Pipe Flow

[ugy]

Hi, could somebody tell me what a 2.5" pipe flows as opposed to a 3"

Thanks

Could someone tell me how long a piece of string is?

He took off the cat put a resonater on that had an inlet of 3" and outlet of 2.5 with a length of 2.5 to a Y section into the twin 2.25s. Not a happy camper

if you want to know how to work out what 2.5 inches of pipe flows do this.

1.25 x 1.25 x 3.14 = 4.9 square inches, 1 square inch flows 146 cfm @ 28 inches of water so its 146 x 4.9 = 716 cfm BUT most people quote 20.4 inches when they supply flow figures for carbies or exhaust components so you then need to work that out like this. 20.4 divided by 28 x = square root=.7285713. Then multiply 716 by .7285713 = 521 cfm @ 20.4 inches of water. I hope I did all that right I havent had to work on flow like that for a couple of years, I usually just use a flow bench lol

Thanks for that Simon, so I should be happy with that a lot of hi flow cats dont flow that good.

I don't see how your going to work this out. The guts of the cat will effect flow also. It's not just a matter of finding out what a sertain size pipe flows.
