Audi S4 v Audi RS4. Does Supercharging Rule? - /CHRIS HARRIS ON CARS

[@MrRyanMcCall]

The S series cars DO have launch control but it's hidden, press and hold the esp button for 5 seconds, put it in sport, foot hard on the brake then hard on the throttle. You'll have 4 seconds of 4k launch mode before it will cut off so you have 4 seconds to launch once punching the throttle. Just lift right off the brake to launch

Will this work on an '08 S6?

[@jasonholtkamp6483]

Sounds crazy that a software change could have that result, but then again, remember that Audi may have intentionally de-tuned the S4 slightly so that the RS4 would be a significant upgrade.

[@tumdeax]

+Jason Holtkamp Maybe not. I can bet surely that the S4 can't pass an emissions test.

[@jaybomb5022]

+Jason Holtkamp If you saw the revo kit, they add a supercharger belt and pulley, and intake along with software programming. Its very misleading with that little DLC connector because he only used it to change the current tune used by the ECU

[@adamakesson2225]

I guess all commercial car engines are a bit de-tuned. If you max them out , they woldn´t be as reliable. The tuned engine of the s4 will probably have some problems in the near future.

The S4 B8 was an incredible package from the day it was launched. And by the way Chris, you can re-tune the gearbox software too, it will enable LC and a lot more features, after that it will be faster then the RS4.

Awd so good for all weather, insanely reliable, makes great power and torque, plenty of room, looks great inside, looks great outside too but doesn't draw too much attention which is nice when using daily, AND it actually gets pretty good mileage too. Even with a stage 1 tune I can still get 25 mpg

[@darrylm79]

This is similar to BMW and how they under rate their motors. Take for example the N54 on the 3 series 335i, stock is 300hp, when you had a $479.00 piggy back tune to it, you go up to almost 370hp - just from the tune, not mentioning the down pipes, or the inter cooler or intake. The Germans really know how to squeeze every last bit of performance out of their engines. These are sleeper cars.

[@DeeJayAdverb]

actually BMW rates accurately. If you pout them on a dyno. Mercedes and Audi underrate them on paper. Do some reading its interesting.

[@GewelReal]

Have you seen the 114i? Its the same engine as 118i but stupidly toned down. Just by remap you go from 102 to... 200 BHP!!!!! (my friend did so like 6 months ago and no problems what so ever. The MPG even improved (by only 10-15% but still)

[@lewiscarpenter8931]

+mahunik Not a lot unfortunately. RS4 is a NA engine, so tuning potential is extremely limited. Companies quoting more than +10BHP for a stage 1 are probably over estimating..... Adding a pulley upgrade and going Stage 2 on the supercharged V6 gets even more silly...

[@bayonet262]

yeah i was mistaken I thought they had some turbos on the newer Rs4s. but yeah pretty much any naturally aspirated wont get much power out of a tune.

[@musclecarfan1]

William, this was a comparison to show how close these 2 cars can be in terms of power output with just a little bit of money/tune thrown at the new 3.0 Supercharged Audi engine. For the small investment needed, an S4 owner with the supercharged power train can end up with NEAR RS4 straight line performance. Any RS owner will likely still frown upon such statistics as there is more to tuning than simple power output. I own a 2010 S5 "Daytona Grey" Coupe (4.2L 8 cylinder) with the 6 spd manual transmission (perhaps 1 or only a handful ever built) and i love my 8 cylinder engine regardless of what tuners can do with the forced induction power plant. My 8 cylinder makes erotic and awesome noises the 6 cylinder could only DREAM about. Tis the wonderful difference between so many of the automobiles we car enthusiasts own...sound, performance, looks, branding, etc. Great video Chris Harris..keep them coming!!!

Every single video that includes something related to Audi there's 90% of BMW and Mercedes fans saying that their fav. automaker is "way better than Audi" and I'm quite getting tired of it, most of them come from places like the U.S., where Audi isn't really known for what it is, I've had the chance of driving a 535i (it handled nice but it was like if it's engine wasn't there) and a MBenz E350 (I have to confess that it was a really nice car) but the Audi A6 is the one I kept, it has lot of safety features and lots of technology. For all those who are saying RWD > AWD I reply to them "Really? did you even get your car to its limiter? how many times when you are driving on the road did you exceed 200 kph? And why would you even need so much acceleration? (FYI 2014 Audi A6 3.0T does 0-60 in 5.7s when the 535i (non xDrive) does 5.9 s) Search youtube for Nose - Tush or even standard drag races between an A6 and a 535i, then come back and comment.

