Pretty cool. I downloaded it. If it ***** my computer up you owe me a free custom cam though. lol
Out of curiosity, does anyone at cammotion know Jeff Wahlberg? Owns Custom Automotive Machining in Houston, Texas.
No worries on the calculator, we created it ourself and placed it on our own website. The code is very compact and is only relevant to the Timer's function. If you get it directly from our site, you are good. I will ask if anyone knows your friend.
I like it! Should help a lot of people out with cam questions. What duration is the calculator set up for, advertised or @ .050? Or is it setup give people the chance to check it at both?

This calculator works regardless of whether you are using .006", .050", .200" or whatever lift you want as long as all of the data fields you are entering are using the same relative lift.
Could you show us a few different set ups with changes and describe in generalities what these do to engine characteristics? That way I can be a cam expert. lol

Seriously though. Be a cool little lesson.
That would be quite a book to write.
You might start looking at some different engine builds and plugging the camshaft specs into this calculator. When you do, make note of the 4 valve events, overlap and how they differ. After a while you will start to develop a frame of reference. Once you have this familiarity, you will likely start to draw your own conclusions. Post up your specific observations and questions as you go.
Here is another handy one for you all. It is a static & dynamic compression calculator. Like the Cam Timer, it is quick and easy to use, allows you to update any field (except for the calculated compression ratios) and you can have multiple instances open at once, which can be very handy when comparing different compression or camshaft scenarios.
