[QUOTE="JeremyH, post: 14524642, member: 160292"] No, not that would be noticeable. When air cools and gets denser pressure does drop, but now you have more air in the same space as well as more fuel so overall theres not a net change that you would notice from the cooling of the air in the combustion chamber. My compelete system, 3.5" charge piping and big ass fmic has alot more volume to fill and I loose less than 1psi from turbos through intercooler to the intake manifold so I dont see you being able to register any boost drop from the cooling or air in the combustion chamber. You can get a denser charge two ways, add more fuel volume to the charge and add more air. The colder the air is the more dense it is. So e85 does both. When ethanol vaporizes it removes heat from everything not just the air, some ofther cooling benefits I've noticed. I have a return fuel system and on a hot day my fuel rails would be burning hot underhood, too hot to touch. With e85 they are luke warm at best now, quite suprising. Also had my fan fuse pop in stop in go traffic on a 90 degree day and the car was overheating, my water temp guage never got over 220, previous overheating situation with gasoline would peg my temp guage at 260.
