Das Race: My '97 M3/4/5

[Jake]

I'm going to add a Vanos rebuild to my winter list of fun. A bunch of us got on a GTS2 group chat on Facebook today and everyone thinks that my dyno graph is weird in the midrange - though peak HP/torque are both fine. These numbers (maybe because of my odd midrange) have my competition weight fairly low. Not bad but a bit head-scratching to me.





I may do the Dr. Vanos "stage one" kit that is just a remove-and-replace with a rebuilt unit of theirs... or maybe I'll do the Besian Systems rebuild seals. Not sure which is the better idea.
