sorry to go off topic but i was reading this article and found this very interesting:
FORD will offer a 2013 Mustang Roush package offering 3 stages(1,2,and 3) but the one that caught my attention is STAGE 3 saying -"Stage 3 puts a supercharged 5.0-liter V-8 rated for 565 hp and 505 lb-ft of torque under the hood. The forced induction comes courtesy of an R2300 supercharger featuring Eaton’s TVS (Twin Vortices Series) patented technology." WILL THIS BE 1/4 COMPETITION WITH THE ZL1? and here is the link to the article guys.:
