Hi All:

___The following might help: Warm Air Intake vs. Warm Engine Temp.

___A radiator block mod will not come close to Summer temperature driving FE in temps below ~ 60 degrees. A radiator block and warm air intake mod will not do it either but each adds their own component to improve FE in colder and colder external ambient temperatures. 2 more components are needed to solve the problem once and for all imho.

Stupid Puddles!

___About half way down the page of the linked thread, the discussion for the final solution comes into play. A totally sealed bay, warm fuel, warm air for the intake, and warm coolant all together in one nice package. Wheel bearing temps and such cannot be cured but they are not a huge drag imho. All of this talk about battery pack temps and such lowering FE is getting close to bunk for the Honda IMA setups in particular. Since the Prius I and II are forced to use the pack for some amount of propulsion, only a small portion of this discussion makes sense for them as well given the packs are ~ up to internal ambient in a matter of 5 minutes or so.

___Good Luck
