intercoolerss

[shayan_a4]

hey guys so i just got a golf R and havent bothered to go on the VW forum lol.
so heres my question, which intercooler is the most popular? and which one seems to give the best performance?

yea i was looking into that one too

[DarkSideGTI]

Integrated Engineering's intercooler is almost ready as well. Theirs has FDS technology which helps a lot.

[shayan_a4]

why does there have to be so may options hahahahahah

[ModdedEuros]

We run the Unitronic intercooler on our MQB which has really nice quality and performance

Unitronic Intercooler Upgrade Kit (15+ A3/S3, 15+ GTI/Golf)


They also have published a lot of data



Despite the ambient and inlet temperatures being higher, Unitronic’s Intercooler Upgrade Kit provided significantly lower intercooler outlet air temperatures consistently throughout the consecutive pulls, resisting heat soak, unlike the OEM unit.

The two fastest S3's on the AZ official quarter mile list are running HG-Motorsport intercoolers:

Second the APR Notion here. We stock these intercoolers as well.

If you have any questions, please let me know!

Thanks,

I'd recommend reviewing the empirical data published to ensure that your hard earned money is going to result in the best performance possible. Please keep in mind a few things when analyzing published data and/or comparing such:

We performed 20-second duration pulls, to apply high load on the engine, during our empirical data collection. We did this to simulate demanding driving conditions, when an effective and efficient Intercooler Upgrade is most important. We opted against doing "normal" duration pulls, as we didn't feel that it was the best representation of a stress test.

If making a comparison, be sure to compare all the published data, like IC inlet temp's, IC outlet temp's, and keep in mind the ambient temp to keep things relative, but also provide you with empirical evidence on how effective and efficient the intercooler is. Results can vary significantly without factoring in the ambient temp. Also, compare all of the previously listed items throughout the duration of the published data, to provide you with empirical evidence on how resistant the intercooler is to heat-soaking. Factor in what was mentioned above on the testing conditions, as a longer duration pull will increase the chances of heat-soak, providing what we think is the best representation of what our product can do. A shorter duration pull will certainly show some data, but I believe a longer duration run is a better way to show performance of an intercooler in a high stress scenario.

Here's our published data for reference:

Utilizing its 2015 VW GTI for research and development provided Unitronic with a platform in-house to run through the testing. Testing was done on its in-house Dynapack hub dyno, using our standard cooling fans aligned with the front end of the vehicle. The vehicle’s front bumper/fascia was fully affixed for all tests and the appropriate data acquisition tools were used to collect pre- and post-intercooler air temperatures. All data was collected on the same day, starting with the OEM intercooler testing first. Temperature probes were tapped into the inlets and outlets of both the OEM and Unitronic Intercooler core end tanks. Ambient air temperature varied slightly throughout the day between 20-22 degrees Celsius (68-72 degrees Fahrenheit). Testing consisted of 9 consecutive dyno pulls with a 20 second pull and a 15 second cool down period in between runs, with both the OEM and Unitronic Intercoolers to collect inlet and outlet air temperatures to provide data on cooling abilities, efficiency, and resistance to heat soak compared to the OEM unit. Despite the ambient and inlet temperatures being higher, Unitronic’s Intercooler Upgrade Kit provided significantly lower intercooler outlet air temperatures consistently throughout the consecutive pulls, resisting heat soak, unlike the OEM unit.




The graph below shows the Inlet and Outlet Air Temperatures for both the OEM and Unitronic Intercoolers, individually for each of the 9 runs. Once again, despite the higher ambient temp during the Unitronic Intercooler runs, and increased inlet temperatures, Unitronic’s upgrade provided significant reductions in outlet air temperatures resulting in a cooler, denser charge air being ingested by the engine, resulting in increased performance. It’s resistance to heat soak means that the core retains its cooling abilities, even though the most rigorous of conditions.

thanks for the help everyone!!

[ModdedEuros]

hmm not seeing the testing condition data on the intercooler? The Timeslip is not data comparison for intercoolers.

Just curious to see the testing conditions as its important to keep the results of testing relative when comparing otherwise really cannot compare

[DarkSideGTI]

IE provides data on their kits.

The MQB kit is coming very soon.

By condition data, do you mean ambient temperature? If so, that is on the independent IAT log. In terms of timeslip data, if the two fastest S3's are running the same intercooler and out-trapping similar setups by 3-5 mph, there is certainly some relevance there.

No same logging conditions as time between runs for cool down etc...

Are all those cars the same weight? Or are some of the top ones yanking things like passenger heated/electronic seats and other items to make them lighter thus giving them better times in the 1/4? What elevation were all those run done at on all those cars? Same track/driver?

My APR IC has been working great, the car has a more consistent level of power now, less affected by outside weather conditions. So many choices, they all look very close in design. I've had good luck with APR stuff, so that's why I went APR.

