Camshaft And Valve Timing Event Articles

To some degree engine dyno simulation programs are useful for doing a bunch of comparisons when the real thing is out of reach.
I bought Dynomation thinking I could also learn something about the relationships of various changes to outcome.
It still a struggle - because without the experience its harder to judge when you (I) have made poor inputs. Garbage in = garbage out.
One thing that threw me for years was that the stock engine simulations were not matching real life dyno curves.

What was interesting was we got pretty good match when we compared simulations of the Zebra-Dart's 318 to the actual dyno pulls.
Thanks to Wyrmrider this past year finally figured out what was wrong with the stock simulations - the chrysler cam specs.
I know the better simulation programs aren't cheap, but for some of us they are a cheaper or more reasonable way to see the effect of cam events than swapping cams in our engines.

Now if they would just simulate a part throttle pull....
