What problems?

A FMIC cuts your amount of air available for heat transfer in half. Personally I would run either a insulated smic with a fan or a Vmount.
Also, if your dead set on going with a FMIC, dont base your decision around other people experience with difference IC/radiator cores. Just cause one fmic doesnt have problems doesnt meen your will or wont. Every core is different. The more fins it has the better its going to cool the charge air, BUT the more its going to kill the radiator. Also, due to fin design different radiator need different amounts of air flow. If Steve felt the need to put that one his website, I'd at a minimum call him and talk to him about it. I seriously doubt he put it there for no reason.
just my .02

Don't forget the A/C condenser that sits in front of the rad core LOL.

No. I have a fluidyne with the stock front and a huge greddy FMIC. Never see temps above 104C. But then my fans come on at 97C

let me rephrase the question. For those of you seeing the higher temperatures are you using the stock front end? also is it just the KOYO or would you have the possibility of the same issues with a FLuidyne or other aftermarket radiator? Last but not least, is everyone who is having the problem using the GReddy or are other FMICs having the same problem? i will make sure to spell things out for you from now on sleepr1

Yea, didnt even think about the condenser....mostly cause I dont have one haha
But still, ac condensors are designed to flow as much or more than the radiator and dont transfer near as many btu's into the air as a fmic or radiator does so they arent as big a deal.

Good for you. You've traded peace-of-mind for warmer AITs, and lower rwhp.

I am still amazed at how low other FDs water temp is in normal driving conditions durnig the day with 80F out side. Some of those temps are on 10F (80C) warmer then the stat opening. Dam.

Just get a V-mount, and end the debate. V-mount offers the best of both FMIC and SMIC.

I've seen 120 C (248 F) for a couple of laps during a hot day @ Putnam Park. No real problems. I don't recommend running at the water temp for an extended amount of time.

104 c is the highest that I have ever seen, which is about 220f. True thats warm, especially compared to others on this board. But it is not the breaking point. If I were to see it hit 110c (230) then I may start to worry and turn on the heat, pull over, you know things of that sort. I also know that my mixture is more coolant then water right now, so that could be part of it. That will change soon. The stock front end does hinder cooling and I am sure that affects it too. But once my fans kick on the temp sits right at 90-94C (194-201f) which is well within a normal operating temp.
I am still amazed at how low other FDs water temp is in normal driving conditions durnig the day with 80F out side. Some of those temps are on 10F (80C) warmer then the stat opening. Dam.

Water temp sits at 85~89. During tuning sessions taking it from 1st gear to the end of 4th gear my water temps climbed to 95~ ....lol... with my oil temps at around 95~, but soon coming back down to 85~ and eventually 80.

Mike , I put a Greddy FMIC and Cool Racing 3row full racing radiator in mine and it's way bigger than the Koyo so fitment issues and heatsoak shouldn't be a problem with your Koyo . What I recommend is use Distilled water and Water Wetter for your coolant system ( along with your favorite anti-freeze ) , and at first it took us a while to " BURP " the radiator . That was the ONLY time I saw a potential issue with overheating . Once you get the radiator burped or free of air bubbles , you'll NEVER see high temps again ... even after running it hard . Good luck , it WILL work for you , just keep purging the air from the rad ...
