Message	that the compressor flow exceeds the engine flow demand. If 3071s already have surge problems, 3076s and bigger turbos will have it worse. Look at the 3071 compressor map plotted against our 3 litter engine where the engine flow falls in best case scenario, assuming 100% VE. Most of the engine flow falls to the left side of the compressor map. Below 5k rpm, boosting 1.5 bar or more, there will be in compressor surge. www.ztechz.net ICQ # 14337317
