New TTE550 N55 Turbocharger Upgrade

Product Details

The TTE550 for the N55 motor. Still keeping the original turbocharger the compressor wheel is exchanged for a TTE milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, The Turbo Engineers change the original exhaust turbine for a far larger but very lightweight 9-blade TTE-designed turbine for lower exhaust gas backpressure giving greater performance, yet still giving a good spool response.

The Turbo Engineers also fitted a TTE motorsport upgrade bearing system for durability.

Equilibrium

Precisely balancing the turbochargers is a key critical factor to becoming a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequently, great care is taken with all TTE turbochargers to achieving balance standards. Firstly, parts are balanced at slow speeds up to 2800RPM in multiple planes using a single parts machine, then components are assembled and the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using an 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.
