We've been having upper 80s temps here in Seattle. First time I've been driving the car in hot weather.

Forget the grill issue (haha), but do you guys notice anything with regards to performance when the temp goes up? The car feels weaker in 1st, 2nd, especially under VTEC.

Also, the car feels much smoother (hot or cold temps). I have 2500 miles now.

You call it's hot when it's 80...In the summer, there would be so much more hot air under the hood. So if your air filter sucks in any of those hot air, that would definitely affect the car performance.

It'll turn your car into a slug, Space Needle. If that's not bad enough, turn on your AC and worry about the garbage truck which wants to race your S2000.

There's only one answer. Rick Hesel's Liquid Oxygen Extreme Cold Air Intake Upgrade. Yes, your car will fume like a Space Shuttle on the pad, but in addition to supercooling the intake charge, it will bleed 100% O2 into your intake manifold. Of course there is a non-trivial chance that use of the LOECAIU will turn your beloved car into a bright white fireball, and blow pieces of your S2000 (and driver) into the lower troposphere. But, and think about it boys and girls, you will not suffer from those dog day low acceleration blues in any case. One way or another, it's a case of color me gone.

Damn, 2x6spds, we agreed that you wouldn't leak any information about our new Liquid Oxygen Extreme Cold Air Intake Upgrade until we had finished testing on Greg Stevens car. We're still working the kinks out. The prototype launched the his S2000 right over that garbage truck!

All NA engines have less power in warmer weather just because the air is less dense. It seems this car is especially affected, some of it said to be timing adjustments by the ECU in response to higher temperatures.

When temps here in Texas go well over 100F the car is noticeably slower. S2000 speeds at the end on the straight at TWS are 10mph lower in the summer than in the winter.

Cdelena, thanks for answering the question.

Chris,

Is this true only for NA engines?

I don't remember any studies but forced induction engines create their own intake density, so I would guess that any difference would be masked very well.

Hi all

I think any forced induction engine's performance would suffer as the temp rises, it just won't be as noticeable because you have so much more power. A liquid/air intercooler would help a Forced Induction engine. Why? Because the little paddles inside the hairblower thingie have a denser charge to compress.

That's my story.