[@farooqwaraich]

I also had my 2008 1.8 TSi VW Passat CC tuned by Revo Pros: + Lots more power and a MOUNTAIN load more torque!! It gives the car the power to match its looks, and goes faster than say a Golf GTI now. + Even better fuel consumption than standard while cruising. + Harder/snortier engine note. Cons: - The extra pressure created caused several air leaks in the turbo piping (my car was only 4 years old with 60k miles) and more than a £1000 pounds later trying to get it fixed at various garages.. a leak still pops up somewhere after a few days. The leaking air causes power losses and car jerks under acceleration. I'm depressed and have given up trying to fix it, I just don't accelerate the car hard many more. And no one wants to buy it now. - The Revo remap only runs on RON 98+ Super Unleaded fuel. - Black smoke through exhaust. CONCLUSION: Just buy a fucking BMW 330i or M3!

[@Beer_Dad1975]

Sorry to hear that, seems these guys don't bother to tell their customers about the consequences of re-mapping without supporting mods - happy to take peoples money and run I guess. There is nothing wrong with tuning, but to make big power you have to do it right - just changing the factory maps to output this kind of power without adding supporting mods to keep the car healthy is always going to end badly. My advise, find out what other owners of your specific type of vehicle have done, and what problems they have had before you do any tuning. Owners groups are usually the best place to start for advice on what upgrades you need to do before messing with boost and mix.

[@Beer_Dad1975]

***** BMW don't sell the 2 series in M trim where I live (not sure if they are ever going to), plus it's too small for my needs - and not keen on Subaru, sure great performance but too ugly on the outside & cheap an nasty feeling on the inside - thus I drive Aussie Ford muscle - loads of power and luxurious enough too.

My point is that I work for my money, therefore what I spend it on is valuable to me, therefore I look after my stuff.

[@Beer_Dad1975]

Indeed, just because you can do something doesn't mean the stock engineering can deal with it. My car stock had 270kw/550nm, you can change the standard mapping and get 350+ with the standard kit & it'll run fine on pump fuel for a while, but if you don't add some supporting mods in - bigger intercooler, uprated injectors, cat-back exhaust as a minimum, you are not going to have a reliable car any more. Generally OEM turbo setups have a little bit of overhead in them, but if you push them this far without supporting mods, something has to give sooner or later. This was filmed over a year ago - I wonder if the car is still running?

We tested a S5 Sportback, basically the same car as the S4, with and without the Revo remap, it also had 100 ron fuel and aftermarket air filters. Results? Stock: 350hp. Revo-ed: 434hp. Once we finished with it it had 448 hp and it was way faster then the RS5. Obviously I would at least double the oil checks...

[@The.JZA.]

I must've watched this video 10 times by now. I have a B8.5 S4 and I would love to get it Revo tuned but there is only one company in New Zealand that does it and they're a couple of thousand km away from me. Oh well, even in stock form it's fast enough to get you in trouble so I'll just have to enjoy it the way Audi made it.

[@zippycentral]

Contact Peter at superchips nz. They’re on fb. Had my Q5 tdi done and made big improvement. Just got an s5 and doing next month.

[@The.JZA.]

@@zippycentral Cheers. I had a look at his website. Does he make the tunes or is he selling Revo/another brands tune? Revo, I.E. etc spend thousands of hours developing and testing their tunes to ensure the best balance of performance and longevity of the engine. I remember reading somewhere that Revo had bought an S4 and done thousands of km of testing on it to make sure that the tune was as good and safe as it could be. I found an NZ based website called "alittletuningco.nz" that sells Integrated Engineering tunes for the S4/S5 for $1630 including the dongle that you need to load the tune on. I think I'll go that route if I decide the bite the bullet.

