Congrats on the RS7 man, Sepang blue is a drool worthy color!

I strongly considered a 2016 RS7 before going with a 2017 C63s coupe, but ultimately didn't want to be in basically the same car as an W212.5 E63. Be careful launching that beast with Stage 2, they are prone to popping axles like twigs, but aside from that the Audi 4.0TT and ZF8 are bulletproof.

Ooops - you're right.

kponti - sorry!

Well, yeah, of course it's design? Tire choice is like step 4 of building a car (though diamter of the 275/30-21 is 27.5 vs. 26" for the 285/30-19) but that misses the point I was making Rolling diameter matters, a taller tire rolls over things a shorter tire falls further into, and can deform more longitudinally over rises, meaning bigger wheel movement rolling over the same bump or dip, plus the 5P is just sortof crap compared to the most modern summer tires. Then Merc uses a tiny tire on a heavy powerful car that can carry a lot of crap and tax the tires for long periods at high speeds and says "yeah...you're gonna want to max out the pressure or you might die" which doesn't help either

If it's poor design, poor design of what else? The suspension has plenty of compliance and lots of travel. It's squishy and absorbs the bigger hits just fine, I don't think it's running out of travel or whatever. I really think they were hemmed in by the tire choices forced on them by the brakes and unibody space limitations and had to compromise around them. And I think modern summer tires are a hell of a lot better than they used to be and might make enough difference to matter.

Ok....the update you’ve all been waiting for. Well maybe it was just me but I finally got to the track with the stage 2 RS7.

First I’ll preface that DA was horrible as always, averaging 3000ft during my runs. My best runs in the E63 were at 1500ft DA and those were 11.19s @ 126mph. When I had the E63 there were no personal tuning options to allow me to run race gas so the RS7 does have that advantage. But that’s not Audi’s fault and one of the many reasons I jumped ship. Trying to learn a proper launch technique is certainly easier in the RS7. It doesn’t find limp mode anywhere near as quickly as the E63 did when brake boosting. But I am still learning. I was also on significantly lighter wheels in the E63. The RS7 is on stockers with worn 21” Continentals. Anyways she rattled off consistent 10.4s @ 132mph. And Dragy was within less than a tenth in time and just over a tenth of a mph. I’m thoroughly impressed by it! 60ft times were all low 1.6s. Pretty good for my first time but definitely room for improvement. The E63 also has meth/water injection which I plan to do with this car as well in the near future. So I think there’s easy an 10.3 in her, maybe a tiny bit more with minimal effort and cooperating weather.

PeterUbers

Do you mean you ran 10.4 @ 132?

chiromikey

Lol, thanks, I’ve been stuck in the 11s for so long that I can’t even type 10s!!

Celicasaur

Is that 132 on pump fuel or race fuel??

Either way, holy hell, thats unreal.

Gosh I think back to the 90's or even the 00''s when to have a car that trapped even close to 130mph, it would involve $$$$$ and end up in a car that's only good for drag with a big laggy turbo

PeterUbers

thats crazy awesome man... glad this Audi has made you whole ... I'm sure you'll get lots of fun out of it

keep this thread going and let us know how it's going

chiromikey

Yes, that was in the race gas tune. Thanks!

i remember when 14s were a top notch street car and if somehow you built a car that got into the 12s you were an elite and untouchable! I say built because you literally had to build a motor, trans, and 3.73 or lower rear end! And you’re right, it costs money! Not like these cars don’t but to slap a tune on and run mid 10s in a 4500lb sedan is crazy.

chiromikey

With our DA I honestly was just hoping to touch 10.8s. This is where the M157 should have been (and what we were promised by all the tuners) years ago! Thanks bud!

Celicasaur

FML I still have cars in the 12s and cool as they are, in 2019 it just doesn't cut it really.

Question: your 60-100mph time with pump fuel vs race fuel...what's the difference? Is it just over 3 seconds on pump fuel and around 3 seconds flat on race fuel?

chiromikey

I haven’t measured any 60-100mph times so I’m not even sure. Driving to the track on race fuel was a bit misleading. I really couldn’t feel any difference so I wasn’t expecting to start knocking off 10.4s.

Celicasaur

How does it work, do you have to upload a race tune file, or does it automatically detect the higher octane after some WOT pulls and then starts to run higher timing?

chiromikey

I can change tunes through an APR phone app or through the instrument cluster if something happened to my phone.

kponti

Wow congrats!!!
I am sure this is just the beginning and there is more in the car after you really play around with it.

And damn you for further confusing my choices!
I like handling though...... And the RS7 reminds me of the 2014 to 2016 E63s in the pushy portly feel only is much smoother on the straights.
Maybe my only choice should be the new AMG GT63s lol though that will still not touch your car at the track. Wonder what the new RS7 has in store.......

But seriously this is hauling! Do you think you will push for 9s?

chiromikey

I think you’re right about more being in the car, especially at a sea level track. There aren’t many tracks slower than ours. I’ll have to wait for winter to get better weather since our DA is about to skyrocket over 5000ft. And when I say better weather I’m only talking about DA dropping under 2000ft but if I can get a 10.2 with minimal to no other mods besides lighter wheels and decent tires...I might actually try for 9s.

The GT63s are absolutely beautiful but so over priced for a CLS platform. I definitely don’t see how a facelift could have put it into full blown Porsche Panamera category! Rumors are there will be two RS7s, one with 650hp and a hybrid borrowing from Porsche with over 700. If you’re into handling and straight line performance the logical choice is the F90 M5 (or hopefully M6 Gran Coupe). It does everything better than the W213, comfort, handling, and tuned performance. You can get over the bland styling with minimal aftermarket body upgrades but you’ll just have to be ok with the lack of decent sound from those BMW engines.

kponti

You are absolutely right about the M5, but also very right about the BLAND styling. I have looked and looked and looked and I still do not get excited. I think the M6 is no more, but that with the F90 hardware would be worth looking into

FastWgn

And there is no wagon....

chiromikey

Nope, for now at least, you’re stuck with an E63.

Roverron

@chiromikey do you think the lack power gains in tunes is tuner or software related or the the Audi's just have a better platform to work with? I mean your saying you can change tunes from a phone app or dashboard I haven't heard anything like that in the AMG tuning world.

chiromikey

The lack of gains are both software and tuner related. The software encryption is too difficult for tuners to crack so they can’t access everything and are limited in what they can actually do. The only thing significantly better in the Audi drivetrain is the transmission. AMG insists on building its own transmissions as if they can do it better than dedicated transmission builders.
