Do Chims go faster in winter?

Do Chims go faster when it's cold?

Air is cooler, more dense. More air means more O2 to burn, therefore engine can inject more fuel and you get a bigger bang. Bigger bangs mean bigger grins.

So the weather acts like one big intercooler.

Do you think it makes much difference?

If your 0-60 time is noticeably less then I guess you have answered your question!

[DustyC]

or is it just becasue you are bloody freezing and trying to get to the pub earlier?!

Hi David,

depends on how hard you drive.
I guess its like the difference in the quality of Petrol.. Different people notice greater or lesser effect.

My high boost Nissan 200 used to run noticably better in colder damper weather. Sadly in that weather the car had no grip so any benefit was lost.

cheers,

I think Turbo cars go better in the cold.

Jet engines are similar.

In the last few months of Concorde operations in 2003, they were flying from Heathrow with full loads. During hot weather performance drops, and usually a few less passengers means you could put a bit more fuel on board, so no real problems there.

With a really hot spell in 2003, and full loads, a couple of Concorde flights stopped in Greenland for a refuel. In cooler weather, the take off performance would have been better.

So jet engines do work better in the cold, so a turbo (turbine) would in theory work better aswell. I guess a N/A might work better aswell, but with less grip, salty roads etc at this time of year, I would not be inclined to try it in the Chimaera.

My sons Scooby is noticeably quicker in cold weather but that has a turbo

Can't really tell in the Chim as I can never get the power down....every time I go out the roads are damp or wet

Not as much difference as having a fat passenger.

Don't forget denser air = more drag.

It depends on Air pressure as well as temp...

I suspect any improvement in speed from power gains are more than wiped out by the significant reduction in grip at this time of year.

Can't say I've noticed to be honest. My old Leon Cupra R suffered noticably but again that was a turbo'd engine and the intercoolers were just not up to the task, especially as it was running slightly higher than normal boost.
As said though as the roads are greasy, right foot has to be kept in check a bit more this time of year so probably no!

Only into hedges!

Cars generally produce more power in colder weather, the reduced grip makes them feel even more powerful. I reckon a good cold day is worth a subjective 100 bhp compared to a dry day in the summer.
