Big Tire Outlaw questions

[Dave Rifkin]

I went to Atco yesterday; they had Pro-Mods, old time funny cars and a group they called "Big Tire Outlaws". These were great fun to watch but, for some reason, they only ran 1/8 mile passes. I asked someone in the stands why that was and he said because they'd run too fast in the 1/4 and would have a hard time getting them stopped. What I found strange is the Pro Mods ran 1/4 (or 1,000' I'm not sure) and they are faster than the Outlaw cars. Anyone familiar with these cars who can explain it to me?

Also, I noticed a bunch of fast cars running nitrous; I have seen plenty of cars running nitrous but, these guys purged the hell out of the lines before each pass. You would almost think they'd have to refill the tanks after each run; what's the reason for such a long purge?
