The car was on stock 21" wheels not 20s. Their car has the upgraded 21" wheel option.

So how come there aren't any "tuned" only E/CL/CLS/S, etc., Benz running iin the mid 10's? At least I haven't heard about them... I see a Rentech RWD E63 ran low 11's.

urbamworm

Gearing difference? The new awd Benz suck for launching because they can't turn traction control off and use launch control still, one guy with Renntech tune was doing 1.8s vs the 1.6s of the APR RS7. So they get sorry 60ft times and run low 11s. His mph is a little slower too but that could fluctuate with weather, he was doing 126 vs 129, but then again the gearing difference could account for some of that as well.

I also haven't looked at both cars (AMG vs RS) to know what power each is making though. I do know APR said they made more power with their RS7 than they previously did with their S8, same motor but not sure if there are little difference between them or what which also ran 10s, but it was high 10s while on their 100 octane program with a lower trap speed too compared to the RS7. The S8 ran 11.1@123 on the 93 program. So there apparently is some huge difference between the RS7 and S8 if the RS7 is trapping 3mph higher on 93 tune and running a few tenths quicker compared to the 100 octane tune S8 setup.

Renntech has a biturbo CLS63 that ran a 10.62 @136.330 and AMS has a biturbo E63 that ran a 10.786 @135.780. Both of these were the RW drive versions. There are plenty of other lightly modified biturbo Merc's pushing 130mph trap speeds. As Urbamworm stated, the new awd AMG's are probably hindered by their inability to launch aggressively. I'm sure it will be just a matter of time before that problem is fixed.

urbamworm

Rock those cars you are talking about are upgraded turbo cars though by Renntech and AMS.

As for the new S model AMGs they desperately need that launch control feature with the nannies turned off and they will be flying.

Hey David, I realize that but even without upgraded turdbros plenty of 2012+ AMG cars run 130ish traps.

We still can't even fully/properly tune 10 year old AMG's so I'm not surprised a "tune only" Audi was able to realize a larger hp increase over the new 63TT.

But it's 3.08 gearing most def is helping quite a bit vs cls63 S 2.65's

AMG E Power

Here is one for you

Thericker

That cls is running drag tires & lightweight skinny's up front & more mods than ecu only..

AMG E Power

Yes drag radials but that's it

Zod

U never thought I would consider and audi

Just need to find out how the car holds up to mods ...

TheOtherDodge

AMG E Power: That was a nice video but not what I was asking for...that was very high 10's with drag radials and front runners and who knows what else. Where is the "tune" ONLY mid 10's pass by a Benz? Not trying to argue but I still find it hard to believe (though I guess it could happen) that a "tune" only will net a 4500 lb car a drop from mid 11's to mid 10's on factory rubber, though AWD does help alot.

AMG E Power

u will never run low 10's making over 700wrtQ on street tires lol best I seen on street tires and tune only was from a e63 RWD went 11@129

Dude, please don't tell me you used C&D for stats. Those guys feather it off the line and aren't a true representation of what cars can do in the 'real world'. For instance, they claimed the C6 Z06 was a mid to high 11 second car when they were first released. We all know that Z06s are not 11.6-11.8 cars out of the box unless you are a horrible driver - which can be the case.

Then you take owners like 'Ranger' and he runs high 10s with DRs. I am sure the owner/guy who ran the RS7 is a seasoned vet or at a minimum, knows what he's doing.

My point is, if C&D does an 11.6, I'm willing to bet an experienced driver can pull low 11s. And nowadays, tunes are so impressive, running mid 10s with a tune only isn't as far fetched as people are making it out to be.

Think about it ...

Thericker

You're comparing apples to oranges I owned a heavily modded c6 before & very familiar w/Rangers driving abilities.. 1st thing Ranger's nothing short of a pro driver, from reading countless posts of his he describes his training practices of sitting in vehicle & running thru gears when its off countless times to drill it into muscle memory & make his ultra fast shifts like reflexes, he decribed doing multi sets in his garage of 10 reptions of slamming shifts thru all gears like training muscle groups @ the gym etc..

