Now this passing lane starts in a long curving section of the highway and continues to twist and turn for a another mile or so. No racing at this point, just slightly faster than 55 all through them.
We finally get around the last curve and its a long upgrade straight up for almost a mile. This guy knows I am tailing it and as soon as I start accelerating, he steps on it. He gets a head start of about 10 car lengths. He has 1 passenger. I am weighing in at about 3350 lbs at least with the wagon loaded with all its seats, people and mushrooms. The civic is probably about 3000. We came out of the corner at about 60 mph.
Well, I caught him at about 92 mph. We were side by side and I could here his engine tone change and it seemed he started to gain on me. But at the same time my wife said "OK, thats enough!" so I had to back down.
So while I don't know about the top end part of the "challenge", I definately caught him fair and square till my wife called quits!

I did the whole pull at about 8 psi, not a knock to be heard.
