Is it the car? Is it the atmospheric conditions? Is it the dyno? Is it the dyno operator? Or perhaps a combination of all?
Would you be satisfied with these results?
When I had my 430 dyno'd there were a couple of NA 55's there that day. Your numbers seemed pretty close to what I remembered them putting down. I dug up my old thread and found this.

The conditions were probably slightly better up here. I seem to remember it being around 60 degrees that day.

My car's traction control was fighting the dyno hard until I unplugged the module. Violently bucking and the power was way down. Neither of the 55's had that problem.

Cudaized,

Can you take a picture of the cable as to which to unhook the ESP when you take your car back to the dyno shop. Would appreciate as the pics on the link is kind of unclear. I bet some of us, including myself would like to dyno our cars in the near future and to make sure we had this wire unhook before doing it.

Dyno prep - disconnect the ESP for E55

Already done Sir.
Here are some pictures.

Your numbers are WHEEL HP numbers. That's are actually very good numbers. 296/.82=360 HP. (That's for 18% loss which is about avg for a dynojet)

Technically on the w210 E55 AMGs, there is no Dyno mode, you have to disconnect the ESP module via the big rectangular plug behind driver side headlight.

I was expecting about 15% loss for the hp. The 16.4% hp loss is acceptable, but I think a little off.
I was disappointed on the torque numbers. I think that the ESP did hinder an accurate dyno pull. 21.5% is too much loss.

I will try again with the ESP unplugged. Looks like I will have to wait until tomorrow or Wednesday for the next dyno session. I should have thought about it yesterday.

Net differences: ESP not unplugged, but de-selected inside
296.85/355 = 16.4% hp loss
306.28/390 = 21.5% ft. lb loss



I am hoping for WHP dyno numbers: 305 hp and 330 ft lb. torque That is my guess. Lets see how accurate I am.

I picked up my headers from the machine shop. They are true (flat) now. Minimal flange surfacing on a large table belt sander. $20 for the pair.
* incase you want to know: only the flange that attaches to the cylinder heads was sanded. Not the down pipe.

That's really a good deal...I paid $50 to sand both flanges
Everything in the northeast are expensive.

I'm paying about what you guys paid combined. Everything in the Bay Area is more expensive.

I'm also too lazy to shop around and these guys do awesome work. They're a 30 second drive from my work too.

Thank you very much on the picture procedure. Now we have picture documentation of the ESP plug. You dah man

I guess if you were to drag your car, you should unplug the ESP right, or would it harm the engine???

New - Dyno run - base test (ESP unplugged)

08-31-2013 (Second attempt at a base run)
I did a new base dyno pull today. It was 5 degrees hotter then two days ago.

I first tested my car as I had it set up two days ago. ESP still plugged in under the hood, but ESP de-selected inside the car. No other changes. The third picture shows almost identical runs from two days ago.
08-29: 296.85 hp / 306.28 ft lb.
08-31: 297.18 hp / 307.42 ft lb.

The next test I unplugged the ESP under the hood. We did two runs one in 3rd and then in 4th.
300.29 hp / 309.38 ft lb. torque

I gained 3.44 hp and 3.1 ft lb. and remember, it was 5 degrees hotter. Just by unplugging the ESP.

Net differences: ESP unplugged
300.29/355 = 15.4% hp loss
309.38/390 = 20.7% ft. lb loss

I will use these new numbers as my base dyno run.

Now on to the header installation...

I installed my headers today.
It was a straight forward job. I thought it was easy. I took my time and did the entire project in about 4 hours.

Here is the measurement of the exhaust port of the cylinder head and the collector-down pipe measurement. The collector is a smaller diameter pipe then the primary cat. The exhaust pipe then appears to be a consistent diameter all the way to the rear muffler.

***Note*** The down pipe on the driver's side, just before the primary cat, is crushed by the factory to clear the steering coupler.

I will drive my car for about 100 miles. I think the ECU will adapt by then. I will then do another dyno test to see what changes that the headers will give.
I have not done any other modifications. Just installed the headers. I am looking for an honest comparison.

Awesome pictures and great comparison on the measurements. When you do the dyno run try to pick a day when the temps are lower then 90 degrees 😊the heat can push the actual reading down too.

I did not notice any change in exhaust sound at idle. There was no "header tick" that I have in some of my other cars. If I didn't do the installation myself, I would not think that anything was changed from stock.

Driving it, is somewhat different . As I "test" drove my car, I noticed a better exhaust sound. Deeper, more authoritative at mid range and higher RPM.

I am on my way to do the next step: remove the secondary cats, remove the resonator, add an x-pipe, and am actually contemplating replacing my primary cats with some high flow ones. (Also wondering if I should address that crimped driver's side down pipe prior to the primary cat. It bothers me)

Seriously, AMG change their way of thinking after this model as the W211 is like night and day with the exhaust note.
Drive it for a while and you will notice more and more prominent on the exhaust sound as you step on the gas pedal, every time

Got the "mod" bug? Once you start....you have to keep going
