Just to clarify my point a bit, I wasn't saying Pro Mod should replace one of the Pro Stock classes, or that they should necessarily become a fifth pro class. I'm merely stating that it doesn't seem like the sanctioning body is doing much to try and bring in a sponsor even though they would like the cars to race at more events in the future. Also, I'm not saying dilute the existing sponsor dollars. If Mellow Yellow or Lucas Oil want nothing to do with Pro Mod or they are not interested in sending more marketing dollars drag racing's way, then sign a contract with Google, Apple, Goodyear, Exxon, somebody to sponsor the class (I know it's easier said than done). Which brings me to my next point.
Mark, I disagree that Pro Mod can't/won't increase TV and event attendance. There are plenty of racing organizations running either full blown Pro Mod or Pro Mod style classes both 1/8 and 1/4 mile that have great attendance both from a racer and spectator perspective. Plus, didn't NHRA sign some sort of partnership with Big Chief from Street Outlaws to get racing off the streets and onto the track? I don't watch Street Outlaws, but I hear it gets pretty good ratings and I've also heard/read that a bunch of the cars on the show are basically Pro Mod cars.
Maybe I'm just being optimistic, but if there was a 16 race, NHRA Exxon Pro Mod series, I think there would be some additional racer and fan interest. If they can't become a full on "Pro" class, then show the quarterfinals and semi finals during the downtime on the broadcasts between the semis and finals of the nitro cars. Then lead off with the Pro Mod final before the official Pro finals.
In conclusion, it seems to me that heads up, power adder, door slammer racing is really popular across the country so why wouldn't the largest drag racing organization want to fully be a part of it?
