Mercedes ML63 AMG Biturbo (2012on) – RENNtech Stage 1 Turbo Upgrade Package
Mercedes made the latest generation ofĀ M157 biturbo engines seriously fast right out of the box. Challenge acceptedā¦ā¦.
TheyĀ took the latest generation of M157 biturbo engines and spent months testing and developingĀ their line of performance turbos.
They start with a set of motorsport derived ball bearing turbochargers from Garrett, one of the most respected turbo manufactures in the industry whose products offer rugged service life and OEM daily driver reliability. Using this platform as a foundation,Ā they put in a lot of work toĀ adapt these turbos toĀ their specific application.
The lightweight forged billet 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 coupled with less rolling resistance from the ball bearing cartridge compensates for turbo lag despite being a functionally larger turbo. The cartridge supportingĀ shaft is alsoĀ bothĀ larger and strongerĀ designed to handle theĀ larger wheels and added power.Ā ThisĀ entire cartridge is thenĀ 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 RENNtechĀ turbo package making an incredibleĀ 790 HPĀ andĀ 840 TQĀ at the crank!
More power isnāt 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’sĀ and a lighter rotating mass. In addition,Ā their turbo upgrade kit includes new high quality lines and fittings wrapped in heat resistant sleeves with every detailed piece manufactured and tested in-house to ensure years of 100% trouble-free and leak proof operation. These lines are made specifically to adapt toĀ their turbos as this isnāt just an OEM unit 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 63 series M157 biturbo!
