Title: Multi Volume Nozzle
Post by: GT Jets on December 06, 2008, 09:21:54 PM: Over on the other site, someone asked of an "on the fly adjustable nozzle", to be able to tune the nozzle for different uses, anyone ever seen one of these?, I made one back in the day and did get it to work OK, but did not get very far.

I still have the one I made, and I also know where I went wrong (could never get the reverse gate to work for beans).

Any thoughts? I would love to build this thing and get it to market, but don't know if it is something that is "needed", It didn't work the way I thought it would, in fact quite the opposite, but worked just the same...

Any input would be greatly appreciated, also if you have seen one, let me know.

Thanks.

Futs put up a flyer on one and I know HB did a write up on one, not sure if it was the same. It was even in thier calender that year. I'm almost positive it was debut on the back of a 20' Carrera Eclipse and was at the LA show. :banghead: :banghead:

Just curious, why did this not take off, too much money? The one I built was super simple and seemed like a good idea, that thing looks like a blue nightmare...

Thanks for posting!

The article said there was GREAT improvement in performance. I think that if you have anything that you say will make your equipment 2 mph faster, someone will buy it. Just my .02, from a drag boat guy, if that’s worth anything.
