Denny,
I took my car for a test drive today after removing the RB ram air scoop. My air temps where the same as before 4~6 degrees higher than the ambient temperature (ambient temp was 92 degrees). Look at the picture and notice where I set the temperature probe. Keep in mind that I made a heat shield box around the air filter/intake tube and a RB front bumper (bigger grille).
Also, here are the engine bay temps I got while at idle: 142 degrees AC OFF
147 degrees AC ON
Once the car start it rolling the temps dropped to 4~6 degrees above ambient temp right at the 25 mph point. They stayed the same from 25 mph to 85 mph.

Denny,
Be careful making or adding an enclosed CAI to your setup. I did a while back experimenting with a four inch PVC pipe from the intake to the RB scoop (I had to heat bend the pipe in order to molded in the shape of an oval in order to fit the scoop). Anyway, my A/F ratio jumped to 15~16 at full throttle. Thank goodness for my car meth addiction or goodbye apex.

My engine temps are down…way down since I remove the RB ram air scoop. I also changed my OEM water pump for a high flow Mazmart water pump and did the OD 160 degrees thermostat mod.
Oops! I almost forgot. I also added a 24-inch coolant radiator (rail style) to the bottom front in series with one of the leftover Pettit heat exchanger I had (located behind the aluminum intercooler heat exchanger and 10 inch electric fan). See pixs below.
At 92 degrees ambient temp and 80 mph the engine temp was 194 degrees with the AC at full blast. Once I lower the engine load and at short idle my engine temp hovered around the 180 degrees mark. Notice the drop in engine temperature soon after I let off the throttle.

Cos my regular runs (with no frenetic driving) have the coolant temp at 195-210. And thats in the clearly not hot UK....

Mazda considers 210 degrees to be normal but honestly 210 is 10 to 15 degrees too hot to be normal. Now what's "normal" for you car will depend on mods and clearly an FI application will run warmer.
As for oil...beyond 220 degrees you start to degrade your oil faster than normal if you run for extended periods of time.
At 230 degrees you better start taking notice of what your doing and decide whether to keep pushing your motor.
230 - 255 is a danger zone...at 260ish degrees you're taking the bus.

BTW, I'm using 10w40 synthetic. I also have higher OMP rates and the synthetic burns just as well as the regular stuff.

Until next year - this is going to be annual problem. I would hate to park this car for the summer but that may be the only way I can keep it under 230 degrees.
