That’s fucking ridiculous
Help me understand this so I’m not losing my mind
On APR’s dyno, which granted is a hub dyno which reads a bit higher than most…and is in a room with amazing air refresh and fans etc which helps…so let’s just pretend it reads maybe a steady 8% higher than most dynos
APR Tuned S7 is making 569 hub TQ peak (and 500+ from 2250-5250 RPM) ???
Even if we discount that by 8%, it’s 525 WTQ and makes 460 WTQ from 2250 to 5250?
Holy shitballs
p.s. you posted Torque twice. I guess we could figure out HP.
RPM HUB TQ HUB HP
4,000 550 419
4,500 535 458
5,000 505 481
5,500 470 492
6,000 425 486
6,200 410 484
So just about 492 Hub HP or with that 8% to approximate a tough mustang dyno around 450 WHP). I guess that’s the race gas 100 octane file??? (no labels makes this tough)
That’s pretty mental. Guess those turbos are smalllish for the motor. Interesting how it falls off and peaks at 5500 RPM. Feels like a K03 turbo’d B5 S4, but ratcheted up by about 50%.
Here’s pump gas if that’s the first chart
545 hub tq peak (~500 WTQ on typical tough dyno)
475 hub hp peak (~ 440 WHP on typical tough dyno)
Interestingly enough I average 403 WHP and there is a mustang dyno graph, stock, here, that showed 399 whp. Pretty close!
I posted the 93 and 100 graphs.
It’s cut off on my screen.
Copy the link into a browser and you’ll see the full image.
93 is the top and 100 is the bottom graph. They are both labeled on the far right of the image (which is cut off on this forum)
Good stuff Arin!! Thanks for posting. This is making my decision even easier… 
Ah its not cut off… My screen was just too small
WOW!!! Very cool Arin! I wonder what heavy hitting racegas could do, maybe with some better tires, your new intercooler and exhaust you might touch 10s on stock turbos!! If not it will be low 11s, that’s great! Congrats, congrats, congrats.
I think seeing what it does on stock tires is far more relevant than with drag radials or purpose built wheel/tire setup. It’s a 193" long boat.
Either you’re at the dragstrip for
a) benchmarking performance and performance gains
b) to run the absolute fastest time
c) fun
If you’re there for a), which APR was, then putting drag radials or race gas on/in the car make about as much sense as stripping the interior out of the $80,000 luxury car would. If you’re there for b , you should really reconsider the selection of the car for one, but if you just want to run the fastest S7 time, sure go nuts, but it doesn’t make sense for APR. if you’re there for c, again, do what you like, but it doesn’t really dictate what APR employees should be doing with a shop car.
This race gas infatuation is so odd to me. It would be like finding out what your car can do with a tune…then driving it around on the stock file all day. But telling everyone what it ‘could’ do if you got it tuned again.
To be quick:
I just don’t get it. I’m pretty much on my own on that, I know. I just like telling everyone they should think like me.
I didn’t say I was frustrated…I said I don’t get the infatuation. You read too quickly!
Where’s your yellow car at? What about your silver car?
Before working for APR I used race gas a couple times on my GTI. We had a local station so I would fill up on the weekends and have a bit of fun. It was just more power that lasted for a couple hundred miles. You better believe I looked for every and anything to race while I had a tank filled up. ; )
Other than that, I’d mainly use race gas if I tracked a car. All the tracks I’ve visited with grand-am and world challenge have race gas on site. I’d fill up with the race juice all day while I’m out there.
For the drag strip, I’d fill up with race gas for fun to get good time.
Haha oh ok.
Well, the silver car is planning to be picked up when my tour is closest to Seattle. I’m flying from Albuquerque the 18th of march as of now. Things with his RS4 kit took precedence. I’m doing the 605.2s Jason is tuning with meth and without, and a 104 tune most likely. Then I will drive it to Kennewick where I have a few shows and then the next two weeks. Then my sister flys out to hang out for a week and will drive the car home with GB (assuming you met him at the shop). Yellow car is most likely may, I would settle for June. I plan on doing the USP drivetrain this next winter, depending what the silver car sells for. Until then both cars will just be trap seeking vehicals haha.
YES!!! A true enthousiast. So you hear what I’m sayin 
S6/7/8 on E85 would be cool…and it’s not race gas. It’s better
stock turbos you probably could do it. When the stage 3 comes out I bet they would have to Jbweld in some injectors to have enough fuel.
That is assuming the stock pumps and lines can handle the sauce. Although it seems the stock pumps and lines can handle a lot of power in most Audi products.
Im guessing you’d have to do something about the pumps on stock turbos but other than that it should be doable.
I’m not worried about fueling right now. If upgrades are needed, we have solutions.
the newer direct injection cars have serious injectors and pumps.
Oh sweet! Good to hear! You think an E85 tune is possible on stock pumps B8 s4 stage 2? What about stage 3?
E85 is another story
