Why do I see condensation steam even after driving for over 20 mins?

 

Coming from exhaust of course...

 

What is the outside temperature and humidity?

More than likely the steam is not from water condensed in the exhaust system, that should have evaporated well before the 20 minute mark, the steam you're seeing is simply the water which is a byproduct of combustion.

 

How do I make it stop...its driving me a little mad LOL. Weather can be unto the upper 70s. I can only see it when idling...

 

Short of not starting your engine you cannot make it stop; condensation is a byproduct of combustion.

 

I know it sounds silly, but I’ve noticed the exact same thing the last few days. My ‘12 TL at a stoplight is usually the only vehicle that has a cloud of exhaust steam flowing out of the tailpipes in the morning. I don’t get it. Literally no other cars will show exhaust steam except mine. Weird.

 

Had your car recently been started? The thing is, the more recently a car was started combined with the colder the outside air, the higher the likelihood you'll see steam coming from the exhaust pipes.

 

what's the humidity level outside?

 

Lots of variables. Obviously there's the initial condensation for a while after the car is started. If there is a significant amount of water in the mufflers that has gathered, it could take longer for it all to evaporate out due to heat. I didn't think about humidity, but that could be a factor too. Also, for some reason, I've noticed that higher performance vehicles seem to show more condensation for longer, if not indefinitely. I wonder if compression ratio has something to do with it. Hotter combustion = more condensate? Either way, as long as it's steam that quickly disperses, and it doesn't smell sweet (coolant leaking) then you're fine. Mine produces steam the entire way to work (about 35 minutes). It's not excessive though.

 

Assuming we're talking about the condensate which collects in the exhaust system and not some coolant leak in the engine, it stands to reason the larger the diameter the plumbing is in the exhaust, and the more piping used (i.e. single exhaust, quasi-dual exhaust, or full dual exhaust) the greater and/or longer duration of visible condensation coming out of the exhaust pipes.

 

^that makes a lot of sense

 

excessive steam makes the car faster too

 

An extrapolation of Newton's Third Law?

 

Why are we ruling this out

 

I'm kind of thinking that is an entirely separate discussion.

 

Well, why don't we wait about a week then see if he's overheating.

 

I remember one time on acurazine, some one matched my sarcasm and told me their car and house blewup trying to modify the car. even posted pics of the house on fire.
I felt so bad. until I realized it was a joke. LOL

 

Car AND house? Damn It would have to be a joke. There's nothing I can think of that would cause that. Maybe putting C4 in the tank.....

 

the discussion was baking headlights in the oven.

 

NOS goes IN the tank right???!?
