I do not remember them saying they logged intake temps. However 10-15 pulls at 17-20 psi creates lots and lots of heat. We have melted items around the turbine before. We now have wrapped headers and ceramic coated + wrapped crossover and downpipe.
Also, if I ever get some pics up you will see the hot side is located less than 1 inch under where the charge pipe enters the throttle body. The turbo boot controls this heat very well but we did not have it on before they departed.
