Yes mate, thats all the correct ballparks

But one thing to note of course is that although it will do 3 bar of boost, it will only do it at around 500-600 bhp not at full power.

So would be great for a massive amount of midrange torque (like madrod had with 666lbft on pretty much that turbo IIRC) but not great for trying to hold the boost right up to the top of the rev range, at the top end it only wants to be doing 2-2.5 bar
