Cam Analyzer v3.8 (Windows 98/Me/XP/NT/2000/Vista)

The Cam Analyzer is software for your personal computer to record and analyze cam lift data from dial indicator and degree wheel measurements. Once this data is in the computer, you can check the cam profile for acceleration rates, lobe centers, duration at .050", etc. Now you can see if the cam you just installed matches the cam grinder's specs. No doubt you've seen the advertisements for "computerized cam checking" systems for $3000 or more. Although these systems are faster and can be more precise, you can perform most of the same analysis with the Cam Analyzer for a small fraction of the cost.

The Cam Analyzer also makes Cam Dr (tm), Comp Cams, and S96 files which can be used in our Engine Analyzer 'Pro' for detailed engine performance and valve train dynamics simulations based on your cam's actual profile. In addition, v2.0 lets you input and analyze computerized cam files for comparison [Cam Dr, Cam Pro Plus (tm), S-96 (tm), Andrews (tm), Comp Cams(tm), Dr Doctor (tm)], or generate cam files based on simple specs like centerline, duration, tappet lift, etc.

Download the file, then just double click on it (though Explore or File Manager) to setup. Program will run in Demo mode for free. If you like it, call Performance Trends with credit card information to purchase for $119.95.

Important:  The Cam Test Stand with electronic sensors for the Cam Analyzer lets you measure all lobes on your cam in under 5 minutes with very high accuracy.  This latest Cam Analyzer v3.8 Installer.exe demo shows files measured on our new Cam Test Stand.  Click here for Cam Test Stand info.
