Finally! The 653hp Audi RS3R MTM 8Y - Detailed video + Wallpapers

[Auditography]

Hi there.
It took a good while, but finally the new RS3R MTM is out. 653hp is quite insane, and I had the privilege to be the first one to test it, and I took it to the Austrian Alps. Enjoy the video and the wallpapers. Thanks!

What did they do to get 653hp from that?

[lemonvr6]

Details are overwhelming

[DarthBalls]

Car looks amazing. So I'm assuming MTM was able to crack the ECU? Limited details, but I believe they noted a "retuned ECU/TCU" in the video? The other modifications seems to be standard to what others have done, but getting to 653hp, I'm assuming the ECU must have been cracked. Good news I'm guessing for everyone that has been waiting?

[TToysRuS]

3.08 sec to 60mph with 654hp? Wondering if they are doing boost by gear and limiting down low to protect the drivetrain etc (and traction limited).

Usually I would say yes, but it looks like in this case:

piggy back, hence why likely the TCU is limited too

[Jetdriver]

653hp with a piggy-back? I am thinking that is over-inflated crank power and not to the wheels. Could they get that much power without ethanol with a piggy-back? I doubt it.

[tf02]

What's with the power and torque numbers in the video?

"653 HP - 750 NM - 360 LB FT - 480 KW"

653 metric horsepower (PS) is 480 kw. But 750 nm is 553 lbft. Where is the 360 lbft coming from?

[RudyH]

ok I m not sure if their site changed, or I just completely missed it, anyway better goto the German site since its more up to date then the USA site

https://www.mtm-online.de/en/configu...ing/RS38YL294Q

looks like a turbo is in the list too

[dillybacon]

wow! $40k usd installed for what is essentially a tte700 93oct power level setup. i hope that means they know they have the market cornered for the moment and not that there is an insane amount of work to get the ecu to behave. hoping the rumors of apr and unitronic developing tunes are true, need to see some 8y's out there making power

It's a simple typo of 360lbft which is the stock number of the RS3. 750nm is 553lbft yes.

I've noticed MTM is a little pricier in certain areas than others, plus you get the "AESTHETIC" package.

[nate.co]

Heh, nice to see MTM again! I had a 2000 S4 with MTM stage 2, my first Audi tuning experience. Blew up that TBB and had to replace both turbos, good times :/

That being said, $40K is insanity

You'd be right. In European countries they tend to continue to advertise using crank horsepower (BHP/PS) as they modify vehicles instead of using WHP. It seems super counterintuitive to Americans because we are so used to seeing WHP. This is a common thing even for their naming convention of products. My TC800XT was never designed or intended to make 800whp but, on a very optimized setup, it'll potentially make 800BHP/PS-ish. However, I did manage to massage 800whp give or take from my TC800XT. The same goes for the TTE855 and anything else that comes from Europe with those naming conventions on it.

I bet you this 653bhp car likely makes somewhere around low 500's (520-540) to the wheels at best. That 0-60 seems awfully indicative of that, too.

Spot on. Also may be some boost target limiting in earlier gears for traction but overall I agree. Zero chance they are pushing 650whp on a piggyback.

Fuel is also a variable - essentially no one is pushing more than ~550 whp on 93 pump gas

E85 needs to be rotated with normal gas to mitigate sludge buildup. Not sure I would even consider a used car running E85 unless I knew the owner well - I suspect many of these engines will look like hell after tear down
https://www.youtube.com/watch?v=bPcVBc4-5Mk&t=539s

There is ALWAYS a price to pay for running these extreme boost levels. A ZL1 will make ~800 rwhp on 93 pump all day. Not sure about the new M3/4

[lemonvr6]

I wouldn’t use a Subaru engine as a barometer for anything

[Jetdriver]

I'd never run a tune that required E85. Aside from the above issues no one wants to deal with in their $65k+ car, here in NJ, we don't have many gas stations that sell E85. I thought about it, but I'd have to store it in my garage in 5 gallon race jugs. I will "settle" for something around 450-500whp on 93 octane when I get my 8Y. If I get sick of that, I'll pick up a G80 M3c before BMW stops making it in 2027.

Luckily where I live, e85 is plentiful. I've been e85 only the last 20-25k miles and it's been very fun. Currently have 88k miles and still going. Is there a reason you want to stay away from e85 or do you mean e85 only tunes vs a flex tune like from DS1?

If you go Uni Stage 2 and grab all their things, 93 for me put me at 470whp at 6800 rpm, and 495wtq at 4100 rpm. Going e85 put me at 550whp, but 515wtq due to it being a stock motor. Safety limitation things. You definitely feel the difference in low end torque and spool up. Very very fun.

