Turbo Upgrades

This is where you will find upgraded turbochargers that make more boost and can handle higher power levels. If your stock turbos are worn, it is a perfect time to look into upgrading the factory snails with something larger.

**The turbo blanket can change color hue due to production batches ** It has not been installed or run prior. The Forge Motorsport FMTUBL4 has been specifically designed for the MINI R55-R61 Cooper S/JCW stock turbo charger. This turbo blanket is designed to isolate the radiant heat produced by the turbocharger. The stock MINI heat shield is inadequate and can result in warping the standard air scoop located in the bonnet. This design has been created to withstand the harshest of environments and proven to withstand temperatures up to 2500 °f of radiant heat which will assist in protecting and prolonging the life of engine components. Design innovation keeps the heat of the exhaust gases contained within the hot side of the turbocharger, away from the cool side and the intake path which helps reduce turbo lag and air intake temperatures resulting in more power. Please note that a turbo blanket will lose its flexibility over the first few heat cycles as the material cures, so once fitted it should not be routinely removed as this can cause damage to the blanket. It can also change color due to heat cycles.

Welcome to The Turbo Engineers' TTE940 Stage 3 Turbocharger upgrade for the BMW S58 Motor. To construct a pair of TTE940 turbos, TTE removed the original compressors and employ a far larger and more efficient billet wheel and mill the compressor cover to the optimum gap to match the new compressor profile. TTE also fitted TTE 9 blade Low-Mass turbines in the turbine housings for greater flow and lower exhaust gas temperatures at high boost and designed and fitted our upgrade bearing pack for durability. The Turbo Engineers also supply TTE upgrade turbo inlet intakes for no restrictions and ease of use. This combination gives the greatest power potential but also a fast boost response for the ultimate Plug & Play hybrid turbocharger upgrade. Race tested and approved. 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.

To construct a TTE400 N20, the folks at TTE change the original compressor and employ a far larger and more efficient billet 6+6 wheel and mill the compressor cover to the optimum gap to match the new compressor profile. Notice how they CNC mill the cover to have a smooth transition to the intake inlet, no big step to hinder airflow as you see on the competition's offerings. They replace the original exhaust turbine and CNC mill the turbine housing to install a larger 9 blade turbine for greater gas flow and lower backpressure.
