To produce a TTE300 K04 upgrade turbocharger TTE uses a much larger BorgWarner 2280 compressor wheel, chosen because it is highly efficient and light in weight at 36grams for fast response. This compressor also features BorgWarner Extended tip technology giving a compressor map that's very wide, creating extremely high flow for comparative size. Then CNC Re-Profile the compressor cover to optimize a tight tolerance and finish to ensure maximum compressor efficiency is given.


Precisely balanced turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes, 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 TTE's in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.
