-{{Note1}} Some dynamic compression ratio 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.<br>

-{{Note1}}If the intake valve closing (IVC) point isn't known, it can be calculated:
+{{No
-# 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.
