- OEM interior, full weight, us spec
We were able to make our first pass at 12:08 in the afternoon with the density altitude (DA) sitting at -392.8 ft and steadily rising till around 3PM where it began falling again. We started with our local 93 octane fuel and 93 octane software and began practicing our launches. After 3 attempts we were hitting 1.7x 60' times and were passing the quarter mile mark at 11.2x seconds at 122-123 MPH. The car was very consistent producing 6 passes in a row in the 11.1 and 11.2 range, including hot lapped passes (meaning running down the strip, coming back and running again with no cool down time.)
On 93 octane with our 93 octane software our best ET the day was 11.156@123.11 with a 1.654 60 FT time and a DA of only -42.2 feet! Our best trap speed of the day was with an 11.232@125.41 MPH with a 1.772 60 FT and a DA of -58.1 feet.
Around 4 PM we switched over to 100 octane to get in a few passes. Unfortunately the daylight was dropping and the track informed us we could only run till it was dark. We only had time to run several passes on 100 octane with very little cool down time between each run. Never the less, on 100 octane our best ET and trap speed was on our second pass, only several minutes after the previous run and was 11.070@129.29 with a less than stellar 1.802 60 FT and a DA of -155.5 ft.
Overall we were very impressed with performance given this was our first attempt in the RS4. The DA on our record 93 octane passes was very close to 0 feet and we believe with a lower DA, the times could drop. Likewise, with an improved 60 foot time, we believe a 10 second pass is achievable on street tires and full weight, possibly even on 93 octane. We unfortunately do not have any data for a full high flow exhaust system and other common modifications popular to the RS4 community, but hope to see results from our customers who've upgraded further!
That brings us to the fun part!
After only a few passes on 100 octane, we decided it was time to have fun before the track closed. We jacked the car up, drained the fuel, threw in 104 octane, installed our 104 octane software, removed the passenger and back seat, installed drag slicks, and removed the factory catback exhaust for even more weight savings.
We fired up the RS4 and it was beastly! Everyone at the track crowded around to make sense of this snarling Audi in the heart of American muscle land.
We had less than an hour to get in a few passes before the track closed. The first run broke into the 10 with our top trap speed of the day at 131.67 MPH, but we knew it had more in it. On the next run we did a massive burn out and heated up the tires and were able to hit a 1.49 60 ft time, but a missed shift resulted in only a 10.7@130 pass. Eric pulled the car around, let it cool for a second and headed right back out. The next pull was his best pass of the evening, setting a 10.606@130.89 pass with a 1.500 60 FT time and a DA of -528.2 as the sun was dropping. We were so close to 10.5's but there wasn't enough time to get in many more passes with any decent cool down time between. We were able to run 3 more passes several minutes apart and cut 10.6's on each one with trap speeds ranging from 130-131 MPH.

[@Cyber_Nomad01]

Sounds so much better without the OEM Catback.

[@jfoster33702]

Time to start putting these blowers on sale - only so many RS4s out there ;) (RS4 owner who wants a less expensive APR blower here)

[@eastoakland-S65feen]

I know im a little late but do you still have the rs4??

[@bharvey2010]

Seriously Wow. Love the level of performance for such a "refined" car.

[@grantmotox123]

Glowing exhaust at 3:50 looks awesome !!

[@anadiri964]

THE MANIFOLDS ARE GLOWING!!!!!!

[@reallife4598]

Now looking at this makes me want to keep my b8 s4

[@TheTexican05]

Sounds just like a high revving 7500rpm small block when they pull the catback off. Love this vid! Great work from the OCD folks at APR. :-p

[@Mack1906Mack]

After 2:03 that thing sounds like a grizzly bear ass rapping a yetti!

[@rturunc]

APR only makes the best...Love it...

[@tadam25]

It sounds absolutely incredible

[@sounddd]

WOwwww sounds so good, and damn that was awesome. anyone else see the flamethrower

[@kevingadoury9381]

this footage is absolutely amazing !

[@HEKTIC458]

Thats mental, sounds so nice

[@exothermal.sprocket]

Make sure to give that stick a good 2 seconds of rattle and slop after passing the quarter.

[@ChrisOstberg]

Nice runs. But man, please tell the driver NOT TO DROP THE ENGINE TO IDLE AFTER GOING THROUGH THE TRAPS!!!! You bring your coolant and oil flow to its minimum immediately after a long pull. It's a bad habit, increases wear, and can even kill an engine. Leaving it in gear keeps coolant flow and oil flow going...

[@Xtasy604]

Actually that's where you are wrong, leaving it in gear brings cold air into the engine which is even deadlier, imagine your pistons scorching hot from combustion then drawing in ice cold air. That will kill engine. A modern engine generates enough oil pressure and coolant flow in an engine at idle to not put harm on an engine

[@ChrisOstberg]

Xtasy604 - That's not how it works. With the throttle closed, not much air is getting in and the cooling effect is minimal. After a quarter mile run, the intake air temps are nowhere near "ice cold". Modern engines do generally have enough oil and coolant flow at idle, but they are validated at stock power levels. This car is making 50% more power than stock, which means you can't assume it's enough.

