Insulating Engine

locutus,

There was a VERY in depth discuss a while back on IC titled :
Tire, Aero & other resistance vs. MPG (HIGHLY technical)

The result is basicly Rolling resistance is a big factor and goes up faster in cold weather than aerodynamics does... But both increase in cold weather the same time the Engine gives out less.... RR is the larger force for most cars up to about 40 MPH... In cold weather even the Aerodynamic Insight with Low RR Tires the RR is larger effective counter force than Aerodynamics up to about 50 to 60 MPH...

Go over to IC if you want to read the whole thing....

highwater,

yes that does sound more like what I was thinking of... but no small task and lots to concider.... I think you are further ahead in the concidering department then I am at this point....

Mike,

I am no where near a test system for this winter.... maybe next year....

General,

I agree... the inishg talready has RR tires... already very Aerodynamic.... engin heta is all that lef for us to focus on.

I found it on IC. *Very* informative, thank you!

Hi guys. I'm keen on lagging my engine bay too but lately i've had to replace all the ignition coils in my renault scenic (at 80 euro each!). Turns out they dont tolerate the heat too well, especially since they are buried in the engine, down the spark plug holes. So while insulating the engine bay is good for mpg, the coils need to be kept out as best as possible from the heat. I thought maybe tying on some heat sinks to the tops to help remove excess heat from them. Its tight there so choices are limited.
