During the summer, I almost never get below 32. For the 1st time this winter, I dipped into the high 20's. It's been the coldest Dec. on record here in Ohio. Just before Thanksgiving it got cold, and stayed cold. The past 10 days have been single digits to high teens.
The lake, (Erie) is starting to freeze. I'm lucky to have a lake front home, and I've never seen it freeze this early. Mid. Jan is more the norm.
What are you gettng for mpg this time of the year?

I lost about 3.5 mpg. Its been exceptionally cold here and a 4" intake gobbin' up air doesnt help that much. Part of it is also with the much colder air and with the supercharger its been a rather spunky ride and....well....just whom am I to say no to a car wanting to run. When its warmer (in the 50's or better) fuel mileage is about normal.
BOOST!!!! Its whats for dinner.
Ive had dillusions of building some type of heater for the air intake so I can warm up the intake charge on the colder days. I am skeptical of the total effect of oxygenated fuels on mileage, but without any signs or notices when the gas stations switch to it or off of it Im gonna keep my blame on the mileage hits in the winter due to the colder air.
I think what I need to do is hook up my scan tool on a cold cold day and drive and see what the air flow rate is. You can measure the flow and density to some degree (which we already know its denser in winter) and log the information and then do the same in the summer. I can also see how long the injectors are opening up for so it would be interesting to see the relationship between those two and if its linear or dynamic.
Anyway, enough rambling. I need to stop thinking out loud, Im gonna get in trouble.
