with the bearclaw cover, that is the question.
I did a little semi-scientific study to see if it intake air temp was cooler without the claw cover. And surprisingly I found that it doesn't make a bit of difference.
I have been running around for the last few weeks with the claw cover off. So I hooked up my scangauge II and went for a 25 mile ride with both city and highway riding both with and without the cover on.
It was about 90 degrees F out. I found that the intake air temp stayed between 115 and 120 degrees F, no matter whether I was going 100mph or 10mph. The sensor doesn't seem to be real time and only samples every so often. Cross winds seemed to have the biggest difference on lowering the intake temp, still it would get down to 112F only for a bit. At highway speeds it stayed at a steady 118F both with the cover on and off. City riding would vary depending on wind direction but no differences were noted whether the cover was on or off. I think the biggest spoiler of cool air reaching the intake at highway speeds is the warm air coming out of the radiator.
The coolant temp was around 198F while cruising and would get up to 216F at it's highest.
The scanguage also shows the % of load the ECU is calculating. This engine doesn't work hard at all. At just about any steady cruising speed it is in the single digits. It takes WOT for a while to get to 100%. Short blasts from say 50 to 80 mph only get up to about 60%.
So for what it's worth and from where my air temp sensor is positioned (between #1 and #2 throttle bodies) the intake air temp isn't any lower with the claw cover off.
