You can begin to answer your own questions by calculating the % increase in thrust that is to be delivered thru the rear suspension components. Based on that, you can determine what upgrades of those components would be required. You can then proceed to calculate, from the half-shaft torque number, what changes would be required in those components. And in turn, you can work your way inward and forward thru the driveline components until you reach the crankshaft.
There is no specific limit on power, however there are strength and fatigue limits of all components in the powertrain. At some point, increases in torque, even for drag racing purposes, will cause real difficulties in operating the vehicle.
