Do you know how a Centrifugal supercharger works? Properly designed? That don't make much sense to say that when the companies that produce S/C'ers have been doing it for decades.

however im talking about the new age of supercharging. either a 6th gen eaton TVS or twin screw design. both offer adiabatic efficiency in the 70% range and some approaching 80%. they can run more boost, more efficiently. AND most modern kits have an integrated water-air intercooler.

Intercoolers add thermal efficiency but it's not a deciding factor between a S/C'ers efficiency compared to a turbo's efficiency.

AMAZING kits from lysholm, whipple, magnuson, vortech VTS, roush, edelbrock, kennebell, etc... again, not to say there are no turbo domestics, but if you want FI the common route is SC over turbo. for imports its turbo over SC.

Thanks for confirming what I already wrote. If it's a V8 then the difference is minor from S/C to turbo on the same applications. Everything you listed was American Muscle V8's. They are not Import Motors.

Still not true

Bro, Minimal lag is basically nonexistant. I'm talking "Not noticeable" minimal lag. And lag in a turbo is still more efficient than the Centrifugal S/C design. And the Torque curve of a turbo depends on the turbo. You can change the curve simply by changing the turbine size. Not all S/C'ers produce a flat torque curve just like not all turbo sizes create a flat curve. You shouldn't generalize in that fashion because of a little thing called tuning.

Power is not included into subject of Efficiency.

My only concern is the offset, but I suspect they will be Subaru offsets (Between +48 and +55)

I'd take them too. But there is a reason why those wheels cost more money. Design is part of the equation. Albeit you do pay for a name as well.

Like I said, I'm going to be running a set of 18x10 XXR's on the tC and XXR's are cheap.

I would prefer a set of CCW's though. Eventually I will pick up some CCW's.
