Picked up my new car this weekend........955hp V10 Audi RS6! (HP figure updated 08/10/22)
- Thread starter ianh
- Start date
Just booked into MRC Tuning for an "update" to my map next week. Well I say "update", what I mean is the software they used to create maps back when mine got originally done in '15 has been completely scrapped and MRC now use a whole new set which brings lots of extra options so I'm going to have a no boost "Valet" setting, Low & High boost maps which, should I decide to run an octane booster on top of the water/meth & 99RON fuel, should increase the currently "reduced until I could change the intercoolers" figure of 880hp to something more respectable 
Only a couple, it's difficult to film anything whilst remaining legal, unless you get access to a track or the Autobahn, and only morons film themselves deliberately breaking the law then post it online
There's a few others on my YT channel but these two are the most popular. Both were filmed when the car was still running just 740hp-ish. I haven't made any videos of it after the 900hp+ conversion as I just haven't found the time to make a video which would stay legal as I lived in Saudi without my car for the past 4 years, however now I'm back in the UK that should change at some point.

geez what is the top speed ?
The speedo sensor stops reading at 217mph but a few folks with 1100hp+ have gone faster than that to an estimated 225-ish. It all depends on the redline you've got set and how much power you have, but with my redline set at 7k RPM "if" I had the power then it'd top out at 250mph
All figure's for ratios from Wiki but they seem to match my video above for GPS speeds, so add about 1-5mph as the speed increases to each to match what the speedo shows.

250 jesus
Thats theory though. Doesnt mean to say the rest of the car is up to getting to 250mph. Aerodynamics starts doing strange things at high speed.
And you have to think about tyres. You will need 200mph+ rated tyres and the correct tyre pressure. This is usually 1.5 psi for every 10mph above 160mph.
You could be running on 42psi or more if going for 250mph.
Plus your tyres really should be new, you really dont want a blow out at 250mph.
even the Veyron tyres will only last 15 minutes. The veyron could actually do 270mph but in tests the tyres lasted only 4 times of 20 seconds at 270mph before they exploded. And these tyres cost £32k per set! At 250mph the tyres are fighting against 5,442 G! They have to be perfectly balanced and the tyres are even glued onto the rims.
I really wouldn't want to be doing 250mph anywhere in an RS6 even in theory the engine and drivetrain could do it.

Well you'll never slide through the Pearly Gates backwards, upside down & whilst on fire with that attitude now will you Greebo
I've found that 200mph in the RS6 is my "Oh boy, thats enough now" limit, I've been there done that and won't be repeating it any time soon. More than anything it's just a massive faff to find somewhere to do it without going to jail afterwards, and the Autobahns are possibly getting limits in the future which would knock them out.

lol true
But weird things start happening past 200mph. Even small debris can wipe you out. If you clip the dotted lines on the road at that speed, that can be enough to put you into trouble.

So that explains your absence then, it really was you in that youtube RS6 video doing 200 on the M6.
Top speed is irrelevant anyway, you can't do it anywhere really, even the fast track days the properly fast cars still can't see much past 160.
My old Mustang was geared to around 280mph, it might of hit 200mph whilst going downhill with the body parts coming off whilst doing it and as you say probably whilst turning into a fireball through the pearly gates.

Shhhh, I was in "Saudi" mate, Saudi!!!!

See @Greebo thats the spirit!!!!!
This was the leather repair on the bolster, really well done, I can't even feel any difference!
I think I might have to replace the drivers Seatbelt as it's covered in odd loking "stains" (not visible in pics) which look like (but aren't) something like oil droplets or maybe grease spots, yet they won't come out even with a steam machine on them. Really odd?

