S7 with RS7 Turbo Kit, dyno, launch, race

**SoloMotorsports** · 04-04-2016 02:12 PM

We just installed some RS7 turbos on this S7 with our custom software and got her out for some testing. What a difference!

**eyeloveteeth** · 04-04-2016 02:13 PM

what type of custom hardware?

**LINDW4LL** · 04-04-2016 02:46 PM

Amazes me that some people have the brains to earn/purchase a Ferrari yet are still dumb enough to smoke cigarettes. IN the F12, too.

That short shift then creates a huge bog as the engine now has to crawl back into the power band. This is surely making the car a lot slower. Then you show the S7 lining up with a Ferrari as if to indicate they are going to race but the Ferrari driver just continues to smoke his cigarette instead of actually race. Pretty lame.

I have to agree with both of these... What is the point of this video?

**S4M3** · 04-04-2016 02:52 PM

The guy in the F12 just doesn't care.... F12 is his daily driver , and he loves to smoke :)

I agree. Need more information on this. What else did the car have besides new turbos. We're downpipes upgraded. What about coolant system. Intake? What were the dyno numbers before and after. Wasn't sure too many folks could custom tune these.

why not just get a RS7?

**tonymission** · 04-04-2016 05:22 PM

I'll be going by to see the SMS guys soon. These dudes are legit locally and have done some great custom tunes.,,
Can't really comment on the video and the cigs.. I vape lol

Not much to go off of on the video, couldn't tell if the f12 even launched. Should have let him get the jump and show the S7 win (assuming it's faster).

What were the dyno results before/after?

**SoloMotorsports** · 04-05-2016 07:23 AM

The F12 is actually much faster.... the owner is a really good customer of ours and is a car nut. He races all his cars and gives no F@cks, we cut out his win to mess with him... Kindly refrain from criticizing him in this thread as he is a good personal friend of mine and took our joke like a champ. We all know smoking is bad m'kay. See the vid below of the S7 getting tree'd pretty hard off the light.

The S7 has Catless Downpipes, RS7 Turbos, Stock cooling, Stock inlets and airbox on 93 octane. We just ordered an rs7 airbox/inlets for it. The S7 was getting pretty high intake air temps at higher boost levels so I turned it back down.
The RS7 hardware is all stock except a cat back exhaust. RS7 is under the knife right now getting catless dp's and meth injection installed; stay tuned for updates on that one.

so here's the $1,000,000 question. Do you think our Tranny can take the extra power (S7), or should it be rebuilt.

**Clipse3GT** · 04-05-2016 08:45 AM

Will you dyno the s7 with the RS7 intake and inlets and post the comparison?

**TurtleHaste** · 04-05-2016 08:52 AM

I think this tranny is capable of more. Until one of the clutch packs slips under load, I don't know if we'll have a number. I do know you want a TCU tune for the higher clamping pressures but aside from that, the limit isn't known. Even if a single DSG starts slipping, it doesn't necessarily mean it was due to power limits. Every clutch given enough wear, will eventually begin to slip. I know some aftermarket options are coming our way.

Unfortunately the answer is that only time will tell. Audi went with the zf tranny for a reason with the rs7. Eventually I'm sure the clutches will need to be upgraded on the s7.... not unlike any other audi on which we do turbo upgrades. As of now the S7 tranny is holding like a champ.

Yes we will.

**Clipse3GT** · 04-05-2016 08:56 AM

The TCU in every dual clutch car is designed to slip some to prevent driveline damage as well as smooth shifts. So the more slip more clutch wear thus a TCU tune should increase clamp pressure. Based on torque limit setting, pressure, trans oil temp the TCU adjusts the slip or decreases slip.

**TurtleHaste** · 04-05-2016 09:07 AM

Just FYI
Mustang dyno after about 30 minute heatsoak

We weren't able to disable traction control without getting errors. Also due to strapping the car down, the ride height was changed and suspension error codes came up on the DIC. Disconnection of the ABS module solved this but by then we had already done 3 half-assed dyno pulls which got things hot. Then there was the above pull.

I haven't seen any clutch slippage on any of the tunes. I think this tranny can take a beating for sure.

I'll rephrase... Torque intervention limits.

What is the dyno chart comparing?

