Record 0-60mph for 3.0t A6

[p3u]

I've been further dialing in my TCU with HP Tuners and produced some amazing results. It really came to life with the final revision I made. I'm very excited :)

That’s awesome. You have given us the formula for the perfect sleeper. I can’t wait to see your track times next season. Keep wrenching.

Impressive!!

[BWilson]

Very nice... nice to see a 3.0 to produce that power.

[gk1]

I’m curious can you tell me some more details on those results?
Is the 151.53 feet the distance it took to go 0-60mph?
Is the last number 2.91s the 0-60foot time?

You are correct. 151ft is the distance to achieve 60mph.

The 2.91 time is if you measure with a 1 foot roll out. Most (perhaps all) US car magazines measure 0-60 this way.

Congrats! Can’t wait to see a real time slip.

Very impressive from the 3.0T power plant.

Perfect. Thank you for the clarification.

[flyfishing]

what is a 1 foot roll out? does that mean you are in 1st gear going really slowly and moving then floor it?

It simply means they dont start timing until the vehicle has moved the first foot.

I'd love to know why US car magazines prefer this method. Personally it doesnt seem an accurate way to measure time. It should be from a standstill (3.10) IMHO.

[Jayfiniti]

Do you have a list of your mods, aside from the TCU tune?

[NickLim]

They do it because the 1st 1 foot is attributed to transmission performance

[NickLim]

Even if you had a 1000hp car if you has a shit transmission it could take u half a second to go 1 foot

[p3u]

For power adders the following:

APR stage 2+
3.56 PR
Ported blower
Porsche 997 911 75mm TB
RS7 air intake

I can see how it mimics the drag strip where there is 8-12 inches between the pre-stage lights and the actual 1/4 mile timing lights. Not so useful in 0-60mph measurement accuracy as you point out but brings quarter times and 60 foot times more in-line with the real drag strip. (Hence why I was curious if it was indicating 60foot time earlier as something didn't add up if that was the case.)

Not exactly...

This makes perfect sense. I actually found an old Car and Driver that explained this as you did. All about how drag timing equipment works.

Congrats man! I've seen your result pop up on draggy last night:)

[bobontheroad]

Anxious to experience your tune this weekend...

1 foot is all about transmission engagement.

After that the only things that matter are traction, power, weight, and aero

From 0mph to 1mph that is all transmission engagement. Shitty transmissions that too slowly apply power, or too quickly apply power will either have a very slow start or shock the drive train and skip tires moving basically no where

What is your cooling setup, and what is the sound like with your rs7 intake

Thanks man! I have one more mod that should help out a decent amount. It's my last major item and shot to get the car into 10's.

[13_C7_SC]

Were You able to do any track testing?

Pardon my noob question, but what is PR (3.56 PR)?

Also, do you have a thread on modifying the Porsche TB to work on your car?

PR is pulley ratio

They do it because the 1st 1 foot is attributed to transmission performance

The one foot roll-out is the staging light distance between shallow and deep staging at the drag strip. Stage deep and you get out earlier. Stage shallow and you get that one foot head start before the timer starts. The one foot difference by staging shallow translates into a .2 to .3 quicker ET. Great for time slips, but could cost you a close race. Dragy assumes you want optimal times and builds in the one foot roll-out.

This has zero to do with transmissions.

Huh I wonder what could cause the substantial difference in acceleration between 0-1ft and the rest of the run

A ferrari 458 will take 100ft to break from 60-0. I don't think this car is spinning the tires to 60, but let's just say it is.

100 * .19 = 19 seconds

But we know it only took 3.1 seconds

That's a pretty big difference

[NickLim]

I wonder if that has anything to do with why electric cars accelerate so well from launches

[Dirt]

They accelerate well because they have insane amounts of torque right off idle, but more importantly have traction control systems that are far superior to their gas counterparts (instantaneous because it’s an electric motor).

I guess you've never looked at the difference in your timeslips at the dragstrip when staging shallow compared to inching up 12 inches and staging deep.

Its going to make .2 to .3 seconds difference in ET. A rolling start when the timer starts makes a big difference.

BTW, there is some debate in Dragy circles whether the 0-60 timer includes the one foot roll out. We know Dragy uses it in its dragstrip mode. 0-60 is not on a dragstrip timeslip. If Dragy is using pure time for 0-60, then P3U's time is even more impressive!

There is no debate. Dragy shows what the 0-60 time with 1ft roll out separate from a standstill. See time indicated at orange arrows. I pulled 2.91 to 60 with roll out.

Very impressive. Do you have any idea how much horsepower/torque your 3.0 is making? I couldn't find it in your posts.

I've never been big on dynos, so I can only estimate. My best guess is around 450-470whp.

I made 420awhp at 11.7x@117mph, so that's about right.

Yes, I now see the roll out 0-60 down at the bottom on mine, as well. Never noticed that before. Thanks.

This means that your 3.10 is true actual time from dead stop to 60. That is fantastic!

[yeuchau]

i would assume it's probably closer to 500whp as your numbers are on par with stock RS7 (give or take a bit)

Stock RS7 is like 3.5 sec. He’s getting close to Stage 1 RS7 results.

[BWilson]

Very impressive time for 0-60. What are some of the times you other guys are producing with Stage 1 or Stage 2 with the 3.0. motor?
