I agree with the posts above. You don't even want to know what it costs! I can tell you that in the early 1990s I calculated expenses based on 60 runs with our Top Alcohol Dragster. We were reasonably competitive at the NHRA National level. I included travel, entry fees, parts depreciation, etc. If the car did not break any parts, it was $1065 per run. I can't imagine what it costs to run one of those today.
