Enter the maximum lobe lift and the rocker ratio into the Valve Lift Calculator. The calculator will evaluate the Valve Lift.

## Valve Lift Formula

The following two example problems outline the steps and information needed to calculate the Valve Lift.

VL = LL * RR

Variables:

- VL is the Valve Lift ( )
- LL is the maximum lobe lift
- RR is the rocker ratio

To calculate valve lift, multiply the maximum lobe lift by the rocker ratio.

## How to Calculate Valve Lift?

The following steps outline how to calculate the Valve Lift.

- First, determine the maximum lobe lift.
- Next, determine the rocker ratio.
- Next, gather the formula from above = VL = LL * RR.
- Finally, calculate the Valve Lift.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

maximum lobe lift = 30

rocker ratio = 1.25

VL = LL * RR** **= ?
