# How does the summit racing cam timing calculator work?

## How does the summit racing cam timing calculator work?

It converts duration, lobe separation, and advance into the four individual timing events that will ultimately dictate engine performance. It also works the opposite way. You can tweak any of the four events in the calculator to learn what the resulting duration, lobe separation, and advance would be under the new conditions.

## How to calculate valve overlap in camshaft calculator?

Camshaft Calculator. An interactive camshaft calculator where engine builders can see how valve overlap (and boost efficiency) is affected by a camshaft’s physical design. When shopping for camshafts from different manufacturers, enter each of their supplied cam card specs into MGI’s Camshaft Calculator. You can compare up to four cam cards.

How to select the correct camshaft Tighe cams?

There are many different programs available on camshaft selection Ivan Tighe Engineering are currently investigating these programs. The programs tested are very accurate if a Chevrolet V8 is the test engine, but if a 16v Suzuki is tested, in particular parameters the selection does not work on the dynometer.

### Can a camshaft be replaced with a solid cam?

If a hydraulic cam is being replaced with a solid cam, the 0.050″ duration needs to increase by 80 or 100 to obtain the same effective duration. For every 10 CI. (200cc ) the duration needs to be increased by 10 at 0.050″ to have the same effective duration. This is more effective in V8 engines rather than 4 CYL. engines.

### Why is timing important when choosing a cam?

In previous articles, we’ve talked about the importance of Considering Individual Timing Events When Choosing a Cam to help us determine the duration, lobe separation and advance needed. This is especially important for cars with electronic injection which are dependent on idle vacuum to run correctly.

How can I choose the right camshaft for my engine?

It isn’t always obvious which camshaft we should choose for our engine build. Even when we fully understand the individual timing events and how each of them interact in a four-stroke engine’s piston and valve motion, the complexity of it all can bring confusion and uncertainty to the cam selection process.
