Turbo is fine, no worries there. Built and running plenty of them. Just not on 'fragile' tranny.
"Hot air" is generated by the compressor side. Running a compressor outside its high efficiency range (shown as efficiency lines in % on compressor maps) results in 'hot air'. At 50% efficiency, half of the input energy (the turbine is the 'motor', driving the compressor) is converted into heat, and only the other half into pressure increase. Our setup would not have any issues running WAY past the 22 psi (stock MAP) limit. I am also pretty sure the internals (Cosworth surely didn't skimp on the goodies) are quite strong. So the engine is good for plenty of torque and power. No worries there.
