Out of interest, are Turbo's still efficient at these high boost levels?

Following on from what Gareth said, if you look at a compressor map for a turbo, the 'island' in the middle is meant to be the area of highest efficiency. So depending on the turbo, it will depend if the boost pressure you are looking at is in or close to the island. The further away you move the less efficient it becomes.
I would imagine as a very general rule of thumb, if you use bigger and bigger turbos the pressure for optimum efficiency gets higher, coz that is why they are big so they can work at higher boosts and air flow efficiently.

i dont kjnow to be honest,,, i didnt look into it that much
when spec'ing a turbo for an application you can do all the calculations you want and platting on different compressor maps but the only true way of spec'ing a turbo is trial and error
