I emailed Magnuson about a supercharger for the RS5...lets see what response I get...

[chrissurfr]

Guys - I can't take it anymore. Since no vendor wants to go to bat and get us some type of answer or movement, I'm inquiring. I need more power. Let's see if they have something underway that no one has talked about yet....

I got an email back from an account manager putting me in contact with the head of their Audi program.

"Andrew handles our Audi program and he can provide some feedback to you. I have cc’d him in this email, thanks!"

[Alister]

Let's see if they have something underway that no one has talked about yet....

It has been talked about before - there is RS5s in existence with APR/Magnuson TVS1740s fitted.



The kit has just not been made available to retail purchasers for whatever reason.

[JoshDub]

Because the Mag/APR supercharger has been working out so well for the 3.0 guys.

[jkownz]

i always will be interested in a SC for my RS. I really hope over time someone takes on the challenge. I know we can push these motors with the proper mapping, fuel ratio and testing for long term reliability.

[Nanozic]

I was actually doing a little forum crawling the other night to refresh my memory as to why APR stopped development of the RS5 kit. The short answer (at least the public one) was that doing R&D for the kit was a "resource hog" at the shop. There are multiple iterations of the RS5 that would have required certain parts to be manufactured differently depending on if the car was LHD or RHD or B8 or B8.5. Also, and maybe this is what sealed the deal for them, was that there were concerns as to whether on not the factory cats would be able to handle the SC application. If installing the kit would also require installing new cats, that may have been too high of a number for people to pull the trigger on. 20k for the RS4 kit is already a pretty hard pill to swallow so I assume they were probably expecting it to cost more than that on a smaller market car. Probably not a good P&L to look at haha.

All that said, I had a Mk3 supercharged VR6 and have a turbo R32. I actually bought the RS5 because there wasn't any FI kits out for it so I knew I wouldn't spend gobs of money on it. But... for 700hp I could be convinced otherwise lol.

Cheers to you man, I'll be watching closely.

[chrissurfr]

S5 kits are advertised around 12k....I think that is fair.....

I think you are probably on the money on most fronts.

Standard cars have reportedly had issues with failing cats, which are likely even more of an issue where there is higher EGTs.

If it could be had for that, I bet it would fly off the shelves, since that's only twice as much as some of the exhausts that are out there for the RS5 with maybe a little bit more of a power gain . I'd be curious to know if the 'sale' price on the S5 and RS4 SC kits is because they are older stock and they are just trying to move them. Both those cars are 6+ years old at his point. Also, the APR R8 SC kit seems to have been erased from APR's history almost. It's gone from their site, and the Magnuson site says to "call APR" when browsing to the R8 kit. I just find it interesting and would love to know the story there. APR even removed their video for it from youtube. This should be a 10-part Netflix documentary series. :)

Companies are just coming out with their kits around that price (~10kusd), such as AMD and JHM. So they are hardly old stock discounted to move.

BOOM! Happy hump day!!!!!!!!!!!!!!!

"The RS5 (B8) program has not been cancelled, and we have a couple of hardware kits on vehicles still, however we are yet to move into full production. This is still an ongoing program for us! If you are interested in being an early adopter / part of the BETA program please let us know."

Okay, even though I am under warranty (less than 6 months old) I would gladly get a SC added once I'm out of warranty. So, how do we start a buzz and show them that there quite a few of us who are interested in this?

I ask because you did such a great job with the intake ...

The compression ratio is to high on these motors. 12.3-5 to 1. It way to high for a supercharger. Maybe 4 lbs of boost. Not worth the cost. These transmissions also can't handle the torque increase.

RS4 and R8 is the same thing...they run blowers

[chrissurfr]

New Hurucan has even higher compression and they slapped a blower on it...

It's a bad idea. Who is going to support the software?

[audirs5guy]

There's a reason the RS7 isn't using the DCT transmission that's in the RS5, and it's single clutch. It can't handle the horsepower. Audi has stated this publicly.

How much of a power increase will it take before it starts slowly deteriorating it? How much will it take before it blows it up instantly? Only Audi knows how much derating is in the transmission...

For people with enough money to add the supercharger, it probably doesn't matter. :-)

[Jimmy ny]

True. I would not be interested. I would just buy a faster car.

I didn't expect many gains from replacing one supercharger with another. This would be quite different since it would be adding a supercharger to a NA motor.

