Quite an interesting thread to read this one. I am not a mechanic and i found it rather amazing just hearing all that theory behind a combustion engine. I guess its something that i just dont think of regularly but it all makes sense. I think the level of aggression often gets a bit high on threads like this when different opinions surface but i suppose its not that bad. I doubt anyone takes things too personally..
It would make sense that the rod would stretch though. Im not an engineer but have done a bit of physics through uni and it all makes sense. I mean when i first started driving a car i didnt even think of chassis flex as existing. Just wasnt something i'd thought of.
The rod will stretch, i mean look at the speed that the piston is having to move and more importantly the acceleration involved. To accelerate up the piston bore and then come to an almost instant dead stop and be pulled straight back down... The forces involved when you are talking about a piston that weighs what 500grams or something? Being accelerated that quickly it doesnt surprise me there would be stretch. All materials have a point at which they'll flex or stretch or break. This would also make sense to people who have to upgrade their rods when doing an all motor 10k redline engine or something. The rods are only made to handle a certain amount of stretch due to that certain amount of acceleration. When we go adding a further 1000rpm to our cars or more it adds a massive load on the rods - of course you can combat this to some degree using lighter pistons but it all makes sense..
Its good everyone shares their knowledge, i like thinking about such things.
As for all the aggression, as ive said before - where is the love?? lol
