jbooker82 Posted October 13, 2010 Report Share Posted October 13, 2010 The power valve is like haveing a varable hight exhaust port. The higer the exhaust port the more hp you can build but it will be at a high rpm. A high exhaust port causes a poor midrange. So you have this valve the closes the exhaust port and lowers the port hight. It gives a good mirange. As the RPMs raise the valve raises, raising the exhaust port wich give a better top end. It allows an agressivly ported cylinder (Like a Drag Port) a stronger midrange. Something that isnt achievable by porting alone. The Trinity Cheeta is the most common power valve cylinder. The Cheeta cub is its baby brother with no powervalve. Quote Link to comment Share on other sites More sharing options...
fastquad02blaster Posted October 13, 2010 Report Share Posted October 13, 2010 Do some research on the RZ 350. You will learn quite a bit about powervalves and the origin of the banshee motor. I think it's the origin anyways. Quote Link to comment Share on other sites More sharing options...
