Sick of losing fuel to cold weather!

[RaceThisLTZ]

So ever since this winter cold snap, the teens and single digit temps have made my gas milage suffer by 5 to 6 mpg. Who knew i would ever be upset ONLY getting 38 MPG haha. Im frusterated with this so i have an idea that I would like to run by you guys. I plan to make a front shutter to block most if not all of the lower air duct.

My thinking on this is simple, this will let the car warm up faster to get out of closed loop faster. Keep the car running a little bit warmer and IATs will rise due to lack of air flow to the front mount. The warmer conditions and air will be less dence and require less fuel to get a complete burn. I have some extra dry carbon fiber i can use and i would fab a way to mount it to the lower grill.

Everything makes sence on paper unless somone can think of somthing im overlooking. Construtive critisim is welcome.

I agree with ur statement I'm having a hard time getting 30mpg. But last night was -1 and it ran like a animal

denser air requires more fuel to mix properly. get an Injen and enjoy the MPG.

PLease Explain? Im lost on how a CAI will help......

Injen mega rams run warmer then other intakes
Warm air= eco

 

[Eric Smit]

the Injen is certainly not a cold air intake.

My sonic got 34-36 in the summer and now I can hardly hit 30 so its normal I guess

 

[Ms.DannyStone]

Eric going 85 to 90 on the highway is not fast.. 70 is 2 slow for me lol

haha well this thread is dead....good talk guys......

U killed it. Wwwwwwhhhhhyyyyyyy

Frictional losses are also responsible for excessive fuel consumption in cold weather. The cold engine oil, transmission fluids, differential lube, wheel bearing grease; all contribute to increased resistance, thus increased fuel consumption. Also the loss of tire pressure due to drops in the ambient temperature contribute to excessive fuel usage unless the pressures are frequently checked and adjusted.
You are on the right track with the air/fuel theory, but there is more to this issue.
