So today I put a thermometer sensor in my air intake right before the throttle body. I did this to see how much my hot air intake affects the temperature. The thermometer is just you basic indoor/ outdoor digital thermometer. Today was 55F and raining. When I was crusing at 40mph the air temp was 95 to 105. It was higher in stop and go conditions (temps went up to 134).
2008 EPA adjusted:
Distance traveled by bicycle in 2007= 1,830ish miles
Average commute speed=25mph (yes, that's in a car)
Where's your air come from? Often the header sucks because the air through the radiator keeps it pretty cool, you need to block that air or make sure you're drawing from behind the header.
That's where I'm at. I'm getting some decent temps: 120 up to 160 in stop-n-go with some recent mods, but out on the highway it goes down -- I definitely need to block off the flow. I honestly I don't see it overheating being blocked, the heat could escape through hood gaps -- if it becomes a problem, then I envision a vacuum or electric operated duct to open and let cool in, or to relocate the rad.
I can't believe how much my car hates warm air. A couple weeks back I tried a little warmer air by flipping around the Civic snorkel thing so it sucks air from behind the radiator instead of behind the headlight. I have about half the radiator blocked (guage reads exactly the same as before), but the air can't be very hot.
Anyway, it worked fine during cold weather, but when it gets over 70 it'll ping like crazy at high throttle settings. Doesn't matter the RPM. I flipped it back and it works fine again. This is a dead stock D16z6, and I checked the timing not long ago. I'm glad I tried the free/simple path before something more elaborate.
hm the scangauge reports airintake temp but i still don't have a use for it besides monitering how hot my 12 volt battery will be. If it gets too hold I"d consider turning the thermostat to "hot" so that the engine can cool off and vice versa when trying to warm it up.
But I notice, the cooler the air... more power! but how it affects mileage it sucks.
If your reading this, then good for you, your saving some gas because your here.
