Well the maximum von-mises stress (which is a yield criterion) was showing 450,000 psi. Yield is where the metal deforms and is unable to return to its original state. So permanently deformed. The Ultimate Tensile strength (or the point of breakage) of titanium (your run of the mill 6Al-4V) is 130,000 psi. Ya. Something was wrong with their analysis... I can't say how much their part can take because the analysis was done wrong.

oh ****... thats why Comptech pulled the plug on the product... heheheheh
You should have done the stress test on the Supercharger bracket....
V1 bracket was a joke thats why it kept falling apart. V2 bracket just supports the weak point but it's still KRAP!

Well.. I didn't do the analysis on the part itself. Just a critique of the analysis that was done by somebody on Hondatech. The comptech one looked nice and light, but the part needed to be modeled correctly. The ASR one looked like one big hunk of metal. If there were problems with the part, it would've shown up. At the time, I couldn't have said if the comptech one or the ASR one was better strength wise...
