SCCA F500

     WPT has been building Rotax racing engines since 1978 It was a natural for us to get involved if Formula 500 as preparing, tuning and clutching, we bring a lot to the table.

     In Snowmobile racing, there is also classes that use a Y pipe just like F500. WPT engines have won the World Championships in this class 8 times. We brought this experience to develop a tuned pipe for the SCCA F500 cars. In 2006, our new pipe set on the pole at more than half the races that year. A number of victories were also scored. This pipe is available with our unique stinger coming out the top of the pipe. You can see easily who has our products.

     If you are really a player this is a must. We take the engine completely apart and reassemble with a few little detail tricks here and there. Even a new engine does not come from the factory with a crank the meets our standards. We start by straitening the crank. Care full base gasket choice to put the ports and head where we want it to match the Pipe we recommend.

     Racers may come to our facility or ship engines to the WPT for Dyno for tuning and evaluation of many engines in a days time or fine tune a given engine. See which of your engines is better and tune the best performance out of each one. Find the correct Rpm range, Jetting, Timing and even Spark Plugs, are things you can now verify with solid data, no longer just opinion.

     WPT uses the most advanced computer engine simulation software in the world. The same software that some of the OEM’s use. Optimum Power Technology is beyond the capabilities of performance shops and uses the true science of an engine in every detail. Use it or get beat by it.
