cold weather--the ultimate performance

enhancer. I was relieved that my car started this morning despite the negative 17F temperature. Noticed that once the motor warmed up the car was definitely zippier. I read once that colder denser air was good for turbos but didn't think that applied to na cars. Also, the suspension was a good bit firmer, giving me an idea of what my 15 year old might have been like new. I guess there really is a silver lining to every cloud.

It was -20F (-29C) outside my house this morning, my car barely started with some awful rumbling engine sounds. The oil took much longer to get moving through the system than I would have liked. It'd be nice to have a block heater for this weather.

Should be near 60 F here today... Might have to wear sunscreen for our picnic lunch...

Heard it was cold enough to close schools in Michigan. Now that is COLD!

Dan,

Time to clean out the garage and park the old beast in there..

Any engine benifits from cool air, forced or naturally aspirated. The cold air being dense allows more fuel to be mixed with it, in a given space, i.e. the cylinder, whilst still keeping to the optimum fuel air ratio.

High altitude also has a negative effect do to less dense air so the denser then better. Turbo's have a positive effect by greating a hugely dense pressurised inlet charge, too which you add huge amounts of fuel and still have the right mixture ratio . . more fuel burn't is more chemical energy = more bhp. . . then you go very fast. . . .until your piston tops melt or your crank snaps in half. . .

Sorry, got a bit techie there

I was zipping along the highway at 0F last night

Lovin' the nikasil

I did notice the flip side of the increased performance. My mpgs which are normally 20-22 have fallen to 15-18.

The only vehicle in there now is my snowplow tractor. Although, it was probably a balmy -10F inside the garage instead of -20F.

yeah, they closed em, my little bro is home from school. its rediculous to close schools because of the cold, the little turds can stand outside for a little bit, if theyre stupid enough to not wear a coat then darwin says they should freeze anyway

Yeah, you don't get something for nothing in this case.

I don't work out my mpg anymore. . . i did once and it only made me feel guilty
