My car is at VRP right now...
Dropped it off this morning...
- Shorty headers
- Both primary and secondary CAT's being removed, with a cross pipe being installed
- VR530 (Underdrive pullies, HiFlow air filters, Phenolic Heat spacers and Intake temperature relocating harness)
- ECU Tune and speed limiter removal
The car will be dyno tested on Wednesday morning after everything is installed. I am told they are predicting 570 flywheel hp and 475 rwhp.
Will post dyno sheet once I drive back from SoCal to Scottsdale...

1. I would assume they do regular W204's. Confirm w/ Vadim at (949) 584-4446.
2. I was going to get a Quaife LSD, but Quaife USA nor its' sales reps can confirm if it will FOR SURE fit the C63. They don't want to open it up and spend all day to find out it can't be done, so this may have to happen on another trip.
3. I'll make a video of the exhaust at some point.
4. Don't know if I'll pass smog or not. My car is registered in Oregon and driven in Arizona primarily, so we'll find out 2 years from now... I'm keeping the CAT's just in case.
5. Lastly, as far as a baseline dyno (this is where people are going to not like my answer), I don't think we are doing one SPECIFICALLY on my car. VRP has done several, and I even think MHP agrees with the numbers. The C63's are producing about 374 rear wheel horsepower.

We know the cars with the same engine can make 505 to 518hp. So just an ECU tune to stock for an E/S class is going to produce a 50-60hp gain. Headers will probably add 25. Removing the CAT's may add 5 more. So that means the relocating the thermostat, better pullies, heat spacers, and better air filters only have to provide about 10 - seems reasonable to me.

Cant wait to see the results. Regardless of all the numbers, your car is still going to be one ridiculous beast after all that work gets done.
Congrats

I'm hopeful for you, but I'm very doubtful you will pick up 100 hp and it looks like will never know.

Gravedgr: I appreciate your comments. Multiple cars, both from VRP and others, have agreed that a stock baseline dyno for a C63 is +/- 1 or 2hp from 374 rwhp. If my car tests out at 474 rwhp, then it's a 100 rhwp gain. If it shows 80 or 90, then so be it. I think the gain (and consequential performance) will be worth the money I am paying.
I will summarize on Wednesday night or Thursday with dyno graph, pictures, video, and whatever else I can come up with.

Hans: Sorry, don't think so. You can call Vadim though at VRP and see what he could tell you.
Surf City, USA... Is that Huntington Beach? I was there tonight, farmer's market on Main street, out on the pier, etc. SoCal has been nice, but can't wait to get my car back and be back in Scottsdale.

Mods are all about +gain from baseline, not some particular peak number achieved from a single pull (let me clarify - we want gains, tuners/marketing want "best case" theoretical max results). Those kinds of results are very easy to fudge. I'm just very skeptical as I have seen a large number of "objective" dyno results used as proof to sell products which when tested scientifically by a third party produced ZERO results and often led to detrimental performance.
I'm only asking as I'm considering similar mods, and this kind of scientific (as good as you can get from a dyno) testing is what I require to spend the $$$. For you - so long as you're happy, that's all that matters. Good luck!!!
PS - I would almost best $50 they'll doing pulls on a Dynojet. If you happen to get a peak, look at the model.

If OverBudget goes to the same shop Vadim used when he dyno'd my car (and I bet he does) then he will be on the same dyno. My C63 dyno'd at 374 to the wheels on that dyno, and yes it was a Dynojet.
OB, yes I'm in HB. But I was born and raised in Arizona.
edit: BTW my dyno was on 91 octane.

You know what.... I can't remember exactly! But it was right after I did my first oil change so I'm going to guess it was around 1500 miles. One fan and I'm pretty sure my hood was open. All filters, completely stock.

Yes, it will be the dynojet. I'm running 91 octane also. I'll have the hood open, trunk open, doors open, tic tacs in my mouth, etc.
374, 373, 376 - it's all the same to me. Take whatever number I get for the final number and take it +/- 5rwhp if that makes anyone feel better...
Sorry for the sarcasm. My bottom line is that the cars are dyno'ing at ABOUT 374rwhp on a dynojet. Whatever I get minus 374 is the gain (in my mind).
