Engine has started on megasquirt but I haven't driven or tuned it yet, so I'm just a beginner.
Thanks for the advice on the size of the opening. I agree it looks a little small, I might open it up or make a hole near the headlights. I'm leaning towards the hole that is already there for the A arm access.
Not worried about it been in the wheel well, still cold air. Not worried about ram air.
I have ram air on my plane, direct straight into the throttle body, no air filter and I get +1.75 inches of mercury effect at 200 mph. So on a car it won't make a difference.
