pulley

Do any of you guys have the JET Power Flow MAF Sensor? Or the Non Stop Tuning Lightweight Crank Pulley? Both of them claim great things but I'm quite hesitant as I haven't heard of anybody installing them. BTW for us suckers in California, the Jet MAF is CARB certified. Links below...

hey people, I've posted this a few places but i assume they're dead threads. or no one likes me haha I'm think my problem sound is coming from one of the pulleys, possibly the water pump. can anyone make a guess from the description below. I've got this squealing sound coming from the engine...
