Increased low end response in the rain - why ?

[Daryl Davies]

my 2000 tundra spent its first 10 years of life on the humid California coast line. It now resides on the dry Canadian prairies. The 4.7 now has headers, a cold air intake and slightly better exhausting. I swear that when it rains (high humidity ) the low end jump is crazy quick vs dry ( low humidity ) days. What?

Humid air does not compress as easily as dry. It effectively raises the combustion ratio. That's why the Air Force used to have water injection on it's B52's.

Lots of low end torque.
