The WGM540 is our very latest hybrid performance upgrade turbocharger based on the Original turbocharger for the BMW B58 inline-six-cylinder turbocharged engine. Superfast spool and response with extra power. We feel this is the best-performing 500-540HP pump fuel hybrid turbo

 Engineered & Enhanced 

To construct the WGM540 Stage 1 Hybrid Turbocharger we change the original compressor and employ a far larger and more efficient billet wheel with extended tip technology, changing the Trim A/R and mill the compressor cover to the optimum gap to match the new compressor profile.  We change the Original exhaust turbine for a larger 9 blade high-flow item to lower EGT and raise the power potential but maintain a great boost response profile, this also has a similar effect to changing the A/R ratio, in essence improving exhaust turbine capabilities without enlarging the exhaust turbine


Precisely balancing our turbochargers is a key critical factor to becoming a reliable upgrade unit as power is pointless without reliability. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial-numbered balance test result document.
