I have a powerdyne on my 92 GT. I admit I do love it, but the vortechs are superior. The powerdyne is so quiet people will never suspect you have a blower. That's the strong point. The weak point is the internal belt can break. I believe they cleared their problem up. The old blowers used to have an internal tensioner, and it would seize up and the cut the belt in half. Mine did and I replaced it. Cost $60 and 6 hrs. of my time. A good thing is the simplicity of the blower. just a fan with a belt. No gears, no oil. If i had to do it over again, I would buy an A-trim vortech. Easily upgraded to 10#'s and sounds awesome. I personally love the blower whine. Get a VORTECH!!!!
