eas | VF420 Supercharger Installation - 2004 BMW e46 M3

As many of you know, david @ eas suffered from a failed rod bearing in his 2004 BMW M3. Upon further inspection, we noticed the exhaust cam bolts were also backing out - as a few reports from others have confirmed as well. Thus, a donor S54 was sourced with about 70K on the clock and quickly torn down. A fresh set of VAC's Coated Rod Bearings were installed along with new bolts on the cam gears to prevent any future issues.

Preventative maintenance is a must - normally aspirated or otherwise. After installation, a compression/leakdown test was performed and the engine given a clean bill of health, and David was back on the road. After the 1200mi break-in for the rod bearings, this M3 was able to pull a very respectable 277whp on the dyno - indicating a strong baseline for a stock engine.

VF420 Supercharger
We are firm believers in the parts we sell, and run many of them on our own BMWs. At the time with MFest V just around the corner, we decided that it would be great to install a VF420 Supercharger system and some Cool Carbon pads and hit the track.

Here is a completed shot of the install, showing the the new Vortech Compressor - which feature the Black Ceramic coating for an aggressive appearance the hood is popped open. Supercharger mounting bracket is also hard anodized for durability as well as a stealth appearance.

Some quick pics of David's M3 on LVMS @ MFest V:

Respectable numbers can be made with VF's entry level kit, and with a relatively small investment, any e46 M3 can achieve similar numbers for great fun both on and off the track.

Feel free to contact us if you should have any questions!

For those wondering, the M3 ran great at the track, very linear power delivery that was very easily controlled through the turns. Daily driving the M3 is no different than how it was before while it was stock, except with much more of a fun factor in the higher RPMs!
