When was the last time you raced? All these old guys prove that if your hearts into it, then yes it's fun, but I don't recall you ever really posting race results or new best ETs, so I'm not really sure why you do this stuff. I know you like the dyno sessions and making the power and I have intrest in the stuff you post.
It's really up to you, your the only one that can really answer your question. If your passion is dyno time then sell the car and put a dyno in the garage lol we will still read your posts lol
