It has been windy though. Maybe the WA helped me maintain status quo. We'll see...

I've had the same problems in Kansas City.
I drive to the airport against the wind, then back home against the wind.
I set up a warm-air intake for frigid outside temps and it warms up outside -- creating a HOT air intake (140F = not good). Then it rains like crazy! At least this time, the WAI is a good, solid attachment.
According to the SG, I should be getting 33-34, but I end up with 31-ish at the pump. Ugh.
I need to set up a variable intake temperature system of some sort (talked about it for a long time). As it gets warmer, I'll have to move the source from the exhaust header to somewhere else or the engine will ping itself to oblivion.
That has been the hardest part about this car -- finding cold air (for both the engine and cabin). The cowling next to the battery has a removable partition that might be a good source of cool air. I may affix some sort of scoop to direct air to the airbox. It'll take a hit in aero, but I predict that the correct IAT will outweight it.
The "Vent" setting for the cabin draws air basically from the engine compartment (the hood sweeps over the vent intake and sucks hot air most of the time -- good for Winter, really bad for Summer). Avoidance of the A/C definitely will outweigh any scoop aero. We'll see what develops...
