Is there any benefit of larger SMIC vs large front mount?

Fans aren't the problem when you are overheating at high speed.

Think of it like this. I live in Phoenix, the air temp 12" from the road can be 130* easily, pass that through an inter cooler cooling 300* air, and add let's say 30* to the temp. Now, turn on the ac and heat the air up another 20*. How much cooling can 180* air do?
I solved my issue in my dsm with an air scoop. I have a sheet metal scoop on my car behind the intercooler, and in front of the ac coil. It pulls clean air up, and into my radiator/ac coil. I dropped 20+ degrees with this mod.

Picture would be great.

Spyder95VR4...I've got a 3" FMIC, oil cooler also has been relocated behind the fmic..AC works and I have a advance auto radiator...never had any overheating issues.

I just fabbed up a 3-4" sheet metal scoop, and bolted it to the bottom of the radiator support on my talon.

I ran a 3sx single pass radiator, 99 front bumper, greddy high pressure cap, FMIC, nsx/s2000 mugen, and an O'Reilly auto 12" passenger fan last year. Never had problems while moving and was about were I wanted to be after the thermostat while running ac on 100+ days.

After my car is running again soon, it will have ducting and a setrab oil cooler. Should be nice and cool.

All this is with an aftermarket gauge, by the way.

All depends on how you use your car.

Front Mounts just look more bad ass. You never have to answer "is that a vr4?" Although there are surging problems depending on what turbos you go with. You have to modify your front bumper/shrouding. I don't have any cooling issues with the 3sx single pass. If I had a 1g I would probably stick with sidemounts. I couldn't have a 99 bumper though without having a front mount.

Im a sidemount guy cuz fundamentally it just doesnt make sense to put a 4" wall in front of a radiator. My opinion.
Plus, my hks sidemounts have been really nice and only really heat soak during autocross. Im painting them black soon enough and that will help. Have been thinking of blacking out my IC piping as well, and manifold. Heat is the enemy!

I've never understood how any of you get overheating issues with a front mount. I never have and I've done long distance driving, peak hour traffic driving never getting out of 2nd gear. I think it's like Jason mentioned, poorly installed unit's or perhaps poor units themselves.

I ran a stock 92' radiator with a 4'' thick FMIC.

100 degree ambient... No problems, however, I ran a stock fan setup. Anything less... and I had problems. (Non shrouded temporary electric fans I had laying around.)

Its not really a wall though... It just artificially increases the air temperature hitting the radiator/condenser assembly with a slight drop in air flow.


I would be careful with just painting something black.

Edit: Removed "right kind of paint" special paints are too expensive to really be worth it. If you paint... make sure you know the local atmospheric and operational temperatures of each pipe you are painting.

2" radiator + FMIC is what I'm going to use. I don't know that I'd risk it with a smaller radiator, but I have faith in the 2" solution.
