On my Type R I've changed the radiator, the radiator Hoses, the intercooler, intercooler piping, water wetter etc. The most important cooling mod I did was change the front grill to one that's at least 3 times more open. It made a massive difference. People change the Rad and not the grill. You won't get a single benefit if you can't get air to it.
I've had a grill sitting on my workbench for a few months, I have to get on this. Curious...did you do a vented hood as well?
@@Boostd4 I haven't. Definitely thinking about it but so far everything else I've done has helped a good amount. Doing the Turbo and Titanium Downpipe first then revisit more cooling if needed. What grill did you buy?
@@thinkforyourself5672 I just picked up one of the Varis type clones. It's the more square opening, but it's huge. I've been hearing more about this being one of the more important mods to help with cooling...more air. It still blows my mind that Honda didn't put an oil cooler on this car.
That was nice information I didn't even know about. 👍 Great content FlyG!
Glad you enjoyed! More coming, as usual
Great video, learned a lot! I have not had issues with my '18 FK8 yet, but there are times when it feels stronger than others. I actually had more heatsoak issues with SI that preceded it, which sometimes was very laggy.
Yep, it's all about heatsoak
I'm patiently awaiting the arrival of my fk8. Still another 6 weeks or so to go. My excitement has me going through almost every fk8 video on youtube. This is by far one of the most in depth i've seen. I'm no mechanic, but your use of diagrams makes it pretty easy to understand what you are explaining. Lot's of effort was clearly put into this video. Awesome work man, look forward to see what else you have to post.
Thanks for the shout out! I try to be as informative as possible in all of my videos. Sometimes people think it's too in depth, or too informative, and switch off to watch a ferrari get twin turbo setup to spit flames and a "sick" car wrap.... lol. You'll love your Type R
Great video Tigre! Great information.
Much appreciated
Great discussion! It's not a drag car, or a true track ready racer I guess. It is a very capable, and entertaining street machine. Exactly why I love mine. (if I don't consider the horrible sound system).
Keep them coming bro👍🏽👍🏽👍🏽
More to come!
I'm thinking alot of research went into before making this video. Well done!
Glad it was helpful! A lot of research goes into me owning all of my cars, I know the ins and outs before I buy them, and if I am going to mod them I dive even deeper!
Very informative and factual explanation. Just came from a ZL1 that had tons of coolers. The setup is very similar to my 2020 Supra which did not overheat at the track in the summer even though it had the same water cooled integrated exhaust manifold (which is great for warming up oil/water on a cold day on the street however!). The 2 big differences is the Supra has it's turbo down low and off to the side so it easily dissipates heat, and the bigger one is that it had 3 more coolant radiators than the Type R. Yes 3. Had 2 big radiators in the traditional location, and 2 aux on each side where the CTR has room but has block off plates. Also has rotary valve thermostat to control high and low temp circuits and used an oil to water cooler to keep oil temps in check, used a water to air intercooler, and even used coolant for the AC condenser unit so there isn't even an AC condenser or air to air intercooler in front of the radiator! Great system actually. Maybe the 11th gen Type R will come track ready from Honda with cooling?
Awesome video.
It seems that the Type R has similar overheating woes as my MK3 RS. The coolant is used to cool many things and gets routed to different components (differentials front + rear on my car as well as the block for emissions thingys like you explained). Take a look at what the ECU determines what is "safe" and where it takes its measurements for temp in order to pull timing. My car relies on a estimated temp since it lacks sensors in all of the points of cooling used by the coolant. So in the end you can add all the measures for improved or efficient cooling, yet the ECU could still be pulling timing due to its programmed safe tolerances that could be too conservative to push it.
Good luck on your journey to cooler temps and faster laps!
Thanks! yea these hot hatches, being based off economy cars, definitely have limitations
Very good points Elias.Why don't you open all the fake vents to push more air to the radiator and also upgrade for a bigger radiator.I don't know if you wrap up the intake pipe will help a little bit .Also could help a vented hood.You do greate work ,keep going.Im sure there are many possibility to more cooling but is importat to start with the most simple ones and natural and of course not expensive.
yep, I'm starting with the simple things and a few key upgrades as well. Eventually, we'll see if we need to add meth injection as well
U would probably love an intercooled centrifugal supercharger kit on the s2k.
Need to mod the bodywork and front frame on the fk type R in order to fit all the extra cooling goodies on there. A lot of research and work is required at this point.
An aftermarket vented hood might help a lot with cooling. Plus there are a lot of thermal blankets and shields for turbo systems available to help engine bay temps.
