I installed an hks supercharger to my supercharger over a year ago and recently I noticed a significant loss of power. Upon inspection and removal of the supercharger, I noticed that the supercharger housing was cracked and that oil was leaking out of the supercharger. Also when the pulley was spun, the impeller didn't spin at all. what could cause something like this to happen as I only drove it about 20k km and had it professionally installed and tuned. I contacted HKS and the seller FTspeed and none of them want to tell me what can cause this and just told me to buy another supercharger.
