If you stick to 2P, you should be good upto ~140A, so I think the 1700kv 1515 would be a monster, but very doable, esp on a 160A ESC (I'm upgrading my prediction ;) ).

Finnster, couldn't find ZPBs Revo, but I did find his insane twin motor, twin MM Maxx, that thing is nuts! The good news though, I think we've solved my "problem" :-) I've pretty much decided on the MGM16024, and the Neu 1515 2.5d/F running on 7S2P A123s. Worst case, if I have to I'll back her down to 6S2P, but as you mentioned, with the headroom of the MGM and a solid motor choice, my packs will most likely be my limiting factor and I think they'll be OK.

Now all I have to do is worry about that tranny, lol... Fingers crossed it holds up long enough for me to get things situated, tested and have at least some fun with it before it goes south on me. Worst case, it looks like I'll be scowering the net for steel\alloy gears for that three speed, or looking for some other creative way to slide a "slipperential" solution in there.

Just thinking out loud back to what you mentioned, with the three speed and first gear being so low, I should have more pinion options making me think the 1700Kv should be fine as I can gear up or down based on heat, seem reasonable?

Now all I have to do is wait for Mike to get the MGMs and my 2.5 back in stock

I think the last thing I need to iron out and I may give Serum a ping for this one, is a creative motor mount. I originally dropped my stock motor plate down by about 3/16 of an inch or so, maybe slightly more and used a simple "clamp ring" setup to attach the motor to the mount using the stock adjuster holes. It worked VERY well, but is a challenge to adjust the mesh on due to its very close proximity to the tvps... Loved Serums adjustable setup, but as of now it appears that it may have been a one off solution, I'm surprised Mike doesn't yet have an offering for the Savy, but I guess we have to work off of demand :-(

GREATLY appreciate all of yours, BrianGs and the gangs info and input on my project and please, please don't hesitate to "smack me in the head" if you see me wondering off course

If I ever get this finished (my wife just hates me spending money on RC, but hey, you have to pay to play right) I'll certainly post pics!
