I saw a thread on here not too long ago about home made powerpipes. A couple of them looked pretty good. While my car is off the road over the winter I was thinking about building one. Then, I just saw this http://forums.corral.net/forums/showthread.php?t=1064051 Do you think there is any validity to it being as good as a powerpipe? Seeing as though the air is being drawn right from the engine compartment, I don't know what to think. Any thoughts?
