i dunno, 95C cruising is a bit high... and for track duty, with temps easily approaching 100-105C or higher during lapping, it sucks.
My car with the stock intercooler now runs at a very nice 81-84C on a hot florida day. Only time my fans engage at 85C is when i have to stop in traffic for a period of time.

It has been proven REPEATEDLY by many track guys over the course of several years that FMICs are no good for track use. With proper ducting and fan management, they seem to be OK for street/drag use.

I have seen 85-88C while cruising. 95C is sitting in traffic in 90 degree heat. That is also with a 3 row front mount. As I have said the FMIC is not good for a track car, but great for the street.

There really isn't a set boost level as far as what the 2 row is efficient for. Everybody says 15-17 lbs, but there are too many variable to actually say. Where most of the variable come from is actually the Turbo itself, the more efficient the turbo is, the better the intercooler will cool. So if you have a GT-35R at 20 lbs it is 65% efficient, the FMIC is not going to cool it down enough to have a nice AIT. At that point, it is almost a Hairdryer. While on the other hand, if you had a 40R, at 20 lbs it would be about 78% efficient. Becuase the 40R is that much more efficient than the 35R, it will hit the intercooler at a much cooler temp, thus exiting the intercooler nice and cool. I have ran more than 18 lbs on my 2 row, I know many people who have. It all depends on porting of the motor, and the turbo efficiency.
I realize that most of you are talking about coolant temps rising. However it seemed like a few of you were under the impression that the Greddy 2 row is not good for mid to high boost levels, which in fact they are(given the proper set-up).

this thread is treading on thin ice....
it is getting closer and closer to degenerating into (yet) another fmic/smi debate.
that said, i say it all depends on what you plan to do w your fd. i agree 100% w Rynberg. if you plan to track your car you won't be happy w a fmic. you need a direct shot of air at your coolant radiator if you are going to be lapping w your right foot on the floor.
i also don't like putting a big heavy object on the front of my car when i am trying to get as much weight on the rear wheels as possible to go fast on a road course.
further, think of all the stone chips we accumulate over time... they are all headed for your IC is it sits upfront.
the ASP large medium takes a huge bite out of your charge air temps and i recommend it. you might find one w tubing and duct on our classified section or contact member kevin wyum who is responsible for the IC's design and may still sell them.

I have the greddy fmic with the stock rad with no cooling problems. Even this past summer in stop and go traffic, i barely saw 195F or higher. IF i boosted once or twice, it would top at 200F but never more than that. I actually had higher water temps when i had my pettit smic.

aluminum radiator and 2-row greddy here, and i have been driving without a skid plate forevers, and i have never seen temps above 92 on the street, but i dont drive it hard for long, i agree with the concept of tracking using smi or vmount, but like villision said, its more than just intercooler setup that is going to affect your temperatures
P.S. it runs at 85C under normal driving conditions, about 88C at a stop

I had a SMIC on my car and now a Greddy FMIC. I wish I had kept the SMIC.
With the SMIC, I would run in the 80-90 degree area in stop/go traffic in summer (90 degrees). With the FMIC, I now run 95-100. Fans are set to activate at 85low, 87 med, 89 high (degrees).
I'm also getting sick of the way it looks. Looked cool and agressive at first. But with all the ricers running and (posing with) FMICs, I'm beginning to feel self conscious.

Have you thought about a V mount?

i have a Greddy 2-row with no problems. i saw no difference in water temp when i installed it. my normal temps have always been around 80°-82°C or 179°-182°F..

I went to a HPDE at Rockingham last summer around June or July. It was hot but not that hot. About the 4th lap of the first session I broke 100C - I was running minimum boost of 10psi. By the 7th lap i was 105C+ and I started short shifting the straights to keep it from climbing. I was able to keep it at 110C but it wasnt nearly as fun as it could have been.
I did not have anything ducted at all - not even a shroud on the top of the radiator. I plan on trying to keep the FMIC with alot of creative ducting but if I had to do it all again I probably wouldnt go with a FMIC on a track car.
Who knows if I will get where I need to - I do beleive it is possible (unlike rynberg) but I am sure I will spend far more time, money and effort than I should to get it done.
Take that info however you want....

But with stock bumper, the small front mouth is made smaller by the end tanks that are exposed, and the core blocks half the remaining area. No problem for street use like Jason said, but you will use the fans more for cooling.
For road course use, with stock bumper, the true Apexi is best fmic (cew's ride) as it is set back and allows air to bypass the IC. The Blitz is still pressed against the mouth, iirc, but at least it's all core there and no/minimal end tanks.
