BMW N54 FMIC Upgrade: VRSF 7.5″ Race Intercooler

After installing my new fuel system and turning up the boost on my MMP Stage 3 turbos, I started to notice some really bad heat soak in my logs. Guessing that the car is around 600-650whp at 28PSI, I could see that my standard VRSF 7″ Street intercooler was no longer keeping up. It did a great job on my stock turbos, but I needed something a little bigger.

After doing some research, I found the VRSF 7.5″ Race intercooler. Judging by its size and efficiency ratings, it seemed like the perfect intercooler for my power goal of 700whp. I ordered it right away to help cool things down a bit. Four days later it showed up, very nicely packaged.

BMW N54 Clutch Upgrade: SPEC Stage 3+ with MFactory SMFW

If you’ve been following my website, you probably read my detailed post about installing a 335is/550i clutch after my OEM clutch wore out. However, with MMP Stage 3 turbos on the way, I knew the 335is clutch wouldn’t hold as I turned up the boost. With a goal of 700whp, I decided to replace it with a SPEC Stage 3+ clutch and retain my MFactory single mass flywheel.

SPEC Stage 3+ Clutch

Since I just installed an MFactory SMFW about 20k miles ago, I decided to reuse it because I knew it was in good condition.  All I had to do was purchase a SPEC Stage 3+ clutch with OEM or MFactory flywheel configuration so it would mate up properly. If I didn’t already have the MFactory flywheel, I probably would’ve bought a SPEC flywheel to go with the clutch. However, I’d rather save some money when possible!

Since the transmission was going to be removed, I wanted to refresh a few things at the same time. I noticed my shifter developed some side-to-side slop so I decided to upgrade the bushings. The car has almost 120k miles and still has the OEM transmission mounts, so I knew those could be replaced. I’ve also never servied the rear differential and noticed it was seeping a tiny bit of fluid. Might as well replace the rear pinion seal and flush/refill the fluid!

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 – 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…
