Tony from Eurocharged ran the dyno (Dynojet) at the Eurocharged Vegas Tune Day. No baseline was ever run before the mods.

Mods:

-Kleemann K1
-"ROW" AMG airbox tops
-K&N filters w/charcoals removed

Conditions:

-65 degrees
-17% humidity (approx)
-2000 ft elevation (approx)
-1673 current mileage at dyno time

Max results after 3 pulls in 4th gear (SAE smoothing 5):

421.75 HP/384.30 TQ




It was good to meet you, Tony.

Nice, but can't really say much without a baseline dyno.

^^^ +1111111. It is great to see the final numbers but inconclusive to see the real gains compared to stock. We appreciate you sharing with us though.

Thanks for sharing, Sincity. Nice clean curves!

How did your car compare to the other C63s that were running?

Sincity

Vegas_AMG was about 7 less on HP and TQ with this Eurocharged tune. He is still using stock box and filters but without charcoals. He also doesn't have a baseline to compare to. No other C63s showed up. There was a CL65 putting down 605HP to the wheels, but I forgot what his TQ was.

My tuned numbers are pretty close to what you have (K1, filters, charcoals removed). I also noted that temp was close to the same, but our humidity is much lower and elevation is much higher.

605 to the wheels what a beast.. Ok, so NOW we have your base line from here on out your clime begins.. Have some fun

superlubricity

Yep. Notice your SAE correction factor is much higher? (1.04 vs. 0.96) It adjusts your output based on the differences you mentioned above.

Next time you go to that dyno, bring a USB flash drive. You can download the runfiles (even today's) and view them at home in WinPEP software (free from dynojet.com). This will allow you to play with the data and even see the actual uncorrected horsepower/torque from each run.

So this would seem to indicate that the K1 and Eurocharged tune produce very similar HP results. You had 7HP more but you have K&N's and ROW. Interesting because I previously thought the K1 tune produced approx. 10HP more than Eurocharged. Great info - thanks for posting this.

Sincity

You should have heard that car. The owner had a custom turbo back exhaust and retained the stock AMG tips. Looks OEM from the outside.

My budget is nowhere as big as yours. I will be taking "baby" steps. Can't wait to see what power your new mods will net.

Sincity

This stuff is all new to me. Thanks for the advice, I'll head down there sometime to get a copy of the run.

Sincity

Probably pretty close and the price is right. He got 4 pulls (because he is already an EC customer) and his car had a longer warmup time; if that makes a difference. I only got 3. I don't count the first pull because the ebrake was on. The second pull was 415 and the third the 421 you see here. I should have asked for a fourth pull.

Just an add-on to this: if your dyno shop's computer has an internet connection (and really, they should these days), they should be able to email you the raw data from the dyno runs. You'll still obviously need WinPEP7, but then can analyze the data from the comfort of your own abode, and to your heart's content - and might save a trip, if you don't live close.

A full 4th gear dyno run was performed with the parking brake on?

Sincity

Yeah. I don't know how Tony missed that one. I don't think it was cooked because it didn't smoke but you could smell it.

superlubricity

No. It would indicate these two cars were similar in terms of their peak output on the dyno on this day. You can't make blanket assumptions without a baseline or a lot more data.

avengerboater

K&N filters gives you absolutely nothing in power gains. All it does, or can do, is mess up your MAFS. Airboxes can give you a bit more hp, but that likely won't show up on a dyno, unless that dyno can create 120mph+ winds.

peh-amg

Very true. It's interesting data and it's the first time I have seen/heard results of two different tunes done on the same dyno and the same day. Or are there other expamples of this? I've searched and couldn't find any direct comparisons.

peh-amg

Good point

What's your opinion when comparing EC to K1? Is one better than the other? It's an honest question because I don't know and can't find any unbiased direct comparisons.

superlubricity

I only have direct experience with the Kleemann K1 on my car.

Here is a post worth reading -> https://mbworld.org/forums/c63-amg-w...iscussion.html

wha is ROW" AMG airbox topst?
nice gains.

Sincity

"ROW" (Rest of World) box on right and NA (North America) on left:



Airbox: https://mbworld.org/forums/c63-amg-w...mystified.html

In your opinion, are the ROW's worth it? Can you "feel" a difference? This is a mod that I am considering too but trying to decide if the cost ($500) justifies the gains (approx. 10HP?) Also, are MAS easy to take out and put into the new ROW airboxes?

Appreciate your feedback.

Sincity

I cannot "feel" the difference per se. What I can tell you is that when I started the car up, the cold-start is just a little bit louder. A difference you can tell. The MAS/MAF is included with the new box tops.

Vegas_AMG

From what I recall the TQ was 738!!

peh-amg

MAS/MAF included - good to know, thanks. Where did you buy your ROW's from? Price?

Sincity

I got mine from Overbudget. You can get them for less than $600 for the pair.
