It looks like the designer of the HF on his 3.3 CIS turbo has added a larger hot side wheel from a 7006 but with a smaller AR.

This would probably lower header pressure and get the hot to cold wheels ratio back closer to what BW/KKK usally built.

It is far easier to free up the 7200 vs finding/casting a smaller A/R housing for the 7006.. It took me 4 years to get my hands on the 9cm/2 housing. With that said the 7200 does spool up quicker.
