Mocal Oil Cooler Installed

After having a small oil cooler (13 row 115mm matrix) at the side vent and seeing that it is inadequate for track duty (after 3 laps oil temperature would go as high as 125 Celsius) I decided to double the volume of the oil cooler with a Mocal 13 row 235mm matrix oil cooler.
Also, I used a thermostatic sandwich plate meaning that until 80 degrees Celsius oil will not go through the cooler, which helps especially on cold starts in the winter.

Testing of the oil temperature difference regarding the two oil coolers will happen in about a month when the Race Track in Athens will open again.

Rotrex C30-94 New Impeller

The replacement impeller for my C30-94 came in the mail today from
www.superchargerrebuild.com

Reason for this replacement is a former mechanics big mistake to use a wide washer for the return hose (recirculation) of the bov.
Due to vibration, the washer came loose and hit the impeller a few times damaging it.It was still in good working order but I went ahead and ordered a new one for added safety.

Rotrex doesn't supply any parts , so superchargerrebuilds was the only way to go.

I will replace it tomorrow and report here.

 Update: In the last pictures you can see the new impeller installed.Big thanks to Bill from PB Motorsport for helping with this.

Pretty straight-forward to swap the parts, you might need a heat gun for the input shaft for the old impeller to come off.

Be careful not to brake the input shaft or it's bye bye Rotrex. In the final picture you can see the damaged impeller.
