Everyone laughed at me when I said I wanted to Ac my intercooler.
I knew I could be done. Luckily I kept everything!
Klasen has been using this for years
@@TurboAcki apparently designed in Australia, where I'm from.
Not many car enthusiasts with Supercars here.
We all usually go the Ls1/2/3/4 route with oversized bolt-on's
@@hulkgqnissanpatrol6121 no problem - A/C cooled intercooler is no new idea :) but may you check youtube for Klasen ;)
Has been around for many years, I had a Killer Chiller system on my E55 and bought the car with the kit installed, this was about 6 years ago.
Works perfectly ike you would expect and nowadays some newer high performance cars have this option from factory.
Of course it can be done, I'm not so sure of the benefits though..
I always thought about this and wonder how it would perform, amazing that you do it.
I too have thought about this, my thinking was the losses from driving the air con compressor wiped out the gains.
Something to add, now that I've watched the video - the other purpose for the interchiller shutoff valve is so you can use the system on a track without the evaporator dripping water on the track. Cutting out the cabin air means you're not pulling moisture out of the air and so there's no water to evacuate. A lot of tracks mandate turning off the a/c (especially in hotter climates).
FI are an excellent business to deal with.
I'm a DIY guy putting an interchiller on my old valiant, working from the ground up as a long term project.
Even though my project is just a 60's resto-mod build and these systems often go on big dollar modified exotics and 7-8sec drag cars, he still wanted to make sure I had the knowledge to optimize my system on the old val and make sure it works as it should.
Before they sent mine out, The owner of the business called and spent about 40mins on the phone with me. He googled pictures of my specific make/model to offer tips on getting maximum airflow to the condenser as well as sizing my AC pump with a high quality unit. He answered any questions I had and told me to call if i run into any issues.
Mine basically paid for itself on the dyno.
Being able to reverse heat-soak and actively control your IAT saves hours of wasted dyno time. You can get a whole weekend's worth of steady state tuning done on a Saturday morning. 👍
I think dodge demon has an ac cooled air for the compressor 🎉 Cool ❄️ thing 👌🏼
Yes it has a small system! I forgot to mention that in the video. I do not know any other car that have this system.
That plate heat exchanger/interchiller is massive 👌 just a brilliant idea to control the AIT's.
I completely agree with the volume amount in the tank/buffer. 20L is a good amount of thermal capacity but say another 20L, That would really help and guarantee the temps too stay low on a hard circuits.
The pdm to control the setup is incredible also. We are really living the dream to the world of tuning cars... anything is possible.
Keep the vids coming 👍
Cool stuff PB, with interchillers there will be condensation inside the intercooler. You will notice this when you cruise at low load for about 20mins then tip in the throttle. Water condensate will be drawn into the engine causing some bad combustion.
With the Motec if you have M1 build write some software to control the solenoid valve so your target intake temp is at about 20c. That way you will have way more reserve cooling capacity (low temp) stored in the chiller tank for high boost.
Since his is a water to air system, and the AC is cooling the water via the heat exchanger, The a/c is isolated from the air charge. If the ac is controlled to keep the water temp at ambient and never lower, the condensation at low load will be the same as without A/C. As long as you don't cool the air lower than ambient temperature, water shouldn't condense. You need a pressure and/or temperature drop below ambient to get condensate. That is never the case after a turbo.
If you put A/C into an air/air system it will condense because the core is much colder than ambient and exposed to air charge directly.
Ideally you would tune the car to turn off the A/C while cruising because it isn't necessary and makes the car more efficient.
@@notsofresh8563if he cools the air below the dew point of the air he will end up with condensate in the intake air. The dew point is a function of amount of water in the ambient air, aka humidity. I deal with this stuff working in engine cal for a OEM
@@AndrewEG That is why I talked about not cooling the air below ambient by controlling the AC with the water temp of intercooler. After the turbo the air is under more pressure and temp than ambient, thus further from dew point. As long as the water in the intercooler is above dew point no condensation will occur(rarely is dew point above ambient)
Granted the core may be colder but in a water/air setup it is immersed in the intercooler water, not the air. The water temp is the one that matters. as it is what interacts with the air.
