Iroz Motorsports RS3 Intercooler

[brad65ford]

Just arrived Thread titled for only an RS3 at the moment believe Iroz will have the TTRS version shortly. Already have Iroz's Dp's install last week and excited to get some cooler intake temps. Ordered a few weeks ago to get on the list for building one of these bad boys since these are small run custom parts. Quality looks great, surprised to see CNC'd ends, that a lot of machining! From the data they shared it seems like one will acheive pretty impressive gains with intake temps or not be robbed once heat comes into play especially when adding more boost (tune coming next). Where we live down hear in fL we need as much help as possible its hot!!! Trying to get this intercooler installed this week will report back on install. So far from what I gather there is no instruction other then time and hope its a direct replacement fitment. Time will tell, if anyone has any suggestions or inside prior doing the job please feel free to share. Thanks!

Product how it arrived today. Notice the black painted front face, this will match OEM look and not stand out and be to ricey

Wow man, you're on fire with these mods! :P Can't wait to hear your impressions!

LOL thanks, I've had so many cars and modded the crap out of them but never documented swat felt like changing it up. BTW see you're in FL too, hoping this helps with the FL summer heat. I've felt a different already in performance with the RS3 on different temp days.

i sense another video in the making lol

I see a lot of people talking about intercoolers with this car, is the stock one really that inefficient? because the stock one looks pretty beefy.

Yep, i've already felt the effects of heat soak here in FL, i'll be definitely getting an intercooler as well! I wish I wasn't so far from where you are so I can hear your RS3 in person :P You got a black front intercooler.. but their pictures on Iroz show it's all silver.. is that an option? The stealth look is nice too.

[brad65ford]

Agree, shame your way north from me. They called the day before they were shipping it to me asked if it wanted it black told them i really didn't care either way.

[speeddemon69]

If you get some pictures showing the stock intercooler vs the IROZ intercooler please do post. Thanks!

Very nice grabs Bradford im really looking forward to your thoughts on the products. Quality choices so far IMO. IC looks very nice!!!

you should of just went ahead and got their new hybrid turbo to pair with it ;)

**EDIT: i think this might be for PFL version 2.5 but it just showed up in the FL 2.5 section of their site so i was a bit confused

That was the MK2 TTRS. For the MK3 TTRS and RS3 FL Iroz has a development hybrid using Xona internals and I am thinking around 580whp+. We will put one on my MK3 TTRS soon

thanks for the clarification... and ~580whp on hybrid is pretty badass!

Oooohhhh looking so purdy! Stock one is not that bad was expecting a smaller plastic one lol. Thanks for the pic!

About double the surface area on the aftermarket.. I was surprised to see how large the factory one is too.. don't think it's an immediate type of upgrade though tbh.

I can’t run stage 2 software on my car with the stock Intercooler. After a 1/4 mile run My IAT’s run about 40 degrees celsius above Hank’s RS3 with this Intercooler. Heal soak comes on quickly without this.

I want a shiny aluminium one with "IROZ" stenciled on it

That is how they come; the black paint is optional

What is the core volume on the stock and on the iroz?

I stand corrected!

[shivaswrath]

Stock looks good...for stock power.

I'd say even for stage 1 power too

I can confirm stock Intercooler is weak for even Stage 1 power

Do you still recommend the Iroz inter cooler? I’m between the forge ic and Iroz IC... My ultimate goal is Stage 2 93oct... I’m in South Texas, it’s HOT!

I recommend it, dyno runs were 70 seconds apart and I made almost the exact same power. No heat soak here.

What other mods do you have? What fuel was used?

[arrrrrs4]

Downpipe and intercooler with 93oct tune. Car is now on ethanol but I haven't re-dynoed.

I don't see power gains on the dyno but I do see that the power and torque is arriving a bit sooner(verticals bars/reading) further to the left(power sooner). Do you have the whole picture of the dynograph?

This picture is just to show how quickly the runs were back to back and the consistency of the power made.

[awdpwr11]

I appreciated the feedback. Ill go ahead and pull the trigger on it. I was worried It was too big for my stage 1+ software.

I'm just curious, why do you love yours if you saw a huge degradation of power with it on the dyno with both APR and Unitronic software?

[2017AudiRS3]

The FMIC is designed for real world driving not a hot 100+ dyno. On the streets when I run my friends ttrs you should see how much of a difference it makes.

This is good news. I was worried the stock crash bar blocked to much of the intercooler. Did you modify your crash bar at all? How much of the intercooler is stuck behind the crash bar?

[comingabriel]

I was really considering IROZ IC, but then this came up. However, I am NOT feeling the crash bar size reduction!

Almost perfect, can't wait for Unitronic's version, but I need an IC now, yep, all of a sudden and a DP with staight midpipes, for E85 goodness.





My question now is, ok, they got rid of the crash bar from covering the IC (good idea and safe?).
But, what about the grill section that still covers that part of the IC?
NM, saw it is a seperate piece, and for the 1st time saw the vents to DSG coolers are both open, could have swore they were closed, and was like why??!! :losingit:

[awdpwr11]

I decided on the Forge IC myself. I don’t like the idea of half the IC being behind the crash bar. Makes no sence to me

[URHank]

If the heat exchanger has to be seen to be effective, virtually every mid engine car, every rear engine car, and a ton of front engine cars are majorly doing it wrong. Furthermore, how is the radiator and AC condenser even remotely effective with the crash support in place? Last, how does the air scoop up top get fresh air to the turbo? I can't see it either if I am looking at the front of the car.

Some reflective thinking to help people ponder how high pressure zones work if the heat exchanger is baffled to force the air through the core at speed.

Cheers

[silvino]

That's a problem these days in various parts of life. It's a struggle for people to think for themselves as they follow the latest hype. =/

Love my IROZ IC still ;).
