I love to challenge myself, and build new things.

Awhile back, I decided to build my own jet pumps, and here's my big hub 148mm 12-vane that will go in my personal ski this season. Since this and another 6-vane turned out so well, I'm thinking about building another 18-vane - just because I can, lol.
:scratchchin:
I love it when a plan comes together.

Whats up with the spacing between the vanes?

The amount of space between each vein makes no difference in performance. The only thing that increases the pumps velocity is the number of veins and the overall diameter of the pump per sq metric inch volumetric efficiency per flow rate at the differential pressure chamber.

Is that cast and only slightly heavier than stock!!!??? Sick! Count me in. I will back to back test.

Your pump shoe has held up great!

Where you sniff'n that MS109 again?

i dont think its casted looks like every other vein was welded on and then smoothed out, def a sick pump if you could get this down to a science and be cost effective youd make a killing

LOL. I love the speculation! It's stainless. As for the spacing, if you look closer you may notice that the vanes are "paired". It's just something I wanted to experiment with. I don't plan on selling them outside my circle of riding friends. IMO the Solas 12-vane is such a great value, and much simpler to set up.

Yea, I saw the pattern of "two's". Just wondering what the theory was behind it. It'll be interesting to hear how it works out

Looks great wish I had the skill to try something like that .... Very precise making two stator vanes perfectly crooked together . Fo real doe , what is your hypothesis with the vane spacing . Is it just something you wanted to try , or do you have some double top secret scientific hunch.

I love me some MS109!!! That stuff really helps the prolific velocity data placed by the dynamic sensitivity of the collateral combustion.

Is it me or has Gil turned into some kind of hydro dynamic physicist ............ high on MS 109 .


Teddy ,don't be so hasty with your thanks

Hypothesis? Well, since you asked.... I had thought that the spacing would make me hook up more quickly with women, but that hasn't happened. Each pair has two different length vanes. It might work just like any other Skat/Solas, but I wanted to see if it would give a different feel to the initial hit/hookup. Call me crazy (or Shirley) but I just like a good challenge. Maybe next week I'll cure cancer.

Special FX, I built them as a bolt in replacement for yam 144 pumps. It can be used with a std 144 wear ring and prop. Since I wanted a bigger pump, I made a couple 148 wear rings as well as custom driveshafts which allow the bearings to be closer together. With the number of requests, I may reconsidder building more of these to sell.

I would have to believe in theory that the new style of vein spacing will increase the longitudinal launch trajectory into the dynamic propulsion created in the center vas of the pump cavity.

Thats my thoughts for now, more to come later.......
