I break-in and tested last week. Here is a picture of the internal. (Used Break-in fuel)
Everything went really well and fitting was perfect. The breaking in process was easy never too tight but good thing that the pinch stayed consistance( slowly getting less tight) for long time after 5 tanks so I am sure this P/S will last a Long time.

We run 25%, i added 0.2, total approx 0.5 head shim using plug 7

Performace really good. Piston is still little tight still but the torque already one of the best I tried. I also used the WCE Clutch. The clutch was easy to adjust (advise to follow the instruction intitially, I tried without it, thought I knew everything...) and the condition remained the same throughout 3 litres which is one of the most important for me. I tested the Red and yellow shoe but condition was different, and I liked the Red better.
Pinions also show no sign of wear after 3 litres.

I tested few different pipe included Sirio 2611(07 version), Nova and some other pipes. Overall I liked the 2602 from max. Not tried the new Pipe 2648 hope to test( arrive next week).

tested the glow plugs, check them out, really fire up things when you compare to other brand.

Will be testing the 3.5cc in 2 weeks time when 1/8 seasons starts here.
