Miata turbo running extremly hot.
 

Hey guys, i'm just done building a turbo setup, it's off the dyno and runs and pulls great.

But I have a serious overheat problem.

The Car is equipped with the following :

BEGI Reroute, Yonaka 2inch radiator with 2 fans.

I had overheating problem yesterday because i had prestone leaks, I fixed those up, everything is really tight now, nothing leaks.

I went back on the road, to test it and see how it was going, after only 5 minutes of pushing it a bit, the ECU (MS reading) sensor was showing 105 celcius and still climbing, so I went back home.

The gauge sensor is brand new (was broken), and it was showing between 11:00 and 12:00 even when the MS said 105 celcius.

I did notice a new problem, out of my 2 fans, only one is working, the one on the driver side. Could only 1 fan out of 2 be making the engine goes that hot that quick ?

What could be the cause ? It's climbing toward 100 slowly (not spiking).

Thank you

Tell me where your plastic undertray is

did you properly burp the system after fixing the leaks? Air pockets will shoot temps up faster than anything.
