1) Engine Analyzer Pro v3.3 Released We've finally wrapped up the Engine Analyzer Pro v3.3. Click here for the Engine Analyzer Pro v3.3 page on our website where you can download the complete demo (button at bottom of this page), an Update Only file (much smaller) if you already have an earlier demo, or view the v3.3 Supplement PDF on all the new features in v3.3 (top of this page). Final CDs should go out the week of April 5th. Thanks for all your patience and feedback.

-------------------------------------------

2) Rotating Inertia Calculator v1.1 Released We've released a new program, the Rotating Inertia Calculator. We all know that reducing vehicle weight improves performance in most any type of racing. However, removing weight from rotating components has a bigger effect than removing weight from a non-rotating part. Other factors have a significant impact on the overall "payback", including tire size, gear ratios, where the component is located, diameter of the component, etc. The Rotating Inertia Calculator lets you estimate all these effects. Visit its webpage at for more info and to download a demo (button at bottom of this page). Cost for the complete program is $39.95.

-------------------------------------------

3) Compression Ratio Calculator Bug Fixes We've fixed a couple of bugs in the Compression Ratio Calculator, the two most notable being: Piston volume was still used in calculation even though you specified a Flat Top piston. If you clicked on 'Cancel' when exiting the program, the program would quit anyway. We've also added a "Quench" calculation, gasket thickness + deck height clearance. Click here for info on the program, and to download the latest demo (button at bottom of this page). You can also read up on recent changes in this program and most of our other programs on our Updates page, which has Readme.doc files listing recent changes and bug fixes for most all programs:
