I had speed 900's in 540 with 80mm wheels on 7:1 and even without magnets the motors kept blowing...bonx is 9:1 I think and his motors still get warm with 2wd...

Satanix 1.66 uses Graupner speed 900@5S on a 6-1 gearratio to 130mm wheels.
No blowing motors.
Skyfall ran S900s on 7:1 with 120mm wheels on 6S, motors got warm, but never the TZ85s
Have you checked all your drive shafts are straight and that everything is running true? There may something that is causing lots of friction which could be messing things up.
What about a dud TZ85?
Those robots are 2wd with so gle stage spurs though so hardly any resistance to turning. At just over 5:1 and 4wd with bevel gears and belt drive I think that's the problem. To reduce the strain it might be worth really narrowing your tyres to reduce the friction when turning and see if that helps at all.
Another suggestion that Alan just mentioned (discussing it now over dinner) is to leave the tyres on the front wheels and leave the back slippy. That will give you skid steer like venom/360 etc and majorly reduce the current draw when turning.
Considering the ESC's ran Tormenta 2 fine I don't think that is the problem.
If the escs were fine previously then it's for to be the new drive... Tormenta was only 4 drill motors... Big difference!
Is there much heating when you run the bot with the wheels off the ground? if there is still heating, then the problem will be friction in the bearings, if not, then the reduction is too low. The critical thing is to find the specs on those motors.
Specs, as far as known. 18V 15 Krpm 18A nominal.
