That is at all four wheels on a 2016 W212 E63 AMG S. Additionally, with 91 octane pump fuel at 20 psi with supplemental methanol injection. The car also has the Weistec 722.9 Bulletproof transmission upgrade:
That is a ton of power and torque and keep in mind this is not with the turbochargers turned up as this M157 is stock internally. There will be a W.5 package with forged internals which of course have been available from Weistec since last year.
What will this turbo upgrade do with a built M157 and the turbos cranked up? Well, we will soon find out but expecting 1000+ is within reason.
As for performance the W.4 was measured at 60-130 in 6.153 seconds:
We will have to wait and see on the 1/4 mile times.
Overall, Weistec has done a ton of testing on the W.4 upgrade and you can rest assured that it delivers as advertised: http://weistec.com/m157-w-4-package.html
M157 W.4 Package
The M157 W.4 package is the package for customers seeking the pinnacle of performance and refinement. At the core of the M157 W.4 Package is the M157 W.4 Turbo Upgrade. Taking a giant leap ahead of all other available upgrades, the M157 W.4 Turbochargers completely replace the factory units. They are ball bearing, featuring CNC machined billet aluminum compressor wheels capable of flowing 65lb/min.
To feed these monster turbochargers, completely new airboxes and intake tubes are included. The Weistec Turbo-Folds provide significantly increased flow of exhaust gasses compared to the stock turbo-fold. The Weistec M157 True Downpipes perfectly mate up to the M157 W.4 Turbochargers to ensure minimal restriction once the exhaust gasses have gone through the turbine.
An Engineered Solution
The W.4 Turbochargers are the most capable production turbochargers available for the M157 engine. The W.4 Turbocharger Package which includes our M157 ASV/Water-Methanol Injection System is capable of producing 1000+ crank horsepower (820~850HP at the wheels on a Dynojet Dyno) on 91 octane pump gas. What’s equally impressive is that these numbers are achieved at only 20psi, and 20 psi is only the beginning.
The goal of the W.4 Turbocharger Package was to have a complete package that provides amazing gains in power and performance, but does not require race gas, or an iced down intercooler system. Something that can be daily driven, filled up at any gas station, and is within power capacity of the factory engine internals.
Control = Reliability
While the M157 engine is a very robust engine in factory form, we have seen a couple weak leaks at extreme power levels. The most common is a bent connecting rod. If the engine is producing a sustained 1000 lb-ft of torque (820-850 lb-ft at the wheels) or more, all it takes is one knock event to bend a rod. This was taken into consideration with the ECU tuning for the W.4 Power Package as they can make far more power and torque than a stock M157 engine can handle. Boost is controlled and tapered up to the peak of 20psi as RPM’s increase. This creates a broad torque curve that remains under 800 lb-ft (at the wheels) while allowing power to continually increase towards redline, minimizing stress on the rods as well as the rest of the drivetrain. With a fully built M157 and other supporting upgrades, expect to see significantly higher power numbers as the Turbochargers can flow enough air volume for 1400+ crank horsepower!