Maybe just get new belts all round in a colour you really like.
Back from MRC after a little remapping for the new Wagner IC's inc a few switchable maps - I was originally at 907hp & 1130nm with a 6500rpm redline due to the restrictive KWE IC's, then I had the map dropped to 870hp & 1100nm with a 6500rpm redline as the intake temps were getting a bit too spicy at redline and now, after fitting the better cooling and better flowing Wagner IC's I'm at 930hp and 1125nm with an increased 7500rpm redline.
Things from the dyno session - my 112k mile LP fuel pump is very close to max'ing out as it's not quite hitting the same pressure a new pump would so I'm fitting an uprated one (believe it's from a Veyron?) and the plugs & coils will also be getting a look at too, mainly due to age/heat over time (coils) and new plugs which I haven't changed in 4 years so it's always a good idea. I'll be back to MRC again in a few weeks for those bits and may get a slight bump in power too once the fuel delivery is more reliable.
Switchable Maps - Got this map which is 99RON fuel + 50/50 Water/Meth, a backup map of just 99RON fuel for about 900hp (oh no) and another map all switchable whilst driving. Plus they've also added switchable (very important to me) "pops and crackles" which is the biggest understatement I've heard in a while. These aren't your tame little OEM pops and farts; with my free-flowing exhaust these are full fledged Anti-Lag/2-Step gunfire like explosions. Happily they only happen once you let off the revs above 3000rpm and they are switchable in-car so I only have them when I want them. They've a little OTT for me but I can drive the car without them "On" just fine.

woohoo!
Did a quick 1/4 mile test using a 10hz GPS device on a disused concrete strip (old airfield/taxiway type thing) near me, it's juuuuuuust about long enough if you brake very hard at the end which, at the 150+ mph I was doing, was a little squeaky bum time as the concrete surface which is already not great is really becoming broken up in the braking area. I'll have to find somewhere else TBH as the newly found damage makes it just too sketchy I think and I should have done a "recon" of the area first as I probably wouldn't have done it had I seen the braking area first.
Did 11.27sec at 134mph with a slight engine stumble as it changed from 1st to 2nd which was worth probably 0.25 sec so with a perfect launch on a proper surface (and not cracked concrete) I think I could get into the 10's. It also did a 3.6sec 0-60mph and a 6.16sec 100kph to 200kph which would put me in with the McLaren F1
PS The elephant in the room, I know, please excuse the N95!!! As I've said before the software (Racechrono) thats on it is still better than virtually everything else available due to the completely custom nature of it's recording speed/distance etc (i.e. want to record 3mph to 127.7mph - no problem, want to record 1.7654 miles - no problem etc) however the phone screen is failing so I've just bought a Dragy to replace it which, whilst cheaper than Vbox and Racebox etc is still way more expensive than the £30 10hz GPS receiver that the free Racechrono software uses (Android Racechrono only does lap timing now, no performance tests, such a stupid mistake).

Something I noticed having done another run but now using a Dragy is that 1st just bogs down low then spins up high i.e. the torque converter stall speed can't get the rev's high enough for a proper AWD launch so the car bogs down right at the start and then, once on boost, the car then wheelspins hard into the gear change so than 1st-2nd change is slow. You actually see this happen in the acceleration graph - there's a little spike at launch followed by a dip as the car bogs, then a massive dip at 1st-2nd gear change (it just stops accelerating shown as the line dropping back to 0g) and then it takes 0.25 to 0.5sec to get back to full acceleration. I'm quite impressed by the Dragy's plotting software TBH as it makes describing what I "feel" during the event much easier to understand with a visual line to point at.
Most of the speeds and time are almost (or exactly) the same as previous so thats pretty consistent between runs using different devices, which is nice.
With all that power mate it needs to be in the 10s, is it a manual gearbox? I am sure once rolling its ballistic but the quarter mile times and 0-60 show it as been no faster than my F-Type SVR was which had nearly half the power.
Shame Santa Pod is closed, really best place for it and of course super accurate timing gear.

Yeah I agree "in theory" but practically I don't see it happening
I used a US-based "power, weight and trap speed = ET" calculator and according to that it "should" be ET'ing at <10.5sec's which sounds reasonable, but there's something in the current set-up (combination of driver skill, suspension setup, tyres, gearbox, road condition etc) which is causing that virtual "stop" on 1st-2nd gear change seen above and it's that which is the big issue.
However, away from drag strips etc it's so incredibly rare that I use WOT in 1st (basically only ever for these tests) that it's not something which has an effect for everyday driving.
Maybe time for a ZF8 upgrade.
Thats being looked at by others but it's a very long way off and, to be blunt, I'm not sure it'll ever happen as I think there's too much custom work needed for anyone to ever spend the cash req'd on it. Effectively the ZF6 isn't (and will never be) a great "drag" type box
