I have to agree the t-bolts and the silcone used on the Fujita intake are much better than the injen stuff. the Filter on the fujita is much much better than the injen. but i still dont see $200 difference. Im still a fan of the Stock Air Box with a K&N and call it a day.

Smart man. Your APS CAI is plenty good...

Now get an mbc, bov, and tune followed by cams and licp...

Most aftermarket intakes are prob designed by who knows what or whom and its fascinating hos 90% of them have a unique "MAF distortion signature"

The stock air box is very linear and smooth tunnel in which the air flow is measured in a very flat and even manner

Most aftermarket intakes have a consistant "distortion" of the mass air flow which changes the smooth and linear pattern and alters the tuning on the car

Ideally you would want a intake which increases the air flow ehile not altering the MAF sesnor air flow patterns

As a tuner, I have been able to work with a huge variety of intakes by researching the "pattern" of each brand of intake and making maps to match each specific intake by brand

As a result you wind up with multiple base calibrations for various intakes at various mods levels - (Stage 1 - 4 to use Buschur Terminology) and various octane and elevation levels

Most of the performance intakes LEAN out the mixture in the mid range which requires extra fueling in certain rpm and load points to produce a smooth a/f in the desired target level

As far as untimate performance its irrevelevant which intaake you use as long as the tune is set up to even out an distortions which exisit

I personally prefer the Buschur and HKS intakes as they seem to make the most power and are very consistant in hwo they distort the maf signal which makes for a consistant tuen car to car


This new intake concept of the "tuned" intake is a performance intake which mimics the MAF response of the stock air box and is "tuned" so that the a/f is not effected and distorted by the intake

In other words the intake is "tuned" to the car

This results in a a/f fuel map which has all the same numbers across the power band

Once you realize what you are dealing with its actually easier to tune - but in this case I was tsrating with a standard INJEN map and it was way off and required an unusaly large amount of adjustment

I want to clarify what I have said as far as general explanation of what I consider a "tuned" intake by stating that I have no idea if this result I have observed is a specific design feature of this spefici intake of if it is just a coinicidence of design - time will tell as I tune more of these inatkes

Interesting post Al. I wonder if these Fujita guys are on to something with the Evo's?

Big Al, sir.
This makes pretty good sense to me now. There was really nothing out on the APS CAI when I initially purchased it and then when I started reading that the masses were using different systems, I thought that I'd made a mistake in purchasing it hence the start of this thread. I was under the assumption that because of my having the APS, that getting a mail-in flash was out of the question and it was going to take a custom tune to get things working to their fullest. Now I understand that's not the case. And when I thought that the Fujita came with the "true" LICP, I thought, "Winner!" I see that's not the case either.



On a side note and to keep the integrity of this thread in tact, Warrtalon, I do have the MBC and the Forge RS BOV coming just in time for my ECUflash. I'm excited to see how the car performs on my drive from Tacoma to Austin next month. The LICP and cams will have to wait until after Iraq.

As always, I thank you fellahs for taking the time to educate "da newbie". I have more questions and if I can't find them through the infamous search engine, there WILL be more threads started.

Thank you AL for another great post with useful information! Good to see we have some knowledgeable people on here without attitudes!

Excellent. Just be sure you do a Walbro fuel pump at the same time.

Eclipsed Evo

When I refer to the lower intercooler pipe I'm talking about the one that comes from the turbo to the intercooler. Ther other side is always the upper pipe no matter how many pipes there are.

We don't call it an up-pipe - that's on Subies. For us, that is the LICP. Referring to the bottom half the UICP is unwise on an Evo, because that whole thing is the UICP. You don't just replace one half of it...

Eclipsed Evo

Umm I dont think you read my post.

Warrtalon

iTrader: (6)

Ah yes, I didn't read closely. IF this is the case, then why did you say this kit includes an LICP when it clearly does not?

Eclipsed Evo

At Sema I was told by the Fujita rep that it included all intercooler piping. This is why I said it comes with the "LICP". After seeing all these post saying it does not I just now called Fujita to find out. I was told wrong at SEMA. The kit does not include the "LICP".

Eclipsed Evo

I 'm not sure about you but most people I talk to about evo think of the driver side IC pipe as the upper or UICP. Check out bushers site they even list it that way.
As far as Subies the up pipe is for exhaust not the intercooler.

You're just agreeing with me. I was trying to refute your claim that this kit came with an LICP when there wasn't one in the pics, regardless of what some guy said. It's likely the guy at SEMA was confused and referred to the lower half of the UICP as the LICP. When you said this kit included the LICP, the only assumption I could make was that you thought the lower half was the LICP. We're all straight now.
