What you are referring to is the acceleration of the water. Delta P is proportional to the acceleration. The pressure at the nozzle is the pressure at the nozzle regardless.

Besides that being a very quick Calc-stimate, I think the error is in multiplying by 3 (3 blades). I think one of each of those blades covers nearly one rotation right? So it's more like 5,400/3 in that case. That's 1800gpm. EDIT: Although.. with 3 blades each moving the 3 inches of water for...

Holy crap this is awesome. Thanks all! (mostly JC lol). I asked because i have been experimenting with a on/off valves to temporarily dry my B-Pipe for top speed runs. My pipe is currently tuned for mid-Range, and i ran 49mph GPS. I may even put more water in for lower RPM power band, which...

Nice! I like it. I will suggest to run a large radius rounding end mill on the front side. I think the biggest complaint with the most hated finger throttle on the market (blowsion) is the squareness of the front side. I had one and it began to actually pinch my nerves in my finger.

I am curious if anyone has done any tests to see how much pressure is generated at the cooling line inlet. For example, if we took a cooling line end, capped it off, and put a gauge right there, what would the gauge read? Just out of curiosity. Thanks!

I wonder if anyone has thought of making equal length header?

This is some really nice quality work! Keep it up!

oh i see the adapter! My apologies.

Those look like Dual 44's... 4 bolts for the flame arrestor, and two lines for each fuel pump.

Yea I did that. Maybe I will double it up. I also just took a spare latch i had, drilled and tapped 3 holes into the top of the hook for set screws so i can increase the pressure on the hood. However, i failed to realize that this will negate the hooking action if i go too tight (the hook will...

Hi, I am looking for advice on the same Hood Issue. Seal is compressing, and latch coming undone with hood tricks. Thanks!

Thank you JC. Nice reply! Thanks for reading my long winded comment. Your reply helps alot. I wonder if the top vs bottom screws differ in water temp because the bottom is closest to the water supply, and the top screw is water that has run through the pipe already. So, bottom = cool water which...

I too run one line into the motor, and one into the bottom of the exhaust. For the motor, the line separates via a "Y" fitting, and each cylinder gets a line in. Then, i have two exits in the head. They EACH go overboard, with equal length hose. I wanted to be sure I can see that each cyl is...

ok i was wrong. Gld to see you have a 701!

I am betting it's a 650 right now because of where the spark plug wire holder is placed. See that rubber thing on the front of the engine that looks like a dog's nose? On a superjetor waveblaster, that should be in the back. On something like a Waverunner 3 650, it would be placed right where it...

The hull looks clean! The engine bay has been tempered with. Like Mike W said, that could be a 650. Make sure it isn't. If it's a 61x/61x that runs well, i'd do 3500.

uhhh those are silly good prices for Carbs. Am i reading this wrong?

ugh.. I want.. my sense of financial security is being tested. GLWS

I like your set screw idea! Also, your shoulder bolt idea is good too! I just found some that would work on McMaster! lol maybe I will order one sometime this summer.
