Dave
Excellent post, I will have a go at this, additionally I want to look at the difficulty of a sump guard option in light of Frank's incident.
After posting my first comment this morning. I would never have thought of an under tray, but thinking on from there, Would a deep fabricated 'traingle cross section' of thick 'Ally' with a couple of tie braces, set across where Dave has the back of his undertray, have prevented hitting my sump because I'd have hit that first.
I have noticed that modern cars now have many plastic under-trays to improve the slip stream of the underside of the car.
Racing cars do the same trick to make it as aerodynamic as possible.
Dave's idea is right on track and certainly a worthwhile project to tackle on a winters evening if you have nothing else to do!
but Oh that sumps sticking down is a major worry, how about a smaller sump or possibly raise the engine?
