Audi S3 8V with APR DTR6054 Turbo upgrade and EQT Custom Tune

We take full advantage of APR's DTR6054 Turbo upgrade on this Audi S3 8V with some custom dyno tuning from EQT. The turbo is definitely capable and it shows with the right mods and software it will make the power. The upgraded map sensors, and HPFP upgrade with custom tuning made the difference on this one.

Audi S3 so much cheaper virtual cockpit and all are DSG

@@moereefer S3 is not cheaper lol but I way prefer the S3, more classy but it's personal preference.

@@bslothed3211 i mean used for some reason there price drops big time. there was a like 4 videos on the topic of S3 bigger brakes virtual cockpit and cool exterior notion lighting. Dude in Blue made a video. plus your actual getting Audi RS3 same chassis and good aftermarket support

[@hellaflushhonda]

I’ve got a 7.5 Golf R and EQT is HUGE in our community. have always seen people mixing turbos with the EQT custom software but no one’s done better (that I know of) ( and as far as a drop in bolt in turbo) then the EQT Vortex XL pared with their software. EQT is an awesome company!

[@05pharmd]

500hp R, ultimate DD IMHO. That hatch practicality is hard to beat.

[@volkssturm9694]

S3 all day over the others.. I have basically the same car... FL 2018 S3, Im just about to go to stage 2 with 034 motorsports and calling it a day. This car is my daily driver and Im aiming for the perfect reliable /quick car without pushing the limits at all of this engine. I have my CTS direct fit intercooler (new version ) and CTS downpipe already. My S3 is already pretty quick, runs low 12s in the quarter with just stage 1 ECU/TCU from 034. This platform is amazing, just stay on maintenance and these cars will last a long long time.

[@bslothed3211]

Ay nice on the 1/4 time. I'm about to pickup a 2016 S3 next week. Already test drove it when it was bone stock and it hauled ass, I could just imagine what a simple stage 1 would feel like

[@Adrian-ej5uu]

S3 is growing on me as well looks so damn good

[@moereefer]

I think it’s the Best Buy right now all Audi S3 look like RS3. And all come with dsg trans. There are VW Golf R for sale but it’s crazy expensive unless you get a manual which half the PRICE. CRAZY

[@CliffB5A4]

I'm totally biased on the Audi's, they're just so good looking. 😍

[@moereefer]

Plus all dsg more options and virtual cockpit

[@volkssturm9694]

100% audi 4 life here. Love this car, have basically the same S3 in mythos black metallic. Im going stage 2 and stopping there because I want a really reliable daily driver. Im going with 034 for my tuning because its probably the safest tune out there while still having great power output.

[@CliffB5A4]

@@moereefer I prefer my B5 with three pedals lol.

[@CliffB5A4]

@@volkssturm9694 doing the same with my B5 man, I've put a garrett gt2871r on it and only want a conservative tune because I want it to last because the car is like new. From what I've read on the various audi forums 034 is the best tune out there.

[@OPFOR109]

I love hatchbacks and fastbacks.

[@scotiacoastyachts1]

Audi S3 for the interior, R for the hatch, shame we don't get the hatch S3.

[@KevinsgolfR]

Me and Cory gonna go hard this summer lol

[@boostinboyz4639]

Golf r is mt favorite out of the two. Great video!

[@JordieG8]

I’m bias but the S3 with the carbon package is super sexy. I agree 💯 that the Golf R is more practical, but there is something about the hot hatch boy racer look that I’m over after 10 years with a GR STi. Mine is an 18 S3 with and IE intercooler, intake GT2260s, and an CTS MPI kit. For a very very loose comparison is made 395WHP / Mustang on E30. It made peak torque of 395 at 2900. The turbo is pretty much on the upper end of its flow as it’s getting close to the 185K RPM limit. My engine bay looks very simple to this one. Lol

[@DSW_Racing]

You're running MPI with the 2260?? I am just on upgraded HPFP only and run 400 whp on e40 with IE stage 3 tune.

[@JordieG8]

@@DSW_Racing Yes. You can get away with E40 on the HPFP just fine, but the injection window is pretty tight and there isn’t much headroom. I also like the idea of getting some fuel to the backside of the intake valves to help with carbon deposits. Also, for track days I like to run a bit more ethanol to help with the heat. I’m actually going to revert back to a stock HPFP with the MPI now installed.

[@bryanjenkins7810]

Thanks! S3, four doors please.

[@COMotorsports]

Appreciate it, I'm a 2 dr guy. 2dr Golf R's... wish we still got them.

Golf r coming in to the shops soon im excited

[@pudermcgavin4462]

I'm a hb/wagon persona myself. Also I'm sure you heard HPA is buying a bunch of Chinese market 2,5 vr6 motors to build up and sell!

[@Kevin-hm2di]

if we could get the hatchback 8V (aside from the etron and 2.0 tdi) id be so happy. ive thought about looking for a TDI hatch that needs an engine/trans and swapping a 888.4 or maybe even the new HPA VR6, but money is a thing

[@ryancherry4076]

S3 over R i like a sunroof lol

[@jameshaulenbeek5931]

When it comes to the VAG cars, I definitely prefer the hatches and wagons. I'd love a Golf R, but a RS6 Avant is one of my halo cars. However, old Hondas I prefer the sedans - my 91 still being one of my favorite body styles. Angular, but rounded just enough to not look overly boxy, wonderful proportions...

