Has anyone noticed with their TL's or other cars for that matter a difference when driving when it is very humid compared to when it is not. It has been very very humid almost 100% humidity here off and on for 2 months and it's like this all summer long. I notice when it is very humid my accelerater feels heavier and when I accelerate hard it's still responsive, but just a little less. Almost like if you where jobbing when it's humid you can breathe okay, but not as well when it's drier outside. Have any of you experienced this and is there anything I can do to help my car breathe better when it's humid like this?

 

yes, temperature and humidity does make a difference on the engine. there's a thread on mpg on how these factors can impact the miles we get.

 

its not just your car but all cars in general. this thick humid air is harder for a engine to turn into energy. there isnt any thing you can do.

 

I figured this was the case, but I always thought the denser the air going into IM was the more power it would create. You know like a CAI pulls in cold air which is denser and creates more power. Why is this not the case with dense humid air?

 

its the opposite with high humidity, its not cool and dense, its hot and dense with moisture.

all has to do with barometric pressure and other weather related crap.

 

yeah the moisture must be what bogs down the engine some, thanks for the insight.
