I was recently looking over my CT Icebox and I noticed something that I can't make heads or tails of for the life of me. Here is the coupler between the intake manifold and the intake:

As you can see there is a fairly significant bend in the actual coupler, does this make sense? I changed it out for a straight coupler this weekend but I am curious as to why it would have been designed like this in the first place? To me it seems like there would be turbulence from such a sharp shift.

 

Is it possible it bent from being stressed continuously? If so, the same thing will probably happen to the next one.

 

Its possible but Unlikely. The bends on the coupler are perfect, I think it is how it was made.

 

Wow. My guess is that the intake tube was designed for a different car, and was "good enough" to be repurposed for the S2000 too. Fewer SKU's = more profit.

 

wow, that must have cost you few HP just by looking at it...

 

It was from comptech, they do/did specialize in Honda's I can't imagine they would cut corners... but the proof is right there. I should mention I bought the exhaust from a member of s2ki, he put 100mi on the intake before he sold it to me and claimed that everything on there is a 100% stock, I tend to believe him.


I do feel that when you are at around 3+ K and you stomp on it they car seems a little more responsive, but then again that could all be in my head.

 

The angle is far less than a 90 degree bend or multiple 90's used when boosting a s2000. Also the stock intake arm has ribs on it and if you add all of the ribs up you have quite a bit of turbulence as well. Id says its perfectly fine.

 

 

This isn't a smooth 90degree bend it is sharp shift, sharp enough that it could effectively shrink the size of the pipe as far as airflow is concerned because the air will hit the wall of the coupler when it reaches it

 

whoever you got it from probably had it installed wrong for a long time.. those couplers will do that if they are forced to be distorted over a long period of time.

I have seen a number of these intakes and never seen one like that.