[lemonvr6]

Even with the internet panic around ethanol I’d take my chances with it over cat-piss regular gas. Detonation is bad. Maybe if I was willing to run 100 every day

Yeah I’m in Southern California and E85 is very available. I’ve tested quite a few times and it’s only been E79-E90 content. It’s amazing and really provides an extremely noticeable power increase on a tune optimized for the e85. Even on my stage 1 e85 tune it’s insane. Been running it 10k miles and don’t see myself reverting anytime soon. The 91 gas in California is awful and being tuned on that 91 will most likely bring an issue before an e85 tune would to be honest.

100% agreed. I feel like handful of engines that failed due to stage 2 e85 tunes that pushed slightly too much torque, exacerbated the “danger” of e85. Or from the people who ran e85 too long on higher mileage cars that caused leaky injectors

Most of the zl1 guys are running e85 (or a at least some blend of ethanol) at this point

It makes our cars so fun. The only downside is the mpg are terrible. I get like 11-13 around town

I literally had this happen with my injectors. I somehow melted the teflon retainer on cylinder 4 and slightly on 2. Was causing my injector to bounce in and out of it's socket. Had the new revision injectors installed and back to the show lol. I also got a black forest report back and hlaf the engine torn down to see if there was any damage. I don't know what I'm doing right, but my engine's current "rating" would be that of a stock 25k-30k engine. But I also change my oil every 5500 miles, ceratec every 30k, and I don't push it until it's at full operating temp. But even then, that seems so little to keep it in such great shape when generally beat the hell out of it on the daily.

Hopefully nothing wrong with your engine. I have heard the retainers can get melted which isn’t very good. I’ve been on my e85 tune for 10k miles and I’m at 41k miles total. Thinking of putting in the new revision injectors at about 50k miles. Hopefully not melting issues until then. I do plugs/oil every 4-5k miles and don’t push until it hits operating temp either. It’s my daily as well. How did you figure out that the Teflon retainer had melted?

No detonation near stock boost levels

I wouldn't call it panic, E85 leaves sludge/deposits in the engine that aren't noticed until you actual tear it down. If you're not planning on keeping the car a long time maybe it doesn't matter, but I won't be buying a used car with significant E85 use now and I expect these modded cars are going to take more of a hit in resale value

Lots of 600+ hp claims out there, but not many second hand buyers

[8STTRS]

I make it a habit to run some pump gas through my car. But, I don't think I'm your typical owner. Not only do I actually keep up on my maintenance, I also don't dog my car. I daily it and have made maybe less than 20 full pulls on it since the build was completed over a year ago. It's mostly just seeing regular commuting and every once in a blue moon, some spirited driving--even less frequently, it'll see a full send. But when I do race it or send it, I typically also log it and send the logs to my tuner for him to ensure everything is good to go. Even on full pump gas, I'd wager the car is making around 550-600whp. I don't need the extra 200-250whp while I'm just putting around town or heading into work. While I enjoy it, I know that the more I ask of it, the quicker it'll wear down and need to be refreshed. The build done on my car and my wife's car was prefaced around the fact that these would still be our daily drivers.

Factory tune on gasoline has a ton of timing correction. What do you think initiates that, exactly?

[Jetdriver]

The ability to run with 91 octane and different qualities of fuel. I think the difference between 91 and 93 octane in the 8Y is at least 20whp.

I'm not sure you have a point, yes modern ECUs all incorporate knock sensors with varying degrees of sophistication - my point is detonation isn't going to happen running quality 93 pump gas (I only run Shell 93) at stock boost levels. The "cat piss" comment sounds like something an insecure 22 year old punk kid would say

Many people don't have access to E85, and don't want to deal with corrosion and/or sludge accumulation issues - run at your own risk. Rotating it is probably fairly safe but it will reduce engine longevity

I know we've spoken extensively but, he's not inherently wrong. Even with quality 93, at least on the 8S TT RS and the 8V RS3 (things might be different for the 8Y), the car will simply pull timing. This is why a lot of folks, even car reviewers, will put ethanol into the tank on a pump gas tune or stock tune to get the car to stop pulling timing. Now, how much power is being lost? I guess that depends on the quality of the fuel at hand but, it's been a well know thing with these cars. There's plenty of logs/documentation that covered this issue but, the vast majority of people would probably not even notice it--essentially saying that the power difference may be negligible to most but still present nonetheless.

[lemonvr6]

I wouldn’t evaluate timing correction only through the lens of reduced power. On the stock turbo, shorter OCIs are well worth it for the benefits of oxygenation and a basically knock-proof fuel

Or you can batter your rotating assembly pushing the edge on unleaded. Not my car.

Feel free to refute with something other than a garbage Subaru engine that was treated improperly
