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.
