B9 RS5 Upgraded Intercooler

[underboss24]

Hello,

I've been looking into upgrading my Intercoolers as the heatsoak is starting to make me more paranoid. It looks like there are one commercial off the shelf product. What are everyone's thoughts on the upgrade? anyone with either of these products?

Waiting for this too.

Has anyone upgraded theirs or maxed out the factory one?

I saw an RS5 with the MTM system.

Its a complete replacement of the stock unit. The ABT one looks like its an additional one to work in line with the stock unit.
The car that had it on had MTM 575HP kit, the owner said that even with the added power the car seems to heatsoak less than stock.

Hi,

I just posted some information on this product from us in the following thread:
https://www.audizine.com/forum/showt...e-from-MTM-USA

Our system is an upgraded intercooler that replaces the original unit from Audi. We designed it work with our Stage 2 Upgrade and have made it available for purchase as a standalone for those who live in warmer climates where the car starts to really suffer from heat soaking.

[RLB6]

From what I've read and the tunes via piggybacks (JB4), the OEM intercooler is maxed already. An upgrade unit is mandatory, IMO.

[Hibnah]

What’s been proven in the MTM one other than they have it for sale ?

Coming from an F80 M3, with insanely over-engineered OEM cooling, I knew my first real mod on the RS5 was going to be an upgraded intercooler. My B8.5 S4 needed upgraded cooling to prevent from losing noticeable power in the warmer months, even with stock power. I fear the RS5 will be similar.

While I'm sure the MTM unit is nice, $4.2k for an intercooler is bonkers. Hopefully more competition will come to market soon.

For what it's worth...I was talking with APR the other day and I asked what the weakest point was on the RS5 as far as adding power. His response...Cooling. He said the transmission, internals, etc. can handle lots more power, but cooling would be the limiting factor.

[Rob01S4]

I would go with a custom fabricated sheet aluminum cooler and get a larger capacity heat exchanger kinda like that GMP offering.

Danny - Did you end up going forward with that setup? If so, any updated input for us?


...........
Stanfa mentioned that APR already knows cooling is the biggest weakness. I'm hoping someone at APR (or other reputable tuner/parts supplier) can chime in about any plans they have for cooling upgrades on the B9 RS5.

I wish it was the same cooling system as the B9 S5/S4, which simply requires a $1000 upgraded core unit and some tubing (LINK). If that was the case, I would have purchased it before I even took delivery of my car 2 weeks ago. Unfortunately, the RS5 cooling system appears to be much more complicated and significantly more expensive to upgrade. Hence the $4.2k option from MTM.

With the summer months approaching, I'm really hoping we start to see some more info/options from APR and others.

isn't that just another radiator similar to the one ABT sells for their power upgrade? Sits in front of the current radiator?

Yes but the B9 Rs5 intercooler is at least partially water cooled. introducing more water to the system and increasing cooling efficiency can make the factory cooler work more efficinetly and keep IATS down without having to change any hardware yet.

[ECS Tuning-Audi]

A lot of my guys are going along the path of methanol injection to keep ITAs under control while we wait for the intercooler upgrades to come out. I'm a big fan of the Snow Performance stage 2/2.5 kits, they're pretty simple to install easy to operate etc.

^ Correct. This is the same type of cooling setup the B8/B8.5 S4/S5 (and possibly other models) have. Instead of slapping on a new intercooler and some tubing, you essentially upgrade the heat exchanger (radiator) setup to help keep the coolant temps lower as they flow into the intercooler core. Unfortunately, it also comes with a more complicated install as you have to deal with draining/refilling and re-pressurizing the coolant in your whole system. I performed this same type of radiator upgrade on my old S4 and while it's definitely manageable, it's much more complicated than typical turbo intercooler installs.

It is what it is though, I suppose.

Yeah I did the same thing with the Merc racing setup in my b8.5 and it was a bit of a hassle especially with those garbage plastic bleed screws on the charger.

