Warning! If your thinking about sending your sc to superchargerrebuild think twice!!! This is a factual testimonial from the work performed @ www.superchargerrebuild.com owner Todd manes) supercharger rebuild gone bad CHECK OUT YOUTUBE VID First off my BMW 540I was my baby, with the brembo big brake kit to bilstien sport suspension to & UUC clutch with JB racing flywheel. High boost tuning, a lot of time effort & cash went in to my BMW. Ironically my water to air cooler came a day to late...(the cooler would of stopped the impeller debris from entering and destroying my M62 engine! I had a problem with supercharger rebuilds service from the get go, when I finley got my powerdyne back from Todd the box that contained my SC unit looked like it got hit by a train. I then ordered a smaller pulley from him and they could not even get that right < sent me the same size pulley that had. He sent a 2.93 I ordered a 2.70 and his pulley had damage on the ribs , so if it was used it would tare up a good gates belt6 in no time, after refund ( in his words, “ you can barley see the damage to the ribs.” (are you kidding me Todd? if the belt ribs have any damage it will fff up your expensive drive belts. WTF? Less then a week later… It was to hot in PHX AZ to do a hot lap and do a pull on my bimmer with out a intercooler, so I drove to my cabin in higher elevations with cooler air to be safe, so I thought. I was up in the White Mountains in AZ @ 7000+ elevation on a cold evening when I did the pull which ended the whole deal.(3nd gear @ 5-6 lbs boost it went pop! I immediately took my foot of the pedal but the damage was done the metal from impeller lodged my throttle body wide open my gas pedal stayed floored. Right Then a huge explosion of aluminum blasted out my exhaust! It was all over. ( I then had the car towed 200+ mile to my shop in PHX AZ. So much for feeling safe power from cooler air. Conclusion: Due to improper fitment on the impeller shaft (impeller was improperly seated on the shaft.) The shaft spun much faster then the impeller, this caused major friction. Along with the low grade cast impeller (do not buy superchargerrebuild.com stage 3 high cfm impeller!) The shaft spun way faster then the impeller (witch should have been fixed tight to the shaft ) produced major friction (heat) This caused the core of the turbine to heat up to a level in witch the cooler air being drawn in to the impeller fins caused a catastrophic failure. The extreme temp differences from the hot core to the cold fins caused the impeller to explode! Just like pouring cold water on hot glass! The rebuild cost me near a grand , and blew up my BMW M62 engine!!! superchargerrebuild claims they custom make their bearings, if I knew that before I would of never purchased the rebuild or ther bearings. I DO KNOW THIS: If you take a cheap bearing (housings) that is designed for steel balls, take out the steel ball bearings and put in the ceramic ball bearings, You cant claim ABEC9 nor any tested RPMs. It’s a pure scam and is worse then leaving the steel bearing in the housing in witch the bearings designed for. The bearing it self is a small part of what makes a good tested bearing. Real ceramic bearing have to be designed & tested with & for the ceramic balls, thus you have many other parts like the spacers for the bearing the design of the spacers for the ceramic bearings the material, the way the housing is designed , pretty much EVERY THING!!!.
