See for yourselves. G's on the skid pad, braking, weight, etc.

Tech. You're right, what was I thinking. The Genesis is a real slug.
But even if you strip 500lbs. off your XF, that only puts your NA's "stock" starting point at about 14.6sec.
If you really think you can overcome the better torque manipulation a lower gear ratio offers, simply by weight reduction, then let us know when you get done replacing every body part that unbolts from your car with something replicated in Carbon Fiber.
All I'm saying is, if we could simply replace our existing 3.27's with a 3.91 posi, that's probably all it would take to get us into the 13's. Without a doubt, 3.91's and a NeedsWings CAI for sure.
Again, I wish you luck turning your XF into something that you really want.
By the way, I'd LOVE to have 300hp in my Civic.......talk about torque steer........YEE-HAAA.lol
