I suggested reading the link ''before'' adding a dash of hydrazine. Actually, young hotrodders are so similar to us old guys. I was no different and wanted the biggest bang for the buck,,, albeit, I paid dearly in lunched engines and other failed components, but the price was worth the knowledge gained,,, it's getting passed on to the next generation that will try ''experimental chemistry'' and it's benefits and consequences,,, you are right though,,, playing with hydrazine is playing with with fire. :-) Peter
