EDIT: Just came across some old discussions on RX7Club where you were praising the NRS ceramic seals (back in '05, I think). Knowing your stance on ceramics seals now, what changed? I'm not calling you out and I understand the low impact strength of ceramics. I'm just generally curious why the change of heart?
Patiently waiting on the COP adapters too. They'll save me ~4 ft of wiring harness and eliminate the need for four ~2 ft ignition leads. |
What changed was I bought over 70 sets of ceramics from Sven, I learned the 'hard way' that ALL ceramic products are 100% FUCKING SHIT! just like every other person has done in reality. I found on through exposure to that many end users through all different applications that this many customers go through, what I found was RAMPANT unexplainable FAILURES, ones that happened with NO formal reason, no fault of customer, but ALWAYS this was blamed on something (convenient excuse) for Sven. To his defense I went through exactly the same thing with Ianetti as well, random failures, and ALL of these I find out through using more than any one else is to do with a fundamental lack of FRACTURE TOUGHNESS and this is an inherent flaw in ceramic materials. They ALL have this flaw in them, they ALL have internal defects like all materials do have, but in ceramic case its a flaw that the material simply cannot handle in any engine application and under the normal stresses and stains of operation (even NA) they just randomly fail!!! (as I was seeing through my extensive customer base have sold so many sets of these pieces of shit).
If you look close its not just me who says this (though I have more experience than anyone on this due to the volume I supplied to so many end users), and all go through exactly the same thing (rampant non explained failure methods) that 99 times out of 100 end up in an engine that totally goes into the parts bin!!!!! And in a turbo engined case its a given that this is what will happen.
After so many years and going through that experience first hand I said to myself FUCK THIS!@ there has to be a better way to engineer the merits of a ceramic material but also have the positives of the ductility of a ferrous material that is specified and treated right. It took me near 7 years of testing to come up with my own specification that does it, and it does it like no other. I made something that is failure proof, but is compatible with the rotor housing surface. Its made for life, and its engineering quality rewrites the book on how something should be made, not cheap, but its the best by a long margin over anything else made to date.
From every bad experience we learn something and the main point is to make a better product, if this principle was not followed then we would never have had better rotary engines, instead being stuck with the 10A shitbox LOL, so yes its a constant evolution until you actually solve a problem. I have the best apex seals ever devised, does it mean now I will rest? NO! I will keep on going like I have the last 22 years and keep on leading the way in development and pioneering the best solutions, be in COP, Water Injection, or APEX SEALS
