12.26 @111mph was fastest et of 3 runs. 1765 DA at Sacramento Raceway. It was about 88* ambient on the first run and 91* on the last run.

Overall I'm very satisfied with the results as the last time I ran in the spring with GIAC Stage 2, my best time was 13.0 @105mph at a 650 DA.

Thanks to Tony and Chris at EPL, we've come a long way. So close to 11s!

This is E85?
I was expecting to be slightly faster.
Doesn't the E85 file pushes well over 500hp crank?

It would be slightly faster in lower temps, better prep, cool down time etc. I don't know exact chp, but if you use dragtimes go calculator, fwiw, it estimates my crank hp at about 480. Our C7s are freaking heavy.

[yeuchau]

That time is similar to stock S6/7.
Did you ever try the S2 GIAC race map before?

Never ran it on race file at the track. To clarify, there was nothing wrong with GIAC, I just wanted something different.

I want to go dual pulley when the temps drop, and APR stops teasing power and starts selling it.
Maybe I'll make it to the track and see what my A6 can do after.

You should get a baseline run at the track. It makes future mods and lower times more satisfying.

As far as the dual pulleys, just get them in now. Even with an OEM file there is a nice bump in power. I haven't noticed a huge increase in iats between Stage 2 pulley and dual pulley. Pretty safe IMHO, unless you're planning on a larger than 180mm. Just 2 more weeks for APR....lol

[Tony@EPL]

Fantastic!

[Ze_Nardo6]

Those are great times for a heavy car. I'm running an almost identical setup on my S4 and based on track times and dyno numbers, we are somewhere in the ballpark of 525-550bhp if your tune is a dedicated e85 file.

Should see 11s with a better DA!

[bmre90]

Awesome, Im also running Dual pulley (JHM Though) with APR Stage 2 and APR SC pulley. Wondering when is APR going to commercialize their tune for DP? if ever- lol.
BTW, any negative impacts of E85 on engine?

No evidence of that with the 3.0 s/c engines. Been running mine for about 7 months, driving it very hard and it feels perfect.

[ntsantos]

Only downside is less mpg. But at $2 per gallon it's pretty much a wash. Just more frequent trips to the gas station.

So I've heard. I've been watching the drama from afar for the entertainment. I gotta give props to APR for their marketing strategies, arguably the best in the business. They can "produce" an awesome dyno sheet and no one questions it. Pretty amazing what they have done for themselves.

No idea, if I had to guess, close to stock S6/S7. But not really apples to apples since the S models have DSGs capable of way lower 60ft.

Is it just the transmission that holds back non-DSG cars from better 60fts?

The dsg with launch control and available tcu tunes definitely has more potential than the zf. Colby in his Q5 (zf tranny) hit 1.7x consistently which pretty damn good. Not sure if the zf will ever be able to get to 1.5x...unless someone comes out with a tcu tune for it.

[RayG]

Hasn't the ZF been around for awhile now? I guess tuners aren't seeing that much of a demand for a ZF TCU tune.

[ntsantos]

Hit Sac raceway today and got in a few runs. Best pass of the day was 12.36@112 on 101 Oct fuel. I was hoping for better but it's still in line with my previous runs.

Last track day of the year, and got to meet fellow AZ member Paul "redlinerex".

I've been extensively logging both the Race and e85 files from EPL, so I actually tried them both. I started with the e85 file running a e50 mix (using 104 Oct gasoline). Then I dumped an additional 5 gal of 104 Oct (from ERC fuels) and switched to the race file. I only had time for 2 runs on the race file, so the tune probably didn't fully adapt to the fuel change, but I was still pleased with the results.

The 2 slips on the left are on the e85 file, and the 2 on the right are on the race file. Car #121:

I was hoping to finish out the year with 11.9x, but still have a few mods to complete that should get me there first part of 2017. Thanks to team EPL for a great year and happy new year to all!

Please share your times. It would nice to see how other EPL team members are progressing. You'd be the fourth EPL tune I know of in NorCal. Good luck today.

A tip I learned from Redlinerex yesterday, crank up the AC prior to your run while in the staging lanes, then turn it off while you pull up. I watched me IATs drop over 10C prior to take off. I used to blast the heater, but the AC trick seems to work better.

Your car ran a 13.0 at 105mph on GIAC Stage 2 in a 650 DA. What was wrong with your car or your tune?

No idea. I switched to EPL within a few weeks after that run. To be fair, I never really gave the GIAC tune a chance.

