There is some sort of coefficient of friction on the tube that makes the length …
Can you (or anyone else) explain… because I can not figure out the difference….
… in an engine where you would have the carburetor attached with a tube to the cylinder (motorcycle) and you would increase the length of this intake manifold you would at some point experience the problem of keeping the fuel suspended in the air.. while velocity stack (carb and injected) on the breathing side increases the fuel/air charge in the cylinder (column of air keeps pushing) This is not what I’m going for… I’m looking for pur air delivery!
i just don’t see the difference between EFI and Carburetor in regards to air only delivery!
yes, there is a boundary layer inside the tube that doesn’t move because of friction caused by the tube surface but add 1/2” to diameter should take care of that..
Looking at the EFI setup the hoses are anything but “streamlined”
The original air cleaner has a snorkel on it for about 12 inches long…
would a 4 inch diameter tube 30 inches long be more restrictive?
I would like to know….
it’s not about “everyone is a critic “ or the song thing… but just going for “because I say so” doesn’t count…
