Arrow question about FMICs

Just curious as to why people are deciding to go to a FMIC? What research did you do to come to your conclusion? Can someone post dyno-graphs or something of a car that had a TMIC and went to a FMIC?

In a perfect world, you would have an IC that is the size of a FMIC mounted where we put the TMIC. You ALWAYS want your IC as close to the throttle body as possible. With a FMIC, there is so much piping on our cars that it seems that it would cause pretty bad throttle response (under boost and vaccum) and a lot of pressure loss for a while.

So, please convince me that the FMIC is the way to go. I might do this if I you can do this, but you have your work cut out thanks

The FMICs have much higher air flow due to their position and do not suffer from the heat soak problems of the TMIC. The trade-off is that all that piping for the FMIC has a negative impact on throttle response and exposes the piping to a lot more heat as it crawls all around the engine. I plan to stick with a TMIC.

What an odd question. An intercooler operates very much like the radiator in your car, but rather than cooling liquid it is cooling air. Why would water splashing it do any harm? Many rally cars actually have water jets spraying their intercoolers to lower the temperature.

ben i think Penguinking is just a little confused on how an IC works

penguinking, an IC cools the air that is brought in from the turbo and intake. it doesnt bring in anymore air than what is already there. i think you are confusing it with an intake, which you dont wnat the outside elements clogging.

A front mount does not let the heat from the motor warm it up. Sure as we are going down the freeway it's no big deal to have a top mount since there's lots of air flow. The front mounts though are almost always going to be a little cooler and therefore better for overall performance. The downside is all the plumbing.

On another note, if you check all the 10 second Imprezas at www.autospeed.com, you'll see that they all have front mount intercoolers... well that and a 2.4L stroker motor.

This is a confusing subject, but I'll take a stab at it.

When picking an intercooler you must examine what the motor is going to be used for. Here are a couple of examples.

If drag racing is the soul perpose of the motor, instant throttle response isn't your main goal. What you want is the coolest intake charge possible. Heatsoak is also a major concern as the car will be sitting most of the time. Given this information, a front mount intercooler is best.

In my case I am looking for instant throttle response, while keeping a very cool intake charge. This is because I use my car for track racing, and hardly ever drag race. A top mount intercooler seves my perpose perfectly. Manifold Intake Temperatures are very low, and heatsoak isn't a problem.

Basically, examine what is most important to you and then examine how deep your pockets are

Cheers,

MattC

Cool

take one of those small freezers for aparments and dorms. rip it apart and take the cooling system out of it. hook it up to your alternator. stikc it right near the throtlle body and there you go. nice and cold intake charge and can keep a soda or beer cold.
