Can you move intercooler to driverside more?
there wont be getting hell of lot fresh air get to radiator with intercooler being that thick dam.
Can move radiator out to passenger side more?
then pull panel from front bumper wide as possible to radiator so get funneling fresh air to radiator, even on intercooler side to slow heat from intercooler to radiator
Dividing plate in engine bay between rad and turbo to slow transfer of heat over going from block to radiator panel
if that does work get radiator flow tested, if ok, need put holes/vents in bonnet to let hot air out.
