    • Race video : Stock F10 M5 struggles with and gets beat by a stock P31 W204 C63 AMG in a 1/2 mile race

      More and more videos coming from the No Fly Zone event and this one is particularly telling. The F10 M5 has a twin turbocharged V8 and a dual clutch transmission. The C63 AMG in comparison has a 6.2 liter naturally aspirated V8 with an automatic transmission. Considering the F10 M5 has a large horsepower advantage of almost 100 wheel horsepower due to being underrated and putting down in 5XX wheel horsepower range stock a stock C63 AMG should be easy work for it especially in a half mile race.


      The C63 AMG has the P31 package which provides the 6.2 liter M156 V8 with stronger forged internals and a more aggressive tune. It is about equal to a C63 AMG with a tune on it so power should be somewhere in the low 420 WHP range. So the M5 has more power, but also a few hundred more pounds to carry.

      The C63 belongs to BenzBoost member @xtyper and he claims it is stock. The M5 is also stock. Hard to understand why the M5 does not pull away up top with all that horsepower.

        It is the P31 option package, available for all C63's.

        If this was the same guy named Sam in the F10 M5 then he couldve definitely been heat soaked IMO....I also ran him twice in my FBO 335i...First time I barely edged him out and then he got me the second time due to few issues I had...The owner was running almost non stop the whole day and from what I saw had over 25+ runs easily (if not more).....just saying the M5 definately had to be somewhat heat soaked a good part of the day since he didnt take many breaks...not to take anything away from @xtyper as his car is still a bad ass benz and won regardles Click here to enlarge

        The C63 Black Series makes more power from what I have seen: http://www.benzboost.com/content.php...yno-comparison

        Do you have a P31 baseline?

        From personal experience, heat soak is a $#@! and stock FMIC don't handle it well at all.

        But clearly the C63 won, good race!

        Let's just be happy the M5 didn't go limp. The owner probably did though.

        Planning to get a baseline dyno soon at my usual local Dynojet at SpecialtyZ in Chatsworth. Then I will install the longtubes and tune and go back.

        I was the Alpine White E92 335i with stock black rims...License plate 3DERTY5...

        Easy way to remember me is I had the $#@!ty stock rims on for the event...Only bc I was worried about popping a tire on the way to/from the event and getting stuck...

        Considering how this M5 performed against a certain Weistec C63 BS I figured this would be an easy win. Oh wait....

        It's not just weight it's aero.

        Despite having 100whp on an E60 M5, the top speed isn't any different. An F10 cuts a big hole in the air

        I know right ? LMFAO. How bout this - buy a car that isn't a piece of $#@! that can only run once before it overheats. I've said it before regarding certain cars and power adders that only have a short peak performance life - if they can't achieve the same, consistent results all day long on the street and on the track in 100 degree heat then it's a worthless piece of $#@!.

        EDIT -

        I ran the Weistec E63 biturbo and that thing never had heat soak AND it had the upgraded turbos. Go figure.
