2018 TTRS APR Stage 1 E85R Performance Figures - UK

[Cbhoy24]

Hi guys,

I have a 2018 Audi TTRS with the APR Stage 1 tune. Just for information really but thought I would post the standard figures I managed to achieve in the car followed by the APR Stage 1 E85R figures.

The standard car was completely standard as it left the factory with 1000 miles on the clock.

All the times below are dragy verified.

99 octane (93-94 US) Full weight. Standard 20” and Pzero’s.

1/4m = 11.53 @ 120mph
0-60mph = 3.44
0-100mph = 8.10
0-130mph = 14.02
60-130mph = 10.55
0-100kmh = 3.62
0-200kmh = 12.69
100-200kmh = 9.07

I then fitted the Forge FMIC, a 4” DP and a K&N Panel Filter and got the APR Stage 1 tune last week. The car made 500bhp on the dyno on the 99 / 93 US file (+100bhp up on stock 400bhp, sorry I don’t know whp figures).
I didn’t get dyno figures for the E85 file.

I bought some Sunoco E85R fuel and switched the maps and the same metrics are posted below...

APR Stage 1 E85 file :- Full weight, Standard 20’s and Pzero’s. Car now with 2000 miles on clock.

1/4m = 10.58 @ 132mph
0-60mph = 2.90
0-100mph = 6.24
0-130mph = 10.24
0-100kmh = 3.02
0-200kmh = 9.37
100-200kmh = 6.24
60-130mph = 7.34

All times with part throttle limited launch control on standard 20” wheels and Pzero tyres.

As you will all probably appreciate on a Stage 1 tune, the Pirelli Pzero’s on a 30 sidewall are impossible to launch (even with 20psi) on full throttle launch control. The profile is too narrow and the sidewalls are too stiff, there is no crumple in the tyres and as such any attempt at a full throttle launch resulted in spin, hop and short shift and a 2.0 60ft. The only way is to part throttle launch the car until it’s moving and then full throttle as soon as it does. This results in a better mid 1.7 60ft.

APR have posted it on their FB Page this morning with all the verified Dragy charts. Sorry, I don’t know how to upload to here from my phone. Also, they are posted on Scottish_audi_rs on instagram

If someone wants to grab the Dragy screenshots from FB and upload them here, you are more than welcome. If not, the links above are more than sufficient.

I’ll be honest, I’m over the moon with these times, to think the car is still on Stage 1 with Stage 2 and TCU still to be tuned for. In addition to that, these runs are full weight and on the standard 20’s and Pzero’s which I’ve already highlighted limit launch and done on the street not on a prepped track.

Absolutely incredible platform we have here.

Congrats on the awesome run. I have a question for you. What do you mean by part throttle launch control? I thought in order to activate launch control, you have to put the gas pedal all the way to the floor? Is the TTRS different? Can you activate it using only part throttle?

Congrats on the awesome run. I have a question for you. What do you mean by part throttle launch control? I thought in order to activate launch control, you have to put the gas pedal all the way to the floor? Is the TTRS different? Can you activate it using only part throttle?

Yes, you can. If you put it to the screens with the power/torque and boost gauge.

You can part throttle launch (50-75% pedal) to hold revs at between 2500-3000 and still build boost up in the boost gauge. The trick is to get around 2750rpm, build boost until it gets up to around the B of the word BOOST, and then release brake. If you go full throttle so revs are at 3500 and boost climbs to ST in the BOOST gauge and release (applies to the standard Pzero’s) the tyres will spin and hop and the car will short shift. The 60ft will then come in at around 2.0 and your run will be ruined.

Part throttle in the way I have said above and release at moderate boost and moderate revs will get you off the line cleanly where you will then go full throttle and you’ll pull a 1.75 60ft. It’s as good as it’s going to get on the Pzero’s.

The 30 profile of the Pzero’s does not help, they’re solid and there’s no give in them. Fit 35/40 profile PS4’s and those are soft, the tyres will crumple on launch and dig in, this will allow you to run a low 1.6 off full throttle launch. Tested this last week with a buddy in the RS3 Sedan same tune same mods. He was on PS4’s and I am on Pzero’s. He was able to launch full throttle every run, I was not.

