I always tought that gas intake should be as smooth as possible,But

my buddy raised suspision in my head.

He said that if its rought it would spread the gas better" wich somewhat makes sensel" and that the explosion would be of a better quality.

 

What do you guys think?

Are you talking about the intake on the cylinders? If so, it should be rough.. When it is ruff it creates a better air/fuel mixture. Every cylinder ive ever see that has been ported has a rough intake. And if you really get into porting, when a builder does your cases, he will rough up below the crank on the cases for the air/fuel mixture.

Correct. Only it doesn't "spread the gas" or anything...what it does is causes turbulence that causes the air/fuel mixture to mix into a more even emulsion. But I dunno...I could be wrong.

making the intake rough helps to emulsify fuel and causes the mixture to" break up "so to speak which aids its burn in the cylinder head .there is a bad reaction that happens with an ultra smooth finish in which emulsified fuel will stick to it as its being pushed/pulled over its surface and it basically sticks to itself(all bad things) i forget the technical name for this

process,but you get the idea its important to be rough there , but you want the domes and exhaust tract to be very smooth :cheers:

Im sorry but neither of these mods will produce any difference, i don't believe its even been proven, besides theory. Not to sound like a dick or anything, but I would really not worry about this, unless your taking off excessive amounts.

That would be called the "boundry layer"

what you talkin about? if you are talking about whether or not to make the intakes rough i would check around to all the builders. i bet you wont find any that make them smooth as glass.
