The weather here in Eastern Pa. has been cold (20f and below). My 1.6 turbo seems to have more power in this weather. Do you think this is the same affect an intercooler would have?

yep,Even at these temps my cooler still cools the charge by 200 f.You would think the ingested cold air would create a cold enough charge.

The Thermodynamic efficiency of all ICE are determined by the temperature differential, so colder in = more power. Aircraft are even allowed by law to carry 10% more weight in Alaska than they are certified for in the warm air of our lower 49.

So if I had an IC their would be even more power in the winter.

yah cuz it seperates the turbos heat from the charge.

My NA diesel is noticeably more powerful in the winter than in the summer.... on a 20F day, it's quite a little terror. One a 100F+ day, it's a slug -- barely pulling some hills in 2nd gear, that it would pull in 3rd gear in the winter. So, yes..... inlet air temp (either from the weather... or from having an intercooler on a turbo) does seem to make a world of different on diesels. The colder the better (once you get it started, that is....
And my gas truck has a exhaust manifold preheater, to keep the carbureator for icing up in cold weather :roll:

the performance could also be attributed to the fuel being cooler as well. theres a specific range where the fuel burns best... anyone with knowledge of TDI's know what the range is for fuel temp???
even compressing cold air will make it heat up. maybe if you can find -80C air, then it might not make too much of a difference :lol:

So once its combusted the air would be the same temp after? in a controled test(no intercooler)With an engine running cold air and one sucking hot air.I wonder what the immediate temp difference would be?I wonder if it would remain linear with the colder the air the colder the combustion.I mean could air be so cold it wouldnt combust?hmmmmmm..,..

Bmw using a system in its 330D 335D diesel engines to keep the temperature of the fuel.
They got a heater and a small fuel cooler in the engine compartment.
Everything is controlled by a computer.
Have heard that 7-10 degrees C is the most optimal temperature.

engines also run better when it's raining
