(Looks at huge banner ad at bottom of page). Next we should test the Turbonator!

It supercharges any car! I would like a supercharged turbocharged WRX!

You should be able to swap back and forth without any problems or learning required, the only difference will be increased power.

I thought that the APS 65mm was one of the good intakes that acted like the stock intake?
Why whouldnt it need to relearn a new fuel curve? The intake flows differntly, right? Thats how it makes power, no? Now with a properly designed intake it will let the maf does its job, but they are all going to have some effect on fuel.

Well, if you do back to back dyno runs as others have and the A/F ratio stays the same, seems to me that there is no significant amount learning required or necessary.

You might get some additional learning at the higher air-flow rates and engine loads as you'll now be encountering those more often.

I'm assuming that this was tested on a STOCK sti ecu? How about if you have the cobb accessport running stage 2? Will you get the same results with the typhoon or is the cobb reflash specifically designed for the stock intake?

According to cobb its made for the stock intake. Which is why they have an intake map for the injen intake. IIrc the made that one because the demand was so high. Will it work? It may... but most of the people with AP's on the wrx end up pulling thier intakes.

The first statement is true. There is no map offered for the STi using an Injen intake, only for WRX users. The ECU on the WRX and STi are totally different, so what you are saying is no relevant to the topic.

There have been reports on the Cobb Forum of people using the Typhoon intake without any problems. They also noted that the AFR's did not change when adding the intake.

First of all:
There is NOT IAM factor in the STI ECU. There may be some other factor but IAM doesn't exist in the STI. All this talk of "ECU Reset is making the power" is absolute rubbish. His car would have to have been detonating BADLY and in limp mode for the ECU reset to cause an INCREASE in power. If anything, countless people have shown that the car's power will be decreased after a reset and it will rise run after run until it finds it det limit and backs off again.

I was one of the very early adopters of this intake and from the very start, I've said it makes more power than the stock intake without ****ing with the air/fuel trims. I have Tuna wideband permanently installed in my car so my judgements are qualified.

The single biggest restriction in the engine's intake path is the air filter. This is the MAIN reason intakes with large cone filters make power. By increasing the surface area of the filter, you reduce the restriction through it. This results in less pressure drop in the turbo inlet hose, which has lots of benefits for a turbocharger system.

VE is increased, intake charge temp is reduced, lag is reduced, etc etc.

To all the longtime naysayers:

This whole "agree to disagree" thing is such an overused phrase. How about this one:
You're stubborn and you'll never have a clue what you're talking about.
What a load of B.S.






















Good info!

But seriously! Some of you guys get too worked up over this stuff!

I hope this was sarcasm, as I'll readily have you search "pressure ratio" for an explanation of my claims.

It mates perfectly {biting tongue on juvenile response}. It does seem quite peppy. I had a Perrin and Apexi before and I found both wanting. I can't wait to see how it does with a GT12 and UR 785 injectors.
