Took the car out last weekend in slightly humid weather, it wasn't hot though...was around 20°c. It felt like the car lost a bunch of power. How do your LT1's run when its slightly humid outside?

 

Any car will run underpowered in humid air. There is more water in the air and less oxygen. You can slightly lean the car out to help with that. You need less fuel to burn in a humid environment.

my car never really feels different, other than when it's really cold, and even then, it's not by much.

 

i agree with the 2nd post, even though im an ls1... i doesnt make a huge difference but i do notice it, but im also down in southeast texas where we sometimes chew our air before we breathe it..

 

Ya both you guys live down south. Its probably fairly dry in Florida. I just got the car 2 weeks ago. The night I took it home and drove it hard it was just an animal...it was 14°c that night and humidity was low. The car has a built 385 in it with a mild cam.

Regardless it didn't run as hard last weekend. Fuel pressure is ok, oil pressure is ok, etc. I don't know if its the Opti acting up or if Shell messed up their gas.

 

up here in the good 'ol midwest (and I mean the the real midwest, not Chicago ) it gets humid as a ****...I can definately feel a difference on some of those humid days w/my car...

 

Bro..im in Tampa Florida...and and its crazy humid right now...it gets pretty bad here. But my car does run a tad bit sluggish during humid weather...but not enough to make me worry. However, thats with the AC blarring too..otherwise i wouldnt make it during the day..even with the windows down..lol..jut too hot!

 

are those OEM c6 rims you have? or what brand. I want some for my NMB ss

 

 

 

nope, not OEM. you can get them from another site that isnt a sponser here, so i'll shoot you a PM

 

Never been to FL, I take it. You need scuba gear to go to the grocery store in the summer.

 

lol yes its hotter and more humid in flordia than almost anywhere.

 

I stood outside for 2min and started sweating. I hate this craphole. I'm moving to Canada.

 

I think you guys in the humid southern areas don't see as big a difference in temps and humidity as we do in the NE states. My car feels like a pig in the July/Aug hot/humid days, feels like it's off 25 hp some days. It runs like a raped ape in nice cool low humidity fall days. I ran the #'s below on a very low humidity 45 deg day up here. I wouldn't have come close to that in the middle of summer.

 

Agreed.
