Che'_Moderator Posted March 7, 2006 Report Share Posted March 7, 2006 So the volume doesn't change under boost.Wrong answer Che' You don't get to go to the lightning roundI don't even know how to answer that. Gooboodollyyyy!!!!! Link to comment Share on other sites More sharing options...
the underlørd Posted March 7, 2006 Report Share Posted March 7, 2006 this whole thread gets rated way up.. Link to comment Share on other sites More sharing options...
Che'_Moderator Posted March 7, 2006 Report Share Posted March 7, 2006 OH. And if anyone talked down to you or you feel like we mistreated you we are sorry. Atleast I am. You should file a complaint with the new HR moderator Jena. Just let her know who the offender is. Link to comment Share on other sites More sharing options...

Iron Monkey Posted March 8, 2006 Report Share Posted March 8, 2006 I'd like to contact Jena as I have been greatly offended. My once massive IQ fell 20 points. From what I understand that means my head must now get smaller. Link to comment Share on other sites More sharing options...

volvotuninguk Posted March 8, 2006 Report Share Posted March 8, 2006 So the volume doesn't change under boost. This is a blown engine not a N/A engine. Volume is not static.Wrong answer Che' You don't get to go to the lightning roundVolume is the static value used in the CR. The volume doesn't change. The turbo charger is simply compressing the gas in the same volume.If your theory was correct, the CR of a NA engine would change depending on ambient air density. But it doesn't change because it's about volume.Volume is always the same.Analogy - take a box 1m x 1m x 1m. That's 1 cubic metre. The volume of air inside is always 1 cubic metre. If you compress the air inside by pumping more in, you will still have 1 cubic metre of air, but the density is greater. Density is mass per unit volume.Adam.

But it doesn't change because it's about volume.Volume is always the same.Adam. So, the volume doesn't change but the quantity of gas compressed changes in the same volume area therefore increasing the ratio of gas compressed in that area. Twice as much gas compressed into the same volume would double the ratio. Link to comment Share on other sites More sharing options...

Twice as much gas compressed into the same volume would double the ratio.The CR has nothing to do with pressure. It's a ratio of volumes. Volume is simply a measure of space that can be filled with something. So the CR is a ratio of the space inside the cylinder at the bottom of the stroke to the space inside the cylinder at the top of the stroke. That's all it is.Adam.

Twice as much gas compressed into the same volume would double the ratio.No, it wouldn't. You're still going from the same start and stopping point in the volume categories, so you're compression ratio doesn't change. You still have about 464ccs of volume in each cylinder, no matter how much air (mass) you shove in there before the compression stroke. Yes, more air is in there, but its not getting compressed any more.. It's still going from 464CCs down to 54.5CCs, or 8.5:1. Link to comment Share on other sites More sharing options...

Maybe the compression ratio is not any different but the compression is. Link to comment Share on other sites More sharing options...

So, what's the purpose of a turbo any ways if it doesn't increase the compression?Pardon me but you don't know WTH you are talking about. I may not be able to explain it satifactorily, but I know what I'm talking about. Link to comment Share on other sites More sharing options...
