Thread: open cone?

There's only one way to know about knock... SCAN!

an open or HAI in the engine will not be as good as a CAI or FWI. it will suck in hot air and probably cause some knock but there is no way to tell without a scan. its not always a huge drop in performance but some notice it more than others.

maybe this will shed some light on the subject.

At the end of the day , you want the biggest possible filter you can find on there.

You really need a larger filter than the 9"x4" that fits in a CAI box?

the tubing going into the CAI box causes a restriction in flow in comparison to an open cone. you want as much ability to flow as you can.

on a our cars it really doesn make enough of a difference to matter....

On our cars more airflow is better than colder airflow. because even with a "cold air" intake the air is still going to be pretty hot. it flows way better with open cone. and you can hear the blower wine a bit more which is nice

Your welcome...aren't you so happy I made you go open cone years ago?

But what kind of driver are you if you're racing people in the city and need that last bit of power just to beat the guy....

I would say the track is more comparable to city racing, wouldn't you?

I just don't see how 50* higher intake temps is negligible (what I saw on the highway all the way back from work today)

should i put a box over my cone or not?

here is mine, no box, no nuthing, works great.

How would an intake mess up a stock car?
