  • I take the BMW 128i back to Brainerd International Raceway for another track weekend trying to get a sub 100 second standing start lap on the 2.3 mile road course. I added a wing and splitter this time in hopes to lower my lap times!

    Great 128i video series, thanks for making these. I'm building my 128i in a very similar manor. Do you have M3 Control arms? spherical balls in tension rods? and what sway bars?

    Ever thought about adding custom itb’s? I’ve seen one guy do it on UA-cam 🤔

      Yes. Hoping I get into the beta testing of 22rpd's trumpet itb setup.

    What’s the exhaust set up? I have a 128i as well, I love your build

      Straight pipe with only a vibrant ultra quiet resonator. It's wayy too loud, but I like the sound it produces.

    Did the 15w-50 get rid of puff of smoke you were seeing on restarts at the track? Did you notice any oil consumption with that over the course of the day?

    • @KrebsbachRacing
      @KrebsbachRacing  8 місяців тому +1

      It helped quite a bit, but did not eliminate it completely. No way to measure oil consumption because of the stupid electronic dipstick.

    • @spidertri723
      @spidertri723 8 місяців тому

      I cant stand that about the e-dipstick, I was just wondering if you noticed the oil level was lower after you left the track while driving on the street?

    So the 1.3 seconds was all from the aero?

    • @KrebsbachRacing
      @KrebsbachRacing  11 місяців тому +1

      Yes sir. More like 2 seconds I would say. I have had similar results with the Evo back in the day. About 2-2.5 seconds quicker with a splitter and wing.

      It's either my gopro microphone or the wind. It wasn't breaking up at all.

    If it has the plastic valve cover, it's time to replace it if you haven't.
