  • AWS has some pretty "aggressive" treatment of aluminum that's probably an "average" value. Design values for aerospace are much more conservative (95% confidence for 99% of population), so the knockdowns are much much higher for higher temperature exposure.

    • Interesting. Can you give an equivalent example from an aerospace standard?

      • Of strength lost versus temperature? At 200 deg F, there starts to be a transition to losing permanent properties with elevated exposure time. Intermittent exposure is ~20% lower yield strength from memory. Go up to 250 F and it's in the ~30% range for intermittent exposure. Hold that for ~10,000 hours and I want to say it's about 60-70% down below room temperature yield strength. They don't cite what it recovers to, but I assume the long exposure times are near permanent values.

        This is from MMPDS, which is Metallic Materials Properties Development and Standardization. Formerly Mil-Handbook 5.

        • Lol, dang, talk about a "squirrel" moment! I've decided to keep the raw look, but not sure if I should do a clear powder-coat or not. And yes, it came with a clamp for the throttle body.

          Has anyone done a drive by wire setup here btw? Looking into accelerator pedals to use (I've seen GM and Z pedals so far). The pedal in my Spec B Legacy looks like it may be a good fit, so I may toy with that, but curious what other people use.