Turbocharged cars' weakness has always been heat. However that weakness doesnt really show untill u actually push the car very hard such as in track conditions as you mentioned in the start of the video. Your average joe driving an FK8 and just drag racing will probably never have this problem
Who the hell drag races a type R? Maybe you're referring to casual pulls.
Great point! Those that do drag race (and I do have something to say about drag racing FWD cars) can also get a lot of heat soak, but the normal Type R driver won't usually feel too much of a difference, unless sitting in traffic in the middle of summer
I wouldn't call it a weakness but rather a known issue to be aware of. There are many manufacturers that don't have temperature control issues after track abuse. Honda got it wrong this time around.
The civic type R might need a v-6 upgrade. I have read the new S2000 will be a v-6 engine/
Turbos dont last. Thats a fact.
If I'm correct there's a transmission cooler and a oil cooler using the engine coolant to cool the fluids.
Love the video bro
Appreciate it!
Welcome back bro República Dominicana Presente!!!
Quisqueyano!
@@FlyinGato the Dominican community in U.S.A. are so proud by you!!!
On the performance front, the 2020 Honda Civic Type R's grille opening is now 13 percent bigger, which Honda claims it allows the engine to run 18 degrees Fahrenheit cooler on the track. This is a welcome change considering the overheating issues early cars had when taken to track days. Compensating for the decrease in downforce brought on by this new grille, the car's front splitter has also been reworked.
Awesome detail explanation. Kudos! I got a doubt, is it the same issue with fk2r too? fk2r and fk8r have the exact same engine, does it have the same issue too?
FK2 does have the same issue, unfortunately
The new one has taken these problems into account and I believe added way better airflow and ducting too the mix. Rumour also are there is a better rad and cooler also but I cannot deny or confirm that 👍
yea the grill is a bit bigger, but if you noticed, my grill is entirely mesh to let in more air. I'd like to see what else they did to try and mitigate the heat
FlyinGato I think with that stuff we’ll have to wait, but one things for sure if Honda knows there a minor problem the’ll fix it that’s for sure and make what’s already good better.
Cool it’s also got a shorter throw too and so more new bits on it. Making an already great car greater 👍
The exhaust gas is also used to heat up the car quicker for optimum running tem, and cool the exhaust gas to prolong the longevity of the cats. Type r is a great car, but it’s still a civic so a lot need to be compromised in order for it to run so fast.
Hi. I am curious where you got your information about the MAF sensor location and the inability to relocate it?
Water cooling is necessary on the exhaust manifold to control NOx, since high exhaust temperatures create NOx.
Yep, spot on, but I don't like it
9:33 I agree with that no intercooler no oil, cooler, no transmission, fake vents but S2000 it's still a good legened car while FK8 super futuristic look but we will see if it last that long !
I had one overheating issue since I got the car. It was extremely warm, 37 degrees celsius. I was close to top speed for several minutes, keeping it mostly full throttle doing 260-275 kph when I noticed the coolant temperature climbing towards the top. It was warm and under max load but I've never experienced this with any of my previous cars.
Were you tuned?
@@TR1_93 No, it's a stock engine. The water temperature always starts going up at high speed and high throttle. It's interesting because on the track and under heavy acceleration through the corners no problem.
I am about to buy one from Germany. And I live in the Middle East. Saudi Arabia . The temperature is very high here. And when I saw the video, I hesitated to buy. Is the car temperature very high during normal driving times and using the air conditioner for long distances? Is there any advice you can give me or what should I do? Knowing that I intend to change the air intake and change the programming when I have one.
Maybe a hoodspacer an option? It raises the hood a little so hot air can escape much faster.
that's not a bad idea, I'd have to research to see if it actually works
@@FlyinGato good luck mate!
I hope Honda guy engineer see’s this problem and address it and fix it🥺
Couldn't help but chuckle at Honda loving simplicity in their engine bay engineering. That might have been the case 20 years ago, but the decision to incorporate turbos into everything changes that model up quite a bit. I know that folks love their CTRs and I'd never deny owners their thrills, but I sure wish that Honda had stuck with their NA, high-revving power plants. It really is ok to have 'just' around 200hp in a lighter vehicle.
It would be a dream is Honda made a newer high revving engine, like Kerim said, a high revving inline 6 would be a dream come true, but even a high revving 4 banger with 260-280 HP would be beast. The lack of extra coolers can be explained by Honda's drive towards simplicity
Nice explanation.