So there’s definitely time to be had by switching to a much softer tyre compound with a larger sidewall.

You can see this in my dragy charts, the G off launch barely reaches beyond 1g peak. Full throttle launch would spike that up around 1.3.

Thanks for the detailed information. Are there any Dragy results for your buddy's RS3?

[Cbhoy24]

Yes, view Audi 1/4m July and then you will see me in 2nd place and him behind me in 3rd place. Have a look at both charts, look at his peak g off launch and then look at mine. He has actually managed to get a best of 1.63 60ft off his PS4’s on the street. He’s listed as Pzero’s on dragy on that run but he’s not, he’s just not changed his template for his car.

Here’s one of his runs on the website of our dragstrip

https://www.crailraceway.co.uk/wp/sh...16%3A17&RID=33

60ft showing 1.64 on that run. Will probably need TCU tune and adjustable LC to dig in quicker. Or a set of Hoosiers.

I think I see now. So you're referring to runs that were done both on the street using Dragy as well as at the dragstrip? Your best Dragy run is 10.58 and your best run at the dragstrip is 10.75, is that right? Did you have any different mods for the 10.58 run or did the car just hook better on that run on the street than on your other runs at the track?

[TTRSleeper]

Was the RS3 full weight for his 10.6 runs at Crail Raceway?

[Cbhoy24]

Yes, that’s correct, I managed a 10.75 on Sunday at the dragstrip but had to cut short due to low fuel. It took me a while on Sunday to learn and master a part throttle launch. There’s a little bit of pressure on you at the dragstrip with spectators and the lights, the other lane etc. It was also a very humid day on Sunday at around 70%.

I then topped back up with E85 and a cool morning on the street and done the 10.58. I was able to take my time with the launch with no pressure and I’ve now mastered the technique. (It’s not easy) - I hadn’t fully mastered it on a Sunday, I was trying all sorts. ESP off, ESP sport etc, full throttle, no throttle and roll, different part throttle hold and releases, different tyre pressures. By the time I done the runs this morning, I had everything mastered.

Yes he managed a 10.63/64 at the dragstrip and on dragy (within 1/100 of a second between the two readings)

Yes, he was running fully stripped, seats and carpets and tools out. I was running full weight.

There’s certainly more to come off those times of mine.

Ahhh, that makes perfect sense now. I was going to say that relative to your car, even when factoring in his stickier tires and better 60' his car still seemed a little too quick at 10.6s. It makes sense that his car was stripped. It's also interesting to note that the published weights for the UK TTRS is 1440kg and 1515 for the RS3 Saloon. That's only a difference of 75kg or 165lbs. Here in the USA, the difference between the two advertised weights is 127kg or 279lbs.

Did you use Dragy at the dragstrip? If so, what did it show for your 10.75 runs?

Does your buddy with the RS3 use your same launch technique or is he able to use launch control with full throttle due to his stickier PS3s?

When you say he took his carpeting out, do you mean from his boot? Or did he really take out the carpeting from his interior?

[TTRSleeper]

Do you have a 60ft time from your 10.58s Dragy run?

[Cbhoy24]

Yes, it’s listed on the Dragy display, 1.75. As good as it will get on the Pzero’s Stage 1 E85 file I would think.

[Cbhoy24]

My Dragy run out of battery at the strip early on so I didnt get the Dragy runs from the strip.

Yes, no carpets in the car at all. But window motors and catback etc still on the car.

The reason for the 1515kg vs 1440kg kerb weights is due to the standard RS3 Sedan in the U.K. having Pano roof as an option, not as standard fit. I believe that is responsible for 35-40kg alone.

He was using full foot flat to the floor with no liftoff at all in his launches on the Michelin Pilot Sport 4’s on lightweight 18’s.

[TTRSleeper]

Yeah the US cars come with the pano roof standard with no way to even delete it! Ugh! I don't know how much weight it adds but I do know that the complete sunroof assembly on a B5 S4 is around 14kg. The pano roof is a lot bigger than a standard sunroof right?

I'm anxious to get the APR E85 tune on my car and make some passes. I'm waiting for the next sale.

