Hey everyone, I must say although our believes belong to different ends of the spectrum, I really appreciate all your contributions to this debate.
I totally agree that its up to everyone what they want to run in their engines but more importantly is that we share our experiences in this forum so that everyone else can make a better informed decision.
Let me take it one step further, to dissect the engine. Lets take a look at what components are heat sensitive:
1) Metal (magnesium,steel, aluminum)
2) Silicon and rubber Gaskets
3) Rubber or polymer seals
4) Rubber and silicon hoses
not sure if i missed out any other material?... pls feel free to throw in if i missed out.
All the above, if you throw it into a pressure cooker and cook it in water for a day, non of its properties is going to change. (Except maybe some form of corrosion...which is the other reason not to use water in your engine.) Therefore, non of the above is going to be dissolved or crack in 120 degree heat.
Now, if we assembled all that together and add in moving parts with tight tolerances we will need to lubricate it with oil to reduce friction.
Therefore, can I say that even if I ran my engine hotter as long as I monitor my engine oil and change quality oils regularly my engine will last a long time? and as long as expansion and contraction is consistent nothing is going to warp or crack or jam?
Now the other way around. imagine your engine's cooling system to be the pressure cooker.
We are technically boiling water or water based coolants within our cooling system are we not? All this pressure is constantly acting out wards trying to escape, isn't that the reason why we use high pressure rad caps and silicon hoses just to raise the boiling by a few degrees? With a highly pressurized system during a boil over any "weak spot" for example cylinder block that has not been torqued properly is potentially going to blow and spot a leak. Hoses and radiators get inflated with pressure and contract with cooling, constantly flexing and weakening the integrity of rubber and welds over time. Sooner or later it has to give. Yes, I am exaggerating alittle to give you guys the idea:)
So if I wanted a reliable bike to ride on because I do spend more that riding than doing repairs. I would want to take that pressure out of the equation and keep as much coolant in when the going gets tough. It is this rational that I am convinced that Evans work harder than water. Since the invention of combustion engines, water was the only available source for cooling thats why have deep trust for it. I think its time to explore alternatives now that waterless technology is available, for all you know someone might be able to squeeze out a few more hp from this:)
Sorry for going on non stop but I hope the above make sense. pheew..
