Finally got the first race day behind my R3, it was so much easier to tun it compared to the engines i have had before.
Track was really tight so very low gearings have to be used. To get a decent power out of engine, i had to run it at ~110C (230F) during the qualification rounds and with the same settings, after 30min final temp was 130C (265F). In total, not more than 2 liters (1/2 gallon) of fuel have been used with this engine.
Could it really take so long to break in these engines? And can it be expected to see lower temp ranges after few more liters of fuel will go trough the engine?
