The trumpets we used were jenvey spun aluminium ones, far to thin and the all broke up under high boost.

This has hapened on three different inlets to date

Probably due to vibration and thickness of material

Although there is supposed to be an even pressure all around the trumpet the air is fed in from one side which can cause problems.

I now use Jenvey cast short trumpets, think they are 19mm

They have been fine for 5k miles now
