This 2013 BMW M3 was brought into SL Autoworks (stock) to have this Supercharger Kit installed and upgraded aftermarket BE Rod Bearings and ARP Rod Bolts.
Before coming to SL Autoworks the car was bone stock with high-quality fit and finish components. This is always great because it makes for a smooth install. The owner purchased the Supercharger kit which gives a turnkey bolt-on system with approximately 181 flywheel hp increase and 94tq increase.
VF Engineering 595 Supercharger Kit:
- Vortech V3 Si Supercharger
- Larger Bosch injectors
- Cast aluminum upper intake plenum
- Air to water heat exchange
- Blow off valve
Once we got under the hood we found considerable wear on all 16 rod bearings, as expected. The factory 10W60 oil is proven to be too thick for the factory rod bearing tolerances in the S65 engine. A contributing factor to this wear is lack of ‘warm-up’ from cold starts, but primarily the clearance is the downfall.
Aftermarket BE Rod Bearings Install:
- BE brand S65 rod bearings
- BE ARP rod bolts
- New seals and gaskets
The BE rod bearings feature a coated standard size half shell and the other shell a .025mm undersized shell. This fixes the clearance issue and allows for the factory 10W60 oil.
The BE spec ARP rod bolts eliminate the torque to yield OEM bolts which provide better clamping loads.
Once everything was installed the BMW had instant, turn-key power with little to no maintenance required.
