7 racer:

Switching your fans on earlier will help the problem...do a temp fan mod to keep you cool and run the fans all the time. Seems to help me in stop go traffic pretty well, just give your car some space from the guy in front of you so you don't suck in all the hot exhaust air.

Our cars are so finicky that it may or may not be a problem. If you haven't changed your thermostat in a while it may be something to look at.

Wish I could go V-mount or Front mount...I like them both but have to seriously consider engine rebuild.

Off topic but would you go KDR or Pineapple? No need to reply on this thread, point me in the right direction.

I WILL DO A SEARCH.

 

Update on FMIC/Koyo Rad setup and engine water temps.

Venue: Mid Ohio Sports Car Course, Lexington OH, May 8/9 2003
Ambient Temps: Average of 66 to 72 F
Primary/Secondary Boost Setting, Power FC Commander: 0.80 kg/cm^2 (11.4 psi), Autometer boost gauge reading, 11 psi peak redline
Water Temp Peak: 103 C (217.4 F)
Air Intake Temp: 38 C (100.4 F)

Cooling Measures:
1. Straightened dual oil coolers' fins and FMIC core fins using a scratch awl
3. Added 3-inch A/C foam between the bottoms of the FMIC/Koyo rad cores and undertray to prevent cooling air from passing underneath the cores, thus forcing cool air entering from the nose to go through the FMIC/AC Condenser/Koyo Rad cores
4. Added A/C sheet foam to seal crevices between FMIC core in/out piping
5. Kept oil levels full

Traveling on the interstates @ 80 to 85 mph, with ambient temps in the high 70s F, yielded water temps in the 88 C to 90 C range (190.4 F to 194 F), and air intake temp @ 45 C (113 F). I had the A/C at full blast (which works--I have the Apexi Power FC Version 5.08, and a '93 R1), I hate being hot when I'm traveling!

The A/C foam held up to the engine heat with no problems. The foam seems to have helped divert more air through the rad core rather than underneath the rad core. The wall unit A/C foam is available at any hardware store. Look in the weather stripping section.

See my sig for complete list of mods.

 

Awesome SleepR1

 

Other measures I did not mention. 85% distilled water, 15% Dexcool antifreeze, 1 bottle of Redline Water Wetter. I hope this helps others with GReddy Type 24 V-spec FMICs who track their FD3Ses...

 

Excuse my ignorance, but what's AC Foam?

 

It's 2.5 in x 2.5 in strip foam that's meant to seal up cracks crevices when installing a window mount A/C unit. I use heavy duty carpet-tape (double-sided tape) to apply the foam to the undertray, so when the undertray is buttoned down, the sealing foam contacts/seals the bottoms of the FMIC and Rad cores.

 

Ok, I understand what the foam is now...However, I am not exactly getting what you are doing with it...You are using it to make a seal between the bottom of the IC and Rad? Is this an air flow deal?

BTW: what do you think about custom fabing an aluminum undertray with a small 0.5" scoup?...one that would direct airflow between the AC condensor and Rad.

 

and the undertray.

Yes. You're now forcing the air to flow THROUGH the cores rather than underneath the cores.

I don't think this will work.

 

Care to elaborate why you think it wont work?

I just want to know so I don't waste my time and money trying to make one.

This is what I had in mind.

 

Ahh...the pic helps. Well, the scoop might work...best of luck!
