1/4 stage 2 not so great 3 runs all 10.6

[nickrs7]

[MileMan402]

Oh boy this should be good...

Anyways, how were the conditions?

[nickrs7]

Which Stage 2 program was this on? 104?

What were you running for fuel, VP MS109 (105 octane) or Sunoco GT260 Plus 104?

This was with the stock intake back on the car?

i ran the 104 but lanes didnt feel like they prep it good

[hubris]

Do you have timeslips of stage 1 runs in your car?

A 1.623 60' isn't all that bad though. This was with the stock RS7 intake or AWE?

awe intake i put the stock intake didnt like the way it ran so i put on the awe back on

[carymac]

Were your previous 10.6 runs with stock box or awe?

What was the DA for your stage 1 runs versus stage 2 runs?

I think the intake might have hurt your performance. If it's true that it robs power on stage 1, then on stage 2 it only would amplify the effect. I was really curious to see runs on the stock intake. Maybe next time.

What do you mean the car wasn't running right on the stock intake? I am curious since APR developed stage 2 on the stock intake. Did you log the car?

Quick question, of those of you that are running the 10.6's what other mods are you running? I know about the APR tune. Are you running any other weight savings or performance goodies like exhaust, lighter(aftermarket) wheels and tires, removing spare(etc), removing any seats? I know my car full weight with just a tune in the Florida 80+ degree heat and humidity just got into the 10's. Does the cooler weather make that much difference or are here other factors I need to consider? Thank you in advance for your help.

[Dads RS7]

DA will make a difference on any car. Elevation will hurt NA cars more than turbo cars (assuming the same boost can be made at elevation as at sea level). And turbo cars will respond better to colder air than NA cars. Your RS7's 10.9X at OSW would likely be a 10.7X at PBIR with temps in the 50's or so. So yes, weather does affect these cars a lot. Also, if you hot lap your car at the strip with little to no cool down and it's hot out, you risk seeing IATs higher than 80C, which is where the ECU starts dialing back the power for safety.

Exhaust mods have proven to do very very little to the RS7. The quickest pump gas and second quickest race gas RS7s in the country were both running bone stock downpipes and catbacks (10.69 and 10.48 respectively). I think the best and cheapest thing you could do is just pull the entire exhaust system off the car and run open downpipes. Super cheap and you'll also save around 75lbs.

BTW, your RS7 doesn't come with a spare.

Thank you, the 10.9 was on 93 octane pump gas in 75 degree, 85% humidity so I didn't think that was too bad. We'll get back out soon.

[kouzman]

DA is definitely a factor. I have had my best runs on a -829 DA, conditions which I have not met again to date. Since then I have seen anywhere from +104 DA to +586.

This is something that you should always keep in mind because in different days the car might perform completely different. Such difference can make you lose you mind! LOL!

[F16HTON]

Didn't it rain last weekend at CA speedway?

[akh23456]

you should log the car if you have the apr dongle with both intakes.

[Dguth]

Can you record 0-60 and 1/4 mile times with the APR dongle?

curious, how long did you let the car adapt to the tune/downpipes/intake/octane? I have gone to the strip many different times in various Audi's and it takes their ecu's a while to adapt properly to the change in tune/octane.

No you cannot. That would be a nice feature though!

I agree 100%

Me too. I tested this three times. Any time I go to the track and I switch/fill gas there, the car simoly does not perform as expected.

I have an event on the 24th and I will be switching to the good stuff at least 3 days before... it's funny because my wife cannot understand why I only put 1-2 gallons of 93 at a time, since I try to time it right! Lol!

Next time I would run to near empty. Switch to the 104 file and load up on the MS109 and drive 10-20 miles before and give it some gas.. Yes you are wasting 18$/gal racegas.. But the ecu will adapt. Last time I did this and let my car adapt I picked up 1.5 mph in trap on my B5 S4 APR Stage 3 104oct map.. Exact same conditions and 60ft the ecu just didnt pull timing up top.

Well I do something similar already. But usually I run the car on 100 octane, then empty, then ms109 and then switch...

Last time I hit the track I did not do that and I poured the gas at the track and switched the map there...

Who's going to the Show N Go on the 24th? It should be fun. The last two events I got to do 7-9 runs before the eliminations.

I'll be there. We can definitely meet up. I believe my professional photographer friend is also going. Make sure we'll get some good video and photos of your beast going down the track.

Have you tried clearing your engine DTC's using VCDS (even if none are showing), after switching to the higher octane? This clears the engines learned values and will much more quickly adapt to the current fuel. Otherwise it can take over 500km's to adapt.

the issue is not tune adaptation so much, but making sure that you run the correct octane as per tune... the mix hasn't really worked for me like straight racegas. plus if you actually switch at the track, chances are that there is still lesser octane gasoline in the system. We have discussed this before.

going for the ultimate time, you have to make sure that all variables are right, from car, gas, weather, etc...

500 km is a long way, the equivalent of running a full tank through the car. Help me understand why having a tune doesn't solve this problem, please. Does having a tune not affect the ECU's relevant factory settings the moment the tune is engaged? If not, why?

Weather is a crapshoot for prescribed test n tune days. You can control fuel, though. I ran my car until it was completely out of gas, then filled it with MS109 which is 105 octane. I didn't want to risk having an unknown amount of 93 octane diluting my fuel to a value potentially lower than the 104 octane tune I was running.

I've done this twice, and both times I ended up driving around with a 5 gallon jug in the car. The first time I ran out of gas on a city road less than 1 mile from home. Filled her up, cleared the DTC fault codes via APR dongle and iPhone app, and went on to add another 5 gallons of MS109 then drive around all day for 30-40 miles. The second time, I ran the car out of gas while parked at my buddy's lake house out in the sticks 100 miles from home. This time I only had 5 gallons of MS109 so I filled her up then successfully ran at a decent 1/8 mile track while dozens of 16 to 80 year-olds watched with great curiosity.

With all the talk about aftermarket intakes and how they do or don't help or hinder performance, I've come to the conclusion that for those of us who have purchased aftermarket ECU tunes we should stick with whichever intake system the tuner used when they perfected their tune. I am not saying that a given intake system isn't better than stock for whatever reason, it's just that many fuel, boost and other tunable variables are directly impacted by air flow assumptions.

I don't know if APR does anything fancy when you switch tunes, but obviously the different tune itself will make an instant difference. The main factor seems to be the timing and how the adaptations can vary this away from what would be optimum for the current fuel/tune.

I am with you on 99%. I want to fully test my aftermarket intake in order to have a solid conclusion as to the effects on performance. So far on a straight pumpgas comparison with no other variables I have seen gains...

The only differences that I can really quantify is that with the last runs, I was 20lbs lighter and I had a slightly better DA.

Even if I compare my best pre-intake run to my worst post-intake run, I still see a solid 1 mph trap gain. Which would probably be equivalent to maybe 10-15awhp...

In order to fully complete my testing, I will run the car on pure racegas (MS109) on the 24th and hopefully I will get some decent weather. But I will be extremely lucky if I actually get the same DA that I had when I did my best runs (-829 DA!!!!!). This can definitely be a factor!

Then I can definitely decide if the intake is a benefit or not. Of course I will post my results, regardless of the outcome since I have nothing to gain from not posting. I might even take the stock intake with me and if I see major issues, I might literally swap it at the track and run again! It is not difficult to change intakes at all!

Man, you understand the scientific method and I look forward to your results. For some reason on my phone your links to your runs look like gibberish.

LOL. I just copied/pasted from my excel spreadsheet that I archive all my runs since I got the RS. 47 runs to date since I bought the car and 24 of them in the 10s!
