Is it the cold weather?

For what it's worth, I raced a C5 hardtop from a roll a couple of
days ago. 25-80, he won by about 2 car lenghts. I was really surprised I stayed so close.
I have a stock S2000. I also had a 220lb passanger, so did the C5.
If that C5 pulled on Wes's car THAT strong, it would have DESTROYED the C5 I raced a couple of days ago.

---------------------------------------
wouldn't think that the perf of the stook is more dramatically improved than the performance of the LS1 is by the drop in temps. I'm open to some scientific or mathematical reasoning why it would be though.
---------------------------------------
The reason for this could be exactly the same as why Turbos run so much better in 'cold' air. S2000 needs a lot more air than any other car .... afterall, at 9,000rpm it needs 50% more air then it would need at 6,000rpm. So, just following this through - S2000 really needs to 'suck' air well in order to perfrom well at those revs. If the air is not good and there's not any form of forced-induction, then there is not going to be much power-increase in those extra 3,000rpm. ie. If it's running out of air (or 'quality' air) at 6,000rpm, then how is it going to have extra power at 9,000rpm?
I'd compare S2000 to an athlete who is lacking air - he could run faster if he had more air. In the same sence if the S2000 is is already having 'breathing porblems' at 6,000rpm (ie. bad air) then how is it ment to deliver any significant power gains at 9,000rpm?
Then, I have no proof or have not read some 'sience journal' with this ... just trying to apply some logic.

I think there is some truth to the fact that the S2000 may like the cold weather more than most cars. Heck I know my car does. I can beat SN95 Mustang GTs now. Back in the summer they could pull on me.
It might have to do to the fact that the DOHC Vtecs from Honda have a really high compression ratio, which involves air, which might explain this. Am I making any sense?
All I know is that in the summer I was running 15.4 in the summer, ran 15.0 in the fall and now look at my sig.
This was done with I/H/E only, temperature was 40 degrees.

Just my $.04 (inflation) worth...
I do think these Hondas are more affected by warm weather than other cars. My basis of comparison is the following:
'97 Prelude
'99 328i
'01 S2000
'01 525i
All manual (yeah, baby!)
I remember when the weather got hot, my Prelude would feel like it had HALF the power. Seriously. I had to let it cool down in the garage just to bring the thing back to life. (Not that it ever overheated, it just got sluggish) I had the dealer check the MAP sensor and everything, they said it was fine. CIA? Damn, that thing needs an intercooler. I didn't have anything for cold air, it was leased so I didn't mess with it.
The S2000 is not as bad, but you defintely feel the difference. I guess it's because they are so closely tuned. I know the typical numbers, i.e. -1 hp for each +1 degree (or whatever), but maybe some engines feel it more than others.
Now the bimmers, by comparison, were never affected so much by the weather. Affected at all? Sure, but not that badly. I DO know, thanks to a nasty accident, that BMW is very careful about where they put the air intakes. On the 525, the tubing goes down the side of the engine to open up just in the lower right hand corner of the front fender. It's next to the functional brake cooling ducts. I was so impressed I couldn't believe it.
Two notes. 1, the Prelude's intake is right at the top of the engine, left side, suckin in all that hot air. That probably contributes to the affect.
2, I remember one time I drove the car at night, it was about 80 degrees, when I left it for a few hours. The ambient temp dropped to about 50, and the engine had cooled a bit (but was still warm). When I got in it to drive it again, I felt like the HP had DOUBLED! I pressed on the gas and was thrown back into my seat. It kept this up until the engine got hot (normal operating temp) and then it returned to normal. I wonder what a dyno would have said, and what the hell happened...
