The problem is I don't have room for an extra fan in the front, maybe a baby 8" fan... The intercooler is right in front of the radiator and it covers the lower 1/3 of the radiator... So the option of a second fan in front of the radiator is out...

 

It also depends on your elevation. I'm currently @ 3500ft
making the effective boiling temp 205 degrees.

the water wetter probably helps a bit too.
The thermostat opens @ 180-190 degrees for most hondas but it's not unusual to hit 220 degrees underhood.

 

The first thing I would recommend to give more clearance would be to change the hose on your turbo inlet to something along the lines of this:

After you have more clearance you could also block off that vaccum port which would allow you to have more room to cover more surface area with that fan.

With the additional clearance from that intake hose I posted you could put a fan of similar size that you currently have with a bigger fan motor with higher cfm.

The fact that you no air pulling through that one side of the radiator is not good considering that not only is that side closest to the radiating heat from your turbo and manifold. You could consider putting a piece of **** metal on the right front side of the radiator to direct air into that part of the radiator

I hope I helped.

 

Yes i do run it. When i installed my darton sleeves, they recommended it so the sleeves do not rust away (normal people use tap water). This stuff is waterless lifetime coolant. i paid about $30 a bottle. BEST STUFF EVER! It does not matter how hard/cruise/boost i drive my car. my temp gauge NEVER movers. I do however have a wrapped d/p and a turbo blanket to help with radiant heat. This stuff is very thick for coolant. reminds me of 0w20 oil?? You MUST flush your system out a couple times, then you just poor it straight in the tank. bleed and done

 

this explains the heat issues.....see if you can find a slim enough fan or small enough fan to get one wired onto the front of the radiator.

 

I agree lack of air flow is an issue, but right now it seems that building an aluminium or stainless air duct to direct air to the radiator is the best idea due to space... And even building a stainless barrier to block the heat from the header from heat saturating the left side of the radiator...

I think the header wrap will have a large impact on reducing the amount of radiant heat being pushed over to the radiator... But anyways I'll put in a temp gauge this weekend and let you guys know once the air temps warm back up...

As for the coolant, I think the first thing I will try is a 30/70 ratio of coolant/water and when it's warmer out I'll look into the Evan's waterless coolant!

 

I'm at 1100. I see significant drops, especially in the bikes. Thats where it really shines through the most... Especially when you're raping a 187rwhp liter bike around barber and road atlanta.

I normally use a lower temp fan switch as well as a 180 thermostat. Assuming everything else in the system is in working order and its properly blew, there should be 0 cooling issues.

I wish we could discover/create something like water wetter but with freeze protection. Glycol is good for everyone else, but for us we need the surface tension breaking of the water wetter but year round

 

water wetter with freeze protection would be great...

the OPs problem is air flow though... lack of.... small puller fan is not going to do the job especially with no shroud...

direct air into the front of the radiator...

 

Make some channeling ducts or something to direct more air flow to the radiator. Block off that open space in front of the manifold

 

Okay here's a question... I'm currently running a single core Fluidyne Radiator... I didn't think about it until after reading a few other threads, but could I benefit from picking up an ebay or Mishimoto 3 core/triple row radiator?

Since the more surface area the radiator has the better it can cool, will the same size radiator with 2 extra rows really make a difference?

 

I still agree and will be looking into building a ducting system to push more air through the radiator as it's not receiving as much air as it should be... But curious to hear what others think about the 3 row radiators since I bough my 1 row Fluidyne about 6-7 years ago... Still a nice radiator, but technology has changed a bunch since then...

 

yes getting a larger radiator is always a good thing if u can get it to properly fit with proper airflow...

id fix your airflow problems first

just do the tony palo t1 integra radiator and youll never have any cooling problems lol that custom radiator he did is like 6 inches thick...

 

I was actually looking into having a custom radiator made for my set up, but that will be mucho $$$!

The reason why I asked about the 2 core/3 core radiators is because their measurements are exactly the same as my 1 core Fluidyne... So the internal layout is different, again do you think with an extra 1-2 rows with the same size radiator will help my cooling efficiency?

 

bump

 

Found a couple of decently priced 10" fans that have increased CFM's by 150-300... Is that worth spending money on?

 

you need to do more research on what other people have done with success when it comes to cooling...

its very simple you need to put a bigger fan on your radiator that is a puller... if you do not do that you will not fix your overheating problems period... it that requires you to change other things to give you clearance, relocate the radiator or replace the radiator with something else like maybe the chasebays radiator then that is what you need to do... there is no cheap resolution to your problem...

redoing the intake would allow more clearance...

 

I guess what I'm trying to get at is what's the most effective way to drop a solid 10-15 degrees at highway speeds? I believe my set up in general is as good as it will get with my current header and small engine bay... I'm pretty sure my goal of 10-15 degrees can be acheived by the combination of increasing the % of water in the ratio, two installing a air duct to direct the air through the radiator instead of around and three I'm looking at a 16 row oil cooler to further help keep the temps steady on warmer days... Will have the temp gauge installed shortly, but the warm weather won't be back for atleast a week so I'll have to wait to update my actual temps and what actually help?

Thanks again,

 

^I'd go bigger on the oil cooler. I'm going to fit a 36 row on my dc2r if it kills me. 16 row did nothing for my temps.

 

if you redo your intake hose you will have more clearance to put more fan on your radiator...

make a wall on the left and right side of your radiator so the air that passes by the radiator on the sides will be redirected through the radiator...

 

This looks very interesting. did you use the prep fluid or just flush and fill?

 

Yeah I was thinking a little bigger, but what are the dimensions of a 36 row, that's huge! I think the largest I looked at was a 26 row! Either way it should do the trick on it's own, but I still have to address the air flow issue through the radiator...

 

Good idea, I'll see what I can do along with the air duct system I'm working out... Thanks!

 

id like to point out that the thicker the radiator, the bigger the fan required, the denser the radiator is the harder it is for a small fan to pull air through it, especially without a shroud

 

Good point, thanks for bringing that up! At this point I'm going to do a few things that was suggested as I'm sure my currently Fluidyne can keep up with the temps provided the air is flowing through the radiator... And a large enough oil cooler should just add extra insurance to make sure the temps are were I want them!

Thanks again,

 

So i finally got the Cyberdyne Temp gauge up and running... Installed the Header blanket on top of my wrapped Ramhorn, and now have about 30/70 coolant w/ water wetter...

Was rainy today, so no test drive until tomorrow... But the only thing left to do is reinstall my finished air damns, and seal up the gaps between the radiator and intercooler.

The header blanket is awesome, it's not the prettest thing, but I'm suprised more people both domestic/import don't use this stuff! My temp gun showed a reduction in radiant heat off the headers from 500+ to just over 110! I can literally hold my hand on the headers for 3-4 second without being scolded!

If all of this doesn't do the trick I'll be getting a 16 row oil cooler. Stopped by to pick up more Motul from my tuner today and he was worried that a 25 row oil cooler might cause oil pressure issues since I'm running a turbo... (Ls/Vtec Turbo, fully built)

Any of you guys ever hear of an issue with oil pressue w/ oil coolers on turbo honda's?

Thanks in advance!
