Matt_E's Superfreak Build

[Boris]

Thought so.
Get a Stunt and send me the Freak.
I'll fire up the Sawzall and fill the dumpster.

P.S. I'll be nice and split the shipping with ya.

[Matt_E]

Deal.

[Boris]

Crap, another project I don't want or need.
Me and my big mouth.

[Matt_E]

Haha, you just screwed yourself, pal.

[Boris]

Tell me about it.
Not only am I out half the shipping but they ain't exactly giving away them long sawzall blades for free.

There goes this months bonus.

Just my lil' old big bore engine that I've had for a couple of years now.
It got freshened up over the winter, though.
Details:

Jetworks 62T/61X Big Bore 84.5mm, 763cc
200 psi compression
Jetworks reeds
Dual 46 BlackJacks on a Riva manifold
ATP Flame Total Loss
B-Mod pipe
140mm Magnum Pump with 13/18 impeller and Wammer/Thrust trim

It did alright in my last ski. See avatar.
It'll be interesting to see what it does with 80lbs less ski to drag around.

AM flame arrestors w/ Outerwears like Art likes ? Wondering about dual 61x airboxes on BJ'S and expensive adapters ?

[Waternut]

You will definitely need a taller prop. You are wasting time using the same prop.

If you take that advice Matt, I have a 14/19 prop on my mag that I'm looking to repitch to 13/18. Maybe a trade would be better. I haven't measured my outer diameter clearance yet though.

[Matt_E]

F/A's: I was talking to Art about this yesterday. He said you don't necessarily have to have the expensive adapters. You can invert the oem base and somehow make it work. Myself, I like running proks.

Impellers: that may be an option. I'll know more once I get a little closer to water testing it

What motor are you planing on running? Jetworks motor?

I have the same motor in my surf hull, 89lbs, warmer trim, mag pump set back and it hard as he'll with the 14/19. Also ran it with a 13/18 and a 12/17. 84mm nozzle
Even the scream ss865 is running a 14/19 mag

Some pictures from last night. I didn't do much. I tried fitting the pump. With only bolting up the front two, the shaft seems perfectly centered in the bulkhead hole.
The rear two mounts don't line up 100% with the pump, which is to be expected with a custom build I suppose. No big deal, I'll enlarge the holes in the mounting tabs.










Notice how wide the intake is and how the hull is a bit concave right before the intake.





Fitting the intake grate (Perfect fit!), plus a couple of stock length Superjet plates on there. Yah, it's short!









The battery tray. I was confused when I looked at it and had to call Tem/Nancy to figure it out. You just run a single strap looped underneath the plate.
Metal battery box for sale I suppose.





The carbon exhaust tube:





My Cold Fusion ebox mount.

Matt...get one of the large bpipe coupler-metal gasket holders for ur battery...Deka EXT-9. It's easy to secure/unsecure and the battery is super secure. I tried a one-piece velcro that strapped to itself, but it disentigrated on me after lots of fuel, oil, water spilled on it.

This thread is blowing up......I miss the X for like a day and there are 5 pages here.

[Matt_E]

With zero progress, to boot.

I spent a few hours today installing a stock waterbox, stock tank, the motor, and some other stuff. I also weighed just about everything.

140 Mag pump complete with impeller, shaft, Wammer trim + cable + lever - 22.6 lbs
Stock waterbox with two very short elbows on it - 5.4 lbs
Motor + ebox + head pipe + mid shaft assembly - 87.4 lbs
Stock tank - 5.8 lbs
4 Motor mounts plus 2 Kenney Keepers - 1.4 lbs
Intake grate (W201) - 1.25 lbs
Long exhaust hose - 2.8 lbs
Handle bars, grips, throttle, s/s switch - 2.4 lbs
Jetworks battery - 13.2 lbs
B-Pipe chamber - 3.9 lbs

Totals up to 150.06 lbs
I think I may be able to get under 250lbs for the complete ski.

Pretty much everything bolted right up. I had to elongate mounting holes in one motor mount (and Kenney Keeper)
Pictures:




The stock tank is a bit of a tight fit in this hull.




This hull is a pain in the ass on a stand, it's got too much rocker!







Cold Fusion ebox mount - seems to fit like a glove above the front foothold, but I have not actually mounted it yet.










B-pipe chamber install is easier than in a Superjet. More room.














Head pipe and tank stick out a bit above the hull, but the hood fits fine.




Trying to see if the Watcon hood seal will work.

Please wash that gas tank, its too ugly to be put in such a nice hull!

[Freakrider]

carbs are mounted backwards compared to how XScream runs them ? Art ever say why ?

I'll wash it with some simple green, but it always ends up looking like that after a season.

[Boris]

Damn it, you have been a busy boy.
Guess no one can call you a slacker after todays effort.
Nice.

It's Chucky who mounts the carbs backwards, not Art.
