OK, first off I wasn't too sure where this topic should go so if it must be moved, so be it ;)
I am going to be making the "home depot special" intake for my car. I was going to use some PCV piping for the tubing. I was telling my plans to a corvette guy last night and I was telling him that I was planning on using 3" piping. Then he started telling me that he didn't think that the 3" pipe would be the best choice. He told me to go with 2". I was like WTF!? he "explained" to me that the 2" pipe would create more of a vacume for the air, and it would tavel faster to the intake. He said "do this, get a 1' long piece of 3" and 2" pipe, put one end on your mouth and start to suck air, when you do this put your hand on the other end of the tube and feel the suction the the 3" pipe creates. Now repeate the same process with the 2" pipe. Feel how the two 2" pipe sucks harder? that is what you want, it creates more of a vacume and the air travels faster to the intake." Now at this point I was still confused. I told him that the 2" is more of a restriction than the 3" was that is why it was "pulling harder" and that the 3" was able to get more air to the intake better than the 2" was. I wanted to use the 3" pipe because that is the "size" that my Throttle Boddy is. So I guess my question is this How much more air will the 3" flow than the 2"? can we prove to him mathmaticly that the 3" is better? sorry for the long post :D
Thank you for any light that you can shed on this subject, and again if this topic is not in the right section I am sorry, I just didn't know where to put it. TIA for all your help! [img]smile.gif[/img]
