Even in a forum as nice as this one, some "poking" is unavoidable. What you're saying makes sense now, if one reads what you wrote in your posts.
Getting an exact 0-60 is a little tough, for stock I'd go with factory specs. If you're looking at tracking perf by mod, you can certainly do that, but 1/4 mile MPH is much more reliable for that, even than ET which fluctuates more. I know some disagree, but I think the GenIII viper is one of the easiest I've ever taken to the drag strip, but my frame of reference is sliding a 600rwhp mustang down the stip on 295 street tires. With my car completely stock and a week old (03 SRT) I did a best ET of 11.97, but my car was strong, for ex with only corsa cat back & a mail order DC tune it ran 11.90's all day at 125.X MPH. That's a strong GenIII. Getting 1.80 60ft times to me is easy with these cars, with regular air pressure etc., you've got a sticky 345 tire, 3.07 rear, all you need is some touch on the throttle & clutch and the run seems slow it's so uneventful. My worst run wasn't blown on launch but on pushing too ******* 3rd & spun up the wheels at the top of the track on a 2-3 shift, cost 2 tenths.
But honestly, so many combos have been tested, all you need to do is figure how fast you want to be, check the list of mods needed & bolt them on, easy peasy. As for hiflo cats on a GenIII, to me not worth it for perf, more of a sound mod, as the guys that make them told they're only good for a couple rwhp, so I never did it. But I might on my GenIV as there's more of a diff based on results I'm hearing about.
Have fun, and don't worry about some of the poking, everyone here is a good sport, it's in fun and that's what the cars are about. Congrats on your viper ownership, let the mods begin.
