Hell yes I'd be jealous. It'd take a fair bit of work to install, but to have a fifth/sixth generation Eaton supercharger instead of the equivalent of a third generation, there'd be a significant decrease in drag from the supercharger, and a corresponding increase in boost.

 

Harrop Engineering informed me that the new TVS superchargers spin at up to something like 20,000rpm.

Correction to my previous comments. I've just checked the email I received from Harrop. The new SIXTH generation Eaton supercharger is a four lobe unit vs. three lobe for the previous generations. Harrop recommended a 1320cc/min item for me (I was asking about the M90 from the supercharged Commodores). They tested a pre-production unit at up to 20,000rpm. The price for a new four lobe blower? About $2,000.

 

Oh, and for reference:

 

Toyota SC12: 1200cc/rev x 12,000rpm max = 14,400L/min

Toyota SC14: 1420cc/rev x 12,000rpm max = 17,040L/min

Eaton M90 (Commodore): 1475cc/min x 12,000rpm max = 17,700L/min

Eaton R1320 (New TVS): 1320cc/min x 16,000rpm (CONSERVATIVE) = 21,120L/min

Eaton R1320 (New TVS): 1320cc/min x 20,000rpm max = 26,400L/min!!!

 

Interesting article with info about TRD testing different superchargers on TRD Aurion.

 

BTW, I *think* the R1320 is the supercharger being used on the TRD Aurion. Not certain though. And capacities on the new R-series (TVS) superchargers range from 350cc to 2300cc. NICE!!!
