Diesel vs gas......................
OK folks, there have been a few to many diesel vs gas threads that have shall we say gone to "Hell and a hand basket"! So if all of you would put in you BEST, no flaming reasons for going gas vs diese...

hindle_az - Nice explaination of how a gasser works vs how a diesel works. There is work being done now on building a gasser that has direct injection just like a diesel. Apparently there have been some promising results, but there are no production engines yet. Since the fuel will be directly injected, they will be able to raise compression ratios much higher than they are now and get much better efficiency out of them. It will certainly be interesting to watch.
Jim - The reason that reliability dropped is because the typical gasser does not provide any piston cooling - it's not required. However, when you charge the intake, piston temps climb dramatically and if you don't do something about it, you will end up with burned pistons. Any engine that has a charged intake (gas or diesel) will experience increased piston temperatures. Usually, jets of oil are sprayed on the bottom of the pistons to cool them. My DMax has them but the 6l gasser I had did not. Also, you can't run stock head gaskets in an engine that is producing substantially more power than stock regardless of how that extra power is being generated. There are all kinds of after market head gaskets available that will withstand the increased power without failing.
