I just got my intercooler in the mail!!!!

[sleeper3]

From what I know, the performance difference is centered around the fact that your intercooler is being used to cool air, and a TMIC is sitting ontop of your engine. Not sure about you, but last time I checked, my engine bay is pretty friggen hot. Also, idk about this so correct me if I'm wrong, but when I look at the intercooler housing on the top of the hood, I don't see anyplace for the air to go once it's entered.. seems kind of like a bad design to me. Can anyone shed some light onto our intercooler ducting design?

Of course you can get into the argument that if it's a TMIC, the air has less time to travel less, and so you spool faster.

But you could also say that if it's a FMIC, the air has more time to travel, and thus would compress more and give you more power.

Overall, I believe -- that is, in my opinion -- that FMIC's are better. Perhaps not by much, but they're better.

I've heard that the ETS TMIC stays real cool, like ice, even after hard driving. If that's the case, it's a large improvement over stock.

and OP, what were you saying about tweezers? were the fins bent or something when you got it?

Post pics!

lol

ok here are the FACTS:
1. yes, top mount intercoolers do suffer from heat soak, which is not as much of a problem for front mounts.
2. the air goes through the intercooler. I'm not sure how you're not seeing an exit.
3. the farther that air has to travel, the less pressure is maintained. I could go into a fluid dynamics discussion, or you could just take my word for it.
4. No intercooler on the market (excepting of course liquid to air intercoolers filled with ice water) will be "cold as ice" after running. intercoolers are cooled by AMBIENT air, which means that they will never be colder than the air temperature of the outside air, and since the turbo is trying to heat it up, it'll never even get that cold.

Time for a water sprayer for the top mount. (dunno)

I'll never put one of those on my car.

CryO Sprayer?

 

[sleeper3]

no thanks. personal preference, but I've never wanted to do something to my car that is not on all the time, or requires maintenance (meaning getting co2 or nitrous fills)

Exactly, there pointless. I had one on my STi and I think I used it twice, both times while I was logging and it made no difference.

Personally, im waiting on the Cobb FMIC, I hope they have a better design than the FMIC's that are out currently.

I am in love with the corksport set up. I think down the road I will swap what I have for that.

PTP is coming out with a big FMIC. (outie)

ptp's site confuses me. they sell like tubes and stuff... and erector sets.

3. the farther that air has to travel, the less pressure is maintained. I could go into a fluid dynamics discussion, or you could just take my word for it.

What I find amusing about this point is that when many of the posters here talk about turbo lag it sounds like they picture stepping on the gas and the air that is coming into the intake at that time gets compressed and sent through the intercooler to the motor to be burned with the fuel and it has all that distance to travel. The turbo lag is the time it takes for the system to pressurize and push the air already at the end of the intercooler into the engine. The reason more plumbing and a bigger intercooler contribute to lag is the increased amount of air in the system that needs to be compressed. This greater amount of air in the system also contributes to the brief jumps (and drops) in A/F ratios that loggers see when they stomp on the gas. The more plumbing involved, the greater this effect should be.

John said all products are in testing and should be posted on their website in three weeks.

it's amazing how much knowledge people claim to have and yet they will consistently lack even the most basic understanding of how things work.

and if you think gr3y knows what he's talking about then I pity you.

My engine bay last summer was way too hot. This one is a major concern for me. Thats why ive been asking about Intercoolers spraying, ducting, Charge temps. Next, Air is forced through the top of the grille into ducting to the top of ic and exits onto top of motor. Another issue for me.Spooling faster, I have not the education to comment on this one. I think that a fmic would function better also, but stealth is a key factor Hope i helped on your ? grey
