I ran the numbers thru wallace calculator. I assumed both were installed at 109 ICL. Not sure if the calculator can account for asymmetric profile.
2802 has IVC of 68* ABDC
Crane 278 has IVC of 70* ABDC
What I don't understand is how a Lunati HR 231/239/110 on a I06ICL has a similar IVC??
Lunati 231/239 HR has IVC of 67* ABDC
Does that mean the HR will have a similar dynamic compression, even though it has 7* more duration at .050"?
