Does anyone who runs a powerdyne blower have a low whining/rush of air sound that comes from their blower when the temperature gets hot. My powerdyne makes this noise and seems to loose a lot of power after i have been running the car for a while. The blower runs fine when the temp is cool, just not whn hot. Is this the bearings beginning to go. The head unit has only 2000 miles on it. It is fitted with the 6psi pulley and always has been. If any one has heard of this please let me know.
