Out cruising today and found playing with a 5.0 S550 Mustang. Eventually we had plenty of room ahead of us, and did two 45-100 pulls Almost immediately, I had 2-3 car lengths with him trailing further. I’m pretty sure aerodynamics started to take over, or maybe just how his car is geared, but as we neared 100 I could see him catching up as I let off the throttle. We pulled over and to my surprise his auto mustang had a Roush supercharger with 700 crank hp, he said 600 to the wheels. To his surprise, I was naturally aspirated. Not sure what my 347 puts down, but apparently enough to beat him. I was excited to have some comparison and something to tell.
