Could you have a look at the atachment please & let me know what you think?? I\'m prety sure that I have got all the figures correct in the maths, but would be nice to have a pros opinion on them ;)

Stock engine should flow: 628.4cfm @ 8000rpm running 0.9 bar (acording to the calculations this should produce about 338bhp?)
Stock engine shoul flow: 727.6cfm @ 8000rpm runningg 1.2 bar (acording to the calculations this should produce about 392bhp?)

The dark blue line  is the 0.9 bar pressure line and the light blue is 1.2bar

On the Garrett site there are some good tutorials on Turbo\'s
 
The last one is all about compressor maps :) :

It should help you size an appropriate compressor / turbo.
