In today's video we test the stock 420cc Predator and the stock 459cc Max Performance Predator Engines from Harbor Freight. I show how to properly install a 40 series cvt / torque converter rated for 8hp18hp engines on a gokart. Then we put the two engines onto the blueberry go kart and take them for top speeds, 030 mph, and timed track laps.
