    Here's a rolling race after the engine rebuilt. I raced a E34 3.0 Stroker, high compression engine, 4.0 TB, Ebay headers, tuned 7200 rpm, weight reduction (no rear bumper, no rear seats), 3.23 diff, S52 cams

    Next i will visit the dyno to check out the AFR,HP and Torque curves.

    Lol I love that you get your baseline comparisons via Georgian highway drag racing and then do dyno checks just to see. Really provides a different look at modifications and makes sense as to why the taller differential (that all of us love for low speed driving) didn't do anything for you.

    ===============UPDATE==================

    I ran againt a Skyline 3.5 A/T 232WHP, before i had done head gasket job it was a draw or sometimes i would outrun him by a bit. With the new rebuilt engine the Skyline beat me hard, the difference was about 3-4 car in between him and me I had my friend follow us and he noticed smoke coming from my exhaust when shifted or hit high rpm, then i checked when i stopped the car hit the limiter at 7000 rpm and black smokes came. My AFR is 100% rich, I though i had leaks in my vacuum system i ran a leak tests but it is fine, i also checked the fuel rack pressure it is 3.8 bars which is the same as it used to be. I know everyone reports 3.5 bars but my fuel pump isn't oem and pulls much more pressure that should be the reason for being higher then the oem. I also ran diagnostics BMW Scanner, INPA, Rheingold but the isn't a problem or error. So the only option is to check my AFR and run some tests with the logger attached to the exhaust which i am planning on doing the next weekend at a local tuner where i tuned my car, George Gelashvili @ https://www.facebook.com/GelashviliPerformance/

    First we will check the logs and then retune it, i will post the results.
