So I ordered everything from the Stage-1 Power Package that Eurocharged offers:
-SC Pulley
-Heater Exchanger
-Johnson IC Pump
-ECU Tune

I also have done:
-Removed 2nd Cats
-X-pipe
-and Green filters
.....very basic setup daily driver setup


I dynoed my car today with the same Dyno that Eurocharged used and I got much lower results. The salesman claimed it was the calibration my Dyno tech got very offended and they had a whole argument over the phone. I specifically used that dyno because I wanted to basically copy that same power setup and have no other variables.

I like my Dyno guy and Jerry from Eurocharged seems very cool and informed but I can’t figure out why my gains are so much lower than their claimed gains
We had fans and my ITAs went from 90s to 140s then back down again which to my knowledge is somewhat normal, and I think timing does retard past 120 degrees but can that be the problem?

It’s also running a little rich towards the end
Any criticism, ideas, are welcome

It was a 4th gear pull....Im goign to do a 3rd gear pull once I get the split cooling done

You have to remember that every engine is hand built and it won't always put out the same power. Did you get a baseline dyno to see the difference? Also the dyno sheet eurocharged may have posted could be with a dyno tune which I hear gets you a bit more power out of it.

Because EC just copied and pasted the dyno graph from the 172mm crank pulley and put it in their 84mm SC pulley advertisement. The SC pulley boost is barely more than stock. No where near a 172mm as they claim.

Check this boost chart: https://mbworld.org/forums/w211-amg/...st-matrix.html

Eurocharged's advertising is incorrect and misleading.

You are incorrect sir. Our original 172mm pulley was measured from lip-to-lip instead of rib-to-rib and was actually a 168mm. The boost from the SC pulley and the 168mm are identical as measured on our Dyno Dynamics.

Regardless, the 172mm is no longer available and I'll have it removed from the website.

Thank you for the purchase and I'm glad you had a chance to take the car to the dyno.

Please remember that the car was already tuned before you installed and applied the tune for the pulley. The graph shows the gains from the pulley.

Tons of Dyno's will read different, even from the same brand.

Eurocharged now owns 3 dyno's and they all read different. 2 of them are the same dyno dynamics you used.

Don't get caught up in the Dyno numbers.

I'll also help you by doing a custom dyno tune if you want.

Thanks!

Playing number games can make things so difficult for customers to understand whats really happening. So many correction factors can be used for every kind of dyno. Eurocharged is even offering a custom tune. What else can you ask for out of a tuning company?

we never have issues with my dynojet vs track numbers. bottom line folks park your car if your going to start making dyno pulls from 90degs act and up.

Regarding boost increase with the blower pulley-

I have the blower pulley and the EC dyno tune as far as power gains. Car is PLENTY more fast with just these two mods and drives much smoother.

I used my PLX Device and the TORQUE V2 app and it showed a peak gain of ~2.5-3lbs of boost from stock. I peak at 13lbs now (generally speaking, stock boost is anywhere from 9-10 depends on elevation and other factors).

FWIW- I also have secondaries deleted, resonator deleted. I made the numbers in my sig with the listed cooling mods.

SPatykAMG

If I remember correctly the car begins pulling timing at 99° IAT which is why cooling is so Important.

Hulk

^^^ no that is way too early, starts at around 120* then gets more aggressive at pulling timing as the iats get higher.

AMG E Power

first off dyno in 3rd gear, 4th is to long. second you made a mistake by adding more boost to your stock cooling. headers and tune is always the best first mod on these car IMO and im sure ppl thats been around this platform will agree. I cant stress the cooling enough. enjoy your car

miamiE55

Thank You guys and Eurocharge for helping out so far

SilverStrk

This/\/\/\/\/\.. Take the custom dyno tune, do a 3rd gear pull Instead of 4th.. If you can add some headers, split the cooling and you should be good to go.. Long tubes Really help with cooling.. And yes timing is pulled at 120. Good luck..

Why are people so obsessive about dyno numbers? Who freaking cares there just numbers!! I know some members on here who make close to 550+whp and still run terrible at the track. Bottom line it's not about the peak number, it's how your car runs!! get some sticky tires n run the **** out of it then come back and tell us how Ya did.

ditch the Johnson pump and put in a fresh factory Bosch 010 pump (Johnson pump is worse than stock!). How vendors continue to promote Johnson pumps as an upgrade is beyond me.

Eurocharged website still shows same dyno image for 180mm crank pulley, and the 84mm supercharger pulley:

That is great support!

Well to be honest most of the people that do the sc pulley and tune are around 440-450. With headers many are in the 480 range. You already had a tune. From the 1000's of hours of research I have done on these cars my guess would have been 20 hp increase with the clutched pulley. Most get 40 rwhp form pulley and tune. there have been threads on this board about the tune seems to be worth 25 of that at least. The stage one Dyno graph on their site isfor a 180mm crank pulley. Either way your numbers seemed to have started lower than most I have seen. Depending on your goals you may want to ask them to go with the crank pulley. I'm sure you can work something out. What sucks is all 3 of the different pulleys have downfalls to them. There is risk with any of them.

Eurocharged is a good company. I plan on using them.

SPatykAMG

This is where I got the 99 from except it says 95.

Hulk

That's on stock cars and even then it's not that, by logging you can see where it pulls timing.

Tuner can advance that a little.

SPatykAMG

Good to know even though I have my Temps more than under control. Now if zeitronix would ever get the new Ndash in stock I would be able to log.

SICAMG

Speaking of IAT's.... a quick blast on the highway today and temps never got past 48 degrees F. Ummmm...but it is 28F today LOL. Gota love it!!!!!

menace2sobriety

And THAT is half the reason why I will be getting my tuning through them, good stuff

miamiE55

Do you find the torque App accurate? I use it also, I know the horsepower and torque readings are not but is boost accurate?
