my lil 6.1 died at the 1000ft mark at the track
I agree. At 6000 cross drilling has little effect. There is a way to do it that doesn't turn the crank into a pump.
Never heard about the pump issue. I'm not surprised. They make everything as small as the can. I'm sure they reduced pump volume to save HP.
I believe that most of the issues these early '03-'08 engines suffered from were the result of engineers hoping to build a performance engine (which they did) but not taking into account the conditions the engines would have to survive in daily use... mostly in trucks.
Valve seat issues... many feel that overheating causes this... certainly doesn't help.
Weak connecting rods... can't take the rpm's?
Spun bearings... I've seen rods and mains.
Weak oil pumps... the upgrades on the '09's was done for a reason.
4032 pistons... may not like high temps?
Here's a scenario... Ram pick-up... loaded to 8,000 lbs. (lumber, boat, family...whatever). 90 plus summer temps. The driver is getting on the gas to merge onto the freeway... so we have high ambient temps.. high rpm's (maybe 4-5k plus?)... light 5w-something oil with a poorly designed oil pump? Repeat time and time again.
See where I'm going with this? Disaster is right around the corner.
Chargers and Challengers present different. but just as tough, operating conditions (mostly from a heavy right foot)...
Great motors but Mopar's legendary powertrain engineering took a temporary hit...
