RE: New JetJoe J-Junior 4lbs turbine
oh boy oh boy those poor bearings
please machine your compressor wheel and spinner nut
also change the gap between the compressor and intake , your engine runs to hot
i think the shaft is moving to the back at full throttle
you can see that at the high egt
you need atleast 2kg of preload for good performance
mine have almost 3 , because of the fast accelerating during the run on my tractor
this is not negative comment ,but positive
if you can change all those things ,your bearings will last much longer
i can easy run 250k
and with shutdown , you even hear the bearings.
oke ,goodluck with the junior
if you want help , you can email me
Regards,
Martin.
