Weistec Power: Stage 2 C63 dyno results
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:

We did not have an RPM pick-up. It wasn't working. That is why the X-axis in the dynosheets are set against speed and not RPM. We could only measure whp and AFR.
But from what I had previously seen with this upgrade ,the wheel torque produces between 530-550 lb/ft rwtq

ill look at this tonight

MBWorld Fanatic!
torque looks some what like this, only mine's from a mustang awd dyno which read lower. Stage 2 Weistec also. I've been trying to tell everyone the crazy torque these blower add, i think most just look at peak numbers. Instant torque, traction is rough at best.
2500rpm 470
2950rpm 500
3400rpm 510
3850rpm 520
4300rpm 534 - peak
4750rpm 520
peak whp was 538.

here's torque from the OP's SC run
RPM Torque % Increase (from base)
2441 527 36%
2929 538 28%
3417 546 27%
3905 565 27%
4393 568 27%
4881 549 21%
5369 528 24%
5858 493 25%
this corresponds closely to the above:
above peak HP ~540
OP's ~ 570
6% increase would increase torque ~ the same 6%
above peak of 534 x 1.06 ~ 566 for the OP, very close
what tire size? I used 25" OD
and this gearing
Final drive 2.65
4th Gear 1.37
RPM Torque % Increase (from base)
2441 527 36%
2929 538 28%
3417 546 27%

^^ Dont worry about dyno numbers man
There crap i went from one dyno at 335rwkw to another 295rwkw
as long as it smokes the tyres and pulls like a steam train your right to go

The conditions of the run don't matter. This isn't the track where DA is very important.
What the car runs on a dyno, is what it will run anywhere in the world on the same brand dyno.
That is what the SAE correction does, converts the power to sea level.

Except that for higher temperatures, like the above dyno run, the Knock sensors are effected, thus reducing engine performance and reducing whp. Therefore when you run the same car on the dyno in a cooler weather, particularly 60-50F, it will produce more whp figures, maybe 15-20hp more from what I had seen
I drove the car last weekend and raced a couple tuned CTS-V, ZL1, the new Corvette C7, and some GTR's. The car is just a pure animal and was beating everyone

Should trailer the car or let it sit over night before dyno. These cars run hot and get bad heat soak.
I am hoping to get on the dyno soon. I just got a smaller pulley to try out.

^^^^ cant wait to hear those results
#21
Stage 3 with a smaller pulley
This will be epic.

Heat soak is a f*cker with these!
I've noticed that with mine, there was a significant change in power on the dyno.
One figure was high (the day the car wasn't used much)
The other figure was much lower (car was being tuned all day, software tweaks, dyno runs/pulls)
The heat soak is incredibly noticeable!
Ice Tank is def the way to go aswell..

The smaller pulley is a 60mm I believe, there is a 68mm on it now pushing 10psi.
The 60mm should hit 13psi.
I don't have a built engine, non-p31.
I'm only going to run it at the track, with race gas 105oct and with ice in the tank.
Going to test on the dyno to see if the car will adapt to it first though.
With the 60mm the stock belt will work I'm told, anything smaller needs a belt change.
I am bit nervous, we will see how it goes...
