I'm not posting in this thread anymore because everyone here tried to help by suggesting ducting, and two people denied this logic every time.

I didn't mean to be a jerk about it.
Yes, I totally agree with what you are saying about ducting and sealing the airflow path. However, in some cases there is just way too much restriction in that path for things to work properly. That is what happened in this case. Sealing, ducting, scooping did not fix the problem.
You are right, separation is not the same as a V mount provded that the V mount has a divider between the IC and radiator.
In a conventional configuration, the point of the separation is to increase airflow through the radiator core, at the expense of less airflow through the IC.
Again, I totally agree that you can't have air spilling out all over the place. Sealing and ducting is crucial. It's just that sometimes there needs to be more airflow to the radiator than what can go through the IC core.
I'm invested in this only because he is a local and a good guy. I apologize for pushing the point and will get off my high and beaten horse now.

Alright, I got the Miata back from BEGi last night. I wasn't able to overheat it on the drive home, but then again it was at night. More driving soon! It took 5-6 minutes this morning driving to work for the car to get up to operating temperature.
Thermostat was Removed
Restrictor plate was added to the front Coolant Port which was t-junctioned in to the re-route line
AC Condensor and Radiator Spaced a little further apart
Supercharger Mount Fixed
Supercharger Pulley Machined (had knicks in it)
Intercooler height cut down a couple of inches

She sprung a big leak tonight. Was driving around, parked it to meet a friend and there was white smoke, hissing, and then coolant running from underneath. After letting it cool, topping it off with 1 gallon of water and rolling her down the hill to home I found there was a stream of coolant coming out of the inlet hose to the heater core. This car is becoming a pain in the ***. It was running great all week until this.
I will be ordering a real water temp gauge tomorrow. Any suggestions?

I know, I've read your build thread. I am not taking it for granted. I was lucky I found this issue out just up the street from my apartment instead of it popping on the highway. And also that, currently, it's only a coolant leak and not a blown motor.

So I've returned from SCCA Solo Nationals in my s2000. Was a lot of fun, first time. Anyway, I got the water temp gauge installed today. FINALLY! I drove around and found some interesting readings.
3:30pm. Ambient temp in mid 90's. Cruising at 80mph
A/C is Off. 200* F - 204* F
A/C is On. Within 1-2 miles it was at 220* F and still climbing. I shut the A/C off and evacuated the heat.
8:30pm. Ambient temp is low 80's. Cruising around 65-75mph
A/C is Off. 194* F - 200* F
A/C is On. Stayed at 214* F
9:00pm. Idling in a parking lot with A/C on. Temp got to 240* F and was still climbing; I shut it off then. The stock dash gauge was still sitting at the "nominal" position (just under 12 o'clock).
