Well....I didn't see any comments that are being discussed here, but I did look at the Wynne oil pan, and I will say this...I think it's design lends itself to reusage more than a steel pan does. Those darn factory oil pans always dimple at the bolt holes, and ya gotta sit there with a ball peen hammer and a block of wood and knock back all the dimples. Wynne's oil pan is aluminum, which wouldn't do that. Seems to me that it's a very good quality piece, and when I saw the pic of him hand welding those darn things, I'd have to say the price certainly is more than fair.
I did see some old magnesium Otto pans for sale on Ebay...they looked sweeeeet!!! Just not a very deep sump, and it seems they wouldn't lend themselves to flying too well. Keep up the good work Mr. Wynne.........Your dedication shows.