Glad you liked it
love your track section of the video and wanted to know if you ever caught up with that yellow integra in front of you :)
I did, and then I crashed, so he won in the end lol
@@FlyinGato ah got it, that's what's led to the crash, but glad you are all good and racing again. keep up the awesome work with the channel, i find it very informative especially about the technical stuff which is what i look for!!!
Glad you've been enjoying it
The exhaust manifold is basically integrated into the head now. The “block” and the “head” are two different components.
Yep, I hope I was clear on this in the video.
yo what size of wheel size are you using for winter?
The lack of any additional cooling does in fact keep it from being a track car. Racing is about details and complications and not simplification and sorry but that is what it is. BTW is a turbo a complication??? I never see any leak problems on the Camaro forum although I can attest you can get a rock thru one of them. Any SS or above Camaro or even a Standard Vette has additional radiators usually two. Then an oil cooler ,then aux trans coolers and often a rear diff cooler. A better design might have been to put the exhaust and turbo in the back of the engine and intake in the front and keep that heat back there. That is what Audi\VW is doing for FWD vehicles. Changes the plumbing for the intake quite a bit and I suppose trying to push the boost over a longer distance may add turbo lag.
Sounds like some engineering issues. Great explanation. I think honda figure most owners will only do spirited driving for a short period of time, not tracking it all day long. Very nice s2000 btw.
The stock intercooler is also waaaay to small. Replacing it soon...
yep, that'll help especially when you're running more power than stock
I put a hood spacer on mine!! That shit works!!
I have to look into doing that, may be easier than cutting holes in the hood
CAT OUT.
If I get a CTR, that will be my first mod. ;)
p.s. agreed on the S2K ^^
Also glad to see you healthy :)
glad you're healthy too! And trust me, the downpipe (catless) is coming very soon
@@FlyinGato thanks man !
and... awesome ^^
can't wait to HEAR your feedback ;)
any idea if the radiator from the 2020 Civic type-r would fit the 2017 through 2019 model years the part numbers are different and from what I hear the 2020 has a bigger radiator
it's only slightly bigger. I'm getting the real upgraded radiator soon. Full video of when I get it and why I like it so much coming soon
Gato, I went with the eBay grill for eventual track time. How MUCH does it help? Like, will you be able to tell a measured difference between the stock and eBay?
it helps a significant amount. Tom O'Gorman, Type R race car driver for Factory Honda Racing, told me 2 years ago to get one
@@FlyinGato I know the 2020 model comes with more open grille, like the ebay grille. Between the grille and a new intercooler (let's say PRL), how much of a difference would you say there is for cooling? No comparison?
It overheats if you track and abuse the crap out of it especially during the summer
The 2020 Civic Type R has this fixed apparently, by having a slightly larger front grill. Should we believe them? 🤔
Just out of curiosity have you tried turning the cooling fans at lower temps in your tuning platform? (Ktuner/Hondata) I’m not sure which you have.
I have KTUNER, and trust me, at the track, the fans are on full blast
FlyinGato what temp do you have the fans turning on at? I have mine set at 180 for the first, 190 for the second and the 3 I left at the setting that was on the tune.
The way to avoid heat soak is better engine bay ducting and or a higher capacity radiator then?
Yep, that's the way, and to remove as many heat components from the hood, as well as heat wrapping
@@FlyinGato so you are saying -Do not use any Heat Wrap ?
You should use heat wrap
So what are some things you you would suggest to remedy these issues on the type r?
I've covered it in a few other videos, but a lot of bolt ons, including downpipe, radiator, hood vents, etc...
So even if the heat issue of the Type R can be tolerated, there will be no "room" for aftermarket engine tuning, is that right?
there is some, but there is a limit. If you're trying to get anything above around 380-400 HP/Tq, you're going to be spending a LOT of money on engine parts/tunes etc... and your heat problem will be terrible
Hi,
Very informative video.
My FK2 engine bay is even tighter than FK8 one, it must overheat quickly ^^
Also on track usage on my FK2 I didn't notice that the water temperature go high, but I did notice that the oil temperature yes. I also notice that the engine seems to loose power after some laps
yep, that'll be the biggest thing, the ECU will pull timing significantly and reduce power significantly as well
Thoughts of the 2021 limited edition?
I think the limited edition is great, it adds a few things most Type R owners wanted to see stock on their FK8s. I may make a short video about it. Thanks!
Most definitely @flyingato one big thing I’ve realized is the vents in the front actually have a purpose instead of cosmetics. I’m looking into buying one when they come out 600 are coming to the US so it’s gonna be a hard find.
How many minutes does it take to over heat, and in what kind of temperature?
