Velocity Stack

Somehow I managed to snap one of the lugs off a velocity stack when putting a nut on with my fingers. Either I'm a damn sight stronger than I think or it had fatigued through. Anyway I'm after a replacement and was wondering if anyone had one?

Look at the fracture, if it is completely shiny and clean it was you. If part of it looks polished or dull it points to you finding an existing defect

Dull and granulated. Looks like it's been failing for a while.

I think Lotus calls them inlet trumpets, also known as bellmouths. I believe velocity stack is the modern name, or maybe it's an americanism?

OK, that sounds likely. I think we've had quite enough of 'americanisms' though. Witness the recent mess we're in

. Personally, I'll stick to trumpets