Condensation in an air/air setup is way harder to control because the ac core is in the air and way below dew point.
@@AndrewEG In addition, using the ecu to turn off the ac in light load/cruising situations both prevents your pooling condensate problem but also reduces parasitic loss at low load increasing fuel efficiency without sacrificing high load power.
Thanks for input. So far i have not noticed any problem with low load driving. For the solenoid i can write a control logic in the PDM.
But my plan is to control the temp to not be too cold during normal driving with water pump speed. Right now it is on full speed all the time.
Interesting. Are you ‘taking’ horse power away from the engine to run the AC compressor to cool the refrigerant which balances out with the power gain you get from lower intake temps? Or is the idea that you use the AC power before the drag strip to ‘charge’ the refrigerant and then it helps in the drag?
I'm sure he said the AC compressor doesn't run on full throttle, so it might struggle on a curcuit.
An interesting idea though on the HP gain from cooler intakes off setting the draw from the compressor.
The car cuts the AC when you go to full throttle? Logging data on a race tract would be interesting. If you shunt the AC control and run the compressor full time, it would also be quite interesting to measure how much the AC costs in raw power vs how much you gain from the lower temp
all vehicles cut the compressor when at WOT. weather you know it or not. but yeah it would be interesting to find that out.
Was thinking the same. I would think that this is something that could be disabled in the cars system.
@@Timoastra definitely yes, its operation can be changed by programming with changing the threshold values for when ac is dropped off.
Cool system 😉 sorry for the bad joke 🤣 Nice video 👍
How are things going with this stolen R8? What is the reason the Swedish police do not show up at your house and confiscate the car?. Such a tragic thing to happen when you buy a car at a serious dealership. Whats the current status on your work with authorities about the car?
Yeah, what about it ?
Did you watch the video? He talked it through.
By Swedish law he probably owns it until the insurance company makes their case in Sweden (if they do, thinking they can win). He just cannot drive it on the road without the paperwork of course.
Looks like it going pretty with the stolen R8, he seems very happy..😅
Great video. Im gonna put this in my RS3 thanx wasnt sure I could use it with a Turbo car but I guess I just have to go W2A air now. I already have one in my Redeye well sorta cause it comes with a factory one but I did upgrade to the stage #2 for my redeye and I also put one in my Trackhawk while using the Cortez setup that gives u more cooling volume.
my next supercharged car definitely needs an interchiller. i see them on hellcats and stuff.
Dealing with Insurance companies & their wonderful staff is the pits. The girls club is in full force it seems. Its part of the reason why I will NEVER even touch Progressive insurance. Same thing with Geico, and that was FAR worse! They cancelled my plan when I was in the Military when I called to ask if I needed to buy Extra Insurance if I wanted to do Pizza Delivery on the weekends.
I called from my office with my "Boss" and they cancelled me saying that they heard a Pizza joint???
After that? I keep enough funds to cover the state Minimums since Insurance is such a joke.
BTW? I had to have my command / X.O. , call Geico and straighten things out. I switched to USAA shortly afterwards.
Amazing I was planning to do this and now I am more convinced, being an engineer I know it will add better cooling to the cylinder after a pull and will minimise risk of overheating the rings and cylinder walls, I do believe that heat is what damage engines not anything else
Heeey here from Odense Denmark ..🇩🇰🇩🇰🇩🇰🇩🇰🇩🇰..
Mutch Support..💪🏼💪🏼..
Do you remember Kjelle turbo? He drove a Mercedes on mantorp witt an insane cooling setup. Beställde föressten grejer av dej i dag :)
Hi!!! I’m living in Montreal, how can help you? On peut échanger en français aussi.
How much hose power AC compressor will take from the engine?
Ok i will bear in mind about condensation when driving my AC intercooled V10 on the dragstrip ...
Always look forward to your content ☺️
It would be interesting to see how much Kw the AC pump consumes.
So this system is able to keep up with cooling this on a track (non drag racing)?
If you want even more power, cool your fuel too. Make fuel lines go past the cold water.
