As you appear to be more convinced by marketing rhetoric than by pragmatic reality, any attempt to correct your misconceptions would clearly be a waste of my time.
What you appear to be saying is that; advanced timing during starting has the same effect as operating an overheating engine, with advanced timing, under full power, at high RPM, for more than an hour. That is simply not the case.351tom said:If you ever seen rod bearings with copper showing only on the top bearing shell, one of the causes of this is what I am talking about.
indicate you have in mind either stock production engines made since electronic ignitions have been used, or engines that have been upgraded in this regard. This leaves out precisely the engines I am referring to. Take the chevy 350 for example, by far the most widely used small block engine of all time across many forms of racing , vintage vehicles, custom builds, etc. When these engines are built for performance, the stock electronic ignitions (if there were any as in pre early 1970's versions) no longer apply because the characteristics of the engine change so greatly. For example the HEI module may have had only 6 degrees retard at start. That was perfect for the engine it was designed for, but is just about useless for the racing engine with a 42 degree locked out distributor. Many times aftermarket ignition products that facilitate ignition retard at cranking are utilized, but for various reasons, many times they are not. There are a lot of variables involved, but depending on the specifics of the engine in question, you may not need to go anywhere near as far as 42 degrees to completely stall a starter motor. What I was trying to do is quantify the forces involved when this happens.During starting, the ignition timing should prevent an advanced spark occurring, so we can ignore pre-ignition.
I agree with you 100%A â€œcomparative novice speedfreekâ€ or a computer chip â€œover-clockerâ€ is NOT an engineer.
They are individuals abusing the technology.
They have no concept of reliability engineering.
They are pushing beyond the SOE to destruction.
Economics and reliability are critical to engineering.
