Nuova Simonelli Oscar 2 thermal stability & MODS [CHECK VIDEO NOTES]

Full description (at greek language): https://www.greekespresso.gr/forum/viewtopic.php?f=5&t=7120 MODS: 3.2mm gigler at hot side of group, 3.0mm gigler at cold side, OPV at 8bar, water flow restrictor (ruby jet 0,6mm from Synesso machine), QuickMill Pulser to reduce noise, removed 0,7mm restrictor from pump, removed machine delay when pressing brew button (When machine is off, keep pressing double espresso button and then turn on the machine from the red switch. You can enable the machine delay by the same way). I inserted K-type thermocouple into basket and that's why you may see some water leaking. Temp during 40sec extraction started at 93 degrees celcius and finished at 94. (Add about 1.5 degrees at temp you see because thermometre at boiling water shows 98,5 and not 100). https://youtu.be/iGN45t1YC0Y Machine left idle about 10mins from previous coffee, added coffee at basket, flush about 3-4 seconds when steam stops ejecting from group, added thermocouple into basket, locked pf at group and left it about 20sec to recovery. Then brew. If you leave pf at group for 10sec for recovery and not 20sec you may have 92-93 degrees and not 93-94.
