300#=30whp. Not even close. As proven before, a stock mustang on chicken-legs handles nearly as well as a 370Z, and the BOSS tears it to pieces.

And while I know on street ithe moose-tang is ok on MPg I suspect it is very thirsty on the track.

That's because it makes another 100whp and 120+rwtq.

And dudes my Chevy Crew cab work truck with v8 4.8 liter gets 17 mpg with mixed city and highway, it gets nearly 20 when doing hwy Lol! Leave it to Chevy to beat Mustang gas mileage with a huge truck. My Nismo is over 20 mpg combined and over 26 Hwy MPG..... but as I had said on track I suspect your V8 mustangs are terrible. They aren't the most efficient race cars.
Trade that Z in for an S2000 so you can talk about hp/L.
