As far as RPM limits go, I've already stated it but I'm against it. As for the charger discussion, trust me when I say there's nobody that would like to see the WS class have an aftermarket limit on it more than me. I don't think, I know that 2.5" would be too big after having the class here for a few years and seeing the outcome of it. I would be fine limiting it down to 2.4" if it were ever to be done, but I also feel that I'd only be doing it for selfish reasons. It would not truly help the sport at this point with the way the classes are divided up.
I personally would never try to compete with a stock charger because I know how hot everything gets now with the amount of extra air flow that I have, let alone choking it down even more. My take on it is that there are so many trucks that have a streetable charger or could go to a streetable charger in the 2.4" range that could flow comparable to what some of the GM/Ford chargers can run. Granted their are trucks doing great with some of the Dodge 341's and 351's, but even they are lacking on the exhaust side in my opinion. I would gladly go down to a 2.4" aftermarket charger to run WS, but that would be that much more BS to deal with in what should be, but isn't, the simplest class of all.
The only answer for now, at least until the restrictor is proven/disproven for our application, is to stick with a stock OEM unmodified charger, have techs that know the difference between these and modified/aftermarket chargers, and having the rules enforced completely. Some organizations do better with this than others but not all have perfected it. Why throw a wrench into something that is already scatter brained at best?
