I'm not crazy. I know I'm right, right?

The reason the Dragsters at the Baytown drag strip set so many records is because they run the big events in cool weather.

Yes, cars run better in cold air. They call this type of weather "boost weather" because forced induction cars, especially turbo cars, love the cold dense air.

As far as the racing you ask about...it's not always about optimum performance. It's more about cars competing against each other under a certain set of conditions and see who can do the best under those conditions.

In drag racing especially, you have to be able to adjust your car to track conditions and weather. It's a tricky thing.

I just got rid of my coyote mustang with a large single turbo. It was alway fast, but in the cold air it was nasty. Scary on the street.

Where is that whore?.....out sucking in cold air?

And blowing out hot?

Muffler Bearings are shot! I keep telling you!

...or...

Every year when the temp drops this crosses my mind, but then the left side & the right side of my brain start to fight, I never figure out the answer, the winter season comes to an end, & I am left wondering ... am I crazy?

Sooooo, my car runs better during the colder months, doesn't it?

I swear that puppy is much peppier & I notice it the most when I am driving very hard & very fast.

I'm thinking that the lower temps improve conditions & allow my engine to preform better ... HOWEVER ... this is where the left & right side of my brain start arguing ... because if that was indeed the case .... wouldn't NHRA & NASCAR, & really all racing in general, take place in the colder months instead of the warmer months?

I'm really confused ... so who can alleviate my upcoming winter of confusion & break this down for me? Originally Posted by Brooke Wilde

Brooke, cars perform better in the colder months. For example I have a supercharged car that runs 10.9s in the cooler months, but would run 11.2 during the warmer months. This is why I never go to the drag strip between April and October.

I agree with everything Big Lou (real world buddies) posted about performance. Both of us race our cars, so we know exactly what you're talking about. The weather (DA=density altitude) affects all cars. Forced induction or non forced induction, Ford, GM, Dodge, doesn't matter.

There are 3 types of DA. One is exact DA, which is .000, one is positive DA which is posted like 3,000, then there is negative DA which is posted as -3,000. DA can change from one minute to another dependent on temperature or humidity. The one fixed part of the DA equation is the altitude of the drag strip, which is always fixed. Can great DA be negated? Yes, if you have a DA of -200, however have a 20 mph head wind is how. Having a -400 DA, however the humidity is 90% also partially negates a great DA. Give me a sunny 45 degree day with 30% humidity, and I'm one happy camper.

Look at it like this. Take two buckets, fill one with water, one with used peanut shells, and put a quarter at the bottom of the bucket. The one with water has 100% resistance, while the one with the peanut shells has far less resistance, so the quarter would be easier to reach in the peanut shell bucket.

So yes Brooke, your car runs better right now as compared to the summer months.

These folks have way over simplified the situation for a street car.... but I'm not going to put up a bunch of information from my phone and haven't posted from my keyboard in a while.

besides, that crazy whore hasn't returned to this thread....just as i predicted.

Hint: A better scenario to explain to the street whore...no pun...is more specifically explain why, after driving the car in warm weather....then, on the first morning of a cold front, she starts up... gets on it and it feels like her engine is 20% bigger/more powerful. Then, her extra power fades away even if the temps stay low.

But... dont forget to warm it up before you romp on it
.
When your car has been sitting out overnight, all the lubricating oil that's coating all of the crucial, moving bits of the car has settled down to the bottom of the oil pan. When the temperatures are really cold, not only is that oil not near the areas it needs to be, its viscosity — ability to flow — has been severely impaired by the cold. You've seen how differently, say, refrigerated maple syrup flows compared to hot syrup — the oil is the same way.

So, when you start that cold engine, it's essentially running without lubrication. If you start up and immediately put a load on the engine, things could get damaged. It's just not ready to go. Take a minute or two to get that oil pumping around before putting any load on the engine, and your pistons and camshafts and turbos and other spinning, moving bits will be much, much happier.

You could also replace the word "engine" with "pussy" in the above text...same thing....

Somehow or another, I thought you were better than that.

Cold dense air creates more power. Originally Posted by The2Dogs

It's a fact for F-16s. Cold air is denser, so offers more bang for the buck; more stuff to push off against..

that does nothing to prove that you're not crazy, unfortunately.. Originally Posted by pxmcc
