Yeah thats what I figured. Its quite a bit of difference in price to get the s475 with the 1.10 a/r and the .83 inducer. This is supposed to be the upgrade but drops the HP to 950. I did figure that the smaller inducer would spool faster! Just the race housing is an additional $300
Supposed to come out of the box with the 1.32 a/r and the .96 inducer.
