It's not all that complicated. Do you know what it does?

Basically you are just trying to eliminate some of the turbulence at the outlet of the impeller at the inlet of the bowl vanes.

By installing/building a plate between the two parts,  you are potentially reducing the aerated water going into the bowl. You may see an increase in performance with precision instruments,  but doubt seriously the Ass-O-Nometer will be able to differentiate.

Sometimes we see them recover from a rough water ventilation quicker,  that's about all I've ever personally witnessed.

I have a pattern for one of its something your interested in.

Pretty simple once you think about it. I always set mine up to be .030" away from the trailing edge of the impeller.

Don't over think it.

It is my humble opinion that the cone shaped stuffers are completely over thought.

JMO.

Flat surface to flat surface between the bowl and the impeller is more than adequate.

Snake oil is only good for turning a profit.

Cool thanks for info ...I'm just making sure flat stuffer will benefit because coned  is more time consuming ..

Will a bowl stuffer raise jet pressure?

Basically.... it won't hurt

Gt are you referring to a higher end hp deal?

Well I guess I'll report what change it makes on my deal. Unfortunately I'm making lots of changes at one time.

IDK, my stiffer sure seems to make a difference.

It's when you stuff the stiffer that the true performance is noticed most. ..



Hahahaha

I kill me sometimes.

Still needs finishing bolt holes and shaft hole .... What clearance are we looking for between impeller and stuffer? .030
-.035 ?

I dunno..... 30-35 seems to be the running theme.
 
But idk what these should be at

The number could be pretty small.

.030" would be really safe and probably as wide as I would go.

Think of it this way,  the impeller drives forward and there is little chance of contact under power. Deceleration could tell a different story however. I've seen as much as .005" end thrust on a new double row ball bearing.  That being said, it depends on what you feel you could get away with.

You could just build it to .025" and cut some labrynth grooves in the face.

In all honesty,  it's not going to be that critical ultimately.

If you live in an area where frost is of concern, don't forget to drill a small drain hole at the bottom.

What's a labrynth groove?

An extreme version of a tapered labrynth.
