Message: [QUOTE="KCTurbos, post: 1406522, member: 13852"] First of all... As was said many pages back. Efficiency is a relative term. It means different things to different people in different scenarios. I understand what Jay was getting at, and I agree with his logic. Better atomization results in cooler egts. But... cooler egts is not always a good thing in the turbo diesel world. I personally don't try to keep my EGT's down in all scenarios. Saying lower egt's is always more efficient is wrong. When racing down the track I actually shoot for about 1500egts because that is where you are going to drive the turbo the hardest. You are not driving the turbo as hard at 1200egts. Turbos thrive off of EGTs. A Smaller A/R housing tends to run a little hotter in some scenarios? But that is by design. To more efficiently spool the turbo. VGT turbos tend to run slightly higher egts... because it is actually using the vanes to create excess pressure, which creates more heat, which spools the turbo faster. The other part of the equation is there is an "optimum" window to dump fuel. Running longer PW can create more power vs running a shorter PW with the same fuel. You need to catch the piston going back down the other side to most efficiently produce tq. Just like riding a bike and pedaling a bike. The downside is the later in the stroke you spray your fuel... the higher your egts. So... does cooler egts always = more efficient. NO... But I understand what you are saying. [/QUOTE]
