    • Here is a pair of 800+ all wheel horsepower M157's - 2015 W212 E63 S and C218 CLS63 S with upgraded turbos

      800+ horsepower to all four wheels is pretty much the norm now for M157's with upgraded turbochargers. These two AMG's both have turbo upgrades although from different sources.

      Let's look at the E63 AMG S first:


      799.45 to the wheels but let's just be nice and round to 800. This output is achieved with AMS turbochargers, AMS airboxes, Weistec charge pipes, an AMS upgraded transmission, and a meth kit. Precision Tuning ties it all together.

      Now onto the CLS63 AMG S which has Forced Performance turbochargers. It is on the stock transmission so the 847 wheel horsepower tune (wish we had the full graph with the torque) will likely be dialed down. Still, impressive peak figures on the stock motor and transmission:


      Both cars are running methanol to hit these figures and that is important to note. It is also important to note that ~800 horsepower to the wheels is regularly hit with M157's these days. The platform is doing well.

        Yes let's have some performance data. Also still curious as to how much the stock transmission can reliably take over time. Dialling it back down to 700-750 whp would still make for an amazing package. Now someone just need to jump on a SL63.

        Well it's not like they are my cars or that the owners have to take them to the track.

        I'd like to see these run as well though. This tuner has an E63 running well into the 10's on the stock turbos: http://www.benzboost.com/content.php...n-the-1-4-mile

        How much power and torque will both cars make on pump 93 unleaded, without the methanol kit?

        +1, I want to know that too. Are these tunes dyno glory run tunes or are they street 93 tunes that are just running meth to gain a little extra from timing?

        Also, can't wait to see one of these in the 9's. Mid 10's was with 670whp, with 130whp more 9's is possible

        most of the tracks up there dont open from winter until mid-march/ april so probably wont see any track results until then
