A little late for the rest of the Story....... But better late than never as this might help somebody else in this situation......So.... After installing the Edelbrock Supercharger, I put 15,000 trouble free miles on the car...even with only 6 lbs of boost the car was a ball to drive with the added Torque........So... In July of last year we were driving to Des Moines, Iowa for the Good-Guys show......I was driving on I-80 around 80 MPH and all of a sudden I lose power steering and the engine went into Limp home mode.......WTF...... I coast over to the side of the Highway and open the hood......Here's what I see
The Pulley broke off the water pump......... Hummmm !!!!.........
I called Mark Stielow and sent him a picture and asked him if he had ever seen this before........ He asked me what car that was off of and I told him the Impala......Then he Educates me on the Edelbrock single belt drive set-up..... He explained that all the torque of turning the supercharger is transfered to the belt wrap around the water pump pulley....... Once he told me that it made perfect sense...... Then I wondered why Edelbrock didn't have any reference to this in their instructions...... So..... I go on their website and I see they are now selling a replacement pump with heavy duty bearings and a Flanged pump shaft with a bolt on Billet Pulley.....
So... I told Mark about the pump and said I ordered one..... Then he tells me the same pressure was put thru the Power Steering Pump and I should order one of the TurnOne Power Steering Pumps that are designed to absorb the pressure ..... Put all the new stuff on and I now have the confidence to drive the car across the country again........LOL