Why has no one thought of this? Not just power but knock prevention, i know sometimes they run a little fuel after lift off to cool the engine, if that fuel was just above freezing the cooling effect would be enourmous not to mention coupled with -5c IATs
I am in Australia and have never seen or heard of this company before now, pity they don't direct more advertising toward us here in Australia.
im always getting facebook ads for them, its quite annoying actually but seems like a good product none the less
@@joshtong7332 I am not on FB and I guess some others aren't either, sad really, they are losing out on sales.
I was just thinking about this laying in bed
Can you register the Audi in Sweden now ?
How high does the high pressure get with this setup with the AC, if you have checked it in just curious im a working as a HVAC tech🙂?
Shouldn't it be the same? It doesn't have a pump or? Or did I miss something ?
Hey,Peter,this idea is not so good, from engineered aspect!! Lower intake during the cold weather,means worse fuel homolugisation,low power,high emisions an quick lash the bore!!! This is very old idea...you can instal WMI with better results!! And you push you AC compressor to work.with 100 % pwm control valve...no godd idea again!! Think abot it!?🙂
dumb question. Why use water when its going negative degrees? do you get small form internal crystalistion of ice, or Ice forming in the main header tank? My little brain assumes a refridgerant with a greater operating liquid temp range would be better. like R32 or R410A. However maybe the flowing water is fine? Would love to put this in my CLS63 but its a dialy driven car which comes from factory with water to air. Thanks
Do you still have a/c for the car ?
I've been looking at these for my build, glad to see you had the same thought!
Interesting...I have a 1994 Maserati Ghibli II, and it uses a double-walled pipe to enclose a section of the fuel return line with the a/c refrigerant. I doubt my a/c is good enough to cool much more though:)
i want to try this
Dodge Demon has about same system called SRT Power Chiller.
Ta och prata med Daily driven exotics 😅🫣
Do you run distilled water? Or mix coolant and distilled water? Cool system!
i miss volvoghini 👍
Wonder why manufacturers havnt caught onto this
worth to mention. Trackhawk also uses the ac for cooling.
I believe the v8 Ford GT, as well as the McLaren GT use AC Interchillers
Innovative excellence as always, thanks!
Very interesting! Best of luck with the Insurance company.
How's the power tradeoff with an interchiller system? Lost power from the compressor friction compared to the gain from the denser/colder air.
Even if they cancel each other out you don't have to bother refilling an ice tank, and you have gained luggage space. I think it's a win.
since the A/C only is active on partial thottle you will have all the power when you make a pass. like all A7C systems it shuts down on a certain rpm to not get over pressurized when going pedal to the metal.
On big engines with lots of power it's a definite positive trade-off. 10 to 15% added power over the entire Rev range. (Result of my 5 minute research. 🤓)
Think of it as a function of the effiency of a heatpump. You could probably achieve a lot of the performance benefit in other ways, but you would be having much larger intercooler or other stuff that could for example increase the frontal areat. Etc.
This is so cool, I'm a refrigerant tech. And gear head. Though of this for so long!
Is that the type of system that had a v8 driver banned from Dakar years ago
this is a great idea, probably saves some weight not needing a seperate intercooler for intake air cooling, and the temps are ice cold too
Just searched for this after I had the idea so cool to see it at work
Thx for a great video I found your other channel I don’t speak Swedish but I enjoyed it anyway I had a 1984 Volvo wagon that I used for a work car it was great such a solid car
Great video, where did you install it mate?
I wonder if this type of system could be extended to provide cooling to the fuel too? I have a car that suffers with high fuel temps because the tank is too close to the engine and there is no way to relocate it or add more shielding
I installed a system like this on a mustang well over a decade ago. The customer had to replace the a/c system in its entirety. It would kill the compressor with heat soak.
The system I installed was in series with the ac system
When are you doing an update on the volvo?
👍🥶👍
Kind of like what every sufficiently designed EV does - in their case just to cool the liquid cooling system.