Also how fast or slow of a track? Faster tracks won't have this problem as much as slower tracks
It all depends on ambient temp, how much extra power you're tuned to, and how much WOT you're doing. Slower tracks may actually have less of an issue, as long straights send a TON of heat into the cooling system, because you're WOT and full boost for quite a long time.
@FlyinGato my time attack series runs on 2 tracks mostly that the lap times are around 1:20.00 to 1:38:00.00 lap times. And sessions are 4-5 laps maximum. So the longest amount of time I'd be pushing the car is 7 to 8 minutes at a time.
From what I gather most issues are coming from people who try and run 15 minutes or more at a time.
A common mistake - modify the heck out of the cooling system of a car and expect overheating to disappear. A very simple solution is to cut the bonnet to allow hot air after radiator to exit the engine bay. Cooling is all about extracting as much hot air in the engine bay as possible.
If you have the availability you should do a 2020 FK8 comparison with the 17-19. The ups and down.
as soon as I can get my hands on one, I will. I was supposed to go to the NY auto show press days and do this, but couldn't due to the current.... situation
2020 model have a exhaust hole under the hood .
I'll have to see that
Very observant 👍👍
Thanks a lot
Radiator fluid? You mean, coolant? 2:11
Then the problem is its cooling capacity
Isn't that the norm for "performance oriented" turbocharged cars? I own a ZC33S and everytime I run it hard for extended periods the oil and water/ coolant temps raise a lot (too much) so you just drive like a granny for a while and it goes back to normal temps. I'm sure most turbo *factory* cars are similar.
yea, heat is always problem, just wish Honda didn't use coolant to cool down the exhaust
first you didn't have bigger radiator. those 2017 -2019 ctr grill is blocking air flow.. buy the 2020 -2021 front grill
I've built up my Type R recently, radiator and grill have been changed
the ek9 civic type r and the dc2 integra type r are the best hondas ever produced. you probably have never driven either. the s2000 in third or maybe even fourth after the eg.
is decat useful?
Very! A downpipe is super useful on these cars
Yeah, it needs an improved cooling system, otherwise it's a great car none the less
for sure, and it only has issues on hard track days
FlyinGato does anyone offer a larger radiator option?
Yessir, Koyo, I’ll be installing one soon
But would a larger rad resolve the overheating issue? Last I looked into this issue, I didn’t think a larger radiator was a solution?
The 2020 refresh I believe has a bigger radiator, thicker one so it might running cooler for longer, but not expecting it to not overheat. The turbo generates too much heat and this is a problem for most turbo 4s,WRX, Golf R and STI all have the problem and ended up cutting timing. I just wish the N/A days come back where I can run my S2000 around the same track on the same condition for longer period of time
The Type R does have a transmission cooler 😎
Could you not just take out the fake vents and make your own vents? And install something there if there is space
an oil cooler is what people do, but that isn't enough
That s2000 tho that's wicked it's not better tham my ep3 tho joke yes it is, 😍🤣🤣
haha! I love EP3s, I made a video of one on my channel
@@FlyinGato can u send a link bro look for it but no joy you got some good videos tho I need to get to a track 👍
Can you run it without a hood on the track and would that help overheating?
it's usually against regulation, and not sure if the aero of the car would be helped by that, necessarily
FlyinGato ah, I see. Maybe an aftermarket hood with additional vents would help overheating.
So much corrosion 😱😭
lol yeah i don't think he gives a shit 😂
meh, it's just dirty. Wait til I get it on a few race tracks ;)
An oil cooler should solve the problem
it will certainly help
@@FlyinGato im not super versed in FK8s, but it's possible it might not do enough to keep temps down as long as you would want. The RS (my car) has similar problems that couldn't be resolved with an oil cooler, no matter where you put it. People have tried the foglight area as a dedicated area, directly in front with direct cooling to the oil cooler, deflectors etc... This is a Honda, think simple. Start with the radiator, maybe even go beyond high capacity, and look for a triple pass. A radiator alone gave me more laps with out cool down inbetween.
This guy is just talking out of his ass never had a problem w the type R how hard you push it dude wtf
What? If you haven't gotten your R hot enough to feel a huge loss of power, you're not living

#1. Because it’s a Civic
#2. Because Honda isn’t a company that makes real sports cars besides the S2000.
#3. Because 99.9% of this cars owners can’t drive properly.
Yet a none racing car does better than a Vw Golf R in the Nurburgring
Huh? How old are you? Heard about NSX, F1 engine, Ayrton Senna, LOL!
