Progressive Dyno Results
This is the Dyno result from my first set of mod's (a base line, if you will) with the Renntech CF airbox, Green Filters, Evosport UDP's, AMS crank pulley (thanks Omey at AMS), Phenolic spacers, Denso Iridium IK16's, and the Sprintbooster:
Below is the Dyno result with all of the above mod's and a set of custom Evosport Headers (thanks Aaron at Stealth Auto):
I have just installed an EvoTech tweaked ECU (thanks Erick at LET Motorsports) and will post the Dyno results as soon as the car adapts and I can get to the same Dyno Jet (should be next week)
Any interpretation or insight as to the meaning of these dyno graphs would be appreciated, I am not paticularly skilled at interpreting their results and have based all my mods on the collective wisdom of this site.
All dyno runs were done on the same dynojet, at the same place, by the same guy on different days.
Regards,

Adam,
The Evotech tune is fantastic so far. However, it is very hard to get a good feel for its total effect as of yet, as the snow, ice and cold have hit NY -- my car is semi-retired at the moment.

Seems to be running strong! Had some nice tweaks for the baseline runs, but the headers definitely appear to have helped. If I read them correctly, the two test sessions were conducted under slightly different atmospheric conditions, and with a different correction factor.
Nevermind all that. How does it feel with all your mods at WOT? Nice work…keep after it.

I think alot of people think just pullies should get you alot more well this helps prove they don't without a proper tune and it might not get the half the websites claim....how long does it take for car to learn ECU tune? Nice gains with the headers
now take it to the track with your stock tires and drag tires

Marc,
glad you are still liking the tune! i will be interested to see what your next dyno shows
please let me know i can be of help in anyway...and i have not forgotten about the parts that i am supposed to check on for you, i will let you know something tomorrow on those...
thanks,
erick

Hello Marc,
Excellent. Glad that pulley worked out for you. those are some great numbers
. If you do the math assuming the proper 20% loss for autos... thats 397HP & 415 torque. Why go FI when you can get those kind of numbers from an NA engine .

Well yes you can get those numbers from a non aspirated engine but at a cost...easier to mod kompressor engines imo.

For the marginal cost a SC would be the way to go. Think about how much he's dumped into it so far. Headers what 2k? Airbox 1k+ ECU 1k+ pulleys 1k+ Other stuff and install costs prob2k. SC = 11k and how much hp diff??? HUGE. Not beating on anyone but it's always funny how the mod bug can be a fun factor.

I originally thought it was a C32 not a C55 and if it were me I would probably just save the money and get a SC instead....but at the cost of the SC its better to do his mods if money is at stake here...I seen a SC for C55s as low as 7k but its like close to 400 at the wheels. The approximates you listed for his mods can be had for much less especially if used.....1k for airboxes thats crazy imo...headers from LET were 1k in group buy tune also....I seen sites sell full airboxes for like $300-$500, used pullies even new can be bought for far less then 1k also if you search and are not in a rush.
I'm pretty sure that the listed prices are fairly accurate for the 8 cyl. AMGs. I believe Renntech Stage II (ECU, CF airbox, SS headers) for the C55 is around $8k just for parts.
Agree that if you're looking to "mod on the cheap" used parts is the way to go, if you can find them in good condition. For most people, that's tough, and can be a long wait.
FWIW, if I had a C55, I'd pursue the N/A tuning (i.e. ECU, intake, headers, etc.) and just leave it at that. A S/C'd C55 is a heck of a car, but you're really changing the overall character of the vehicle, IMHO.

Yeah but comparing C32 mod prices to C55 mod prices is a little apples and oranges, don't you think?

I know that the mods for a C32 is cheaper but I stumble into parts via websites just doing a search elsewhere on the internet and find cheaper listing for V8 parts just don't post them cause it has nothing to do with my car but next time I will post them if I am able to....

