Turbosmart BOV Kompact EM Dual Port VR11 - 2016-2018 BMW N55 M2 & X4 M40i
The Turbosmart Kompact EM Dual Port VR11 is an electronic blow off valve designed as a direct replacement for the factory diverter valve on BMW N55 turbo engines in 2016-2018 M2 and X4 M40i models. It delivers precise boost pressure control with solenoid actuation for rapid response during shifts and spool. Dual port design supports both atmospheric venting and recirculation for versatile tuning setups.
Key Features
- Dual Port Technology: Single valve body with separate ports for vent-to-atmosphere or full recirculation, enabling easy tuning changes without swapping parts
- Electronic Solenoid Actuation: PWM-controlled solenoid responds in milliseconds to ECU signals, holding boost accurately up to 30 psi on N55 turbos
- VR11 Piston Design: Large diameter piston optimized for N55 turbo flow rates, prevents compressor surge and maintains consistent performance
- Billet 6061 Aluminum Construction: CNC-machined housing withstands high pressures and heat, weighing only 1.1 lbs for minimal impact on engine bay balance
- Plug and Play Installation: Direct OEM replacement with included O-rings, springs, and wiring harness for 2016-2018 BMW M2 and X4 M40i
Product Notes
- Requires ECU remap or boost controller integration for solenoid operation using factory MAP sensor signal
- Includes multiple spring options for base pressure adjustment from 5-25 psi
- Secure packaging prevents damage during transit
Installation Notes
- Professional installation recommended.
- Disconnect battery and relieve turbo pressure before removal of OEM valve
- Compatible with factory charge pipe and intercooler piping, no bracket modifications needed

Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
