ok now, i have a 820 lying around and a penguin 300gph powerhead. should i try messing with these or just go out and buy a 6100 stream. can i get the same flow out of something i can make at home for less or i just wasting time. i mean real flow not just approximated flow

That 820 should push some serious flow if you use the larger propellers (1.75" and larger)
The Tunze is nice no doubt but too expensive for my pocket otherwise I would not have even attempted this mod in the first place.
And yes you WILL see some serious flow coming from these mods. If the people on this thread have anything to say about it

thanks for the info on the tunze's, you guys sure know a lot.
zapata41, i suuggest you try to mod your powerheads. you'll be impressed at the flow. especially if they are just lying around. i was going to put in a closed loop with a mak 4 but now i've decided against it. just a couple of the powerheads modded per this thread work great.

Are there any suggestions for places that I might be able to find stainless steel rods for the shafts rather than the carbon-fiber?

Mcmaster maybe
Any local Machine Shop
ThomasNet will also be a good place to look for local suppliers.

A Quiet 3000 stock at 780gph should have plenty of horsepower to spin really large propellers I think.

You could erasily do dual 1.75" Dumas on that or perhaps something even larger and more aggressively pitched. Check out Octura propellers.
That thing would be INSANE though.

How much space is left even with the 1 3/4 hole saw in it? You'll want some space between the wall of the shroud and the propeller blades.
Also Since the shroud is already there, I imagine it would be simple to just enlarge the existing inlet slots, perhaps making them run out longer and use the existing cross brace too. No sense reinventing the wheel if you don't have to

well give me a pro # and what not so i could order it up and i will try it with the quite one, since i almost just bought a pair of streams, so if i could get a QO3000 to work then i would be happy, since a stream is about as big as a football.
there was probably about 3/64 on each side of the hole saw bit

Here are some sources to order Octura propellers
http://www.funrcboats.com/category.aspx?categoryID=109 (they're kinda expensive)
http://www.prop-shop.com/WBTPROP5.HTM (you might have to call or email them to order these)
Or directly from the manufacturer (mail order through catalog only)
Octura Models Inc
(847) 674-7351
7351 Hamlin Ave
Skokie, IL 60076
Here's a propeller chart that will tell you which models, sizes, pitches, and whether they're plastic or not
http://www.pirespreto.com/octura_catalog3.htm
I would venture to say that anything 1.75" up to 2.00" would be a piece of cake for the Quite 3000 to spin. You could always order a few different sizes to try out as well.

For the 820 I would try out a 1.75" Dumas first then perhaps if you think it can handle more, try a 1.77" Octura 1445
A Quiet 3000 turning a 2.8" prop with a 3.78 pitch will put out considerable amount of flow. You would have to test this out of course but I'm guessing easily 3000gph and more (leaning more on the more)
Here is a good article regarding propeller pitch and how it affects how fast a boat can go. You can pretty much translate that to flow.

:lol: Actually the American way would be more like -
Invent product, try to manufacture product, be forced to pay Johnny 3IQ-GED Loser $35/hr to screw on the guards, close factory & re-open in country where idiot work gets idiot pay.
But I digress......
Thanks to one & all who refined the mod - props should be here today, have pump, just need pipe pieces.
I have two Tunze 6000's & a multi-controller so I do plan a head-to-head match up. If the maxi's are quiet & can function on a wavemaker w/o making noise I'd be happy to sell the Tunze (though good they are expensive & HUGE).
