• Renntech sets new World's Fastest M157 record running 10.7@130 in their 2012 CLS63 AMG

      Renntech continues to keep raising the bar with the AMG M157 twin turbo V8. The first run in the 10's on this platform was a 10.9@129 earlier in January of this year. After that they were the first to break 130 miles per hour through the traps on the platform running 10.9@131 in March. This run sets a new quickest record at 10.79 although the trap speed record is still 131. In better conditions (this took place at PBIR in 85-90 degree weather 2000+ Density Altitude) we expect the trap record to fall fairly easily.

      Modifications to the CLS are Renntech software, larger heat exchanger, upgraded intercooler pump, limited slip diff, downpipes, high flow cats, and drag radials. The car does not have any weight reduction and is still on the stock turbos as well as airbox which are the next changes coming.

      Very impressive work as usual from Renntech.

        Do you know what is the diffrence between stage1+ and stage 2?

        Its not much!

        What jim and Earl were runnig when they had Stage2 is not much diffrent then what I have. Thier Stage 2 consists of othe fuel system upgrade.

        They can also confirm this. The diffrence between them and I is that they had the fuel system upgrade. This consists of larger fuel injectors.
        The reason they were making 660RWHP was that they both had the race ported heads and a custom race tune (which can be purchased with stage1)
        There is another C63 that ACG worked on (featured in SEMA), that dynoed 630 RWHP. This also had the race ported heads and te fuel system upgrade and tuned on CA 91 pump gas.





        Sticky, I ran an M157 CLS63 runing a tune and downpipes. It wasnt close!Click here to enlarge

        Sirex63 ran the E63 that raced the tuned BMW M5 (Video Posted) and was also ahead of it!

        Look a Stage I will be slower but I think the two should be a good race. Would like to see vids.

        I was there at that event and at mid day temps on the track got to 92 - 95 . I can imagine what that car will do in 60 with new turbo upgrades
