Spent a few hours at the PRI Show today in Indy...it was overwhelming! Probably NEED 2-3 days to see it all. We looked at everything from dynos to transporters as well as almost all the mods you could imagine. Had an interesting talk with James Jureski of Texas Nitnous Technology(Tyler,TX) who has kits for Vettes...he has NOT done a Viper, and would LIKE to...sounds like about 100 hp for about $700.00(+/-)using a CONSERVATIVE approach. I don't know much about these systems, but am reminded had much hp one can find for only a few $$. Main reason for post is to recommend attending show...know of at least 3 well known Viper racers who attended. FUN< FUN< FUN!
