Heat soak is a bitch, but I still wouldn't trade the improved HP in cold weather for being able to drive the S 365 days out of the year (most of it top down too).

Yeah I live in FL now and it feels much slower here than it does when I am in NY. Very hot here and super humid. When I drove back to NY in the summer even it felt much faster there than in the 95-100 degree days with very high humidity.
Turbo cars it feels like a massive difference I think.

This effect (colder = more HP) is more pronounced in the s2000 because of the way the ECU manages things. It goes "conservative" in warmer weather, which makes the HP loss even more noticable.

Ahhhh yes.... cold weather.... drove Buick powered "hair dryer" cars for years... Buick Grand Nationals and an '89 Turbo Trans AM... live in Florida and couldn't wait for the "cold months" so I could take them out... night and day difference... one of the early posters was right... cold is denser so you can pack more of it into the combustion process... could even dial in two or four pounds of boost that I couldn't use in the summer... It was worth a second or more on the drag strip with the Grand Nationals... we've had a couple of cool nights in Florida lately and I noticed the difference immediately in the s2k and in the IS350 as well... sigh, this is the only time of year I miss my old turbo cars...

If I got a job offer in hawaii, I would take it in an instant! Shoveling snow, no s2000 in winter, and ice are a real pain in the northeast.

Perhaps more acurate to say your motor likes cold air. High compression cars are programed to pull out timing in hot weather to prevent preignition. The computer is allowing more timing advance with cold intake temps and the denser air is read by the mass air meter to increase injector pulse width. More air/fuel (and power).