I forgot about those bleed screws. I know a lot of people had issues. For that install I purchased a coolant system bleeder/pressurize tool (Amazon Link). It worked wonders and prevented me from having to deal with those brittle screws. It's also great to have because it allows you to check for leaks before putting coolant back in and finding out the hard way.

It will come in handy again if I upgrade the RS5 cooling system.

[underboss24]

It's interesting hearing about the cooling options that will be available in the coming year. As you guys read in the NardoBuild build thread, the ABT additional radiator def helped but its far from a magic bullet.

[Sean@TAG]

We prefer to run the ABT setup with both Piggy back and their additional cooler. You can actually purchase by clicking right on the images :)

I don't see that additional cooler. on your web site.

I do see it here though: https://www.gmpperformance.com/produ...rcooler-system

[idrinkv8]

Would love to see some raw data on the ABT cooler and IATs after a few hard runs vs stock

[303 Spartan]

^^ Agreed. I'm getting quite intrigued.

[Sean@TAG]

The kit that we offer actually includes both. ABT does not offer the RS5 powerkit without the cooler.

Can you provide the data? Or is it on Abts site?

So, just to confirm... the link you provided above (also HERE) includes both the piggyback kit and the additional cooler kit for $2,622?

Is it possible to buy just the additional cooler kit from you guys?

I was wondering the same thing...

Correct in regard to pricing. Let me see if they will allow separation of this kit!

[Sean@TAG]

Ok, update here :)
We can in fact get the cooler kit separately. $1490 plus about $90 to ship in the US :)

See here for info on the complete package:
https://tagmotorsports.com/abt-sport...-power-upgrade
These numbers differ slightly in the US however as this is based on 93 octane.

Nice!

Now we just need someone to properly test this $1,490 cooling upgrade to determine if it has a notable impact on IAT's.

Let’s do it! Lol. Just need to have someone log it all!

[underboss24]

If your RS5 heatsoaks before mine then it works to slow down heatsoak. Spartan read my Build/ I explained it.

[Shawn@PacificGerman]

We have the ABT Charge Cooler upgrade on our RS5 and it kept temps consistent on the dyno during testing of both Stage 1 and Stage 2 ecu tuning from VF Engineering.

I logged the car stock and w/ cooler, but changed laptops shortly after.. Will find logs to share with the community soon!

We have done a few for customers on their RS5s also with the ABT Power Upgrade and its a nice package.

[the4siswickid]

Anybody running a special on the ABT intercooler system???

[MR_RS5_SB]

Shawn - ABT has a Power S upgrade (530HP) and looks like the only additional part is an "air intake cover". Is this some sort of ABT intake kit?

EDIT: Actually it looks like what ABT offers in the U.S. is the Power S upgrade (piggyback + cooler) but it makes less power than the EU version because of the lower octane fuel here?

Is this a cooler with an additional pump?

It looks like one needs 93 octane to see the claimed HP. From the ABT USA website: https://abt-america.com/tuning/produ...992405!17604D4

"Fuel type: RON 98 ( RON 95 with Power reduction)

Base
Power base: 331/(450) kW/(bHP)

ABT POWER
Power**: 375/(510) kW/(bHP)"

Allegedly;

RON 95 is the same octane as USA 91 octane

RON 98 is the same octane as USA 93 octane.

Yeah, looks like in Europe this is called just the Power Upgrade and to achieve it they only add the piggyback and nothing else. The Power S upgrade in Europe is actually the one that is the piggyback+cooler+water pump and makes 530HP but requires 102 RON fuel, which would be something like US 97 Octane. So looks like what they offer in the US is the Euro Power S upgrade kit but tuned for US 93 Oct and making less power.

This is all correct. The kit we offer from ABT is essentially the same, just dials back a bit producing less power than their tested numbers. Still, a very healthy upgrade for the cars her in the states :)

So it requires 93 octane fuel?
