I can roll the throttle on and it will keep the front end down then mostly. It's just if you hit 1/2 throttle or more before the truck is up to at least 12-15 mph then it will lift the front end. In the first video I was able to hit full throttle a few times but only for a second or two. It started to run out of room on the baseball diamond before I could really open it up for any sort of time. I'm gonna guess top speed is most likely somewhere around 40-45mph. Right now it is a 13tooth pinion so I could gear it for more speed, but with those big tires it's a handful even at 40-45
