Thread: My 2008 BMW 135...

  1. #1 Default My 2008 BMW 135... 
    Okay, my car has a short story to it. I bought my car from a gentleman by the name of George Mehalick, owner of MadnessMotorworks in Portland, OR. It had 3800 miles and had been featured in European Car magazine and EuroTuner. I removed all his mods and started fresh. I left the short shift kit and BMW Performance electronic steering wheel.

    And now I'm running a COBB base....with a Mr. BrenTuning custom tune.

    2008 BMW 135I Mods list:

    COBB custom BrenTuning tune: 426whp/470wtq
    BMS dual cone intakes
    Forge Motorsports Diverter valves
    MadnessMotorworks Intercooler
    Raceland Downpipes
    3" one-off custom midpipe
    Berk rear axle-back street performance exhaust
    Kerscher KM2 front bumper with Kerscher Carbon Fiber front lip
    BMW rear Carbon Fiber spoiler
    2012 European BMW headlights
    19" Alufelgen SF71 wheels wrapped in Michelin Pilot Super Sport tires
    Dinan performance springs .5" drop
    H&R sport cup kit struts
    BMW Group N M3 rear subframe bushings
    Hotchkis 32mm front sway bar
    Turner Motorsport adjustable endlinks
    UUC motorworks customRK6A-L adjustable shift knob
    BMW short shift kit
    Bimmian racing pedal set
    BMW V1 electronic performance steering wheel
    Koala Motorsports rear diff

    Here's the latest dyno video. Let me say this regardless of what folks think about the different dynos out there, the gains are what I look for.
    I had 388whp up until 2 weeks ago.

    Holy shit. I remember seeing a base 335i two years ago dyno like 220whp and ignored that engine until now. It's damn potential.

    So all it needs are tune, intakes, downpipes and diverter valves to go over 400whp?

    It's funny, because now I giggle a bit every time I step on it.

    220whp? Something was wrong seriously with that 335. Mine made somewhere around 308whp when I 1st got it, with no mods.

    thought they made more than that stock. when it came out people were talking about it being underrated not to best the E46 M3. But yeah they have some potential, but also some potential problems with the high pressure fuel pump I believe.

    I need to bring my 1er to Bren to get a custom cobb tune. Now that I have new plugs, and turbos and a FMIC i should be good to go.

    The N54 motor is really starting to shine with the aftermarket. 400whp and 450wtq is easy with just bolt ons. A few people are making 450whp with meth injection, and 500whp with upgraded turbos.

    The new single turbo N54 is making 650rwhp with bolt on support mods.

    Most of the fuel pump problems have been worked out, along with an extended warranty.

    A stock 335i with just an intake and tune can make 350whp, 360wtq.

    N55?

    650whp on bolt ons? I'd be curious to see how long that lasts, that would make me kind of nervous. Not many engines can pull that off.

    No the N54 is an iron block. Vishnu tunings car has been running 650whp for a couple thousand miles with no problems so far. Engine had 80k on it when they started too.

    so much potential in that motor, its stuff like this that makes me want to get an E92 335i M-Sport. it would be more comfortable to drive than the e46 m3, and have more creature comforts and technology upgrades, as well as way more usable power for the DD commute.
