2018+ Mercedes C190 AMG GT C 4.0L V8 BiTurbo M178 RENNtech Stage II Turbo Upgrade (PKG.09.178.2012)

The Mercedes GT is the second Mercedes Benz vehicle fully developed by AMG, the company’s Affalterbach based performance division and long fabled engine builder. The resulting vehicle is nothing short of spectacular and the 4.0L V8 BiTurbo engine within is an incredible platform to build performance upon.  RENNtech lightweight forged billet turbo wheels feature a dramatically larger than stock impeller (inlet side) and an increase in the turbine trim (exhaust side). This combination of high quality, light weight components compensates for turbo lag despite being a functionally larger turbo. The cartridge supporting shaft is also both larger and stronger designed to handle the larger wheels and additional power. This entire cartridge is then fine balanced as a complete assembly to compensate for these increases. The impeller and turbine housings are then precision CNC machined and flow tested in-house to fit the larger internal cartridge. The end result is nothing short of spectacular with the RENNtech turbo package gaining up to +186 hp and +111 lb-ft. More power isn’t the only performance benefit as our turbos spool quicker, offer a more responsive throttle and immediate power delivery thanks to a reduction in exhaust back pressure, rolling resistance, higher RPM's and a lighter rotating mass. In addition, our turbo upgrade kit functions with the OEM oil and coolant lines. This isn’t just an OEM turbo charger with machined internals; but a dramatically larger, more powerful turbocharger that blows away anything else on the market! The RENNtech performance turbo upgrade is truly the ultimate upgrade for your AMG GT C.   Key Features: The RENNtech Stage II Turbo Upgrade comes with an RENNtech ECU Upgrade and the RENNtech Fuel System Upgrade. Larger impeller (inlet) and turbine (exhaust) cartridge Cartridge shaft is larger and stronger to support larger wheels Entire cartridge is fine balanced as an assembly Lightweight forged billet wheels Less rolling resistance offers quicker spooling Virtually no lag with impressive throttle response Precision machined impeller and turbine housings Up to 761 HP and 632 TQ @ crank     Notes: This Turbo Upgrade requires an additional core charge, which will be credited upon return of OEM turbo core to RENNtech We have found the new M178 engine stock performance numbers vary from the baseline figures claimed by Mercedes Benz. We typically see higher baseline numbers than claimed by the factory. Numbers will be dependent on conditions and fuel quality. Power gains are calculated with stock numbers measured by RENNtech To reach the maximum power level, RENNtech downpipes, BOV adapters and high-flow air filters are required. Our numbers will be dependend on conditions and fuel quality. 93+ Octane gasoline is mandatory with this Performance Package. States known for poor fuel quality have to be supplied with a lower power setup.   Performance Numbers Overview     AMG GT C (MY2018+ | C190 | M178 | 4.0L V8 BiTurbo) Stock Performance (at crank):   Rated by Mercedes-Benz:      550 HP @ 6,250rpm; 502 LB-FT @ 1,750-4,750rpm Rated by RENNtech:               575 HP @ 6,250rpm; 521 LB-FT @ 3,850-5,400rpm Note: Mercedes M157 engine performance when measured, obtains higher power numbers than rated from factory.         AMG GT C (C190 | M178 | 4.0L V8 BiTurbo) Modified Performance (at crank):   Rated by RENNtech:              761 HP @ 6,800rpm; 632 LB-FT @ 5,600rpm                                                     670 whp @ 6,800rpm; 556 wtq @ 5,600rpm

His vast experience comes from 12 years spent at AMG Germany before serving as the North American division’s Technical Director. Prior to the tuning company’s merger with Mercedes-Benz in 1999, by the request of AMG Germany, Feyhl branched out on his own to start RENNtech and service the existing AMG North America customers. Performance without compromise. This is the foundation upon which we have built our reputation. Established in 1989 by Hartmut Feyhl, RENNtech has evolved and grown from servicing AMG’s customers into the foremost authority on tuning and customizing AMGs and Mercedes-Benz. RENNtech also offers tuning solutions for Porsche, Audi and Bentley vehicles, along with other European luxury cars. Over the years, we have developed high-performance products for virtually all Mercedes-Benz AMG vehicles. Some of the most notable among these are the 200 mph RENNtech E7.4RS (which claimed ‘Fastest Sedan in the World’ honors by Car and Driver Magazine in 1996) and the more recent 945 LB-FT 5.5L V8 Biturbo RENNtech R3+ Monster. Each of these vehicles are just a sampling of what RENNtech has achieved, featuring extreme performance, upgraded aesthetics and a fit and finish that rivals factory vehicles. We design, engineer and manufacture our proprietary line of tuning products in-house at our facility which features a full fabrication and machine shop with CNC and rapid prototyping capabilities; in-house performance dynos, complete engine management and software tuning capabilities along with a complete service/repair/installation facility and a full-time design, engineering and sales staff.