Right on. I'm not trying to get in your business or anything but if you were still in the return window I would have switched too. Sometimes it can be better to get the money back in hand and let the tuner sort their stuff on their own. You could always go back later. I ran my A6 3.0T bone stock and trapped 104mph then ran it with just a DTUK box on it and dropped the ET down from 13.5 to 13.0 at 108mph so something was definitely wrong on your old setup. This was stock pulley on pump gas and +1700 DA also.

If I had to guess, my thought was that the C7 GIAC file was the same map as the old B8 file. It felt like it was never updated to the v2 version the B8 guys had. Also, if you look on the GIAC website, they don't list a stage 2 for the C7. It made me wonder what was really loaded in my car.

I could have played with the file more, but really wanted an dual pulley e85 tune so went EPL. Pretty damn happy so far.

[PKmode]

I'm surprised this isn't yielding stronger gains. I also think that a 13.0 out of the GIAC file is off. You saw my post with my car running a 12.5@111. That's plain jane APR stg2 on 93 pump with literally 80-100 lbs of gear in the trunk. I also only ran the car a total of 4x. I wouldn't be surprised if there was another mph or 10th of a sec.

Point is, I really expected a dual pulley, E85 car to be quicker. Not a slam on you, your car or EPL. It just seems off to me. I hope to see you reporting back with that elusive 11.X slip soon.

My car is still bleeding boost throughout the run and still pulls some timing. It may be due to stock cooling. Sometimes less is more, which is why your APR run did so well.

I have an APR CPS in a box right now sitting in my garage waiting to be installed. On almost all my runs, I was hitting 75*C IATs which is crazy high. I really tried to see how far I could go with stock cooling, and I may have hit the limit.

[PKmode]

I speak from experience when I say IATs can make a huge difference in a boosted motor. I chased a cooling problem with my heavily boost B5S4 for a while before I decided to do something about the IATs. Once I did, timing improved dramatically, thus making a much quicker car.

I recall Loe in the B8.5S5 ran some very quick passes with his dual pulley, e85 car before having to address the cooling but ultimately, it was an issue needing to be addressed. Let us know what solution you go with and the results. Good luck.

[ntsantos]

Finally broke in to the 11's!!

I had 2 back to back 11.9x runs. The slip below was the fastest of the two. I'll update the original mod list, but the major changes from my last runs are 194mm pulley, and APR hx. I thought the coolest thing was hitting 1.7x 60 ft on 21 inch wheels (Thanks @Fast4dr). My best 60ft previously on stock 20s was 1.80. I thought for sure the 21s would be slower.

Both 11s passes were on EPL 100oct file with e60 fuel. -400 DA

Thanks EPL team!

My guess is that the TCU controlling the clamping pressures in a DSG was easier to modify that whatever controls the torque converter in a ZF. I'm sure if it were easy, it would have definitely been done by now.

So this is a silly idea, but can you use SRM meth injection plates for NO2,( retap if needed) they would be more discreet but also provide better charge cooling. I know they cost a bit more, but your already deep into S7 territory, might as well at this point,

Pulling the blower is pretty easy, belt and 6 bolts. I pulled mine for the pulley install.

I get the concern of boost leak under the supercharger, would be hard identify and increases the potential failure points.

Is it really that straight forward? I haven't looked at it, but aren't there hard lines for coolant that need to be removed as well?

I could do a blower pull in an hour now. But having 6 N20 and 6 Fuel lines to worry about while driving 500-1000 miles per week would suck.

You guys are f*ing BONKERS! I started reading tr entire thread as I am looking at moving to an A7 - and coming from an E55 AMG I wanted to consider a tune that would give me some good torque and not leave me feeling disappointed in my move from my s/c V8.
The stage 2 epl seems like it will give me that - I don’t need to run 11’s at the track. Lol.
Thanks for the great info guys! I’m cracking up at guys who are disappointed in some of the numbers...cuz to me, I’m like SWEET, Stage 2 will have me keeping up with most cars I run across. My A7 will be a bit of a sleeper. I’m impressed with what I have read and learned of this 3.0t motor.

[Kevman9]

My brother had a E55 and he got rid of it for an S4. He’s stage 2 EPL and isn’t disappointed in the change. Obv there’s a big difference in torque between both engines, when the supercharger was actually working on the E55. The biggest difference is the trans. The E55 was slow and the S4 is way better. The A7 has the ZF trans but with the tunes coming out soon for that it will be close performance wise. The harsh reality is that back in 03-04 a 12.4 quarter mile was really fast. Now it isn’t

Stage 2 EPL single pulley, just ran a 12.65 yesterday at ~108/109. First time in the 12.6's, very happy.
