i was only aware of the Ford GT using a lsyholm twin screw didn't know AMG did it as well.

The Efficiency of the TVS series has brought positive displacement superchargers back to the oems (jags (use gen 5 roots i think), ZR1,Zl1,Cts-V,GT500, Holden Commodore, the new lotus's even use an R900 TVS)

For reference lysholms are about 65% thermally efficient at peak, compared to 70+ for TVS. the R1900, 2300 (CTS-V, ZR1) peak at 75 and 76% just shy of vortech's claimed 78%).