There have been many cars running the PES supercharger with well over 600hp, no transmission issues reported. Caudy is one of them and he definitely pushes the car with no problems so far. The only issue I know of is the guy in Australia who blew his engine, but there was a lot of controversy as it seemed the car wasn't fully tuned properly and he was missing new key components, one of which is was a HPFP. But no transmission issues that we have heard of so far.

[Optiondoc]

I agree with James New York. Not saying if a kit comes to market at a reasonable price that shows it won't blow it up ala PES, I would probably take a look at it. This car with these good looks, sound and an extra 60-100hp would be the tits

So you're saying that once an engine has forced induction there is no longer anything you can do? Lol OK.

Small gains weren't even the issue there. Stage 3 cars (upgraded sc) were performing worse than stage 2 cars (stock sc). Poor SC selection along with other issues on Mag/APRs part.

before you get discouraged Chris by the information above.. the issue with the 3.0T Kit is because 1) there is enough cooling provided to make good power on the kit 2) the 3.0T isn't a viable motor to drive the 1740 to get good numbers out of..

if you want a good baseline of what it will do on an RS5 i would suggest looking at the successful RS4 Kit.. this supercharger is perfect for a v8 motor..

[doug97gxe]

here is a video of a bunch of audi's doing parking lot pulls.. you will see the B7 RS4 is the fastest of all the cars.. its supercharged.. most of the B8 S4's are Stage 2.. just for comparison




edit.. the SC RS4 doesn't show up till 5 mins into the video

[chrissurfr]

I am 100% open minded to whatever magnuson brings to the table. I've watched the PES issues for a while and all I've seen is the Australian guy who blew up it because he seemed to get a crazy custom tune and had no high pressure fuel pump. No transmission issues to date. I think a conservative kit that doesn't try to max out the motor would be great.

Not what I said. Obviously just tuning and a pulley showed significant gains. I'm not saying there's nothing you can do once supercharged, but how much can you really get out of it by slapping another supercharger on it? APR should not have even bothered trying to put another supercharger thinking they could get much more out of this engine. And when they couldn't do it, it seems they just gave it to Mag to come out with something, anything just to get the project completed. In the end, they just haven't improved on something that was already good.

actually it appears APR noticed it wasn't worth it and scrapped the project.. Mag picked it up and said just do the tune.. we will market it as our kit.. they are just now realizing that the stock cooling system is not enough to stop the ECU from pulling timing.. but apparently they have reworked some hoses and ironed out some issues.. no results yet though

I'm in for a reasonably priced supercharger........ :D

[Nanozic]

That's a bummer. I've been itching for a little more power (for really no good reason, lol) but maybe I'll just have to wait the 2-years for the next RS5? A buddy of mine has a TTRS which he just went stage 3+ on. Car is ridiculously fast now, but the TT platform is just too small for what I want. I really like the RS5, it's the perfect size for my needs, and definitely hits my check boxes of comfort, luxury and style. Just wish it was a little bit faster, but don't we always .

At least chrissurfr tried

LOL these guys are my friends .... Most of them are Stage 2. Some are Stage 3 with the Magonson Supercharger and Some on E85

[mufflerman]

Anyone looking to do this should ask what your expectations are with the car besides more power. We've built a lot of high power cars at the shop and my experience with adding power to a car that has such good balance stock is a bad idea. If your just looking to go faster stoplight to stoplight or have better bragging rights on a dyno day, then go for it. However, if you want your car to work as well as it does now in all environments, get ready for a lot more then just a supercharger. To start with, brakes, suspension, transmission, tuning, more aero, etc. Remember, for every action there is a reaction.

while i agree with you on the concept, i think the RS5 comes with pretty good brakes for 500 hp.. and H&R Coils are already excellent to handle that kind of power .. now if a guy with a stock A5 wanted to go 500 hp with stock brakes and suspension.. then yeah.. i can say definitely

Agreed, the brakes are pretty good, and plenty to sustain regular street driving with a few high speed sprints thrown in. All I meant was to consider the other things involved when adding 20% (+-) more power to a car that was put together so wonderfully from the RS division of Audi.

[JamesRS5]

I certainly won't be looking for dyno bragging rights car, I just want more torque available at lower revs so you don't have to kick down 3 gears and hit 8000rpm to overtake the mail truck.

I've covered all the other bases, chassis and brakes, intake and soon exhaust, just needs that little extra oooomph now.
