Hey Robert - look in the archives!
Sorry, too easy a shot. ;->
I posted last year about this. As David points out,
colder air = denser air => more air into the engine => more hp.
with cold air intake thingy
: Try driving your car in the Rockies at 10,000ft and see how it doesn't perform.
: I fly aeroplanes for a living and the density of the air is a huge performance characteristic.
: i.e cold air = fast, hot air = slow.
: DF :)
: : It's still hot in Dallas (94 yesterday) but I suspect some of you are starting to enjoy the cooler fall weather. I want to plant this bug in everybodies head now and then lets revisit the issue in a month or two.
: : With my 1.9 I noticed quite a bit of difference in the performance between summer and winter. With the denser colder air the Z3 seems to pick you some extra power (at least my 1.9 did). I assume the colder, denser air is like adding a bigger air intake on your car, except this time mother nature is picking up the tab.
: : Curious if I will see the same type of performance gain for the M, and I would be interested to hear what other 1.9, 2.3, 2.8 and 3.2 owners think about mother natures free upgrade.
