Ratio rockers are a quick and easy way to up the power out of your engine, BUT they come at a cost. In addition to the expense of just buying them, there's the fact that they increase the stress on all the other parts in the valve train. Expect your cam lifetime to go down by a factor that is at least as large as the gain you got in horsepower. Like everything else, it's a compromise. So you get to choose which is more important to you. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
