I have to say I get a bit sceptical when you offer which to all intents and purposes is a safety mod which now also increases power..... 
How much does the fuel rail help the starvation and how much is due to the large cap injectors?
That said the fuel delivery problem is a concern, I just dont like the solutions that have been offered as yet. The IDC maxing out is also an issue.
Mbe 180's for long WOT runs are not appropiate ... for example PLopes's car ran 181.x mph on 1 mile vmax here in UK and he has a Kleemann 168mm... and a shelf tune (plus the regualr bolt ons) ...
Looks like the tuning has to be allot more delicately balanced once you start going towards the larger pullleys. That said when I visited Kleemann in Denmark to sort out my tranny they were very surprised to see how cool my motor was running with the 180mm... but then I did have a 10gal rear reservoir and ambient temps were around 40 .... Make that a stock cooling system and 90deg ambients and I can well imagine a disaster scenario.
One other thing which is also very strange is generally its well documented these cars run rich... I think we need to identify the conditions when it does not.... is it just under, high load, long duration, WOT?

Whatever we're tuning!

The original "solution" that was offered had to do with using larger injectors to lower the IDC's which helped but didn't solve the starvation issue. The fuel feed line from the pump is also extremely small to support the extra 200chp we are making with these engine now.
Jerry at EC is the only one with an acceptable tune for the injector and rail set up. He and Shardul have spent in excess of 40 hours street and dyno tuning for this set up. I currently have 14 TTM Injector and Fuel Rail Kits delivered to clients in Germany, Singapore, South America and the US!
All current tunes are ABSOLETE (except for Jerry's) with the TTM Injector and Fuel Rail Kit.

So if kleemann reads this blown up ecu and finds out its running 29degress timing at 6k rpm there is no fuel rail kit on this plannit that would save cylinder number 8

Well, I have just read this thread.
I started to have some fears on my engine too
I have vibration around 1800 - 2400 rpm on idle if I rev the car and hold around those rpms. Is it bad?
What could cause that?
Questions off topic:
How do I know if o2 sensors was swapped R and L ? Also, how to identify dead ones if i am running catless?

Dang... you guys got me all freaked out.
I bought 930Chaos's car.. it has pretty much every mod on there. I've had that thing deep, pretty close to maxed out a few times already.. (180+ mph)... and now im learning about this number 8 hole and fuel starvation??
TTM...
If i purchase the hardware... i instal it, then you just send a "off the shelve" tune for it?? Is that the ultimate safety factor?
My car does have meth.. but just for cooling.. and with these nice socal temps... i haven't even turned it on yet.
anyway.. i guess im a bit bothered and confused... maybe we should read all A/F's off the cylinder 8. But damn it... the last thing i wanted to do is buy a sorted out car.. that "needs work"!! lol.

I said I would install it for half price, not build it...lol. Building engines is honestly pretty easy, it's just time consuming but it's not reocket science. Especially an engine as mechanically simple as the M113. I'd swap out the pistons and place forged pistons in the build to ensure I have a BETTER than OEM engine and avoid future meltdowns.
Regardless, based on the information given by the OP and the fact that he seems to not want to wait, I do agree that his best option is a used engine.

Would love to get my hands on a 55k long block to build on my engine stand.

I have had the beast back for a couple weeks now. I picked it up and drove it straight back from pompano beach Florida. I had Renntech do the majority of the work as well as a custom dyno tune. EC long tubes are on, full 3" exhaust w/ race cats and 02 relocators (car passed emissions in VA). Went from a 180 to a more reliable 168 however when the temp goes down I plan on going back to the 180. Installed a 80mm throttle body and everything I could think of on my new S55 motor such as trans/motor mounts, rear main seal, all gaskets, plugs, injectors, wires...exc
Car dynoed over 500rwhp on three back to back dyno pulls after being driven two hours straight. Temp was 98 and humidity was 60%. 507whp and 589wtq.
I have dyno sheets, videos, and over 30 photos - need to figure out how to upload them
This car is a *** monster!
The beast stands undefeated on the 1k+ mile drive from FL to VA.
Some kills:
R8 5.2 spyder
A massarati (not sure the model)
Several mustang 5.0 and one cobra
Ls6 z06 w/ a lot of mods
R6 bike
And my "grudge match" with my buddies 05 vette with 95mm throttle body, 2800 stall coverter, ported intake manifold, custom tune, kooks long tubes w/ corsa rear - smoked him!!!
We did a few 40-120 and a couple 60-140

You can upload photos and video and it will give you a quick [IMG] tag that you can copy and paste into your posts here.... works like a champ.
Curious to hear more about how the whole repair went down. Sounds like most of it was resolved in PMs.... if you're willing to talk about the $$$ involved I'm sure everyone's curious what a catastrophic engine failure really costs to fix.
Congrats on the new engine and the serious HP/TQ numbers!
