I don’t think the SC is anywhere near as able to deal with DA as the turbo cars…but I also don’t think it’s anywhere near as affected as an NA car is.
I am sure it is a factor, but I’m not betting on much. I watched a stock DSG car run 13.1-13.2 about 9 times in a row on a hot summer night where my old S4 was struggling to do better than 13.30. My S4 ran 12.9 in good DA. I also sawa stock DSG B8 on that same track in good DA run 13.1-13.2. The fastest bone stock DSG cars in good conditions have run what…12.9-13.0? These aren’t huge differences.
ilspazzaneve ran something terrible (for a b8 S4) like 13.30-13.40 when he was stock, also at the same track as I go to. Wonder what his conditions were? We all know his car is awesome because just tuned he ran low ass 12s on race and 12.4 on pump.
In any event, that piece of bench racing turned into timed acceleration data by tsivas27 last night was AWESOME! You guys are lucky to have that dude on the platform. I love the way he gathers info, and his presentation is great.
I think it’s extremely important to clear up one fact… It was a 25mph tailwind not 30mph! Lol! Seriously it was!
Okay a few other points:
My 11.9 run was on race gas and I was running the race file however, there is a calibration period with these tunes and I firmly believe the tune was not fully calibrated.
Looking at Kavan’s results on pump gas the best he could achieve that day was 12.4x but after switch to race gas for 3+ hours and 20+ passes he was able to knockoff 4 tenths to achieve 12.0x.
Now if we were to compare my experience on race gas we see that I picked up 0.5-1 tenth going from 12.0x to 11.9x (no where close to Kavan’s 4 tenths). I think it was the lack of calibration time on the race gas file that held me back from running any lower than what I ran. I only made a hand full of passes over the course of <1hr. My last pass, though not the best ET, trapped over 117mph and the car continued to feel stronger as I drove it home.
Wheel weight - my wheels weigh in at about 18.5ish lbs per corner. Now my tires are anchors and bring the total weight per corner to 44-45lbs. (I really need better tires)
I agree 100% the tailwind was a factor, how much I don’t know, but it would be an interesting stat to keep, as I don’t believe any other runs detail anything weather wise other than the DA (which in this case was +550 which, if I remember correctly, was not as favorable as the time we hit the strip with George and the other B7 guys)
I however do believe Primetime’s car is just plan faster out of the box than most, if not all, B8’s. I also do believe Ron is a great drag racer who really knows his Sh*t and that he is instrumental in achieve those great times!
At this point all I want to do is get back to the strip on the 7th and see what my car can do without a tailwind being an “*” of the time.
Saki, I hear you… maybe my term “huge” was incorrect… Also, as you well know there is more to it then just DA… the DA could be great but if you sit in the staging lanes with the car running for 15 minutes your IAT’s go way up, timing gets pulled, and you run slower… My best times have come when “hot lapping the car” but no time sitting around… IE decent DA(500ish), car cooled down and then make 2-3 back to back passes w/o really stopping which is how it is in the late fall… this allows the air to keep the HE cool… I can only go off my experience since I can’t get others down here to hit the strip with me, so honestly you have seen more of these cars run than me…
Yeah tsivas is the man and I love his data analysis… All of the good B8 guys are here sharing which is great…
That is explainable as we know the valve opens at 5000-5500 rpm to release boost pressure under normal operating temperatures. With the increased stress of high ambient temperatures and multiple passes I bet the ECU kept the valve closed deeper into the rpm range and as a result maintained boost pressure resulting in similar performance ET wise between the runs.
dude that’ll be a 50 mph tailwind before long. My memory sucks when it helps me make a point
From the time you made the passes with us, to the time you went 12.0 and 11.9, what did you change…just an intake? If you want my opinion, an intake is going to add very little MPH wise. If you’re lucky? 1.0 mph and a tenth…and that’s a big if. Take your 12.0 @ x to 12.1 @ x-1 and you’ve got a ballpark idea of your time to compare to the day you came with us which was 12.39 @ 111. We had better DA (around 0 to -300 I believe) too.
Bear, Very good points and thanks for the nice comments… Like you I just want to hit the strip regardless… I just hope the cars that said they will show do show on the 7th… Will make for some good vids!
Saki, Yes the car can still maintain boost if needed… There have been a few threads on this on the other forum from some of the CO guys…
step 1: get a pbox
step 2: try not to get arrested while using said pbox
I have one…we could get some data on your car and ilspazzaneve’s car. Would be an interesting comparison as he has chosen the supersleeper bone stock ‘look’ but just software adjustment while you have just about every mod possible except cooling.

That may even be generous as I don’t think he has drag raced… I just wanna see how I do against S6atron and his B5 and the Imolamonster ;D
If you beat the ImolaMonster by 5 tenths or better, he has to change his name to ImolaKitten. If he beats you by even 0.001 (on your respective bests of the day) you have to change your name to SecondTime.
thanks boys. compliments are what makes me keep doing this stuff. that and my OCD with data collection.
I will be doing apexit’s car soon and see what that 10.87 60-130 time with 2.9% decline is where we test.
Also am trying to get a DSG APR Stage 2 car to run also and see what times are without the shift factor we are seeing so much with the 6MT.
I will also be vag logging Dave’s Revo car and Pete’s again to readdress this timing thing and get a better sample size on 93 pump gas than just one damn car. Got some tips from Jason on what to do.
Also Pete is getting 100 tune Thursday so we shall see what he runs with race gas. Gonna do some quarter mile simulations and then some highway pulls.
Yeah Bear… road choice is important, like the roads in Mexico we use. And proper leo detection/spotters. I am methodical with my runs and area is triple checked. Not many cars go by so it’s easy to do.
And I’m still kind of pissed no damn GIAC guys will chime in or ask for help or participate. I am willing to vag com, do whatever… and I know there are guys in NY that have it. Just weird… no one showed for track day, no one participates with vag logs… and it’s crickets when guys get together to compare acceleration runs.
I am excited to have fun with you as well…Car is getting tuned as you are reading this…
How do we want to do it pump vs pump and race vs race or are we both just on kill mode and race eachother? Hopefully with imolaKitten trying to figure out how to catch up…
you guys will need to go with one tune in mind…otherwise adaptation will fuck up your results.
Just decide to be there race…or pump.
Pump is far more relevant to me…but that’s just me. I don’t think saying a car that runs 11.999 on race is nearly as relevant as seeing what it does on pump…which is what it will run on the road…when I come across it and have to race it.
Saki, I am game on the name changes… Not sure the kitten will be though… lol
S6Atron, With such a small window for me in the spring, good weather wise, I would prefer to run race gas and try to improve on my 11.79… I’ll watch the weather leading up to it and if it is going to be really warm or a bad DA we can go pump… There are a few stations local or I could bring some with me so let me know… car hasn’t run on pump gas since it had around 2,200 miles and it has 5,700 now… lol I drove the car this past weekend and got gas… only $6.59 a gallon…
I am the same way I am a complete retard on the fuel, today i filled up Boots 335 on 100oct at 6.79 only 15 gallons hahahaha… My Audi will have a ton of 116 running through it. I am ordering my 55 gal drum shortly!
I wish it was 110 I get a smoking deal on that! We go through a BUNCH of that in the summers! I have been getting that for 5.25 per gallon.
That only happens when you make a few passes PrimeTime and I are expectying to make 1000 ± 10 passes that day! No stopping and at least 4 tank fillups! If we cant burn throught the last tank we will drill a hole in the gas tank just to disrespect the fuel!
hahahahah
in all reality when you make a few passes your car should adapt over plus I am going to have two ecu’s so I am good!
