Kurt, I wish I could do cold air intake from the fender, but on my GS-R there wasn't an intake in the fender well, just a sealed resonator.  I think it was only the Type-R that had the in-fender intake from the factory.  If I thought I do a cold air intake, I'd be all over it .

Some more notes on the test.  The "baseline" intake was the one I currently have in the car.  It's approximately 26" long and 2 5/8" inside diameter.

The plumbing pipe was 3" inside diameter.  I used a 15 degree elbow directly off of the throttle body so that the pipe would clear the fender, then straight pipe for the rest.  With each length I did several pulls until the torque numbers agreed with each other.  I then took the two curves that most closely agreed with each other and averaged them out to get the final curves in that graph.

There's a hole, Paul, but it isn't legal for IT/IP.  Intake location needs to be stock or inside the engine bay.  Inside the fender is neither stock, nor inside the engine bay.

From the IT rules, D.1.c - "Air intake source shall be
within the confines of the engine compartment or stock location."

Is air drawn in from the fender well with the stock intake on a GS-R?  No.

Where is the air drawn in from with the stock intake on a GS-R?  The engine compartment.

Seems pretty clear to me.  Just because the piping happens to pass through the fender well doesn't mean that's where the air is coming from.

Maybe it fell??

Picture tells the story..  Looks like the 92 GS-R Takes its air from the engine Compartment..I was wrong about the fender intake . I always understood the 91-93 non Vtech B18s to get there air from the fender. SCCA is looking to clarifie the rule, to engine compartment only for everyone.  Over the years i have done extensive testing on air intakes and flow and air temp,An engine is a gas powered vacuum cleaner drawing air through a pipe, The less strain you put on the engines ability to draw air the better, Atomizing the air is critical, and drawing fom a Low preasure cool source ,My testing has revealed that this can be created bye a 3in pipe , covered bye a 4in pipe . to a 4in K&N . My proto type intake has proved this in vacuum testing . Havnt had time to finish the build....  Now there is the same intakes on the market. Dual Chamber Air Intakes .all this stuff only works if you can get the Exaust out with its least resistance[Low Preasure scavange]. Point being that all these things have to be addressed or its a mood point..... This is my 2 Cents....

you're such a dik

As opposed to yourself, Mr. Ex-Prez, I have never professed to be an expert in anything related to cars or racing and was only asking Jordy who obviously has a wealth of knowledge on this particular subject to explain what I obviously did not understand. The question now is, is there some advantage to the large air resonator that Honda/Acura has designed into that system which as Jordy states does not draw air into the system but must have some useful purpose ? Maybe by the time we have invested in a cold air type intake system the resonator serves no useful nor performance enhancing advantage ?

If that is the case, maybe it's all the more important to keep it as we are trying to stay under the sound limit and the wail of those hamsters is deafening.