[@shaunald]

Go with APR tuning instead. The founder of Revo is a former employee who stole their technology, You can read all about the lawsuits on the APR legal page. I have the APR ECU flash in my S4 and its a freaking rocket.

[@guerrillawarfareracing7352]

What year is your S4 and how much did all of your mods run you?

[@shaunald]

***** Not at all. As a business owner with proprietary intellectual property of my own, I refuse to support a company that infringes on copyright laws. Besides, I am extremely happy with my APR tuning and will always recommend something that is tried, tested and true. Whatever your choice in tuners is, you'll be happy with a tuned S$. I just have business ethic standards that are not in line with REVO.

[@chellae2]

Where the fuck was this video when i has my s4😅 smfh

[@JoshLaskoPhotography]

These tunes are common knowledge to automotive enthusiasts and have been available for Audi's and VW's for a long time.

[@VioletGiraffe]

That's chip-tuning turbocharged cars for ya. But you still need hardware mods to get *real* power boost. For instance, if you started with A4 rather than S4, you'd have to replace injectors, intercooler, and probably the fuel pump. Of course, you started with an S4 which already has many things upgraded.

[@imsmokingcheese]

It's supercharged

[@VioletGiraffe]

imsmokingcheese , right. Doesn't make much difference, except you need a different pulley to get more boost from SC.

[@Make-Asylums-Great-Again]

What’s with the what if comments?

[@johnmoriarty7331]

CH is the only reason I still watch TG 👍

[@almarnordby2034]

I remember seeing this video eighth years ago and thinking: damn, i want i S4!. Now i own one just like that

[@TomRopez]

Let's see Chris Harris get the new stage 1+ upgrade with DSG map and then run this race again.

[@RogueBrit]

Should have gone to MRC Chris

[@ludovicomarchisio8874]

please give it to AMMO NYC

[@shauncarlpope33]

Chris your stuff is so consistently brilliant and I get to watch it all for free on here. Thanks!

[@MilGrip76]

Thank you for this! Buying 2012 S4 @ a lovely price care-of depreciation. Cheers Chris!

[@ImDembe]

I look on compares to this, a company in Sweden that use MTM tune say the stage 1 tune from them give the S4 100hp+ and 100nm torque for around 1000€, also included is a gearbox strengthening if you dont have manual and they take away the 155mph speed limiter.

[@legibby]

Brunlera SAME TUNE - ALL BASED ON THE ORIGINAL APR TUNE...YOU'RE LOOKING AT A B8.5 S4 RATHER THAN A B8 - WHICH THE ABOVE IS

[@ddtonni]

I just wanna find out what's going on with the S4's tail light.

[@ivorproblem1332]

Shutter speed of camera verses pulsed output of the led drive circuit

[@bmos02]

I feel like you should have tuned the RS4 as well to have a more fair comparison...

[@bmos02]

*****​ I'm not saying it'd be a big improvement but it definitely can improve the character of N/A engines significantly even if it doesn't give huge torque/HP gains.

[@noquierounusuario]

THAT wasn't the point lol....

[@bmos02]

Maximus Decimus Meridius​ considering how close these cars were, it seems very relevant. Engine character has a measurable impact on such a test. I'm not saying the RS4 would win, but it'd be a much more fair comparison.

[@noquierounusuario]

Price + that takes the taco

[@noquierounusuario]

he never saw it I think lol

[@zerofuckkksgiven8027]

S4 3.0 upgrades now, tuning, pulley upgrades, exhaust, intake, e85, upgraded heat exchanger, will smoke that RS4.

[@teamemusrcreviews3225]

I purchased a 2010 S4 with revo st 2 on engine and gearbox, induction kit and miltech exhaust, heck it’s fast!!! I’m not hard on right foot but it’s apparently at 470bhp and is a beautiful car to drive, so firm on the road and responsive with supercharger👍👍🚗🚗👍👍👍

[@robeszr]

Never mess with a ,,sleeper''

[@stewarthumphreys8960]

amazing result ..

[@walidazar5180]

most gorgeous cars everyday use rs3 rs4 rs5 rs6 rs7

[@kwhat1159]

And hence the reason I searched and searched and searched and bought a very lightly used, beautiful, B8.5 Manual Tranny S4 (A rare find now-a-days). Time to start the mods on it.

