I am having a problem with the math end of the dyno results by Kenne Bell. 620HP to the rear wheels. I've always been lead to believe that one gets at least a 20% to 30%...sometimes a bit more drop in HP to the rear wheels. Here's my math problem. We have smart folks here help me with this. A 20% drop in HP to the rear end would be 707HP -141HP= Approx. 560HP. The dyno test showed that there was 620HP to the rear wheels. If you read, the dyno test was in a controlled atmosphere and done by an independent party. Hell, it got 579ft/lbs of torque at 4100 RPMs. My question. Did dodge low-ball the number like they did with the 426 street and races HEMIs in the 60s? Or did the drive components become so efficient that there is less inherent drag through the drive train? Splain dat Lucy!
