BMW e28 Dyno Database 

The goal of this thread is to collect as many dyno plots of various e28s in one place for future reference. This gives everyone a good database of plots for various mods, boost levels and engines. I have dug through the forum and found a good selection of plots and have included a few notes regarding each setup. These are from various users, some who no longer post here or who are inactive. If any of these dyno plots are yours and you have a more current plot you would like to include please post it and a short list of mods. Since I cannot do an extensive list of mods for each plot, it would be beneficial for that user to chime in with a post of their own plot and a list of mods. I will then remove the repeat image from this initial post. Remember, that some of the plots show uncorrected power while some show SAE or STD corrections. The type of dyno will also color the wheel horsepower number. Take each plot with a grain of salt when comparing them. The plots appear in no particular order but have been separated into forced induction and naturally aspirated categories. Enjoy and get to posting up your plots!
