Anyway, just wondering if anyone has tried running a 190 and if there are any good or bad things about it, or if it is even a good idea.
It is soley because of emissions, nothing else...it is controlled in Calif by themselves, along with the enviormental Protection Agency through out the states, and Texas Railroads in Texas for LPG fueled vehicles. No disrepect to anyone here, but engineers learn performance tips from mopar fanatics like Don Garlits, Ed Hamburger Keith Black, Russ Flagle from Indy, Ray Barton, Bill Mitchell and the list goes on forever. They do not know how to build a high performance vehicle without assembling the likes of Ford Racing teams, Mopar Performance, Direct Connection (use to be Ed Hamburger) and GM performance teams. Everyone of the specialist on these teams had something to do with racing, that's where they started and that's why they were hired. To get the most performance at the same time be able to burn off the extra fuel from high performance or gass guzzling vehicles. They have to sacrafice HP to burn off unspent fuel and emissions with these 200 plus degree thermostats. There are people who will argue this on here because they do not know anything about what makes an engine tick. They may know thermal physics or solutions but they do not know the inside of a combustion chamber from a hole in the ground.
