Onservation about magnum 5.9

Electric water pump on the $5500 mag vs the stock mag w/mech water pump.
The power diff can be huge. 30hp

Doesn't look like they ran a belt on the stock 5.9 in the test. So apples to apples?

Assuming you mean that there could still be a difference in power between the 2 motors since one had an electric pump and the other didn't.
