OK, so every summer, when it gets above 90 degrees outside my car feels like it only has 90hp. at night and on cool days it feels fine, and it never gets over the same spot on the heat gage .... I think it just hates hot wheather and the clutch fan is pulling alot of HP .... Am I right? or is something goofy? :dunno

i wouldnt say there is much you can do that would be worth your while. most cars dont seem to move out so quick when hot weather is outside. its a common thing for cars to feel better or faster in the cold or night when the sun isnt beating them down. i guess just drive normal during the day dont beat on it.

well if your turbo charged, I's suggest radiator, FMIC, high flow air filter.
I'm getting a radiator for the summer.

It has less power because the engine is getting hotter, less dense air. There's not much you can do about it. :(

An N/A KA that feels like crap on a hot day? I don't call that normal at all. My turbo CA feels great even on hot days and holds good temps (160^f). I do, however, have a non stock (but not performance) radiator and Nismo thermo, but that is really not enough to do squat.

Cold air is more dense than the warm air. So its not really its slower in the summer, as its faster in the winter. Any lower hp car feels this way. I felt it for almost 5 years with the N/A motor.

Correct. But our cars are not carb'ed and his is NA. Should not be that noticeable of an issue. Honestly, this is the first I have ever heard of a modern EFI car having major issues in the heat. All of my NA EFI cars that I have had have never had that much of an issue. But yes, simple physics shows that air density is greater in the cold and thereby allowing the motor to get a greater charge of more dense air in winter. About the only time that I notice is when I start up in the summer the cold start map makes me run a little more rough than in the winter, but that is it.

solution,lol
get an N-Tercooler for your car, or that ZEX intake sprayer

:D

intercooler for an N/A KA?

It's one of those functional ric0r interkool3r filter mods.

It's an air filter, but looks like a fmic. I saw it on a civic once. I suppose most people buy the "bov noise maker" and install it at the same time. :rolleyes

but of course, it adds like 300 horse power on 400psi,lol

i would try something simple to try and buy some wetter water and any kind of cooling chemical that will make ur coolant flow more colder that u can pick up at any parts store. My 240 does that sometimes as well when i drive it for a long time it feels like it doesnt have alot of power. Or if that doesnt work you should buy some ice and throw it at the motor

not sure what you mean by "wetter" water...

as for colder coolant: Purple Ice by royal purple

please dont put ice on your motor, rapid temp changes causes metal to break.

and as long as the temp gauge in you cluster remains somehwere in the middle it will not affect performance.

werd... thats just a horrible idea...


also i think what he means by water wetter is an additive made by redline that lowers the temp of the coolant.. i have never used it but some people swear by it...

Be EXTREMELY careful when mixing Water Wetter. Onezfast popped the head gasket on his old single cam civic motor mixing that crap wrong :p

Shit causes the water to get really oily then all the sudden white smoke came pooring out the exhaust and it wouldnt rev for shit. took it to a shop (didnt no any better at the time) guys told us the head gasket was gone and the head had warped a little :D

a good mixture for water wetter, is distilled water + 1 bottle water wetter + about 1/4 to 1/2 gal of antifeeze. works great, and no popping headgaskets...lol
