I've been doing some research on little improvements I can make when the weather gets bad here. One of them has to do with aluminum pullies. Looks like its easy enough to find the crank, jackshaft, and blower ones. I also found some threads regarding a person (or company) who once made water pump and alternator pullies, but no longer. Does a complete set of aluminum pullies exist? I only care because spinningwheels claims 12-15hp for the crank pulley alone: http://spinningwheels-sc.com/index.asp?PageAction=VIEWPROD&ProdID=130
Does that seem possible? I know the thing is heavy, but I don't fully understand rotating mass either.
I also searched for aluminum tensioner pullies on the board as well as Google. Looks like some have tried one-off or even pullies made for other vehicles that happen to be wide enough and have available bearings to fit. Anyone manufacture bolt-on ones?
I think during winter I will get new belts, stronger tensioner springs, and continue my search for lightweight pullies. I was also going to ask about overdriving the early M90, but I think I'm just going to find a '94/5 or better and throw a 5% jackshaft pulley on it. Trying to make my n/a motor last a while under boost anyways.
