The BMP-3’ engine is mounted under the floor in the rear. The engine on one side, the transmission and PTO on the other. The PTO is for the hydrojets. And IIRC it’s a 500hp engine in the BMP-3, and the Russians don’t have anything more powerful than a 1,250hp turbine that’s small enough to fit a tank.

And IIRC it’s a 500hp engine in the BMP-3,p> Which was the same HP as the Ford GAF engine in the WWII U.S. T26/M26 Pershing. Though I doubt that the Soviet rating was in SAE Brake HP, and may well not even be directly comparable to DIN HP ratings.

I've crewed in an M4A1E8 with a GAF in it. The transmission/clutch/final drive handled it quite well, as did the Israeli reengined Shermans that used a circa 500 HP Cunnins Diesel.
