E30 Dyno Graphs

Overview

Here's an idea I came up with while searching for information for my own engine build. A one stop page showing multiple dyno graphs of various engines in different states of tune, from standard through increased capacity to forced induction.

Please note that the results of these graphs will be unique to the individual engine being tested at the time in those conditions so there is no guarentee you'll achieve exactly the same results with the same mods. With the addition over time of more graphs I also hope that they'll be plenty of graphs for standard engines to help show how good results can still be achieved with these engines many years after they rolled off the production line.
