  1. The rod is naturally MUCH stronger in compression - its the weakest in tension when its trying to throw the piston off the rod at the end of the exhaust / beginning intake stroke at maximum RPM. This is why the diesel rod is so badly - it never has to rev very high, yet it experiences a much higher compression ratio and combustion pressures than the petrol - this is why diesel engines are cast iron. Quote "The 5.2-liter V10 that debuted in the 2009 Audi R8 has the highest mean piston speed for any production car (26.9 m/s) " " high speed diesel ~14–17 m/s for automobile engines"

  2.  @michele-janemotte7337  - If you are going to be wrong - try not to be abusive with it.

  3. those old BMW engines were astonishing

  4.  @Fincher123  I believe bent conrods are usually when the engine hydraulics.

  5. EVERYONE IN THE COMMENTS SAYING IT NEEDS TO BE IN COMPRESSION here are the facts: The rod is naturally MUCH stronger in compression - its the weakest in tension when its trying to throw the piston off the rod at the end of the exhaust / beginning intake stroke at maximum RPM. This is why the diesel rod does so badly - it never has to rev very high, yet it experiences a much higher compression ratio and combustion pressures than the petrol - this is why diesel engines are cast iron. Quote "The 5.2-liter V10 that debuted in the 2009 Audi R8 has the highest mean piston speed for any production car (26.9 m/s) " " high speed diesel ~14–17 m/s for automobile engines" CON RODS main failure is in TENSION, a compression failure usually occurs when hydraulic-ed or when the timing is advanced too much .

  7. The thing is - there was astonishingly little difference between them all

  10. THIS IS NOT ENTIRELY FAIR you have 100 years of work hardening on the old US hammer - we dont know what the Chinese hammer would be like in 100 years

  13.  @69GROMINET  I think that is either the Gordon Murry T50 of the Aston Martin Valkyrie. For comparison "Formula 1 engines are actually around 26 m/s mean piston speed and 41 m/s maximum piston velocity at redline" So its probably about right - I think the bottom line is 26/27 m/s average is about the limits of the materials we have at the moment

  14.  @MrTL3wis  Correct. But where i lived in North Yorkshire hydraulic engines were quite common - lots of fords through rivers and flooding

  15. THATS WHAT BIG BRICK wants you to think - they are just selling you as sh!t brick full of holes.

  16.  @WanderingMania  My sister lives in a house built in 1735 ish. There are advantages to NOT having buildings last forever. The irony of the British building stock is its the worst in Europe cos its the best built in Europe - its almost all industrial revolution era designed for a time when you had a coal fire in every room. This does NOT translate well for central heating.

  17. To be honest - the most impressive was the plastic one. If you want to save cost and weight and not have something that is utter **** the plastic one was the best And it failed in a predictable way

  18. Take a second to realise that the press never touched the metal - just opposing subatomic forces