Oh yeah, you talked about it in the video :D
Sjukt effektivt system 😲
Wow brilliant Peter. I had this idea for a long time also but not building cars at the moment. Actually I want to ask why you use AC-water-air transfer, why not just AC-air directly? Seems complicated and extra weight. Only reason I see maybe is that you cool 'extra' water in the tank and when you accelerate water is slow to heat up Vs AC would heat soak faster.
I am curious to hear what your experience is because I really like this. Super cool sir and loads of useful info.
Tack!
That design turns the engine into a very effective bomb if it fails... use with caution. Also it is more prone to heat soak
@@r2d2fish38 bomb how please? Assuming a refrigerant leak into the engine?
Cool idea
You are always f... awesome
I have been thinking this long time and now i'm 100% sure that it will work!! Hell yeah! 🤘🤘 Does this system work with coolant also or just water? So it can be used winter time also 🤔
Also would be nice to see dyno pulls this system compared to air/air cooler 🤔
You can use coolant to but the ac shuts down when it is to cold outside
Nice video
Whaat? Cool idea
Do you still only have 2nd and 4th gear or did you fix that? What caused it?
It was difference in gearing. The gearbox i did put in had different gearing and the TCU was not happy with that.
Very *cool* indeed. 🌬️❄️
Great update 👍
Awesome content!
nice
Would it be able to be used in parallel with the cabins A/C and still get very cool air in the cabin?
Thinking of using it for efficiency gains during cruise condition for example where you need both. Thinking during double use the condenser becomes very heavily loaded and could become a limiting factor.
Du har inte ritat upp någon modell / diagram över hur det här systemet är draget? vore kul o se.
Det är med ett enklare schema i videon, finns även på fiinterchiller.com
@@PeterBjorck länken fungerar inte :)
tog bort "fi", fungerar.
You can always add more thermal volume to the intercooler by adding a bigger header tank if you find that with more boost the temps creep up at the end of the run 👍
Mekaniskt geni!!!
The Dodge Challenger SRT Demon had this back in 2018 didn't it?
yup
Yes! I forgot to mention that in the video.
I’ve heard these systems fail and ruin motors… I chose to go methanol. I hope the very best for you!
I run methanol and still need better cooling.
It'll damage an engine if you ignore all the safety lights/alarms and temperature gauges...
How can it cause damage to the engine its just a normal watertoair intercooler with interchiller
@@Slatteby I think they might mean overheating?
It was the ONLY thing I could think of...
@@Slatteby the way it was explain to me was if it quits there’s no indicator that it is not cooling the air and the engine doesn’t know to pull timing out fast enough to save itself. I wanted to put a inner chiller on my ZL1 and I had too many opinions, professional, and not talk me out of it because of this
@@The_Drive_Inside This car has intake air temp sensors so the ECU knows when to pull timing or adjust fuel. Factory ECUs frequently don't use these or if they do the circuitry is very basic and tuning may not be an option or is locked out. Safeties for when air temps spike are available in most aftermarket ECUs
Is the horsepower gained more than the horsepower "stolen" because of running the AC compressor and other components needed? If you gain more HP how much % wise?
Why would you use it if it takes more than gives?
@@jonnenne One reason would be the positive effects of lower IAT despite constant net heavier load in certain niche applications.
Of course not, fysics still apply... 😉🤓
This product is awesome and seeing a video from you on this; it's the perfect confirmation
How much weight did you add?
What are the Dyno results?
Could be made to be an independent system by using a standalone electric AC compressor instead of engine driven that cuts out with high throttle inputs.
could maybe try to harvest the ac system out of a prius. they're electric powered instead of belt driven so work independent of the engine
@@kasuraga these Pirus AC compressors run on 230-300V three phase high voltage and need a high voltage inverter to operate them. if the car has an AC system, there is no need. The cooling power is anyhow insufficient for sustained WOT. It is only good on the drag streep or a pull or two on the streets.
Why the hell would you need it its freezing in switzerland anyway, unless you in say adesrt of UAE then fair enough? 🦘🦘👍👍
Also i thought of this idea way back in the early 1980's, shame i did not get a patent on the way it works etc. 🦘🦘👍👍
