To construct a pair of TTE850 VTG we change the original back plates for Gen 2 and Gen 2 compressor covers and employ a far larger and more efficient billet compressor wheel and mill the newer Gen 2 compressor covers to the optimum gap to match the new compressor profile. The turbines are original but with clipping of the blades for greater flow and lower exhaust gas temperatures and also removing some mass to help improve response and we also CNC mill the exhaust housings to improve flow. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEquilibrium\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003ePrecisely balancing our 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 using our single parts machine, then components are assembled, and then the CHRA are dynamically balanced, but this time depending on the 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Highlights:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOriginal BWTS VTG turbocharger as the base part for new \u003c\/li\u003e\n\u003cli\u003eVery early response\u003c\/li\u003e\n\u003cli\u003eBillet Milled TTE compressors 6+6 BLADE 54.5mm Inlet\u003c\/li\u003e\n\u003cli\u003eOEM GEN 2 TURBO S backplates\u003c\/li\u003e\n\u003cli\u003eHigh Flow Clipped Turbines\u003c\/li\u003e\n\u003cli\u003eCNC machined Turbine housings \u003c\/li\u003e\n\u003cli\u003eNew supplied CNC OEM GEN 2 TURBO S compressor housings \u003c\/li\u003e\n\u003cli\u003eGEN 2 Breathers\u003c\/li\u003e\n\u003cli\u003eGEN 2 Actuator rods\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation only \u003c\/strong\u003e\u003cstrong\u003ewith DO88 upgrade silicone turbo intakes\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e850PS+ Proven\u003c\/li\u003e\n\u003cli\u003eSoftware recalibration is required \u003c\/li\u003e\n\u003cli\u003eProven TheTurboEngineers Quality\u003c\/li\u003e\n\u003cli\u003eSingle parts finely balanced then components assembled and core high-speed VSR balanced\u003c\/li\u003e\n\u003cli\u003eSupplied with a balance test result document\u003c\/li\u003e\n\u003cli\u003e\u003ca title=\"1 YEAR TTE TROUBLE-FREE WARRANTY\" href=\"https:\/\/tteglobal.com\/custom\/index\/sCustom\/55\" target=\"_blank\"\u003e1 YEAR TTE TROUBLE-FREE WARRANTY\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eMade in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"TTE","offers":[{"title":"Default Title","offer_id":50524073427137,"sku":"TTE10402","price":11385.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/TTE850-VTG-2fvz0T1cN9pF41.jpg?v=1787605583","url":"https:\/\/www.urotuning.com\/products\/tte-850-5546-vtg-porsche-991-1-turbo-upgrade-turbochargers","provider":"UroTuning","version":"1.0","type":"link"}
