I think we covered what it needs to be. Ill be fronting my $$ for the development of this part and working with Brian at SB to make it happen. I do not have plans to re sell these but hopefully he will put his name on them and add them to the product lineup. I'm not doing this just for me, so lets have some input towards the design.
A fiberglass unit would be a much cheaper way to make small quantities. I made a mandrel that is 92+mm for a 155 pump. It is an inch longer with shallower taper. The mount is a simple folded flat that goes around the entire part and can be bonded on wherever it needs to be. The gimbal ring is either custom or 900ZXI. This could add a lot of thrust over the OEM nozzle that many are using. Im sure the guys with $20k skis will rather have $600 billet nozzles.
