Default How I made my TMIC as Good as a FMIC

Maybe even better, if the FMICs pipe back to throttle is not insulated. I decided to make my own thread up instead of going into other's and expounding on it there. http://s18.photobucket.com/albums/b111/wrxdrvr/ There are three albums, wrxdrvr, ICmod, & info... Basically I insulated/isolated the IC from under hood heat, added a water sprayer, Tilted IC, and made airflow out of the engine bay easy-er so that air flow through the IC increased.

Stock TMIC set up; 59% efficient.
New stock TMIC set up; 85% efficient.

EDIT: This was on an '02 WRX.

Uh, how are you coming up with your efficiency ratings? And those fans look ridiculous, I'm sorry.

I believe he has a temperature proble post IC so he can compare Intake Air Temp at the MAF vs Air Temp at the throttle body. Im still looking into fabricating some kind of sheet metal heat shield that will sit below the IC and hopefully block any radiating heat from soaking the IC so quickly. I wish you had more detailed pics of your setup.

Nothing, the only thing I have to be careful about is the pressure washer at the car wash.

Yes, that's what happens when you get colder than ambient air into throttle .

Bump for some more detailed pics of the heat shield. Does it run under the IC or just block the turbo area?

I don't have any better pics...didn't think far enough ahead. But yea basically I stuck a metal sheet that I insulated with stick on pipe insulation under/around the IC.

i wonder if it makes your drivetrain more efficient. It very well might with such a high change in efficiency. How much wattage does it take to run the fans

How many hp do you feel that you gain from the colder air vs. the hp you lose from running 5 fans? This is an honest question. I am not being sarcastic.

As far as the fans go, I don't think it makes much of a difference for drawing HP away from the engine through the alternator as they are just 12v 0.44A for two and 12v 0.20A for the other two. HP for my car is 225.9WHP figured out with a HP calculator using my 1/4 mile track time and speed/weight, is it as accurate as a dyno.? I would say yes, seeing as that's what most dyno's do, they just "calculate" the numbers they show too. I don't think any of this makes the drive-train any more efficient , just that the engine doesn't loose as much HP to hotter IAT than it would normally, tho I guess the engine IS part of the drive-train...

EDIT; Oh yes I could have bought a bigger TMIC or went to a FMIC but I still have the stock snail so I don't NEED one Just like most people don't NEED one... They just "think" they do.

I'd suspect that those fans are worthless, particularly the one over the hole what used to vent air over the turbo. If anything that one is now a restriction to air flow.

I'd save money and time by using a high quality splitter, turbo blanket, and maybe some reflective heat wrap on the IC tubing. Well, mainly just step one. Then a good turbo heat shield.

ugh, hate to break it to you, but even an STi TMIC is perfectly fine with your TD04...

Yes it would be, But you would still have heat soak... I have ZERO heat soak even when parked or driving in city trafic.

As for the fans, when moving they probably don't help much but when parked or in traffic I'm sure they DO help and help a lot.

Honestly, I think you exemplify some of the thinking in NASIOC, of taking the the simplest of problems and coming up with a solution that is even more complicated than it should really be.

Good job on the execution, not sure if cutting multiple holes in your hood is such a bright idea however.

Yea, that's what the wife thought about me drilling the holes, I was on about the 300th hole and she came out and was shocked... She shook here head and muttered something about calling out the guys with the white coats. But I told her not to worry I was improving the car...

I dont think this is the "simplest" of problems - I think heat soak is a big issue and I drive in stop and go traffic a lot.

I applaud your decision to try this out and the fact that you got results from it.

Wow - lots of uneducated hate in here... In fact - if you research "intercooler" and "fan" you'll see that LOTS of people/manufacturers use fans on intercoolers...

I actually plan on trying to find a slim mount puller fan to stick behind my tmic and to separate the tmic from the turbo with an insulated barrier...
