Hey, Do you want to know how to bring these engines back into the spotlight? Well, for starters, put a great deal of info on these forums. Post pictures of the internals so that members can see the craftsmanship and factory modding (if they still do that). Next, post videos of these engines in action! Finally send motors to professional tuners such as Powerhouse, AB and RB to get professional reviews of the motors. Finally, send samples to the magazines for testing. Post the reviews on the forums and I guarantee that these motors will sell like crazy. Many racers have heard the legend of the Radical and OPS motors but have not seen or run them. Get the word out and the Radical motor will be back kick'n A@@!
