I wasnt saying they didn't exist. I was legitimately saying I would like to see a comparison to understand the effects of the emissions equipment and how it compares to an identical vehicle without the equipment, accounting for the decrease in MPG's, added weight, etc etc. There is a lot of anger being thrown around this thread at the EPA without much supporting evidence other than "my 1977 diesel whatever gets better mpgs than this modern crap." That doesn't tell me much.
To those that hate the EPA, yes, I understand the frustration of the emissions equipment. I don't want EGR either. As I said in a previous post, two of my cousins have had very annoying and expensive repairs done on their modern diesel trucks due to emissions equipment failures.
I doubt there is a real study that gets the engine x, strips out all EPA mandated accessories, reprograms the ECU to work efficiently without those, then makes a comparison. Usually after a new imposed pollution regulation, there is a lot of re-engineering involved, which can lead to a totally new redesigned engine. Plus, I really believe there is not a heck of a lot difference, and those studies may in fact prove a too big cost to benefits ratios, this could defeat the purpose of such a regulation. I am personally all for being non-polluting, but in reaching the non polluting state, there should be a lot more common sense involved and way better choices. Who wants an EGR that breaks every 20-40K miles and clogs the engine with soot, leading to expensive repairs? A better choice would be regulating a more available biodiesel, more efficient and reliable cats and maybe find a better formula to the biodiesel. Europeans were sold in early 2000 to buy new generation diesels because they reduce the carbon footprint (which leads to the Oh My God global warming, we're all gonna fry and die drama - which is a pure scam btw, millions of years ago, when there was no human pollution as we know and when the dinosaurs were ruling the earth, the carbon footprint was way bigger than today and the earth was way greener, so as the carbon footprint can create indeed climate changes, there is nothing wrong with that, just pure scare tactics to make people buy solar panels or buy carbon credits), recently it was found out that, as the carbon footprint is reduced indeed for newer diesels, almost everything else is way worse than gasoline pollution. This is how all the "studies" are made, to serve a specific interest group, and this is the reason I usually do not trust any EPA research, or any government "science", the data is manipulated to serve those at power while, purposely or not, ignoring other details.
