Are there any power mods for the RS5 that are worthwhile?

[Optiondoc]

So my RS5 is now 3 weeks old, and I'm wondering if there are any worthwhile power mods. Also wondering if that PES supercharger turned out to be any good or should I just equate PES supercharger to POS supercharger.


Thanks.

No, no and yes.

There may be a new intake that adds some decent horsepower. Made by Eventuri but Mojo is right on with his answer.

[Optiondoc]

That's a shame. I mean, the car is fine stock but if we can't add power maybe a weight reduction campaign would be more worthwhile.

There's a few options available for the RS5, two of them seem to give a reasonable gain with no impact on warranty and the other gives not an awful lot of gains and will void the warranty.

Look at the new Eventuri intake, that should give you around a 15-20hp gain, it looks gorgeous and should sound great too.
Add to that a capristo exhaust or an exhaust which has proven gains, the only graphs I've seen are from Capristo and Akrapovic but they are both big boys toys at the $4000+ asking price.
Those two should see you with around 30+ HP gain for approximately $6000. That's a lot of cash for not a lot of gains but the tuning market is pretty limited for the RS5.
The APR ECU flash will only gain you a void warranty and not much else.

3 weeks old and already looking at increasing the power? Just wondering, what do you find so lacking with the car that you want to go ahead and potentially void the warranty over? Mine is about a year old and I love the Eventuri intake and the capristo exhaust and will surely get it as a 100K mile anniversary present to my car. Just after my extended warranty expires.

It's not so much that's it's lacking so to speak, but I would like the "pull" of the car to be stronger, especially the low end. It's nothing that makes me want to get rid of it, I absolutely love it. I just feel Audi came up a tad bit short on power or way over on weight. This car as is with an extra 100hp would be perfect.

I hear what you are saying, but the motor has always been known as a horsepower motor that delivers at the high end. Same as NA Porsche motors. Most high performance motors from Europe are.

The lack of effective tunes is not limited to this car. There are none for NA Porsche motors that are effective either.

Sounds like you need to change your driving style. Keep the revs up. The sound is wonderful.

None of these are WHP, so after power loss you're looking at very minimal gains. Nothing's in the market that's worth it, atm.

[Optiondoc]

It's a real bummer that supercharger never manifested. What exactly was the issue with the PES system?

With respect, kinda sounds like you bought the wrong car? 3 weeks into an RS5 and you're looking for more power - nothing's wrong with that - but probably should've gotten a turbo..?

[AirmattRS5]

Trade it in for something lighter with force induction if you want that low end power.

[Optiondoc]

Not that big of a deal, I just thought it would add to the fun of the car as well as increasing usability. Absolutely not getting rid of this car. Just look at it, and the high revving V8 is loads of fun, but an extra 100hp would be ideal. I've been driving our car clubs GT3, 458 and huracan so that insanely hard pull is something I'm hooked on. Would be ideal if this car had it.

The figures I quoted are all WHP figures.

[LINDW4LL]

Eventuri intake looks promising @ 19whp gains. Will be nice to see more impressions once people here get their's installed.

I think headers would give good gains as well with a proper tune. Kline Innovation offers a set, although they are $$$.



The RS5's headers are quite restrictive, as you can see below.

? All the exhaust companies are listing like 5-10 bhp, which equates to absolutely nothing in real life.

Are there even dyno's to prove Eventuri's 20~whp gains? Haven't been following that thread. I'm sure it'll sound "better" but I'm cautious of the results.

[chrissurfr]

Dyno charts are in the thread...19 whp gain.

Without a blower to make the torque you'll never get it.

Those headers look great! Where can I find more details? Would an intake and full exhaust system require a tune?

Most def. If your going to see any real gains you'd need a tune. I wouldn't run header back system without a tune, stock ECU only adjusts so much.

I figured that much. I guess I'll need to wait until the warranty expires to get the full set up but an intake and capristo wouldn't void a thing I'm guessing

I could actually see the dealer giving you shit on the intake. Exhaust no.

Think so? Any NYC area Audi dealerships better towards mods? I don't see how an intake would void warranty, but I'm not surprised should they try.

The real solution is to remove the radiator cap. Hold it high.
Drive a RS7 underneath and reattach.

Depends on your dealer. The intake most definitely will void your warranty. I see them being more lenient on the exhaust. It only takes one stickler dealer to put it in the system. Then good luck to you. I certainly do not want my warranty voided on this not so inexpensive car.

That's not how it works.

Please elaborate. I think there are a few of us that may take the plunge if it weren't for the fear of losing our warranty.

Yes please do. I'm wondering how an intake would void anything other than a mass airflow sensor.

OK, so no single modification can broadly void your car's entire warranty. If you were manually flagged "TD1" by your Audi dealership due to an intake (which seems to be fairly rare), then Audi would simply review any powertrain claims more closely.

For them to deny a claim, the failure needs to be a direct result of the aftermarket part. They CANNOT simply blame any engine issue on your intake. For example, if you had a coil pack failure, PCV failure, timing issue, etc... those couldn't be blamed on your intake and would be covered. However, if a foreign object or large amount of sand, etc... was ingested through the intake path and caused engine damage, they could certainly deny the claim as the aftermarket part played a direct role in the failure.


It may be wise to consult your service advisor if you are concerned as this is something that the dealer has direct control over- a technician would need to manually enter the intake into the computer system and send it to Audi for you to be flagged TD1. I think this is a fairly rare thing to happen. I've seen a few cases of it occurring on the S4 forum but many/most there leave their aftermarket intakes on for service and never have any issue.

Also, another option is to re-install the stock intake prior to any warranty work being done if your dealership is not mod-friendly. I'm not sure how difficult this is on the RS with the dual intakes, but it takes ~10 minutes on the S4 and may be worth it if you're not visiting the dealer often.

[NoMojo31]

It all depends on how badly the manufacturer wants to avoid paying the claim. If they tell you "sorry" you'll have to pursue legal action to collect. In that legal action you'll have to prove that Audi breached the warranty. To do that you will have to prove they are wrong and the mod did not cause the problem. At the end of the day, even if you win you lose due to cost, time and effort to prove Audi wrong.

I don't think the australian dude gained any power with the headers at all....

Please. Everyone states that bull time and time again from the Magnuson–Moss Warranty Act but we all know damn well the dealer/Audi will do as they please. You want to overturn their decision, lawyer up, and I assure you they have more money and time.

Thanks LINDW4LL for taking the time to explain. I'm taking my car in on Tuesday and I will check with my advisor. They are very reasonable.

Vanquisher- I wouldn't have the same tone if we were discussing something like an ECU tune or a supercharger. An intake is a very basic modification, just like an aftermarket exhaust. It's hard to blame many failures on it.

Did he say this somewhere? My conclusion was he said gained more torque and it came in on lower revs too. Idk

[doug97gxe]

trade it in.. get an S5

With how restrictive the stock headers look to be with the catalytic converter right there (and the added heat), I don't see how it's possible to not gain power. With proper software, of course.

Headers are not something I'd recommend to most, though. They are a rip as far as power/$$. But there are always those who want to go all out and have seemingly no concern over the cost.
