who knows... CC my even have the MM software update out and the cogging isseus fixed.