I'll refrain from going too much into detail here. But consider that by the end of this session we had done about 7 runs, with consistently lower output levels with each successive run, the heat (in fact any heat) will affect how much any cooler will be able to bring temps down due to what intake temps you're starting with (prior to the cooler). Heat soak (always) happens, just how much depends on several variables and I'd rather not derail this thread. The point of my dyno was for reference of this S7 as they tune and to highlight at current output the torque limits of the DSG aren't an issue.

Am I right in thinking that the heat soak seen on the dyno is a lot worse than you've seen in the real world? Cooling/airflow in those dyno environments is usually quite bad compared to actually driving on the street.

**TurtleHaste** · 04-05-2016 09:28 AM

Oh yea for sure. I didn't have a lot of airflow to cool my setup. Best to have a nice 75 mph simulated airflow and not to be idling somewhere that everything in the bay becomes hot after 30 minutes and the sitting and chilling (and idling) between every run things get very hot. Not ideal. Nothing beats truly driving on a freeway. Also indoor temps are usually quite different than those on a freeway. Can't do much about that though.

How do you like the AMS cooler setup ? Any logs before and after ?

I love it. it's definitely the best turbo cooling you can buy right now, although a pretty penny. There was a lot of thought that went into it. I bought for peace of mind and consistency. No logs, but I would have loved to do that. I can say that generally the cooling block (section where the turbo outlets feed compressed air into) feels extremely cool to the touch (almost refrigerated in comparison to the outlets).

If you have a enough airflow, I believe it can't really be beat at the moment.

I hope this will work ..

**Chris Morales** · 04-05-2016 10:44 AM

Is that a meth kit on an S7?

**S4M3** · 04-05-2016 10:56 AM

Meth Kit on the RS7. Here are the mods Miltek 3 in downpipes with electric cut outs, Meth Kit, Custom tuning. We will post dyno numbers soon, but most likely we are going to install the same meth setup on the S7 with RS7 turbos.

**S4M3** · 04-05-2016 11:27 AM

I did it was stock motor with rods, 2.8 heads, RS4 manifold on E85 with stock Rs6 turbos and trapped around 134 mph. :)

**tonymission** · 04-05-2016 12:23 PM

That's my guy Dominic's RS7... he's going to pick it up tomorrow. I might try to swing through if I can get away from work for a bit. It's not super close to my office.
He's pushing me to go bigger. lol

**Chris Morales** · 04-05-2016 12:30 PM

Looks like the meth injector bungs are drilled into the turbo outlets. Is that right? And this is pre-intercooler. I'm really interested in learning how this setup performs and what tune it is used with.

Yes, this is the only place you can install the bungs. Intake air temp sensor is located right there too :0

Can you measure inlet / outlet for id / od for RS7 vs S7 how they compare to each other?

The id on the rs7 inlets is 6mm larger than the s7.

Hey, a few requests I'm sure would make everyone happy. (If you have time, and of course this is a favor)
Could you take a couple side-by side shots of the RS7 inlets, and compare them to the outgoing S6/7 inlets? Maybe measure the diameter of both sides of each set for people to see the differences?
Finally, since you'll have the turbo cold-sides exposed, maybe you could measure the actual turbo inlets of S6/7 and also the RS6/7 to show the differences (if any), and see if the stepping inside the inlet has any differences also?

This may be a bit much and I completely understand if you just want to get this thing rolling. Just not a large window of time before things will be a pain to check after the fact.

+1. Would really appreciate knowing this, also.

Interesting thread. Wish we had someone like SoloMotorSports here...

**SoloMotorsports** · 04-06-2016 09:09 AM

The results are in! No peak gains were made but we picked up about 40wtq through the middle of the curve after installing the rs7 inlets. The top end is still suffering from high iats.
Keep in mind I made a few changes to the file to accomplish this. Just installing the inlets without any tuning modification yielded about 15wtq gains in about the same area.
I've also included reference pics between the stock and rs7 inlets. The s7 inlets fit inside the rs7 inlets which have a 6mm larger ID.
The airbox outlet and filter are also larger.

**Dguth** · 04-06-2016 09:31 AM

In my mind if you go this route, it proves you really should do the coolant upgrade to get optimal gains. But then again, you also need a tuner willing to tune it properly in order to take advantage of the new hardware.
