I think it just depends on where you want to go with the sport, how much you want to spend, and how fast do you want to go. I loved running 8.40’s@160mph but boy I sure was busier at the track than I am now. But I’m still in the same class running for the same money. My heart is so torn on my heads up car and what direction that I should go. I don’t have the resources to run with the big dogs and running that type of car by yourself and my age and in my condition is senseless. I spent 1000’s of dollars on a Sledgehammer nitrous kit, progressive, three bottle, scale, etc and that’s just the part of it. My engine build and converter is all built with nitrous in mind. All to go one second quicker in the 1/8th mile. Hmmm
