Stage 3 Audi S4 vs Vortech Mustang GT

My stage 3 S4 vs my friend's 99 Mustang GT with a Vortech Supercharger and other goodies (stock fueling). Both cars on 91, S4 running 19-20 PSI and Mustang running 9 PSI. No launch on the S4 (taking care of the clutch). This was with my old setup. THE MUSTANG DRIVER IS INVESTING NICE $$$ FOR THE REMATCH!! SC @ 18 PSI, fully built engine, fueling, etc... Estimate 550 RWHP... COMING SOON!!
