800rwtq Biturbo E63!
Today I took a half day and played witness to MHP S2 Biturbo E63 being flogged on the dyno. I have one as well so it's nice to see what it's capable of without beating mine up--thanks Andy for taking one for the team 
The first 2 passes resulted in a screwed up tach reading and wheelspin, the next 6 the guys spent time testing unloaded versus loaded and ended up diagnosing a defective inducive clip or coil pack interference, I left before that discussion ended. That did not help the heatsoak situation as the fans at Brians dyno aren't great.
After swapping clips (always have a back up guys
) the car laid down in succession 785, 795, 805rwtq. It wasn't the other way around despite the car already being hot. rwhp was in the 630 range today, given ample time to cool, better air, and some decent gas I think this thing may hit 650/810rw? I dunno but again am glad I can watch and enjoy with no risk. 
There's a clip on youtube showing the tach on the computer screen going nuts from the interference, it was weird to see sometimes the tach would read correctly then it would jump to what would be 12,000rpm. I believe their redyno next week will be a race gas affair.
All I can say is on my 20s I spin at 100mph in 4th gear like nothing and am enjoying everyone push out some insane numbers from these cars. Thank you AMG, with a tune and full exhaust literally just boltons that's 950lb/ft of torque at the crank. Wow!!! Torque like a diesel baby!!! Whoohoo!!!!

IIRC whp was 632 on the best pull. Keep in mind the same car has already made 642rwhp so I really think the lack of cooldown between 12 pulls in one and a half hours hurt the HP.
I'll post a full graph next week after the next scheduled dyno session. They blocked off a half day vs a few hrs. The first 8 runs were literally wasted, video'd but useless as you can see the tach jump around on the screen from electrical interference. After they figured out the clip issue they made 3 solid pulls and wanted to let the car cool and then go for gold however they simply ran out of time. I also don't think Andy wants a 632rwhp graph out there when they've made 10rw more already. Full vids and graphs coming next week. I'd love to see 650 and 810 but who knows. In the meantime I'll look for a trunk mounted gooseneck hitch so I can tow my 44 footer with the E lol

Yeah, those M157s are ridiculous! I've been reading that they might be putting a detuned verison of this motor in the next gen C63 with 4matic like the refreshened 2014 E63. Does anyone know any truth to that? If so, that car will be a legend!

These cars just have an ECU tune and a full exhaust for mods. It's the 5.5L four valve M157, not the naturally aspirated 6.2L four valve M156.

Here are two of the initial wasted runs in which you can actually hear the turbos spooling via exhaust due lack of compressor or other air line noise in background.
No pulls but a sweet sound.

Can't you just post the dyno that had the same 805wtq with whp you are talking about? And next week you can post the final dyno, just so we can see the difference.

I've told you why twice now but you don't seem to want to accept my answer.
It's not my car, it's their record and I can see personally speaking why they wouldn't want to post anything but the best number the car has laid down. It was too heatsoaked to beat it's previous best HP wise which it will this coming week so please have patience. I believe you'll get to see vs tune only and vs stock too. Will be nice to see all that info.
They were debating on whether or not to even post the rwtq numbers but I'm glad they did. Pretty nuts what these new motors are capable of.
Worth the Wait, I'm not sure we'll see any tuners divulge boost and timing numbers but the car was on 93 octane pump gas like mine so it can't be off the chart.
Capn, yes that's exactly what I said. Those are M275 type torque numbers. Thankfully the M157 holds power and tq much longer rpm wise than the v12s. Both awesome powerplants in their own right, AMG rocks!

LOL so how did the word "problem" get tagged to this thread?
Moderators care to chime in?
I don't see any mention of any issues and I sure didn't add that tag.

Careful what you wish for
Next week will be more dynos, then new 60-130s, then 2-3 weeks track time.
They already hold the 60-130 record for a Biturbo E63 even with steel rotors, stock tires, stock air filters, stock wheels and pump gas. No race gas, ceramics, lightweight wheels.
With DRs and colder air vs the last summer test I expect 60-130 numbers to drop like a rock.
I'm not a ricer or benchracer so I won't guess at track times, just don't expect to see an 11