[John@Unitronic]

The ambient temperature is definitely relevant to scale the empirical data. It's also important to know the factors during the recording of the data. What type of testing conditions were used? Was it the same vehicle? Was it performed on a dyno or elsewhere? If on a dyno, how long were the pull duration(s) on each? How much cool-down time was taken in between pulls, if multiple pulls were made on each condition? (In some cases, only one pull was performed with each condition, which really isn't much of a comparison, in my opinion.) What were the Intercooler inlet temperatures throughout the run(s) performed? What were the Intercooler outlet temperatures throughout the run(s) that were performed?

As I mentioned above, we performed 20-second duration pulls, which applies high load on the engine which simulates demanding driving conditions when an efficient and effective Intercooler Upgrade is important. We've published IC inlet and IC outlet temp's, along with ambient temp. listed throughout, showing effectiveness and the efficiency of the core, including its resistance to heat-soak even on the latter of the 9 consecutive long duration, high load runs we performed.

We hope folks value this empirical data published when spending their hard-earned money. Here's some feedback a few Clients have posted:

I love my HG intercooler as well. Lots of track passes and IAT stayed near ambient. And PERFECT FITMENT

[dwpaudiS3]

I just had the HG HF installed last month, took car to Vegas from Phx. ran great.

[ModdedEuros]

All that info can be found in the quarter mile list thread:

http://www.audizine.com/forum/showth...er-Mile-Thread

Sweet thanks for the link.

First car on the list removed components to drop weight (heavy passenger seat etc) and 3rd one on the list has no notes of weight reduction. The 4th one is just running an intake and stage 1 with OEM intercooler. Which if stock weight is only .23 slower and that also has a 1.8 60 foot compared to the 1.75 on the 1st spot.

I'm surprised you guys can still type with Uni's nutsack so deep in your throat.

Nah just actually trying to compare data.

For example I can say a car runs faster with ABC shift knob if I want depending how I word it. Relevance of data and conditions is important when comparing data. That's all.

[Auditude2.0T]

Lets see some real world data then. Hit the track and report back.

[ModdedEuros]

The data is there. We are comparing intercoolers. Just waiting to see the rest of the data on the other options on the market. Some HG data is up but missing some pieces. IE def puts out some data with everything they do which is cool.

1/4 mile times posted are not a way to compare as already mentioned. As the comparison was a car running with less weight and a better 60 foot.

Not being a fanboy by any means. Our S3 does not have full Unitronic parts on it for example. Runs a CTS downpipe, Remus catback and Neuspeed Intake. Most of which Unitronic offers and we sell. Just stating the facts. If someone is truly looking to compare the performance of a part, in this case an intercooler you need to compare the empirical data of that part and isolate it so there are not added variables.

There is more to an intercooler than simply cooling. You can make a very dense fin structure that produces great IAT's, but it will also create pressure drop. The downside to this is that you now have to run a higher turbo duty cycle to make the same boost in the manifold. By running a higher duty cycle to make normal stage 2 boost levels, you are decreasing longevity on an already problematic factory turbo.

We post real world results because that is what customers experience. Customers don't buy an intercooler to do 20 back to back pulls on a dyno. They buy an intercooler to run faster times, make more power and see lower IAT's during their typical driving. Our data reflects all these goals. We run everything we sell and don't simply take the manufacturers word for it, but rather perform all our own testing.

We don't need to attack your product, as you seem fit to do to ours, as the results speak for themselves. Until proven otherwise, the fastest S3's are running HG-Motorsport intercoolers. If it didn't perform as advertised, we wouldn't be able to trap almost 117 mph in a positive density altitude.

We're also fortunate to have great customers who have been happy to voice their satisfaction in this thread

[PRGRMMR]

Positive customer feedback and real world results. I know which intercooler I'm getting when I get one ;)

[selp]

In the end.. I am happy with the HG intercooler, and I am sure everyone else is happy with their intercoolers as well. There is no need to argue about data, and who's got the biggest stick.
Are they better than stock? I am sure they are, by plenty.

[WildHareMS]

This is all really funny... :)

I've had my car down the track several times now. And you know what? Its at least 5-10min in between runs. Sure, that's not a lot of time for cooling down hot intercooler...but my IAT's do drop significantly. And that's the stock IC. At the track, I can control when and how hard I run.

I'm much more concerned about street driving. When I'm sitting in stop and go traffic watching my air temp on the P3 gauge reach 150° and then I'm accelerating to get on the highway...that's when I worry. I can only hope the IC performs at those times.

Oh....but then nobody actually tests or publicizes info like that. Lol

Real intercooler data is all I was asking for. Not attacking by any means. We just see so many bad comparisons on the market place across a wide variety of products. ie. People comparing after dyno runs on different cars on different types of dynos

Just was looking for an accurate comparison of cars which does not exist for the products on the market. Only see cars running less weight and better 60 foots running faster 1/4 which regardless of IC or not will produce faster times from those variables alone. To truly look at how these intercoolers are performing you need to be able to isolate the environments for which you are testing them.

[selp]

I will log IAT tonight when I take the car to the 1/4 mile.
Not sure if that will help with data, but at least it will tell me the ability the intercooler has to exchange heat.

[Baggio]

I just ordered the APR intercooler as well as the full APR silicone boost hose kit. Will review after installing it. Next step is downpipe and upgrading from APR Stage 1 ECU/TCU tuning to APR Stage 2.
