I thought only the RAM had the 390HP hemi this year? The commander, grand Cherokee and Aspen are supposed to have to 360HP. So the heading at the top makes no sense - what were they testing?

That dyno measured the Horsepower at the rear wheels not at the engine. And since the automatic transmission,driveshaft and rear take up about 20% of the engine's 390 horse power your left with around 300-320 horse at the wheels.

Curious to see if an intake and exhaust really truly make a difference on this truck. B/c other than a lot more noise, I think you're only going to see maybe 5hp extra, tops.

thats why these trucks are "fast" compared to most of the competition. even if we end up with 300-310hp at the wheels. thats what stock chevy z71's are putting at the crank!!! that is a huge, difference
do your rams have a hard time down shifting when dynoing? I had to remove the speed limiter in order to keep the truck in 4th for an accurate dyno pull.
Doc and M15 PM if you guys ever got some free time, be cool to check out your trucks. Maybe on a weekend or something.
