Quick update here.
Mechanic refused to swap out ts to 82 from hi flow 76 citing the load with the backpack aboard. Fair point.
So, on my annual Grumpyclaus run, Warwick, Tweed Heads etc from Childers, I reckoned to really test it, albeit running empty.
Away about midday, ambient temp here high 30's. Southwest to Yarraman and then directly west toward Toowomba. Temps never over 80. Egt's steady around 350.
Up the range from Yarraman at Thornville. Ambient temp 40+, flogging it all the way 110k plus.
Finally pushed it to 92 and egt's to 550. But seriously had to flog it, fuel gauge hated me.
Upshot, still thinking higher rated TS required.