[@Xtasy604]

The cooling effect is quite drastic.....on my own car, a Turbo S2000 with a GTX35 turbo, making 450whp daily and 650whp for high boost, the exhaust gas temperature is upwards of 1400deg fahrenheit. If i lift off the gas, the egt goes down quickly.

[@ChrisOstberg]

Xtasy604 - That's mainly because you stop putting air and fuel into the combustion chamber, not the cooling from the intake air. Have you ever taken thermodynamics? That's like saying your oven cools off inside when you turn it off. Well, yeah...you've taken away the heat source.

[@Xtasy604]

Quite frankly, i have. Eitherway, letting the engine, engine break causes more changes in temperatures than letting the car idle in neutral. Even at 50% more power than stock levels. The demand of the oil film on the bearings and water pump do not substantially increase. Specially at idle.

[@aukevin13]

Great video. Love that car and set up. Great driving too.

[@brandonowings4268]

Oh my God the sound... Yep next project now

[@exposingdemocrats8370]

Wow 10 second Audi. Imagine the torque from that Supercharged V8

[@BigRyGuy04]

DAMN! Beast-mode!

[@rexluther244]

Just became APR's newest fanboy

[@watts6087]

What a beast i want this kit on mine :)

[@KP-wi3vc]

Cant wait to see this on a RS5 with additional bolt ons.

[@marcelofiguera7263]

Why? The B7 RS4 is an icon a thing a RS5 will never be.

[@phillipjones4743]

nicely done

[@AUDIABiQUATTRO]

Awesome 👌😍

[@The_gabagool247]

So badass!

[@LordToxygene]

The suspensions seems a little soft. I wonder if the times could have been lowered with a stiffer setup?

[@APRtube]

Lawrence Szabo , the suspension was stock, so we believe with a better setup, it could improve acceleration times!

[@raph0412]

The car is just sick. This video is just sick. How much hp does this have? 500-600hp?

[@APRtube]

raph0412 the car produces between 500-600 All wheel horsepower (not crank) depending on octane ranging between 91, 93, 100 and 104.

[@iamdatdude1619]

+raph0412 I FEEL THE SAME WAY YOU FEEL !!!!!

[@Jolinator]

+APR, LLC. what ever happend to the rs5 supercharger kit you guys said was coming out some years ago?

[@kevingadoury9381]

As an owner of a supercharged 4.2 myself I love this amazing video for sure. But one thing keeps bogging me. How can you have the perfect car, the perfect setup, the perfect temp and a reaction time of 1.5 sec?!!

[@exposingdemocrats8370]

Rule of thumb, just shift 500rpm early. You’ll see the difference

[@supersportjames9452]

Unless you’re racing someone in the other lane reaction times don’t matter. They don’t do anything for your et either. I can cut a .060 rt if I need to but if I’m testing and tuning I leave when I’m comfortable

[@LegacyIvyTerascale]

1:53

[@VulkanmadAD]

Imagine that on an RS5 and launch control!

[@Ravensbrueck]

Hell. Yes.

[@Cabtrack_TTRS]

Waouwwww good job guys

[@gw819]

I could watch this all day... amazing. When did you install the NASCAR engine? lol

[@georgem.kracke8785]

SHUT UP AND TAKE MY MONEY!!!!

[@XYZGolf]

I love it

[@fastestaudiwagon]

Nice runs with even better results. Is that car utilizing some type of 2 step, or is it launch control? Please forgive me for knowing nothing about the features that are incorporated into an rs4

[@lsevent]

No launch control, just good old fashion driving and JHM clutch doing it's thing.

[@APRtube]

fastestaudiwagon We are using APR calibrated Launch Control.

[@lsevent]

APR, LLC. Are y'all going to start providing launch control in your other tunes as well? Or is this a one off thing?

[@APRtube]

Google+ Sucks We are working on it for several platforms.

[@princepersia1]

Is the cat-back removal for extra power or just sound and weight reduction?

[@pcracinggames]

1:41 that's more like it

[@Jmschnider]

Are you flatfoot shifting? Or hitting the rev limiter every time lol

[@eapaaa]

amazing sound difference between 93 and 104 octane! did you guys had to change any internals?

[@APRtube]

eapaaa , the difference between 93 and 104 setups had to do with exhausts from a sound stand point. Check the video notes for more details. The engine internals are still all stock.

[@eapaaa]

APR, LLC. Thanks for the details, sorry missed the info section.Any ideas of over all cost for the above setup? and do you've any dealers in Dubai-UAE ?

[@APRtube]

eapaaa check out our website at goapr dot com and use the dealer tab at the top of the screen. From there, you can type in your location and see our local dealers in the area. : ) This kit is not released yet, but should be in the near future.

