BMW 135i – FBO Stock Turbo Dyno Results (N54)

Late Model Throttle was hosting a dyno day at their shop in Waukesha, Wisconsin. Knowing that there would be a DynoJet and some cool cars, I decided to sign up!

The car was strapped on and put down 448whp and 501wtq with SAE correction. However, all of the N54 guys use STD correction and that converts to about 468whp and 523wtq!

BMW 135i or 335i Exhaust with MHD Burble Option

With MHD’s latest release of the “burble” exhaust option, I had to try it out. You only need a few things to make this happen.

Simply download the app, plug the flashing cable into the car and connect the OTG cable to the tablet. Then you can flash a map with your desired burble settings.

I have the burble option set to full aggressive. I have catless downpipes and a full catless exhaust with only one muffler. Take a listen… Continue reading BMW 135i or 335i Exhaust with MHD Burble Option

BMW 135i (FBO) – 1/2 Mile Trap Speed & Races

As some of you know, I was at the NoFlyZone Midwest event this past weekend. Got almost 25 passes in. The first day was rained out, but we got a few solo runs. Going 146mph in the rain is… interesting.

The weather on the second day was much better and I was able to clock a 156 MPH run!

Tapping Intake Manifold for Larger Vacuum Line (N54 – TiAL BOV)

Since I had to remove my intake manifold while walnut blasting my intake valves, I decided it was the perfect time to tap the manifold for a larger vacuum line. TiAL recommends that their blow off valves be connected to 1/4″ vacuum line, not the small factory 1/8″ vacuum line. This is crucial on modified BMW 135i or 335i.

You will need the following parts:

Once you have all of the parts, it’s a pretty straightforward procedure. First, cap off the existing port with a vacuum nipple and a zip tie. I like to leave this nipple untouched in case I were to ever go back to stock, then I can just plug the larger port we’re about to create.

Capped OEM Port

Next you’ll want to find the flat surface next to the old nipple. Then you’ll start drilling a hole with a small drill bit and eventually work your way up to a 1/4″ bit or until the tap can thread into the hole.

Drill New Hole

Now you’ll use the tap tool to thread the plastic to accept the fitting. Run this tap into the hole until you can thread the fitting in.

Tap New Hole

Grab the fitting and wrap some teflon tape around the threads. Then carefully thread it in until it is nice and tight.

Tape and Thread

Lastly, you’ll bust out the epoxy and coat the outside so it won’t leak.

Add Epoxy

Vacuum or blow out any plastic shavings that are left in the intake manifold and reinstall. Now you’ll grab your new 1/4″ vacuum hose and connect  it from the blow off valve to your larger port for ideal operation.

BMW 135i – LUX H8 Angel Eye Upgrade

After owning my 1-series for over a year, I finally got sick of the halogen angel eye bulbs. I previously coded their voltage intensity up higher to make them brighter, but I still didn’t like the warm color.

So, I decided to buy myself an early Christmas present! LUX was running a sale, so I grabbed a pair of their latest and greatest angel eyes. Their H8 angel eyes advertised a pure white 7000k temperature with extreme brightness. Perfect!

LUX H8 Angel Eyes

I received them a few days after ordering and wanted to install them right away. All I had to do was pop the rear headlight covers off. They can be finicky, but you’ll figure it out. After the cover was off, I twisted the old bulbs out. Next, I inserted the new bulb and tucked the power supply box out of the way. Drum roll please…

BMW 135i – Rieger Rear Diffuser Install

I finally got around to installing these two cosmetic parts that have been sitting in my garage. I bought the Rieger diffuser used and the carbon fiber hydrodip was fading. Time to get to work!

Rieger DiffuserSanded it down with some high-grit sandpaper and setup a ghetto booth in the shop’s bathroom.

BMW 135i – Serpentine Belt Issues and Fix (N54)

A few weeks ago the car started making a squeaking noise. So, I popped the hood and started taking a video. Here is what I found:

As soon as I noticed the shredding serpentine belt, I drove home and parked the car. Ordered a new belt and tensioner, along with oil filter housing gaskets (#1 & #2) because mine were leaking. Once the parts arrived, I installed everything. Here is a picture of the OFH gaskets going in, what a mess…

Obligatory picture of the shredded belt:
