Hello all,
I am new to this board. I just purchased a 2005 e55amg, shipped it to Corey w/Kleemann and did a stage 3 upgrade. I did not know about the break in period you're supposed to do. I shipped it with only 200 miles on it and Corey just informed me that the baseline dino read only 444 hp and the stage 3 read 547 hp. He said the hp will go up between 600-610hp with about 2000 miles on it. For all you experienced users, Did I make a mistake in doing mods that early? I spoke to my mb dealership about the break in period and he said not to worry. It is only for earlier models. The 2005 is refined and as long as you stay out of the red zone you should be fine. Should I see 600hp in the future? Any comments would be greatly appreciated.
Thanks,
Gianster

Congrats and welcome. Your car will be fine. Break it in the way you're going to drive it. These motors are run at the factory and all of the critical parts are broken in before we see the car. Keep us posted on how you like the Kleeman kit. I am in the market for more hp and just haven't made up my mind which company I'm going with. A lot of guys here like the Kleeman product so I'm sure you will too.

gianster - You should have no problems with your break-in period on your new E55. You will hear many theories on break-in methods here and on any other automotive oriented board. I have been a motor head for over 45 years now and have built, raced, and hot rodded four and two stroke motors ever since I can remember. My experience and research over the years has led me to believe that a motor that is run aggressively from the very start will seal up tighter (piston ring to cylinder wall seal) than a motor that was driven easily during the break-in period. The reason for this, from an engineering point of view, is the fact that the rings are designed to be pressed up against the cylinder walls by the exhaust gas pressure produced by the combustion process and, added to this, the cylinder wall honing texture is most abrasive when fresh.

Now, with larger throttle position angles (aggressive driving) the effective compression ratio is higher therefore the piston rings are being forced against the cylinder walls harder when the cylinder wall hone is most aggressive (new motor). So, the lapping of the rings into a tight harmonious seal with the cylinder wall is more effective during the first 1000 miles a motor is run. Now this does not mean you can just go out and flat foot it for a five minute ***** to the walls run, what it does mean is you can run the motor hard for bursts of 20 to 30 sec. at a time and then let it cool down and then do it again. After all, the motor is in a relatively high state of friction and does produce more heat than it will after it is broken-in.

Also, the other thing that happens when breaking in a motor is the production of metal oxide from the lapping-in process of the rings, and this metal oxide is carried thru the motor by the oil, although, suspended in the oil, I personally feel a couple of oil changes during this break-in period and a third one at the end of the break-in period will keep this suspended metal oxide at a lower level and reduce the possibility of adverse wear on any of the bearing surfaces. I know, synthetic motor oils don't suspend the metal oxides as well as "Dina sore" oil, but the oxide still has to settle out to the bottom on the oil pan and that takes time and during that time they are suspended in the oil and being pumped thru the motor.

So, having said all this enjoy your new E55 and exercise it hard in sort bursts, cool it down and go for it again, and you will have a stronger running motor because of the better seal at the piston ring to cylinder wall interface. Good Luck! - Bob

This sounds like the same method as Marcus Frost's friend, Lance Wolrab. One question though is how long do you "cool it down" for? Does one pull over and wait an hour? Or slow down to let's say 60 mph or so and then burst it again for another 30 seconds or so?

Please explain the cool down method.

Is this flywheel horsepower or rear wheel horsepower?

DFW01E55

I was told by an AMG employee that the engines are not run or broken in at the factory.

They have a pressure test that's been validated to show any low performing engines and those are pulled and fixed. No running time at all.

Can Drive 55

Kleeman measures rear wheel horsepower and they then use a formula that takes into account drivetrain loss and convert it to flywheel HP. It is not an exact measurement, but fairly close.

WELCOME dude, the more the merrier, btw, what did you come out of???

vdubpower

Yeah, like you will be able to tell between 550hp and 600

Marcus Frost

Uh, you should definitely be able to feel a 50hp difference at that level, it's nearly a 10% increase in power. I've had cars in that power range and 50hp is a noticeable difference.

AMG BLISS - Just normal driving will do for a 5 min. period and then your ready for another blast. - Bob

I don't care what you've been told, that's completely wrong. They are not sending out a motor without it being fired up. I guess he's telling you they have absolutely no quality control at all??? If you've been around motors or cars at all you would know that's a ridiculous statement. Find out what he does for AMG, I bet it has nothing to do with building motors.

gianster

Thanks for all the input. Would anyone care to share dyno results after k3 mods?

Gi,

Welcome to the club.

I'm with Marcus on this one, having also had a MKIV Supra. A 50rwhp difference can be dialed in just by turning up the boost. There is a very erceptible difference, even at those power levels.
I am actually a bit disappointed that the car in question is only putting down 444hp from the factory, even before breaking it in.

gianster

Thats what i say. I can't believe my car, even with only 200 miles, would only put up 444 horses. I believe everyone saying that the car would improve with mileage but getting stage 3 kleekann from 547 range to 600-610hp range seems unrealistic. I would believe it more if it were a coulpe of horse power but over 50+. I don't know. Any thoughts would be greatly appreciated.

DJE55

440 hp at the rear tire is a lot. If the motor is rated at 469hp at the crank he's got more power than it's advertised.

Gid_E_Up

Everything is fine.

ProjectC55

I agree.444hp at the wheels comes out to over 500 hp at the crank.

gianster

Sorry if I come direct. But I would like to know if anyone here has had k3 mods done and would like to share dino results. People like to post but no results. Does anyone here have what they say they have?

vraa

The motor is the same as the one in the SL55. It's still 493 at the crank or so. Makes it much more believeable then the 469 that AMG put on paper.

gianster

Still looking for anyone with k3 mods.

medici78

I think you guys missed the post where the owner stated that it put out 444hp AT THE CRANK.

gianster

Thanks med. I have 444 hp at the crank. Has any one here done the k3 mods ? If so could you please share dyno results. I don't want to seem rude but i have read every theory known to man. Everyone wants to post thoughts but i have not heard from someone that actually had the mods done. I keep asking and asking. People respond but not people that actually had had the mods done. IS THERE ANYONE HERE THAT HAD K3 DONE AND WOULD LIKE TO SHARE DYNO RESULTS!!!!!!!!!!!!!!!!!!!!!!

medici78

Did they tell you the rear wheel horsepower? For all we know, maybe their conversion is somewhat conservative. 444hp at the crank would put you below 400rwhp which is extremely disappointing for a car like the E55. Pretty much all my experience involves RWHP, which IMO is the true measure of a car's potential as it is what is really being put to the ground. People would freak out when I told them it made 667rwhp. Most people are used to the flywheel horsepower numbers manufacturers state, so for comparison I corrected saying it was (conservatively) 750hp at the crank. I really hope everything turns out well for your car. Dyno it after you break it in and post results!
