Just the other night my wife came home and asked if I had ever noticed how much better our S2K seems to run when the temperature and humidity are lower. To me the car feels like a better driver all the way around including shifting.

My '97 Camaro SS was also sluggish during high temps and humidity, and rode like a wagon on real cold days. I have six old Mopars and ditto for them as well.

 

With all the aftermarket stuff being developed for the S2000, it's hard to believe that no one has come out with an air-to-air intercooler set-up for the car. The performance drops off dramatically above 80 F, and a good intercooler (essentially a small air-to-air radiator) would work wonders. We're all screwing around with $1,500 exhaust systems to get 5 hp, when an intercooler system would be half (or less) the cost and deliver 5X the power increase under hot ambient temperatures.
Plenty of room under the S2000 hood for an intercooler, and an aluminum unit would only weigh a couple of pounds.
Anyone know of a unit under development??

An intercooler cools by taking the heat from air and transferring it to the outside. The problem is that is the air outside is 90 degrees and the air your taking in is 90 degrees, there is no room to cool the air. Its only beneficial in FI apps.

the intercooler is to cool the air after it's been compressed by the SC; compressing the air heats it up.

As the air comes into the airbox it is heated more by passing by the radiator. Some others on the forum have measured temps as high as 30-40 degrees or more higher than ambient under the hood The intercooler could get rid of a high percentage of heat that is added as the ambient air goes thru the system. You are correct though - an air to air intercooler won't cool any lower than ambient outside air.

Comptech has an intercooler on the drawing board, but last I heard, it's on the back-burner while they pursue other things.

The problem with this is that the measurements were taken when stopped. That means the air was sitting there having time to heat. You can't honestly believe that air traveling at what, at least 20 mph when the engine is at 9k, is even being affected by the temperature of it's surroundings.

What would be the only solution and is impossible is to cool the air below the outside ambient temp. You'd think if there was a way, that it would have been done already.

 

hmm I wonder how a water injection system would work for our cars.. since the motor is such a high compression I bet It would do wonders ... only thing is are those systems reliable? .... I'm willing to try .. it worked good on my turbo prelude... until the car blew up.. anyways... let me know what you guys think about it
