Does anyone know where I can find some sources of NACA ducts with 2" outlets that I can use in the engine compartment? I need something that will withstand higher temps so they won't melt or catch on fire. I'll be using 2" 600 degree orange scat hoses on them. I found numerous ones made from plastic and even carbon fiber ones that are more for inside ventilation. I found some large ones advertised as high temp that had 4" outlets, but that won't work for what I'm trying to do. I plan to rivet them in place.
Thanks,
Steve
