My car just for informational reasons is set up according to 949 racings website for a track purpose car. I do have a GV front splitter and also have cut the rear bumper pretty high up. My car is on Koni race coilovers with 700 and 450 Springs. I have the big Racing Beat sway bar on the front and I also have a Racing Beat the intake for the 1.8L.
So I was driving on the freeway and noticed my intake temperature was 104F. I thought that was pretty high considering the ambient temperature is 57F. So I open my headlights out of curiosity to see if it would change the temperature the temperature dropped down to 71F.
So I decided to do a proof positive experiment. The road I was on is very flat and straight. So I turned around put the cruise control on at 71 and turn the data logger on. I drove for 5 miles with the headlights down and record the data. Then I got off the freeway got back on and drove for 5 miles with a headlights up. Then reported that data.
So the results for the headlights down came out to 109F of a high with an average of 106F. With the headlights up the high was 71F with an average of 69F. I have removed the little flap on the hood behind the headlight. But other than that there is no modifications to the hood or the headlight. I did notice an slight increase in fuel economy also but I didn't really Datalog that so the data is not concise.
I gave the car 1 mile of equalization before data logging on each run. So each five mile section was a true representation of what the car was doing as opposed to turn around and getting back on the freeway having an effect on the experiment.
Just thought I would pass this information on. Well not an completely empirical test it does give us a pretty good idea of what the intake temperature doing in the engine bay.
Cheers!
