anyone else noticed there motor running a lot faster now that it has gotten colder? My question is why doesnt it run like this all the time? :grin:

hot air is less dence. that means less air can be crammed into your cylender. However temps upsally only effect turboed motors.

half right. as you say cool air is more dense, i.e richer in oxygen. more oxygen = bigger bang. nothing to do with cramming air into cylinders :laugh:

Know what you mean my car goes much faster when it gets cold! Kinda sucks dont it, cold weather, car goes like stink in all the ice and frost when struggling for grip anyway! On the bright side though my heater has packed up so although im cold i get there faster! :smiley:

I was thinking the exact same thing this morning when taking the kids to school ,(and yes I do know the reason for it :rolleyes: )but the car was going so well I was thinking it might be about to blow-up :laugh:
It'd be intereasting to put it( or any car) on a rolling road to see the difference in BHP/Torque on a cold winters day compared to a hot summers day :undecided:

In terms of oil temperature at what sort of temp do u all start to put ur foot down, in a morning i dnt really have time to let it sit and warm up, although i do for a little bit. But when i set off to work it usualy takes about 5 mins of me driving like i am driving on eggshells and taking it to about 2k rpm at the most, but when it gets to 50 degrees C i can put my foot down a bit more!
is anyone else doing the same or do u let it get warmer first?

My chargers chirpin like a b!tch now! an i normally run my car for 15mins before using it

I always keep mine below 3 - 3.5k until its up to 80 degrees...even then I dont really give it any til its nearer 90..
-
i keep it nice and easy till it warms up properly, around 70 normally. mind you it'd take that long before you get out of traffic anyway!!
and as for the cold air affecting rolling road figures.... with any luck we'll all be happy after the 26th!!
-
think i will let my valver get a bit warmer before i put my foot down, like 70-ish then!
but its usually just on the way to work and there isnt enough time to get about 3.5k rpm anyway!
