Comp Cams offers a very-easy-to-use and interesting engine simulation software called CamQuest 6 that allows you to quickly create a basic engine combination that can then be tested against every catalog cam that Comp offers for that engine to estimate torque and horsepower. The simulation pulls its basic programming from the DeskTop Dyno engine simulation, which I’ve used for years with good results. This simple empty-and-fill simulation model tends to work best with normally aspirated engines, and the results are only displayed as peak horsepower and torque, along with overall power averages. I’ve used this simulation to make a decision on which camshaft to use for magazine engine buildups. I will use the cam that generates the most average power over the entire pull rather than the one that makes the most peak horsepower. Often, the best cam will do both—that’s when you know you have a winner. You can find this software and download it for free just by logging on to compcams.com. Check it out—you can’t beat the price.
