If you always do what you have always done, you will always get what you have always got.
That is the problem with diesel mind set, boost covers up all ills. Well that is the problem with trying to drag race the diesel engine in the mainstream world. Big boost makes power, but the motors are short lived make a lot of killer heat, and are sluggish. You can have the faster diesel on earth, and if it can’t win a round of drag racing because it’s sitting on the starting line waiting on the turbo to spool, what good is it. I’m building my dragster to go NHRA and IHRA mainstream racing, and have a reasonable chance of going rounds.
As to aluminum rods and weight making power, what does it take to sling and extra 11 lbs. of weight around? I have a mock up rotation assembly for a Cummins I did many years ago, and it seemed like it shaved 2 lbs. off each piston and rod.
