Hi John,Hi Fabio, yes if my calculations are correct, the 0.005" difference in deck height would have resulted in 0.8 cc additional volume in the left bank combustion chamber, so not enough to change the compression too much.
I'm always on the lookout for things like this, because the left bank of this engine always ran a little cooler than the right bank, and I've been looking for the source of this. The AFR's were the same on both, and the throttles were well synchronised, and the STFT's were very close also. Perhaps there is some cat converter plugging on the right bank, which I'll need to investigate.....
The new liners are machined:
Nice the new cylinder liners, what is the material Steel or spheroidal cast iron?
I suppose that you don't do any surface treatment on the inside cylinder liners ....
Also i have supposed that on my 575M the left and right bank worked at different temperature, i installed two K thermocouples just before the two CAt and i checked the incredible little difference maximum of 20 °C driving slow and 5°C on full throttle acceleration !!!
