I also ran 8s1p1 a123 and peaked at 1700 watts. If those numbers are right those HO motors suck. Like I said I tried them all before going brushless and the dewalts are the most powerful brushed motors of that size. I still run one in my jugg2 on 6s 123cells. I do think the mamba can run it. Just use the high power wiring setup.

In fact there is a few more powerful brushed motor at that size. One of the most fearsome one are astro cobalt motors reaching 85 to 88% efficiency iirc.

The astro cobalt 90 is said to be able to replace a .90 glow engine on a plane... 1500-1600 watts continuous which is near a neu 1521 but at 2 pound. The good point though is that controller handling brushed motors are more robust...