[@jameshaulenbeek5931]

*91 civic

[@brianisbell9743]

@COmotorsports If your planning to eventually go bigger turbo, full e85, port injection and all supporting mods is there any big benefits to starting with an s3 over an a3? I.e. are there major improvements in the shortblock, or in the transmission, drivetrain?

[@SleeperS3]

in the market for a 2018-19 A3 love the sleepers

[@COMotorsports]

Yeah the AWD a3 is a good bang for the buck.

[@LoXHumaN]

Yeah, people always get surprised when I race them and they ask what kind of Audi it is. It’s just an A3 with now an is38

[@bradcraig8841]

Great video like always!

[@JDM4TW]

What numbers you think are capable on e85

[@TruEGTI]

Hey boys, another great MQB video. Real quick though I couldn't catch the part about the down pipe. Did you say it's running stock down pipe right now with those numbers? Keep up the amazing job fellas! Never give up!

[@carlow_fc1]

No, he said that the upgraded turbo may use the stock downpipe, the car currently has a CTS downpipe. Hope that clears your question.

[@TruEGTI]

@@carlow_fc1 funny as soon as you mentioned CTS i remember him saying that lol. Yo they should have done runs on the stock down pipe. I bet at 30 psi they'd blow the innereds right out. Haha funny as hell

I'd trade it in for a mk7r. Lol

[@IGY6MJ]

Curious why not E30 or E85? Seems like a lot more left, especially if crap 91 is what’s available locally. Nice build 🤘🏻🔥

Because we don't have ethanol here at the pump.

hi guys can you tell me when i look at dyno sheet from integarted engenering on golf R mk6 st2g pro witn intake sayain 380 HP and 410 lb-ps is it a crank or at wheel ? And for the S3 409 hp at wheel how much at crank ? About just to have an idea. People alway ask me number on my car !

[@pro50joe]

Damn 342/337 was on APR software and stock downpipe? That’s surprisingly low conspired to what APR advertises. I’m at 5k ft elevation, maybe I should go a different route.

[@COMotorsports]

Could have been the car, we did no stock dyno comparisons so we have nothing to go by for comparison hence why I didn't touch on it much.

[@MaxiimTribe]

APR coilpacks is a mod? And R over S3/A3 but VW treats it like some mythical creature and does not build nearly as many as the S3/A3 platform.

[@COMotorsports]

We've made well over 500whp on multiple cars with them, however stock work also.

[@ChargedTTq]

What's the longevity on setups like this? Im looking at a car with 126k on it, same build but with a gt2260. My local Audi guy (Rathana at Ratified) is becoming a bit averse to big power ea888 builds. Both because of the eq250 and he said hes seen a couple with cylinder issues. But we've got some around here at 600hp.

[@COMotorsports]

Anything's possible, but with proper parts, proper tuning they're great.

[@patrickpl94]

Hi, I have a MK7 R with the APR DTR6054 setup. My setup includes the HPFP and the LPFP from APR running on 93 octane. Mine dyno'd at 399whp. I am looking to go down the custom tune route from EQT, similar to what you've achieved here. Comparing your results to mine is very apples to oranges, considering the variance in fueling, and hardware.. so my results might vary, however adding that much power with just a custom tune is fantastic and very promising. Do you guys have any of this guys time slips from the 1/8th mile? Maybe a before and after? Did this car also get a DSG tune from EQT? Or stick with with APR one?

[@COMotorsports]

Still APR TCU Software, car just ran 7.3 in the 1/8th last weekend the exact way it's driven. He thinks there's a little more in it.

[@patrickpl94]

Very cool! When you guys originally dyno'd it with the APR tune, did you notice power output variances specifically dependent on the IATs? The reason I ask, during my experience with the turbo and APR tune, the performance varies drastically depending on IAT.@@COMotorsports

[@COMotorsports]

@@patrickpl94 Not on the dyno as it's pretty consistent but I do know IAT can play a large factor on these.

[@TheShameous]

@@patrickpl94 so it is best to use cold air intake with DTR6054? Im on 91 map making 390whp with open air intake. iat was 45c-40c during dyno.

[@UngluckInc]

You guys ok?

[@evanbouchard7531]

Where are you guys located?

[@dougdevine]

I know y'all dyno them in fwd but what about would the numbers be at all 4 wheels?

[@COMotorsports]

If it's dyno'd on linked dyno to keep the car happy, then basically no different as the only time the rear wheels are engaged is if the front wheels are spinning (loss of traction).

[@BrendanDalponte]

S3 for me.

[@spbunney]

The golf doesn’t come in a two-door convertible

Well I got an R so I'm gonna say R plus I like the manual. Wish Audi would let VW put the 5 in the R.

[@volkssturm9694]

not true at all, the Golf R comes at a premium price...the Golf R is considered the "top model" of all VWs, plus the demand, the price is approx. 5-8 grand more given the equivalent model audi S3, Golf R. The Audi S3 is definitely the better value. Ive driven both and shopped for both. Don't get me wrong, the Golf R is amazing as well , it will be a hair faster since it weighs about 300 lbs less.
