E63 dyno numbers
So I went to the dyno today to have a baseline before I tune and decat my E63 and I have mixed feelings on my results. I made 2 runs, I drive 2014 rwd e63 non s. As you can see the first run was my best, the car was cooler I assume and I made 520 rwhp, I was very satisfied but for little time, as I made the second pass I lost almost 100 peak whp, please look at the graph, any takes on what happened? The tuner told he thinks I may have an issue with my ic cooling system, what do you guys think?

It's hard to see, but I'm seeing this:
Black Solid Line: HP, Run 1
Black Dashed Line: Torque, Run 1
Green Solid Line: HP, Run 2
Green Dashed Line: Torque, Run 2
...and HP and torque on both runs look pretty consistent. Nice numbers!

Do you see a 100whp difference? at the highest rpms I see a drop off but the peak hp seems about the same for both runs

At exactly 5500 you can see a drop of 80whp maybe I exaggerated but it's still 80 whp and torque as well, the solid line belongs hp and dashed tq, black is fist run green second

if the engine is spinning at 5500 rpm, as graph shows, then they didnt let off the throttle
to op, i would say the original assumption of weak IC system is correct.... although you do have 2014 so it should have the updated/divorced IC system, so i would think then maybe you have a failing IC pump

im thinking same due to high IAT's pulling timing... its was 98F when he dyno'd .... probably needs to check ic pump

I thought all the MY14 E63 were 4MATIC, are you sure yours is RWD? If it is RWD maybe it is a MY13 ? I have a MY14 CLS63 (an S model, just has a more aggressive factory tune), it was only available with 4MATIC and has separate turbo and engine cooling loops. I thought the E & CLS were essentially identical in terms of drivetrain.
At some point around MY13-14 there was a design change that separated the turbo and main engine cooling circuits, if yours is RWD it may still have a shared loop which might explain the change. If so there are aftermarket solutions to separate the engine and turbo intercoolers.

either take it out and hook it up to power source and measure flow rate, or just replace it and see if it fixes it.. they are not super expensive and at some point all of ours will fail... just depends if at 25K , 50K, 100K , 500K miles etc...
