I'm still at a loss on how you can pull off a 4.2 in the I4 and I cannot get under 6.0 with the V6.

JACFAB is modified and tuned. There are so many variables going into this ... Temperatures elevation humidity driver wheel spin also remember there is a diff between the auto and manual that the auto timer starts the second your RPM move so you cannot launch properly.

You can also go downhill. and get a better time LOL so so so many variables.

It gets better. Since this run he has run a 4.0. His car is modded, but nothing crazy. He really has that turbo dialed in. Amazing results!

I'm hitting 5.1 to 4.9 on a consistent basis the A8's are weird on when they start the timer some do it above idle some don't.

Very true, lots of variables... I get my fastest times in the morning with the temp is 50-60 degrees, in the afternoon when its in the 90s-100s it can typically be .3-.5 slower,

Ever since the discovery of the timer reset trick, I've been getting more accurate times on the dash timer, but it's gotta be right on when you reset... do it too late and the timer doesn't even start, do it too early, timer still starts before you start moving. perfecting the reset trick, I'm shaving .2-.3 off the dash timers inherit false readings. Granted still not perfect, My 4.0 dash timer run is something like 3.91 in HP tuners logs, but using the reset trick its pretty close.

Also gotta remember, I have my race wheels on, 17x4.5" skinnies in the front and 18x9.5 w/ sticky tires in the rear. These wheels are appx 75lbs lighter than the 20" wheels, and the old theory is that for every lb of rotational mass removed, it's like taking 3 lbs off, so in theory, that's like 225lbs removed off the car. Also, have done an LSD diff swap, so that really helped with traction.

Obviously tuned, running 24-26 peak boost, and normally in the 22-24 range when off peak at WOT. I've been doing nothing but street tuning this thing for something like 2 months. I make 3-4 pulls in the morning, and 3-4 on the way home every day, while making changes in the tune before each trip. I've got the transmission shifting stupid fast...

It's not just a stock 4 banger

I just wanted to point out guys although we are comparing weather and elevation, there are also alot of mechanic factors that will make a big difference in the 0-60. For example, our cars are geared with 2.77's in the rear axel or basically they are geared for higher speeds so they may lag in the 0-60 but they will not run out of breath below 150 .. I don't know how the turbo 4's are geared in the rear axel but they seem to have alot more torque down low than the V6 does and if they have taller gears, the power difference stock isn't really great enough to offset those differences for the V6. The other thing is WHEEL packages and there's so many of them that come from the factory. The 22" wheels will probably help your 0-60 more than the 18" (larger diameter = more acceleration).

I tried to see if it will stop the timer if you stop accelerating, like for example if it starts when i start accelerating I stopped before i reached 62 to see if it will stop and give me a lower number. It didn't, the timer stayed at 0. The timer will only give you the number once you reached it. Maybe its a glitch, I don't know. But I certainly don't believe it myself and much like how i did on that original post I'm not going to act like my car is any more special than any other one, I just wanted to share the crazy number i got.

Holy sh*t, Thats what SS's are running... what a phenomenon!

I don't agree with the larger wheel = more acceleration thing at all.

1) larger wheels are heavier = more rotational mass = slower

2) IF the tire sizes between a larger wheel and smaller wheel, are different, that will also fudge the gear ratio (taller tire = higher gear ratio, shorter tire = lower gear ratio)

For instance, I currently am running some 18" Corvette wheels in the rear, and a shorter tire. It basically fudges my gear ratio to somewhere around a 3.64 ("lower gear", numerically higher) up from a 3.27 stock. All my "race" wheels together, weigh about 75 lbs lighter than my stock 20" wheels. If I put my stock wheels back on, the 0-60 is about .5 sec slower. Lightest, smallest wheels and tires possible = better acceleration than big heavy wheels and tires.



Btw... Just finished my water/meth injection install with a retune... Still with my race wheels on obviously. I'll put the 20"s back on in October.

3.8??? Holy Jesus. My personal best is 6.4 at altitude. Stupid altitude.

Are you tuned for the tire size? If not those are not true 0-60 times. Not calling anyone out, just curious.

Which ECM does the 2.0t use ? are you using hp tuners for your tuning ?

[Evil-Bee-NH]

We only have HPTuners as a real viable option some have used EFILive options. Jason's car is heavily modified yes we have taller gears in the I4. He's also done the M6 3.6L LGX eLSD swap into his auto which apparently bolt's right in. He's pretty much run at the forefront of the tuning development I mean the ZZP Shop Car hit high 11s with a full tune and bolt-on package stock turbo.

It's an E80 ECM w/ T87 TCM, yes I am using HP tuners

Yes, I have spent hours just trying to get the tire size right so the speedometer is correct and the transmission shifts right. It seems even from the factory they use the tire size as a fudge factor, because even stock, the stock tire size in the tune was wrong. So even though my race tires are 25.4" tall, I couldn't just input that number. I just to fudge it to whatever it ended up being to get the speedo right. The speedo actually reads 1mph slow compared to a GPS, I figured close enough, and better than fast.

I'm at 1400 feet, but density altitude at the track is usually 2400+

I wouldn't even say it's heavily modified LOL... I'm still running the stock airbox and tube, just a K&N drop in air filter. stock intercooler, stock turbo. *we have lower gears (numerically higher)* 3.27 vs the a8 v6 2.77 right?), but the manual v6 has 3.27 also.... I think only the SS comes with the eLSD? LTG and LGX have a conventional LSD. My rear end came out of a manual trans 2.0 car (LSD), my auto trans car did not have it (LSD). Pretty sure the LGX rear end and axles would have worked also, should be the same, but I could not find a manual transmission LGX car in a junk yard anywhere.

V6 A8 1LT all stock OAT 55 degrees ~200' ASL. It's the exception, though, I usually get about 5.2.

How you get such a low 0-60 time? My car is an auto
And I still get 6.1 sec or so.
