I know a lot of people have ben saying this for a long time. With the current political landscape, it is more important to watch your P's and Q's though. Obama issued an executive order a few months back stating that emissions were an emminent danger to the general health of the American public and posed a great risk. With this declaration it gives him much more power and scope to do what he sees necessary to "protect" the public from themselves. That being said, the big polluters will be addressed first such as coal plants and current vehicle emissions. I can see a day in the not so distant future when hot rod vehicles and trucks emmisions are in question. Lets face it, a 16 year old blacking out 4 lanes of traffic is emmiting the eqivelant af many cars emissions.
Like I said, either we police ourselves or they will do it for us. A few things need to be addressed for this to be taken care of. First, is for the owners to properly tune their vehicles. Second, correct injector spray pattern. This is often overlooked. Third is airflow through the engine, head and cam. Lastly is turbocharger technology. This is something that is really starting to be addressed. BB and lighter turbine sections are something Garrett addressed a few years back but they didn't have the ETT wheels to flow decent air at higher boost numbers, that has been fixed. At SEMA Borg Warner released its new line of chargers that feature twin BB, Titanium based turbine sections, and increased efficiency turbine sections. I think it is up to every truck owner and Vendor to work together to clean this sport up. Like I said previously it is a very serious subject.
