Dinan Big Turbo - 2012-2019 BMW 'F' Chassis N55

For the racing enthusiast or those just looking for the best this is the ultimate upgrade to fully maximize the power output of your EWG N55 engine. The compressor wheel inside the turbocharger is increased in size allowing 30% greater flow thus enabling additional boost pressures at higher engine speeds while retaining efficiency. These are fully cast turbos that are manufactured to Dinan specifications along with an upgraded thrust system over the stock turbo to ensure a reliable and prolonged life. In order to attain maximum advertised power gains, these big turbos will need to be paired with the approriate Dinan tuning, as well as an upgraded intercooler (Dinan Dual Core Intercooler where applicable) to fully regulate the boost increase and deliver a polished product.

• Larger billet compressor/impeller wheel that allows ~30% greater flow over stock which then enables additional boost to be realized while retaining efficiency.
• Turbo assembly is compatible with electric wastegate vehicles only.
• Peak power w/ Stage 2 Flash (M2): 417 BHP @ 6500 RPM and 440 LB-FTs @ 3500 RPM with max gains of 48 BHP @ 4000 RPM and 64 LB-FTs @ 3000 RPM with software, turbo, and intercooler on 93 octane. Race gas options also available.
