Normally the bigger issue is running to little timing which causes egt's to sky rocket big time and heat transferred to the heads and to the pistons can cause decent damage, even though it's at a somewhat slow pace when compared to detonation obviously.
A lot of heat can cause the piston rings to butt together and break a ring land, which to me is the single largest reason why these engine break as much as they do....more related to heat that detonation it's self.

I don't see more than 19 * timing towards redline (but my tune is for 91). The factory tune saw similar timing (I logged when the car was 100% stock). I would rather go conservative on timing ( a few degrees) and leave a few hp on the table and be safer. Also from my experience with FI cars, you will make more power with more boost and less timing than the other way around....

While high boost and low timing due tend to make more power than the other way around, the way the car puts the power to the ground is a lot smoother ( as can be seen on a dyno graph ) with high timing low boost. It makes the car pull smoother...but yes, it'll still be slower...lol.
And of course, as mentioned before, to low timing will cause high egt's which can kill your engine in the long run.

What happened to Dennis's car has nothing to do with the tune. Once all the facts are out in the open, it will be clear what the cause was.
I have chatted with the best in the industry about his car, some that know his car well, technically and mechanically. The events leading up to, and after the pull, will tell the story why the damage occured.
Hard facts will become apparent as the complete motor is examined.

About mid to low 30's at part throttle, and it can vary a LOT depending on load and get into the mid 20's with ease. You'll see high teens low 20's at wot.
Normally the bigger issue is running to little timing which causes egt's to sky rocket big time and heat transferred to the heads and to the pistons can cause decent damage, even though it's at a somewhat slow pace when compared to detonation obviously.
A lot of heat can cause the piston rings to butt together and break a ring land, which to me is the single largest reason why these engine break as much as they do....more related to heat that detonation it's self.

I am not monitoring EGT on my e55, so I cannot comment.

2005 E55 AMG....Speed is Relaxin'
Sorry to hear about E55 down.
I live in Austin and have MODs
On my E55 too. Patrick is my mechanic.
Great with diagnostics, repairs, and a
HONEST guy too. GOOD LUCK !!!

There is a bit more to it than this, but you generally run in two conditions : open and closed loop. Under 'Open loop' your ECU is trying to keep the AFR ~14.7 :1 . Timing seems to vary based upon load and RPM, but I generally see ~5- 8 degrees to 24 degrees. Under 'Closed loop' (when you are beyond X% TPS and bringing on boost, you will likely see your AFRs go from lean ~14.7 down to 10.XX @ redline on a stock tune. Again, timing varies, but with mine I see ~19* at redline.

Yes, it can. I began by lowering engine coolant to 190ish deg by modifying the thermostat. I also run almost all water ( very little coolant ).
INTERESTINGGGGGG....

[quote=GT-ER;5252110]Yes, it can. I began by lowering engine coolant to 190ish deg by modifying the thermostat. I also run almost all water ( very little coolant ).
The reason I ask is because I, unlike many run my secondary HE through the engine cooling system. I know I could get lower IATs by isolating, but it seems to me a modified engine is producing more heat and it needs to be delt with. I don't know much about engines. My business is anodizing and we use 2.5 million gallons of water per month. As such, I know a bit about the properties of water. Water can absorb way more heat than coolant as you know. If you are using distilled water, keep in mind that water is a universal solvent. In the pure state, it loves to dissolve whatever in can, like the metal in your cooling system. you need some corrosion protection. Hopefully the little bit of coolant is providing that. Definitely add a surfactant to reduce the hydrogen bonding or surface tension. Water wetter products do work. They are just surfactants. They allow better surface contact and therefore improved heat absorption.

How many knock sensors does the E55 engine use to monitor knock? Are the knock sensors still used after a tune to advance and retard timing due to conditions read by the sensor or is the timing a fixed value that is set by the tuner.

I have a guy (Scott) who offered to drive to Austin and tow it back to Houston as long as I paid for the trailer. He wouldn't even let me cover the gas money. I'm not sure if he posts here, but he definitely deserves to be recognized for his awesome act of kindness. 
I found a local engine in Houston that is getting picked up on Saturday and M-Power is the shop doing the swap. I've ordered the Dashdaq and appropriate sensors to be installed also. Big thanks to many in Houston, especially Shardul for being a kick-*** middle man, collecting money, receiving parts, etc. this headache would be a definite migraine without the help.
I don't know how long the swap will take, but I'm going to fly in and then drive back to NOLA after another crazy weekend in Houston. Looking forward to it.

I'm at MPower now and the new motor is here. Good luck with the rebuild. Sorry for your troubles.

Damn man, that majorly sucks. Esp. during a big trip. You have a point OP, I don't know what i would do without the kind people here either, Shardul, Outrun, Abrim, E55bullet, ALL good guys, who've helped me before. Good luck with the rebuild/replace game, can get really frustrating
always here to help! Good luck sir!

This is all I read:
the new motor is here...
Let us know, and when you get back to San Diego, we will need to meet up
Cool on the Houston Guys
Cool On Jerry
Cool on Scott....
I can hardly wait to see the conclusion of this story:
Better - Stronger - Faster!!!

On the new motor dial back the boost a notch ... fit an OEM pulley and keep the smaller S/C pulley in place...
I think these 190+ pulleys (or effectively 190+) are just reaching a bit too far for reliability....
Have to say half throttle in 5th is still allot of load on the cylinder as the gearing means the pressure has a long duration in this scenario ... its better to have motor spinning faster so the instantaneous pulses may be higher but the durations much shorter... dunno just a thought?
Could be allot of things - mbe even damage done before only manifesting now ...
Good to see u getting her back to good as new
