Ok I am doing my research on which IC I am going with so I am asking for some help from you people here.

There are alot of members here so I am hoping this provides the results I expect.

I need this.. I would like to get the engine running temps of those using a large FMIC.

I also will need the running temps of the cars using SMIC.

If you could please state simply your IC, temps, and where you purchased your IC at.

Also if you have a vented hood,aftermarket radiator,upgraded oil coolers or any other cooling mods please make me aware of that with a small side note if possible.

Thanks ..

GReddy FMIC 2-Row, MazdaComp Radiator 30%coolant/70%water

Water temperature depends a lot on ambient and how fast the car is moving. Right now in the bay area, ambient is around 40-60F. Water temp also depends a lot on load..but i'll just tell you cruising speed temps.

At idle/stoplight = 180F with fans on...Climbs up w.o fans
30mph = 195F or so w/o fans ....will drop to 180 with fans
70mph = 185-190F w/o fans
100mph = 180F w/o fans
120mph = 180F w.o Fans

Fans make a huge difference. And from my stock intercooler to FMIC, my temperature didn't change much. The only thing i noticed is that on a HOT summer day, i'd have to use the fans more at highway speeds.

I'm surprised that you didn't notice much difference from stock. What were your stock running temps?
Did you notice a large temperature drop when you installed the Mazda Comp Radiator?

I'd like to see the road racing FD owners post their info here as well

Yes please. Where is Max Cooper? I know he logs this stuff.

My car had the mazdacomp radiator on it when I bought the car, so i can't comment on before/after. I would say that when it comes down to it, it's all about ducting and fans. Even during those hot 100F days, i can just leave the fans on Medium, and my temps won't go over 190F.

I've noticed a huge difference going from stock twins to big single turbo. My water temps now don't increase when I rail on the car, they DECREASE.

I'm equipped with a FMIC, KOYO radiator, no a/c, POWER FC turning fans on at 85 and 90 celsius, vented hood, foam between the FMIC and radiator(to force air thru the radiator), and the lower plastic shroud in place.

I haven't logged my stuff in a while, but the biggest difference in water temps was definitely the big single.

I'm about to go with a GReddy three row on my single setup. I have a bunch of logs with the Datalogit and I'll run over the differences once I get the FMIC installed. Honestly, the ONLY reason I'm doing this is packaging. I have a Crooked Willow IC and a T78. A good sized K&N filter doesn't fit and I'm not willing to throw on a $250 piece of crap HKS :-).

Running a GReddy SMIC, Fluidyne Rad, Evans NPG+.

Bought the IC at Rotary Performance, the Fluidyne at MZM International.

I've only once seen anything higher than 87-88C, that was 90C after ripping on it at the autoX (six straight runs). So ~190F peak.

CW dual oil coolers are on their way!

I have FMIC envy. I was all set with the Greddy 2-row, until you had to go posting about your 3-row

Seriously, Jason Baughman's checking on the 3-row application for twin turbos. If he has one, I'll probably speak up for it, along with some sort of open intake like the Apexi...
