That I know of yes but all other times where done at the track so it’s not a direct comparison .but hell of a time and trap speed for a boat .

Great numbers. But as Juan stated, cannot be compared to actual track numbers
While not an "official time" it is accurate. Dragy has been proven to be within 1/100 of a second.
Plus the run was going up a .45° incline.

That’s very impressive. Can’t wait to see if it holds similar time on a track — I bet it will!!
Are you able to log critical data with your tune or some OBD gizmo. Coming from a tuned N54, that was very typical.
It would be good to see how your fueling is on e35. BMW had challenges with HPFP keeping up, so we’d run an additional LPFP in the tank to feed the HPFP (my layman’s understanding) as we hit E30 and higher so as to avoid lean AFR.
Really impressive!

I suspect it’s E85 fuel from the pump blended with ordinary 91 or 93 octane to bump octane up to or near 100. N54 BMW guys have this down to a science. On a full tank, an e35 blend probably has 6 or more gallons E85 to blend to a total of 35% corn juice.. that then raises octane substantially, which allows more timing advance, and more boost holding all else constant.

So E35 is the % of E85 to 93 octane and not an actual type of pumped gas [up] Back to my search for the best price on the Autotech HPFP [evilsmile]

Correct, it's a blend. Regular pump gas is typically e6-e10 while e85 pump gas is usually e60-e90. Because of the variability, it is wise to measure ethanol content if you plan to blend repetitively.
You can do so by purchasing an ECA kit like this (which I've done)
http://www.zeitronix.com/order/order.htm#ECA (middle of the page for full kit labeled, Ethanol Content Analyzer ECA-2 Kit, $349)
Or measure manually with a kit like this (would be a pain in the ass to do each time as even the same pump will vary is its ethanol content)...certainly cheaper, though. Does require easy calculation after measuring ethanol in your pump gas and your e85.

That's where logging comes in. You don't want fuel pressures or AFRs outside of what the tune calls for. Clearly, you don't want misfire and, some would argue, if timing is pulled a lot --- but not misfiring --- you should make adjustments. Talking with the guys at APR to see what they think about e35 on their 100 octane map would be a good idea. Being aggressive is great until it's not.
Yes. Just curious if I ran straight e85 would I be able to load the 104 octane tune. E85 is supposedly 105 octane or equivalent.

Right, but need to make sure your fueling system is adequate.
I ran full e85 on my B8 S4 by simply swapping the HPFP. BUT, I was running an EPL file specific to e85. I don't know for sure, but would imagine a 104 file from APR may differ from a specific ethanol tune.
Yes. Just curious if I ran straight e85 would I be able to load the 104 octane tune. E85 is supposedly 105 octane or equivalent.
No, the file won't work with e85. E35 will work with 100 file and e50 with 104 file. Both have to have an HPFP to support or you'll run out of fueling.
You'll also need to log to make sure your car is happy with it.

Sent from my SM-G920F using Audizine mobile app (http://r.tapatalk.com/byo?rid=87676)
Great times! Dragy is 99.99% accurate down to the 1/100th of a second. I actually covered this in the B8/B8.5 section a while ago, I'll have to dig up my examples from dragy vs timeslip.
For anyone questioning the validity of the time I got permission from Loe to share his time slips. Loe is the pioneer for pushing the 3.0t and probably the most respected individual for the platform.
The times are accurate. The only difference is dragy gives actual speed at the end of the quarter mile vs the trap speed.

Wasn't questioning the validity. My first thought was the "trap" was too high since all performance gauges I'm aware of calculate top speed of the run rather than a trap speed.
I still say you visit the track to set some records for your platform. This device is giving you a solid idea of where your ET should be with a trap that should be in the 118 range

quality GPS based meters will indeed show near matching results to your timeslip as my Gtech Pro was usually spot on accurate on all the passes i made using it, often to the 1/1000th - only problems arose when satellite connectivity was mediocre or my car lurched some after I set the meter (a consequence of brake boosting vs. having LC). I think what some are saying is that despite it's apparent accuracy, Loe has actual time slips as backup, in and of itself the metered results don't suffice as proof of your car's 1/4 mile prowess. It very well may turn mid-11's and all this will be moot, but until you do that the metered results are just guidelines rather than solid proof.

