Beans Diesel Air Force Milled Turbo Compressor Wheel 94-03 Ford 7.3L Powerstroke

Unfortunately, turbo surge is relatively common on the 7.3's. If you're not familiar with what turbo surge actually is, in short, if you let off the throttle suddenly while under load, its a "chugging" sound, often referred to as "barking the turbo." Most often, turbo surge is an after effect in the diesel performance industry of putting too large of a turbo on a truck. The turbo is operating on the edge of its efficiency map and when you get on the throttle hard and then let off abruptly, the turbo wants to spin backwards. This is not the cause of turbo surge on a 7.3 (having too large of a turbo). The one thing you will notice different about a 7.3 compressor wheel compared to any other compressor wheel on the market, is that the fins on the factory compressor wheel are equal length. This causes the compressor wheel to form an air bubble, for lack of a better word, when the turbo is operating at its peak. Look at any other compressor wheel and you will notice that every other fin is tall and between them is a short fin. This allows the air flowing into the compressor housing to be scooped and compressed instead of skipping over the top of the fins. The Beans Diesel Air Force Milled Compressor Wheel is designed with the proper fin heights and will not only result in more performance from your turbo diesel, deliver quicker turbo spool up, lower exhaust gas temperatures (EGT's), but it will also make turbo surge a thing of the past.
