I know someone who used the 1512 motor, and a 5s lipo setup. VERY fast. But not 65mph, and 85mph would require more. I'd imagine that 55mph is well within the reach.
First, those big wheels that buggies use they aren't aerodynamic at all. The exposed suspension arms, etc...
Also, the AWD system with its 3 diffs creates parasitic loss. If top speed is your goal go for removing the front diff, and creating it as a RWD platform. A 2spd transmission from an OFNA Ultra GTP would go quite a ways towards your 65mph goal.
Buggies are better off than truggies or monster trucks when it comes to drag, but that big wing to keep them stable causes lots of drag. Its possible to eek another 5mph or so out of a buggy by removing the wing as long as its drag limited and not gearing limited.
My Jammin buggy clocked 53mph on a Sheriff's Stalker radar gun with a OS 30vg using 30% nitro and a 15t CB. This was in a small parking lot with about 150ft of running room. Not very much.
Using a GPS we clocked my 528xr powered LSP at 39.6mph using a 15t clutchbell. However, the engine was only temping 170* and I broke a hub (stupid freakin hubs) before I could tune it leaner.
