Have you ever wondered if the cam you're installing is actually making horsepower? How about the ported and polished cylinder head? Or the larger valves you've installed? Wouldn't it be great to know if these performance components would actually make a difference in engine performance before you fork over your hard-earned money?

Well, now you can with ProRacing's intuitive Sport Compact DynoSim software. You can virtually build any four-cycle engine from a stock 1.5-liter single-cam Honda to a fully built monster 2JZ pumping out 1.000 hp. Just plug in all the specifications you want in an engine and the software will calculate the amount of horsepower the engine should generate. It will even print out a dyno graph of the engine's expected power curve.

Just follow the instructions and choose the short block from the hundreds of different car manufacturers. You can build a 4-, 6-, 8- , 10- or even a 12-cylinder motor. The user-friendly software allows desktop enthusiasts to test different cams on the virtual engine, intake and exhaust valve diameters, cylinder head CFM, compression ratio, intake manifold, turbocharger, supercharger or nitrous. The Windows-based software is easy to use.

The DynoSim software will also calculate compression ratios, airflow and cam profiles. Once the engine is complete the software is also capable of performing thousands of simulations in Pro Iterator to determine what degree the cam(s) should be dialed in for the best horsepower or torque outputs. It will even model VTEC variable valve timing on B-series DOHC VTEC heads.

The software retails for about $200, but considering the time and money you will save from testing a certain cam profile or ported and polished cylinder head, that is money well spent.