The Dragy will show "weak GPS signal" or "invalidate" the run. It only shows a "valid" run when it has 2 solid GPS signals so it takes the guess work out of it (thankfully).
He really should try the 104 file, there is about a 8* difference in timing across the board, and that file (at least on the B8/B8.5's) has more flexibility built into it for higher ethanol content. I actually think he'll hit a 120.xx mph trap on the 104 file personally...
Just ordered the dragy off amazon today. Will have it tomorrow. Can’t wait. Lol.
Finally got my dragy today...did a few passes in less than ideal weather and not launching very hard...VERY HAPPY with my times considering my mods. With the 104 octane and tune I know 11's are going to be there for me.
Mods are in my sig...

I know it says Dragy, but the majority of people who see that may think if they modify their cars similar to yours, they can trap 120+ in the quarter, which is likely not feasible. We had the discussion about trap speed vs top speed, and while you may know the difference, majority likely do not. Not trying to give you a hard time, I just don't see the benefit of posting a performance device 1/4 mile that doesn't give apples to apples comparison of a drag strip (more so in the trap category than ET). If you ran a different metric such as 60-130, that would make sense to throw in a signature since that is a great data point for acceleration [up]
The weather has been shit in Houston too, so much rain! I've had my last 3 track dates cancelled due to weather here so I'm packing up and going to Florida this weekend to run in the sun

I agree with with you are saying so I removed the speed. Most probably aren't aware of the difference in how the strip measures the average speed over the trap vs the speed at the actual moment of distance traveled on dragy.
Hopefully no rain next weekend, but extended forcast says otherwise at the moment...

And how exactly are you measuring "actual performance" then? No one in this thread claimed the 1/4 mile is the only metric for gauging performance (hence my comment about using a performance device for metrics like 60-130, etc). My position was that the track is more accurate and monitored than strapping a performance measuring device to ones car and claiming "track" metrics for comparative data.
The reason the C7 section is more focused on straight line data is because most of our cars are extremely heavy and do not bode as well through a road course, or other performance testing outside of straight line acceleration.
Find one person in here saying:
the drag strip is the ONLY way to truly check performance.. ...and I'll rescind my stance.

Actually his time via dragy is most likely going to be extremely accurate AND even if he's off by a tenth or two WHO CARES. He's got the car moving a lot faster than it was stock that's for dam sure!
I've driven much faster cars than my A7 (and own a Zr1 as my summer perfect weather car) but I am very pleased (that with minimal mods) this car can see anything in the 11 second time range AND go deep into the 3's for a 0-60 pass. I had the money for an RS7 but couldn't push myself to spend literally double than I would on a very well equipped A7 prestige. After only spending a few grand on the car (with very easy mods so far) I am happy that we can make the performance gap so much smaller when compared to the RS7 and with 2 less cylinders.

it's been done by a few others and generally a stage 2 car should be in the 158-160 range on pump gas - of course that's at DA of something less than 2000, I'd say at closer to 5-6k you'd be good to hit 155 - I was scheduled to do one last July but got rained out, I won't do another because the investment to participate is about $500 and if the weather cancels the event there are no refunds.

definitely agree to the weather potential of ruining a great outing. good weather permitting, it's a hefty sum, but you can run ALL day if your car is up to it and the social part of the even is great as well....can meet some good people and businesses. as for 155, was hoping for 160-165??? when i had the Jeep out there i was getting constant 160-163 in the 1/2 and had to believe that was a issue with aerodynamics and weight. lol even though the Audi is currently pushing less power and torque it does feel stronger up top and obviously more capable....the Jeep's gearing kept the ceiling at 175 (speedo wise) beyond 1/2mi whereas the Audi can top 190+ with the APR Stage II...would be interesting nonetheless.
p.s. temps when i was running the Jeep on back to back passes was 95+F

I'll probably go down. My friend/mechanic has a 1800hp gtr and now a ugr gallardo he will probably run. I want to see them.
