499.82 WHP Dyno - Flame Suit On

Thanks to the men at EuroCharged Canada for their great work.

Mods on car on first dyno pull:

Charcoal delete
KN filters
FI Headers (SS coated - more on this later)
200 cell cats
2.5" welded H Pipe
91 octane EC V7 beta with raised TRQ limit

First two were baseline runs 479 and 485. After tuning, car approached 500 consistently with as close as 499.82.

The guys told me that this is the second highest power made with these mods! Only one previous car cracked 500 (he who shall not be named).




For me, ceramic coating the headers was probably my smartest decision since buying the car. Thanks to everyone here and BLKROKT ("Don't half *** this like you want to do with everything else" too true). My engine oil temp is much cooler. I was ran 105c, which seems to be my car's desired oil temp, in situations where I know I would be 115c previously (manual shifting at 3-4k in dirty traffic air).

The dyno run was ear splitting loud. The (concrete?) floor and the entire shop was shaking from the sound. On the streets, car really opens up at 2.5 - 3k and my rear end is a lot more loose. Even medium throttle in third gear I've had a little tail play. I'm loving this.

do you have the run file so others can overlay onto theirs and look at correction factors? if you don't then it doesn't matter, and its a dynojet. do the same on a mustang or superflow ANYWHERE then i'll care.

thanks for sharing though. nice gains!

Thanks! I asked them for the file for analysis and they said yes they can provide it. Will get it tmr.

These 200 cell cats aren't doing crap. Car is really smelly. Will it take time to break in cats or is this how it is?

Maybe theyre not being heated enough? Headers are ceramic coated and cats are at where secondary cats were.

I'm really happy with the dyno numbers and more importantly, the increased power/sound but I'll be honest, the fumes are making this much less enjoyable and more embarrassing for me.

It's not uncommon for new cats to smell for a while. Give it a little time but drive around and get them hot. Good to hear everything is going well with the motor!

Were you the matte black coupe? If so, cold start in the shop sounded like a shot gun! Sick car and some great looking numbers! Too bad you weren't there while I was getting my tune/cat delete.

Yes sir that was me! Thank you for the kind words. The paint is magnificent on a bright day right! When were you there?

I showed up around 10 while your car was on the hoist. Left around 12:30. Would have been great to chat! Next time

I wish my ceramic shop did screw my timing and force me to skip doing it.im glad it's working out for you.
​​​​​​
When I get back home I'm also installing 300 cell cats.

If you think it's bad with your car now just imagine what it's like with no cats lol

it's not that bad. I have no cats totally fine. you smell it occasionally if wind is right but hardly. I'm running e85 though will be interesting once I go to 93. A lot of stuff on here is eggagerated in my opinion like header sound exhaust smell.

E85 burns so much cleaner than regular gas though.but I agree on the sound as it's not nearly as bad as I expected from the forum posts

Baller, any chance you can email me a full throttle log in third gear to redline?

Nice numbers bro!

What is this raised TRQ limit you speak of? I'm assuming this is a custom tune they did to your car? They loaded V7, ran a baseline and then played with a few of the parameters?


I wanna hear the beast in person.

Thanks skratch. The ceramic is good only because I felt I had high oil temps before. If oil temps/engine heat are not issues, then there is minimal value in getting ceramic coating. Hopefully there is just "break in period" for the cats (would like some input from more experienced members). No cats is insane, and it smells like my cats are not present either.


Ill ask them for the throttle log. Not sure if they did it in third gear though?

Thanks man.

On my baseline v7 beta tune, raised TRQ was something Jerry tried for me because I was complaining about a go - jerk - go when violently stabbing the throttle from inside power band in 2nd and 3rd gear. He told me there are two TRQ variables in our systems, and I think one is in the ECU and one in the TCU.

Ultimately, changing the TCU TRQ variable is desirable, but something something somehow changing the TRQ in ECU can allow it to request for more TCU TRQ? I'm a bit hazy on the tech specs. There is a GREAT thread about it here: https://mbworld.org/forums/c-class-w...tle-delay.html

In hindsight, perhaps this was just pure speculation on my part. I still got a tiny bit of this Jerk once yesterday even with the dyno tune. I think hitting the kickdown switch may have something to do with it?

NotABaller, who did the coating for you? Nice gains.

Be aware, EC Canada no longer does emission test so you are on your own when it is time for sticker renewal.

Wrong again. There is a lot of value in doing it, and the primary reason isn't even for keeping radiant heat down.

Improves exhaust flow and velocity. Reducing under hood temps is a byproduct of keeping the exhaust temp higher inside the headers.

Nope. It was in my head. I'm in Venice with crap service and not a lot of time to post things. But you can check with the Google machine. I think it's basically right.

Insulating the headers spools turbos faster.
However, the header section of the turbo cars exhaust already runs at yellow hot temperatures. So coating reduces the life of those headers, in that world, 40% of the aftermarket headers are worth buying and last beyond 1 year.
Also, because the turbine housing is bolted to the exhaust and oil is trimming through the center cartridge, for the turbo cars the oil temperature increases.
Also if you get an oil leave from the turbo, and you tape wrapped the headers, you can get an oil fire.
On the plus side, the spool gain can be 300-500 rpm, quite a lot.

You are correct technically. The ceramic coating is highly non conductive which means less exhaust heat gets lost to the pipes (they stay colder) therefore the exhaust gas stays hotter. And as you guys know, hotter stuff goes faster so a hotter exhaust gas will exit the car faster, leading to GAINZZ.

But my primary reason wasn't for hotter exhaust gas or better flow, it was to lower my engine temps. It's doing both so I'm not complaining!

On the other hand, I'm going to my local exhaust shop to put resonators back on to try and tame the sound a bit. Revved it downtown last night and it sounds like a war zone. The sound is so powerful.... I'm basically driving around a bomb with wheels (in sound department)

Can you post a video? I have one of mine and want to compare before I take my x out
