As far as horsepower, that’s what the dyno said. Could be right, could be wrong. I’ve seen guys at my local track use atv ratchet straps to hold the front end down. It’s all trial and error. I raced for a season and a half before I got my 10. If a person was smaller and got off the line perfectly, consistent 10’s could be achievable. I’m 6’ 220 and always tried to have a full tank of 93 when I went out. Weather that helped or hindered I knew I wasn’t going to run out of gas. (Made 17 passes one night). I thought I was king shit until I had my butt handed to me by a 600, it was humbling.
