Dyno Simulation Overview:

The combination of Dynomation, Engine Expert, Engine Alalyzer Pro and Pipe Max lets us peer inside a running engine revealing (otherwise invisible) pressure waves and mass flow in cylinders and engine passages. These simulations will accurately display how much power an engine will produce, but they will also show us why it makes that power and where we should put our efforts to optimize performance!

Dynomation, Engine Expert, Engine Alalyzer Pro and Pipe Max are all well known for high accuracy and technical detail, with years of using and testing these programs and consulting with experts like Allan Lockheed in the USA we can quickly zero-in on the best combination of components to optimize power in any engine!

With the recent purchase of our new Superflow SF902 engine dyno we can quantify all our engine combinations and further development with state of the art information and accuracy.
