I figured it might be best if I finish the modifications on the bike well before next summer, so it was time to build the water injection. I drew up a spray nozzle holder in Inventor and printed it in nylon last night.
After removing all of the support material this was what it looked like, very tricky to take a picture of a nylon part since it is both white and shiny...
The other side where the nozzle will be fitted.
While I had the nylon filament loaded I printed a miniature crossbow for the kids, it shoots matches over the entire kitchen!
The best thing about 3D printed nylon apart from the strength is that it is 100% solid and can be milled, turned and threaded like a charm! Here I am threading the nozzle holder with 1/4"NPT.
With the nozzle in place I hooked it up to the pump and test flowed it with water, no leaks at all so I am satisfied. The plan is to fit it through the front wall in the air box so the spray cone is aimed directly at the compressor inlet.
I also made a bracket for the water pressure regulator, the placement of the regulator and pump needs to be out of the way for myself while riding the bike but eventually I figured out a good spot.
Just finished welding the bracket to the water tank, it isn´t the best looking part on the bike but what the heck...
Here you can see the entire system fitted to the bike, I haven´t decided yet if it will be controlled by a boost pressure switch or a simple push button switch on the handlebars. I´ll figure it out later.
Cheers!