[Trent212]

Can't wait to change over to the E85 tune my self, got some tires I'm waiting to mount up and will be ready to rock!

[TTRSleeper]

Nice, what kind of tires did you go with?

[Trent212]

Got some Bridgestone RE-71Rs off my S4, going to use them up and get some r888s probably.

I forgot to ask, does he have the pano roof option on his RS3? Or no sunroof?

[Loe]

that's flying! Glad you figured out the launch on the OE tires/wheels

No Pano roof

Just ran a 1/4 mile with my car using my Vbox Sport. 12.4@113. Pretty disappointing. How did you get 11.53@120 lol? My car only has 127 miles on it. I wonder if the ECU is limiting power until it gets more miles on it?

ttrs_vbox.jpg

EDIT: I wonder if the dealership filled the tank with standard fuel and not premium?

[Loe]

being in Miami this time of year pretty much is your answer, plus why is your 60ft so slow? No LC?

Are you intentionally ignoring the break-in period (your car, do as you please, but you definitely are not supposed to be running it hard right now)? You should wait a while before doing 1/4 mile passes. Check your owners manual...

Also, I ran 11.7s stock in San Antonio, with some wheel spin due to bad track conditions. Who knows what's up, run your tank down then fill up, but I would suggest waiting before you go crazy with it.

[TTRSleeper]

The owner's manual is for the TT/TTS. Those cars have mass produced engines which do require a proper break in. Nothing in that manual is specific to the RS. Ever notice how the RS cars are shipped to the dealer with 30-40 miles on them? That's because all RS cars are broken in and tested before leaving. They don't require a traditional break in.

Can you post your 11.7 timeslip? How hot was it outside? Thanks.

That was with LC. I ran again last night and did a 12.16@114. Still seems a little slow.

I won't argue with you, but the break-in applies to all cars. All cars have the engine run-in a bit from the factory, but that doesn't mean you go rag on it new. Some people subscribe to the drive it like you stole it break-in method, but not myself. Either way, here is my pass, with a time slip, density altitude (what I assume you want in addition to temp) and a video of the pass.

Raced myself (about 70F outside), so ignore RT. Stock with 1/2 tank of fuel and myself (3500lbs on the scale). I had a little wheel spin, but still managed an 11.7256.

Density Altitude: 1728 feet

For 99.9% of the cars manufactured today, I'd agree with you. But certain cars like the RS, AMG cars, etc. are an exception. They're not "new" engines per se and have been fully tested and broken in by the manufacturer's specialty division before being shipped. Think of it like a race engine. When you get a race engine built by your race engine builder of choice, it too doesn't require a break in. It also makes more power the fresher it is.

How many miles were on your car when you ran the 11.7?

Can you check the timeslip link please? It's not working. Thanks.

I live at sea level, use 99 octane pump fuel (93-94 US octane) and with a temp of around 55f. The car when I run 11.5 @ 120 on dragy had about 1000m on the clock. The car was run from cold with no boost until engine oil temp got upto over 80c (175f). At that point, I lined up and let rip. Tyre pressures had around 35f, 32r

Your 60ft for a start is very poor, there should be no traction issues in a stock car. ESP off, dynamic and S. Hold launch for about 3secs and release. Find a quiet straight stretch early in the morning when temps are at coolest and make no steering inputs if you can do so.

I’d be very surprised if you didn’t come down towards 11.6-11.7 @ 117ish. Running cool and at sea level definitely helps.

And yes, likely the dealership have put rubbish fuel in the car.

Thanks for the tips. This was my first test blast and I think I stayed on the launch control a bit too long. Just didn't seem like a clean launch. I tried it again about an hour later and ran 12.1@114. So we're getting there! As it breaks in and I'm able to get some better fuel in it, I'm hoping to break into the 11's stock. It's always hot and muggy down here in southern FL so that's one disadvantage I'll always be at, except for those rare nights in the winter when it can dip down into the 50's here...

127 miles! transmission and breaks take around 500 miles to break in. not a smart move, I hope you only ran it once.

my best stock run 11.50 @122

That's already been discussed ad nauseum over here: https://www.audizine.com/forum/showt...id-I-get-a-dud

Let me guess, your 11.5@122 was at Napierville in negative DA right?
