So a full year on and covered another 6000km (to date: all up 8200km) of testing/racing/top speed trials.
Summary: Every drive has been quite high load 90-140 testing probably around 400 or so of these tests, many 100-200kmh & 60-130mph runs (3rd to top of 4th gear) and a few top speed runs (on special test track ). Last 3000km at ~500bhp level @ 1.53kg/cm Boost level.

I did one intermediate compression test between the 1800km and this one today, but only wrote those figures down rather than taking a photo/proof. They were close to the ones today.

This test was fully dry (engine run till out of fuel) and EGI disconnected, First one cant remember but I think was not as "empty" of excess fluid, this makes a high difference to rotary engine compression readings FYI.

Anyway she is not too bad, I did not think it would hold up this good especially given its a mobile test bed each and every single time it gets driven.

I have it at its new boost level of 1.7bar (around 1.75kg/cm) and it is a rocket see if she can make another year of punishment

So here is my once annual compression check up of RICESP (3rd year now! ~20,000km covered!)... This is after using the car as my daily driver for over 6 months! and also all of the higher boost settings and reconfiguration I have done over the Christmas break
