Turbo compressor spinning faster = Hotter compressed air ?
I know that compressing air heat it no matter, but there's got to be a difference between one turbo to another with regard to how hot is its compressed air.
Take one example is the Garret GT35 series. For this turbo to make 15 psi on an LS1 it would have to be spinning close to 100k rpm. Take GT42 and have it running 15 psi, it would be spinning at about 70k rpm. Would this make a difference in how hot is the compressed air?

If you look at the compressor maps for both turbos, you'll see the efficiency difference at those levels....much less heat created by the larger turbo if it is in the sweet spot on the curve.
