Full Intake Cleaning

 Since I took the Rotrex kit apart to change the Unit's impeller, I took the time to thoroughly clean all intake parts..

 I used brake cleaner spray for the Intake Manifold and the Throttle body..The IM was in a good shape with not much gunk to clean on the inside.On the other hand the Throttle Body needed a bit more work to bring it in the immaculate state you see in the pictures. 

 I used Contact Spray(No residue) for the Supra MAF and other electrical contacts on the Throttle Body.The small wires inside the MAF were black and ended with a silver-ish finish like they're supposed to.You can see it in the zoomed picture.

 I continued with the Intercooler (Chargecooler) for my Water Intercooler setup.For this part I used gasoline.Filled the air pockets with it, shook and emptied..several times.In the last picture you can see the IACV (Idle Air Control Valve) from the TB side.I used also brake cleaner for this part.For all the silicones tubes I used soapy water and called it a day.

 Lastly you can also see the Hondata Intake Manifold Gasket for added heat dissipation between the block and the IM. 

Yokohama Advan A005 WTCC Volk Rota Wheels

I came across a good deal on a set of Yokohama Advan A005 WTCC Slicks 240/610-17.I got them from PB Motorsport in Athens.

I will run a square setup, the tires are like 245/35-17 in normal size so I will have no problem with rubbing in the rear..a slight roll in the front might be necessary.

I already had two Volk TE37 17x7.5 et40 that I will use in the front.Since Volk doesn't make a 17x9 in 4x100 bolt pattern I went with white Rota Grid et45 to match the front wheels.

The front wheel/tire combo came out at 15.1 kg, pretty impressive.

The rear combo weighed 17.1 kg which is fine,considering it is a 9 inch wheel.

In the last pictures you can see the difference of the same tire mounted on a 7.5 inch wheel and a 9 inch wheel.

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.