As promised and posted in other threads here are my progressive dyo runs done after the installation of different mods first pullies, then headers and finally ECU tuning.
The dyno graphs show on one sheet the best runs done on different days aftef the installation of different mods.
The first run was done after installation of the evosport udp's, the renntech cf airbox, and the AMS billet crank pulley.
The second run was done after installation of the evosport headers.
The third run was done after the evotech ecu tune.
Modest hp and tq gains were realized and the car is much more fun to drive. The first graph is corrected for standard SAE atmospheric conditions and the second graph showes the same information as the car actually ran on the day in question without the SAE corrections.

Oh well! Still nice #'s though.
Any pics of you A/F ratio as well,would be intereting to see.
Just log your timing as well because Evotech is known for doing alot of timing advance in their ECU's.(Ask the W211 E55 guys) Seems like they like pwr at the risk of reliability.
I gotta get my car redynoed and then give it a SW upgrade. (mods now are:Kleemann headers,dp,custom catback,custom intake setup)

Tump43,
Thanks again for taking the time to post this information. It's nice having an independent, objective viewpoint of various mods backed up via actual before and after dynos instead of going by what manufacturers "claim". Also the fact that they are sae corrected are even better. So far, based on the information you and others have posted, I would feel comfortable in purchasing some headers and knowing that it will in fact make a bit of a difference in performance. Also, it seems like the AMS crank pulley is a decent mod. As for the others - I would probably do the Evosport UDPs if it weren't for problems like flickering Xenons etc. Renntech CF AirBox..ummm, verdicts still out on this especially at that price. It looks like crank pulley and headers it is. Time to start looking..........

It's great to see someone showing valid data as a result of making performance mods. Very useful information! Thanks for sharing it!
What I've come to learn from this thread and a few other "mod" postings, is that you have to spend a ton of cash for very minimal results on an AMG car. The ol' boys in Germany seem to have maxed 'em out, leaving very little on the table for (affordable) improvements aside from the addition of nitrous. Of course you can also make a big gain with a supercharger, but that too is ridiculously priced.
I'm currently making 306rwhp via just adding K&N panel filters for an $80 investment. It appears by spending an excess of $5k there's only approximate gains of 17 - 20-ish rwhp, which is very disappointing in the "bang for the buck" category.
It really surprises me how little there is to be had in the tuning. On my previous LS1 car, I could pay $500 for a dyno tune/re-program, and pick up 20+ rwhp, because GM holds back so much in their factory programming. By what I've seen on the MB boards, is that it costs $1000+ for an ECU re-program, and you're lucky to get 8-10 rwhp gains. I hope yours shows more gains via the tune once it's ironed out. Please let us see those numbers when available.
Don't get me wrong, these are nice improvements, but at the end of the day this is why I purchased the C55 to drive daily while enjoying the nice factory performance levels, and I choose to race something much more economically "mod friendly"...
I'd still like to see your 1/4 times once the weather allows for it in NY. I'm glad to see you're not out running it around in the snow/salt after obviously spending so much to make it so nice.

Wawy: Agreed on the CF airbox mod. I got mine 2nd hand at a greatly reduced price. On my C43 I just dremmeled out the stays and extra plastic cast into the OE airbox. Doing so had the same effect as installing a renntech box. The flickering xenons are not a problem with the Optima battery. The evosport udp are really good, just need to upgrade your battery. Good luck with your mods!!!
JToups: you are dead right on the bang for the buck analysis. You don't get too much for the money. But, these boards let you take advantage of various deals when they come up. This is why I did my mods over time -- to enjoy each one and to keep renewing my interest in the C55.

My trip down to ICS was spur of the moment. I would still love to head down there again with you guys. The a/f sensors were not working last time I was there.
No trouble with the evotech tune as of yet. What do I really need to look out for?

-Correct me if I'm wrong but the Optima battery is for both weight savings and just a better performing one than the stock one right?
Also, "Optima RedTop 35" is there a specific model version in addition to this for our vehicles or that all one needs to ask for?
