Thanks for the feedback guys.
The temperature of the oil would remain relatively constant, because of the way we (Hypermilers) drive, with almost no WOT. As the throttle opens, the air drawn past the oil cooler would cool the oil. The oil, once it has recirculated back to the sump, would then cool the remaining oil, thus reducing the the temperature at the oil cooler, in theory, of course. The only time I would be concerned, would be in bumper-to-bumper traffic.
The problem I'm foreseeing is thermal efficiency. The gains I make with the HAI may be counteracted by the loss of heat in the engine block. I Might just have to try this and see where it gets me. (Don't worry, I'll take pics when I do
)
I live in Massachusetts, so we see the full gambit of temperatures and conditions, -30* to +110*F and every type of precipitation known to man
