I just finish putting my T78 and Greddy 3 row and Koyo radiator in yesterday. I took it out for a spin to make sure everything is ok. I would see my radiator temp go up to 105 degree Celcius. At cruising it is usually between 93-96 degree. Are these numbers high?

 

where you on boost for a extended period of time... ? was that the temp after some heat soaking ?

crusing around I am 85-88...SMIC, stock twins...

93-96 is slightly high in my book...I guess there could be something to what ppl say about FMIC blocking the radiator..

 

With stock intercooler and rad, i see 85c, with ac on highest is 90c. This is in florida about 85f.

 

I sit at around 88-96 c depending on outside temps and spirited driving....

from what I understand over 100 is a prob....beware.

Took the car out again today. Temp in the low 60's. Radiator temp was saying 93-95c . I believe yesterday I had alot of heat soak from sitting so the temps went up to 103-105c. Oil temps goes up to about 100-110c. And it has gone up to 120c. Is this o.k?

 

I think 120c for oil temp is about as high as yould want to go also....

when the lasttime you flushed the rad and changed the t-stat....where were you before the FMIC install ?

 

With the front mount you are going to run hotter the only way to keep the temp down is to run the fans all the time .
Good luck

 

Wire a switch into the fans to keep them on at all times. I keep them on and my temps are never over 180F.

 

The oil has reached 120c before when i was on stock sequential. I just put in the the front mount and the radiator the other day. This was all done when i did a T78. I don't know what my radiator temps was before because i didn't have the power fc commander to monitor the readings. It seems alot of people that have gone with the greddy 3 row front mount have been getting high coolant readings. I hope it doesn't get too high. I think i will try flushing out the radiator and just putting only distilled water in. I live in ohio but i don't drive the car during the winter. I'll post again later on the results.

 

How are you guys monitoring your radiator temps? PF Commander?

 

I have the water tem Defi guge and the power fc .

 

Use Water Wetter while your at it. It will help a little, but still not a fix.
I got the exact same setup and the same problem.
I just use the fans alot. I keep my temps anywhere from 180-210F. We need to get more air flow through the radiator. I have some ideas but no way of making it. Or atleast making look clean. BTW did you install the A/C condensor? I left mine off cause I was afraid of this problem.

I sent you a PM

 

Also Im going to call pineapple racing and see if they think Evans will help any.

 

i find that water wetter does not help me, i have used it in multipul cars and it has never had any effect, has anyone anyone acutally seen a difference in temp after using it?

 

...Me too. My Power FC seems to read a little hotter than my Defi water temp.

I have the datalogit equipment and I turned my fans down WAY low. I also removed the AC condenser so I believe that helped. Also pulled the thermostat(never gets below 65 degrees fahrenheit here in Okinawa).

I normally run in the mid 80's to low 90's. When I rail on it a lot, the water temp will climb to about 100 degrees Celsius.

Before I had the datalogit, and a stock mount IC, my water temps would run on the average high 90's to mid 100's railing on it. I still had the AC condenser up front though.
