I was just wondering just how much difference does a 38R turbo really make on a late model 7.3L engine in terms of power, acceleration, EGTs, and smoke. Does it really give you more power? Without first spooling my turbo will it make my acceleration faster? How much will it really lower my EGTs? Does it help with reducing smoke at all? Also how much boost can the turbo really make? Websites say 40psi is the most but can it go higher then that or does it come in short? I just want to see what people are really seeing with the turbo before I spend all this money on it. Thanks for you the help!
