{{Note1}} Some dynamic compression rtatio calculators (like KBs) ask for an additional 15 degrees of duration be added to the IVC @ 0.050" lift point figure. This works OK on older, slower ramped cam lobes, but the faster lobe profiles may need to have 25 degrees or more added to be accurate.

{{Note1}}If the intake valve closing (IVC) point isn't known, it can be calculated:
 +
# Divide the intake duration by 2
 +
# Add the results to the lobe separation angle (LSA)
 +
# Subtract any ground-in advance
 +
# Subtract 180
 +
This result does not need to have any amount added to the IVC point, like the KB calculator calls for.
