Message	Compressor surge is when the output of the turbo exceeds the ability of the engine flow demand. Compressor surge can damage compressor wheel. Anti-surge compressor housing can help but is usually available for bigger turbos. You have to plug the engine flow into the compressor map to determine the surge. In the case of 3071, the left most curve is the surge line. By plugging the engine flow, it shows the surge will happen during which rpm and which boost pressure. www.ztechz.net ICQ # 14337317
