where did you get that info from^

 

I was at Church's Automotive last week. He has a "CAI simulator" that was hooked up to my car. It was dyno'd and I lost 7rwhp. Therefore, I can state with first-hand experience that a CAI will loose ~7rwhp (peak) on an MY06 S2000.

 

Just get a K&N, a TINY bit of performance, but the filter is cleanable and reusable.

 

I agree...I think replacing just the filter is a waste..but that's just my opinion...I've ran a JR, Spoon, Comptech, & K&N in the past...nothing exciting to report.

 

What is this "CAI simulator"?

I only ask because a simulator doesn't 100% imitate reality.

I'm not saying CAI's make top end power on an 06, but without dynoing back to back with an actual CAI that exists in the physical world I wouldn't say that you'd lose power either.

 

"CAI Simulator"... if this is just a simulation, it doesn't necessarily mean that that's how the car will react to an aftermarket CAI.

The "CAI simulator" I was referring to is basically a piece of piping, which looks like CAI piping, and instead of having a filter attached to the end it has a specifically designed "mushroom" end. I wish I could have taken a picture of it. When attached to the throttle body, it acts as a CAI, with exception that it provides even greater airflow.

 

k&n made modifications to the FIPK/install process to allow use on the 06 model. I have no knowledge of loss of HP though

 

I can see two problems with relying on such a CAI simulator to dyno hp and torque gains and losses from a CAI.

First, the ECU must be reset to account for the different intake. xviper has a good explanation on this somewhere on this board. I recall that it involves disconnection of one battery terminal. xviper goes on to say that, as an alternative, you can just drive the car a couple of weeks or so and the ECU will reset itself. So what I mean here is you can't just install a CAI or CAI simulator and dyno the car immediately after, and get an accurate result. The ECU is set wrong when the "with CAI" test is run.

Second, many CAI's, both "store bought" and specially fabricated, include a "ram air" function that does no good unless the car is rushing through the air. In fact, a car with a CAI that incorporates any "ram air" effect cannot be accurately evaluated by dyno (even if the ECU is properly set) unless a rush of air is supplied to the intake point at the time of the dyno test.

I don't mean to be disrespectful to 2QYK4U, but merely want to point out that a dyno on a "simulated CAI" has some accuracy problems unless the ECU is first reset, and unless ram air is supplied somehow (in cases where the particular CAI uses ram air).

Thanks,

Your statements may be legitimate. I am not the one to question them. Best thing to do is what for a CAI to be developed for the MY06 and see what the differences are.