Only a very limited number of people can crack off shifts like Ranger, the average to decent driver strugles to pilot the same c6 z06 any faster than 11.50 ie mid 11's in stock c6 z06 (Majority of z06 owners can't drive stick competently enough to crack high 11's let alone hi 10's) vs Rangers high 10's...

The Audi RS7 is brand new, I only saw this 1 record pass @ 10.67 to compare to any STOCK RS7 1/4 mi data... C&D was only reputable source for STOCK 1/4 mi data I found, also MOST important #'s here are Trap speed data, it tells whole story of how much power a cars actually making + invaluable increase/decrease in Trap speeds after mods, it will not vary greatly from a soft feathered or hard launch in automatic AWD vehicles as wheel spin is nill.

Running an AWD Automatic is as straight fwd & easy as it gets (your grandma could do it if she could see over the steering wheel) there's minimal wheel spin, simple point & shoot vs a manual high powered rear wheel drive Z06, those cars are not only stick shift but notoriously hard to drive the torque management is extremely brutal & tricky to master & main reason umpteen Vettes end up in the wall @ 1/8 mile, they get squirlley as *** in a blink of an eye.. Main reason I sold mine it tried killing me on multi occasions etc.

Zod

I agree its not the ET alone that is really impressive, but also the trap!
I also agree that AWD is point and shoot, unless brake boosting is also used

60nomad

The AWD makes it easily possible and adding 100 rwhp to TT cars happens all the time with tune only...maybe they have a downpipe too but it happens with the 63's. I agree with the car goes bc of AWD and gearing as David said.


I thought this was true too and I thought that the E63 was going 10's with downpipe and tune...but high 10's not mid 10's.


Edit: Go to dragtimes.com and you can see all the real times of real cars with renntech tunes. See E63's and CLS63's for the most data, not a lot but the most. Pretty much David said it best but some are trapping 130ish. Weather means a lot to turbo's as we all know so who knows who was running at what DA as most do not have it listed.

urbamworm

Yes the tune only E63s were right around 130 for the best runs, but there is a big difference between 130 and 135 where the upgraded turbo cars are located at in the mph spectrum.

e500slr

Can we get a video of the run??!!! I mean holy **** Mid 10s with just a tune I still hate Audi but damn that is just insane If only the E55 was AWD, you just can't do without AWD after a certain mount of HP. Being able to launch anywhere on street tires is invaluable. Yes, insane smokey burnouts and controlled fishtailing is fun but even the heavily modified E55s will struggle to keep up with this new breed of dual clutch, AWD, twin turbo machines. They arrive with so much potential from the box and they can actually use their power/torque. I recently drove a dual clutch car and when I got back into my car it honestly felt like a dinosaur. Dual clutch is one of the revolutionary developments in cars. Cars like the Nissan GT-R would be NOTHING without it, that and AWD.

TheOtherDodge

I was VERY suprised the 2014 didn't come with a DCT...

gaspam

top fuel dragsters put out over 8,000 HP and they manage with RWD..... pretty sure our 500hp machines can manage

urbamworm

Yeah, just have to run a better tire on the car if you want power on the street. I do fine running around with upper 600s in my CTS-V. Nitto NT05r tires on the back.

F.A.S.T. cars are running in the nines on Stock Tires of that year, so we are talking 235/60/15 type tires!

14.00 TIRES AND WHEELS AND BRAKES
14.01 Wheels must be correct*, including correct* diameter, width and material.
Note: Width may be upgraded to a maximum of 6”, if the correct* wheel is narrower than that. Reproduction wheels OK.
14.02 All 4 wheels and tires must be same size.
Exception: Mopar TA Challenger came from factory with G-60’s on rear and F-60’s on front.
14.03 Original equipment reproduction bias-ply tires only. No soft compound tires of any kind are allowed. Retread tires are not allowed. Any car is allowed to upgrade to a maximum size tire of G-70 of the correct* wheel diameter. All cars that were originally available with a 60 series tire can upgrade to a maximum size of G-60 tire of the correct* wheel diameter.
