SKU: D310-0115

All orders will include an AutoTalent window decal
Description:
 

In order to attain maximum advertised power gains these big turbos will need to be paired with DINANTRONICS Stage 4. Dinan’s intercooler to fully regulate the boost increase and deliver a polished product, the exhaust and intake is also recommended. 

The compressor wheel inside the turbocharger is increased in size allowing ~30% greater flow which enables additional boost pressures at higher engine speeds while retaining efficiency. These aren't standard rebuilds but rather brand new units with a new stock turbine custom cast and manufactured with an upgraded thrust system to ensure reliable and prolonged life. 

Benefits of the Dinan Big Turbo for the MWG N55 Engine:

  • Peak power: 428 HP @ 5500 RPM and 443 ft-lbs @ 4500 RPM and a max gain of 122 HP @ 6000 RPM and 107 ft-lbs @ 6000 RPM when coupled with other Dinan Performance upgrades (Data from F30 335i MWG w/ MPPK and automatic transmission. Other variants may produce different results).