[@justme3350]

Is that a 10 second car you owe me?

[@GeeGee2264]

Is that a no-lift shift feature he's using? Lots of time on the rev-limiter in the beginning?

[@joshuamedina8920]

Needs some Mikey Thompsons !!!

[@jameswilson8820]

Way cool😎

[@360sully360]

dont you just wish your daddy owned APR and did all this to your own rs4. The price of this modification is more than my rs4 is worth. Time to put some money on that euro lottery XD

[@Primer9]

the microphone quality made the vid

[@jdportwerks6795]

Wicked

[@pembroke1716]

how much would this 93 octane setup cost (supercharger, pumps, exhaust, etc..)

[@donatasdo1063]

wow !!!!! insane car , insane work !! TVS1740 cann use for 4.2 liter non fsi 40v engine ?? what is the diference betwen these S8 D2 40v 265kw engine and 4.2 fsi engine, apart direct fuel injection ?? I think this supercharger cann be used for non fsi too yes ??

[@taifly451]

how does removing the catback exhuast make it that loud? at the end where u guys were doing 10sec what did u do to make the car so loud?

[@kingkonginthetrunk]

Open downpipe....no mufflers, cats, anything....

[@B7_S4_Turbo]

tai fly lmao

[@Photosbydrew]

love my stage 2+ apr gti. when will this kit be released?

[@jademassaro7595]

just made another customer :)

[@AcEzABoy]

I want my RS4 to sound like the one that runs 10.606

[@TylerDickey1]

Sweet baby jesus. edit: Does the track not require a cage?

[@firesquare16]

Depending on the particular race track and their MPH or ET or both.

[@APRtube]

We rented the track.

[@tombarsky7321]

too bad APR doesn't offer driver mods..

[@ryanmakurat3769]

Am I reading the reaction time correctly?

[@viziuz64]

how much is the setting for an audi RS5?

[@APRtube]

Aldo Benavides , we don't have pricing for the RS5 unit quite yet.

[@AUDIABiQUATTRO]

Why does it smoke so much?

[@MikeB-ng3ol]

Does APR not sell anything other than software now?

[@JGTRADEZ]

APR can i put this on my rs4 i live in California

[@WaydUncaged]

Dudes gotta stop hitting the rev limiter at every shift. It’s almost every time he upshifts.

[@neilkilner9526]

Is this charger out for the rs4 b7 whats the cost please

[@Super73VW]

almost $18k www.ecstuning.com/Audi-B7_RS4--V8/Engine/Supercharger/ES2746466/

[@flexl311]

is TVS1740 better than a whipple supercharger (PES) ?

[@jmey107]

The PES supercharger does not even come close to the apr one, especially in terms of reliability and warranty.

[@APRtube]

Yes, this uses a TVS roots style charger while whipple chargers use an "always compressing" screw type system.

[@megabunnydeath]

Do they still make these?

[@PASKI502]

nc bro nc car :)

[@vadymbrykalov8733]

whats the 0-60? really curios to know!

[@TheTexican05]

0-60 in 3.0 seconds is the breakdown with that 1/8th mile time (0-100 in 7.2). Just wicked! Love my Opelika peeps at APR.

[@dolphinb6s420]

I want the run at 2:10 to be my ringtone.. someone teach me how

[@eapaaa]

download the video via freeyoutubedownloader app or similar than that app can convert the video to m4a or mp3, than you need yo cut the section you need ;)

[@dolphinb6s420]

THANKS!

[@vitomelchionno6225]

Stock engine?

[@johnnyjohnz1992]

how much power with just 93 then

[@PIchillin456]

626 hp and 529 lb. ft. of torque with 93 octane.

[@Willtext]

What’s a stock one of these do 1/4 mile in?

[@B7_S4_Turbo]

12.8

[@Defkhan5059]

power shift ;D

[@soundseeker63]

Goes well but sounds a bit dull with that regular exhaust. Sounds more like the newer 4.0TFSI than the better sounding N/A 4.2. BTW why would you shift into neutral at over 120mph!? Surely thats dangerous and can't be much good for the engine?

[@B7_S4_Turbo]

soundseeker63 it's fine

[@ediliomartinez89]

RS4 awesome

[@shpatbardiqi6459]

0-100?

[@luisortizvazquez]

Sounds mean.

[@HaloHamstur]

Nice but not for 17 grand.

[@exposingdemocrats8370]

Faster than any 911 besides the turbo s. That’s 200k compared to this 15-17k blower plus 20-30k for RS4 used. Then another 20k in overall time In ownership due to maintenance.

[@iceman49bg]

do wannnnnt

[@mkoho]

он вобще так сильно не прав, когда в нейтральном положении тормозит с более чем 200 км\ч

[@grahamek86]

If only that car had someone that could drive a manual transmission, I reckon there's 0.1 in int.

[@gamofetish]

finally
