Supercharged BMW e46 M3 - engine build (updated 24/09/17)
It’s time this M3 had an engine to cope with the supercharger.
The stock engine unfortunately suffered a failure, has been recovered to us and now we will begin planning and building an engine to take the boost!
Keep checking back for the latest updates…
25/02/16 – Recovery of car – planning begins!
26/02/16 – Engine is out!
We didn’t waste any time; the M3 engine is out and ready to be stripped. We will inspect internal damage and prepare for the build. When the car is being built back up we will be tidying up the car in general including fixing other minor faults.
Now the car is in the hands of Perfect Touch it will be looked after, ready to win medals…
02/03/16 – Detonation!
We have had a look at the stripped down engine and can show you what has gone wrong. Essentially the water injection system that was fitted to the intake as part of the Supercharging has failed and the cylinder has become too hot causing the fuel to ignite before it is sparked by the spark-plug. You can see some of the damage this has caused to the top of the piston in the picture below.
We have an update on the progress of the BMW M3 E46 supercharged build. The engine components are starting to arrive, some of which you can see in the pictures below – rods, crankshaft, pistons, injectors and Schrick cams. We are also discussing other plans with the client including engine management and transmission changes. Watch this space…