[@nikolajnb3774]

Carefull with the manual.. Tuning it will not be healthy, stock manual can not hold that amount of torque for long. And upgraded manual is very expensive. If you want to tune it the auto is better

[@darkforcex7362]

my a6 quattro with the same engine pushes 700 hp. the 3.0t is such a great engine for tuners

[@ltg8382]

That S4 looks disgusting. Some people just don't give a shit about anything.

[@nightrider6976]

the b8 front end looks so much better than the b8.5

[@LeeDeFontes]

Um...no

[@Lucarocks92]

@ Akhe Naten, M cars are the best driver cars lol. AMG cars handle like dogs i dont know where u got that BS from. The last gen M3 from 2007 beat the current gen of Audi RS4 around a track the BMW even had 35 odd less horsepower. Nothing can match an M cars performance BMW are the benchmark and have been for quite some time

[@sonydhadwal7121]

I think you are mistaking BMW for Porsche benchmark.

[@cstavro]

Assuming a 4100 lb race weight (3,945 lb curb weight found on the audi forums), 115.8 mph works out to around 500 bhp. Congrats on your purchase!

[@turbobanana]

Most likely what they did was install multiple programs into the ECM and use the small DLC module to switch the programs. The 2008/2009 ECMs are the same.

[@manc7808]

Hi Chris, I watch all your videos but Ive been back and watched this many times as its so good. what ever happend to the old girl ?

[@stevenkempdotcom]

I saw it for sale on eBay a few weeks ago.

[@manc7808]

+Steven Kemp Ok thanks, any ideas of what it went for ?

[@stevenkempdotcom]

i didnt really pay attention, but think it was £18-20k. All I remember was thinking it was pretty much what Chris says in the video he paid for it 3 years ago! All the bodywork and interior had been fully refurbed though.

[@realtywithseankemp9704]

+Steven Kemp Hello Steven Kemp lol

[@funkynoodles6376]

I bought it from the dealer that bought it from Chris. The car was stripped and all the wheels and the bodywork was done with pretty much a full re-spray. Now, it's showroom and is my daily.

[@meteormedia7021]

Poor old S4...

[@meteormedia7021]

I felt sorry for it because its so beaten up and scarred.

[@JinglePeeny]

1200$ just to plug something in an ecu... wow... hard labor there.

[@93ariebombarie]

they had to develop the software. that´s not cheap, trust me

[@thehenchdude11]

Thats actually a bargain considering the fact they have to figure out what the hell the ECU is telling the engine, finding the limits and then writing the software in a way that makes it work EVERY-TIME.

[@JinglePeeny]

Daniele Dal Col developping software is rather easy when you know how to do it.

[@Kevinplaystsb132]

Sth29Productions So does spelling.

[@mdtsstuff]

yeah i mean.. just the plug.. the dyno time, the research into the bespoke little electronics in the sps, the map, the tweaking, the profit margins on top of that, it all adds up

[@peterblake5633]

Awesome vid. Just got my car REVO tuned a couple weeks ago, very fun. Put down 350whp (stock was 300whp), not bad at all.

[@quentin818]

Brilliant video, I’m sold on the s4.

[@Doa744]

how long will the car last with the tune?

[@Doa744]

danturbo316 do they share the same gearbox?

[@Borderline5440]

7:08 is just beautiful.

[@juliank911]

"we're just pegging each other" hahahaha

[@simonlindbo1610]

The engine will still last because its not being over stressed. Car companies always limit engines to fit rules or simply because they need it to be slower. In this case as Chris says, its made slower so it doesn't compare to the RS4. But the tune up means the engine percentage capacity is simply turned up a bit, without going too far.

[@alexanderranetkins7233]

about to pick up an a4 s line estate. So wish my budget was a little larger to get the s4 instead. Even with the battle scars, I'm loving that gorgeous red estate. I understand that this is an old posting and video but Congrats all the same! :) She must be a delightful yet bonkers to drive after your tune and add ons? Wish I was buying that one. Cheers!
