Hey Riku, I'm a salesman at Team Ford in Las Vegas. My owner Steve Oliges was one of the men who helped design the Raptor and put it through its paces during testing. He races the Baja and has for years now. The picture shown in my profile is me in a 6.2 Raptor at Las Vegas Motor Speedway on 6-19-10. I've driven the 5.4 with the suspension adjusted in every way, tire pressure at different P.S.I, and in every mode and configuration possible. The jump pictured was taken max height at 50 mph. The max I could do in the 5.4L was 42mph with the corner factored in before the jump. I had both trucks with 28 P.S.I with Advance Trac Off (Press & Hold), Off Road Mode Enabled, and the ELD engaged. At the end of the day I had taken 12 customers out (I was mainly driving the truck for my own benefit), and close to 30 laps out the truck.
The conclusion at the end of the day was the 6.2 has less lag in throttle response than the 5.4 especially mid corner. More so the throttle blip needed at the top of jumps to ensure landing on all 4 wheels instead of nose diving was significant over the 5.4 by far. I hate driving with the transmission in D for handling and response reasons, but the 6.2 has better response in Drive than the 5.4. I utilized 1st and 2nd gear select all day never using 3rd. Factory configured suspension proved the best with 28 P.S.I having the most traction with plenty of give mid throttle to throw the back end out as well. While 28 P.S.I sucks with gas mileage (Around 40 P.S.I is standard from the factory) on the road and isn't ideal for high speeds on pavement, it proved to be the best ride, handling, and absorb the bumps and jumps the best on both trucks, the 6.2 was just superior by far when taken to the max.
YouTube videos are all over of the Raptor Round Up and very easy to tell which one I was in. SVT and Ford were there and since owners and other dealerships taking it easy and scared something would break, I took the truck beyond what SVT had told me to and the truck drove away with a scratched skid plate. I drove it there with 28 miles on it and when I got back to the dealership, it had close to 200 on it. I would have bought it myself if one of the customers who rode with me hadn't followed me back to the dealership and traded in his 5.4L for the exact one I drove. He was tickled to death, congrats Mike. Check out "Ford Raptor Flying" and other "Raptor Round Up" videos on YouTube. Have Fun and if its clean, it's cause something broke! -Aaron Team Ford-Lincoln-Mercury Las Vegas, NV
