I have a suction cup mount thing for my side window that I use for in car pics video. The off the speedo picture is a buddies I have only had my car past 160 once and it was enough I didn't use up all of 6th gear. 6th is a .67 overdrive and its a long gear the car needs downforce to reach top speed. Jaguars racing team lowered one and added a spoiler it went 225 at Bonneville Salt Flats.
Here is 70ish to 140 ish I'm racing a ML55 AMG on the way to SEMA
uphill
Here is the drag strip, I can't use full throttle in 1st gear even with the Pilot Super Sports so 12.8 @113 was all I could manage. The car has a 12.5 in it with traction. One of my Jaguar buddies is running 11.9's at 120mph with a smaller pulley and a tune on street tires. The pulley and tune are $2000.
I raced a very hot Mustang (11.16 was what it ran) and tried a full throttle start, wheel hop is an issue. The stang sounds fantastic though right!
In traffic you can leave a light in first gear and at anything under 20 mph floor it and created wheel spin into 2nd gear, its fun but I wish I could get traction. My rears are 285/30/20 PSS I have heard from other owners the car freaks out if you mess with tire size.
