Would this setup work?

[IGT_7x]

Okay so here's the deal, I recently converted my HPI MT2 to brushless, it now has a longer chassis so it's closer to 1/8 scale. I'm using a Sidewinder/Velineon 3500 motor combo on this & it's getting decent speeds but not what I really want. So I was thinking since Castle is having a clearance sale right now, would a Mamba Max/1512 1800kv motor combo work? I probably have to install a BEC to run 4s but I just wasn't sure if this setup would work, any thoughts?
