lol, ya'll think these heatsoak so bad. You have no idea what a kompressor 55 motor and v12 feels like, they have BAD heatsoak. Atleast the weistecs are really only noticeable on the dyno. driving around it's I cant say i've ever noticed. On the dyno mine really only dropped 10-20whp over the course of a few pulls. That's in texas heat too. The 55's and v12's will go into a limp type mode w/o throwing a cel and pull boost and timing. Output of 9:1 without boost and timing is no where near 11.3:1 without timing.

3 sec dynoruns?
Hello;
Good power update. Prize about kit?
But have anybody dynotested these with real rolling road dyno, with 20 sec dynoruns like Maha ? https://www.maha.de/en/products/perf...w-allrad~p2018
These 3 sec dynoruns do not tell anything about real road power.
Intake air heat will reduse power very much with longer dynoruns.

I recently modified a 2012 C63 AMG for my friend. it previously dynoed 450rwhp with an ECU tune + Supersprint headers.
Here is the previous dynosheet:
I added a 2.3L to it and the car just runs amazing. It beat a couple of modified 2013 Shelby Mustangs, some modified GTR's and a couple of ZL1's. I took it to the dyno. It was crazy hot. Temps were around 110F. I was really surprised to how well and consistent the beast dynoed in this hot weather. All 5 runs were close (within 10 whp difference from min to max).
The car does not have an Ice Tank, it did 572 whp, a gain of 122 whp from the previous dyno run on a hotter weather. I want to thank Weistec for calibrating this car with an amazing software tune as promised.
Here are the post dyno results after the supercharger upgrade:
Here is a short video of a dyno pull

Here are the conditions of all the runs, very undesirable conditions, but the engine was surprisingly consistent:
Here is a comparison graph between the previous runs and runs after the supercharger upgrade, a healthy whp gain:
