Heaton question

[Stupercharged]

just wondering if someone can explain why the eaton makes so much more heat than a twin screw? is it because it doesnt create boost internally like a twin screw and therefore it is trying to push atmospheric air pressure into an area filled with greater than atmospheric area? i dont understand? and how does a port help the heat issue?

first off it has a small displacement compared to a ts....the more boost ( pressure) you try to push through it the more heat the blower will make since the air is going through a smaller orifice.... when you port the blower you increase the displacement and smooth out some air passages which brings down iat and therefore increases psi. some more experience eaton will chime in ..pretty sure they have more usefull info on this subject.

nobody knows anything?

Yeah, actually Eaton's have not cornered the market on heat production. Twin screws have the same general characteristics and have the ability to generate plenty of heat as well. "Frying an Egg" on the top of an old style Kenne Bell that has been put through it's paces, is a legendary phrase to those that have seen them run hard. Twin screws need extensive blower cooling mods like heat exchangers and aftermarket ice boxes just as much as Eatons.

However, the twin screw design if flat out superior to the roots design and has the inherent ability to get more air into the combustion chamber for sure. And also can handle higher boost levels with better efficiency as well.

Simly put because a Eaton M112 isn't as efficent as a TS there for it should create more heat at any given PSI. A Eaton's efficentcy range is lower than a TS.

Like the others have said its more restrictive hense it probably creates more friction with air molecules or something like that, and friction creates heat. I suck at Science though.
