Whether you dyno or not, the math is still valid. For a given amount of weight, it’s going to take a certain amount of power to achieve a ten second ET. If the power to weight ratio won’t support that performance level........ you’re not going to reach the goal. I think a big factor on whether you get a “10” or not is going to come down to what the car weighs sitting there on the starting line. But trust me....... I’m not trying to preach to you about what you “need”. I def want you to go about it your own way.
