I'm one of those troublemakers like Frank so.....

What Frank was saying is that you did A LOT of work for a practicly unmeasurable gain. He even 'splained why it is the case. That being so, I will admitt that flush headlights certainly do look more aero.

Now moving on to your engine breathing work. What you say makes complete sense....downwind of the spark plugs. Upwind.....not so much. Infact the work you did likely resulted in at least cancelling the miniscule headlight gains.

I realize that all this sounds counterintuitive. I mean, better breathing engines are more efficient, right?

All you have to do is examine how a gasoline ICE works. It's got this pesky device in there called a throttle. Guess what that throttle does when you go through the trouble of making it breath better?

Yup, it closes a bit. Just to be an a-hole.
