Billet 800/1200 Cases Superjet

[breed6903]

I am finishing up 800 and 1200 version billet cases. The platform is based off of the GP 800 Yamaha (66E) Motor. I use the stock crankshaft and cylinders for the 800 version. Cylinders can be big bored to 87MM to make 927CC. The picture on my profile shows case assembled with crankshaft and mounted in SJ using 701 Bed plates. Bolts right in any oem superjet no custom motor mounts. I will have them on display at Georgia ride. CASES will be between $1800.00 $2500.00

I am also producing a Billet Aluminum MAG 146 12 Vein Pump as well as a custom gas tank for use in superjets and Waterdawgs REV hull. The MAG Pump will be between $800 and $1000 (Custom Prop Included in that price).

Give me your input on this how manny would be interested in purchasing any items. My e-mail is breed6903@yahoo.com.

Keep up the good work Brandon!

When I start building up my 927 platform I may be interested in the mag pump. The more people doing R&D on this platform the better!! :woot:

[DAG]

Woot
+1up for the small gas tank, as long as its not $300

[butti]

do you guys make any cool 701 stuff?:tomato: :loser:

[breed6903]

Sorry not going to beat a dead horse

[waterfreak]

Wow, that's awesome!! I'm glad theirs somebody else making this stuff available.

You got good pics ? will the mag pump be compatible with the skat (ie prop's)

[Sanford]

Anyone that has picked up a billet handpole mount knows just how heavy beefy billet parts are...so I ask, how heavy are these 800 cases?

Any better pictures?

[breed6903]

yes it will work with all stock 144 parts just port them out

I think you would find a huge demand for Billet 62T Cases . Make them ready to take up to a 10mm stroker crank. Demand would be 10X that of the 800 cases. Just my opinion.

At those prices, I doubt there would be much demand for 62t cases, as they are much more common than 66e cases, IMO.

There is only so much power 62t cases can give, i talked to jeff at WDK for a while about this yesterday...

Why??? Why would anyone spend that money on 62T cases when they could, for the same money, build a 66E motor that will bolt right up into a Superjet, and have a +10 mm stroker built right in, stock form, and have lamey style cylinders in stock form?
Unless you already have all the required parts (10mm stroker crank, lamey, etc), it would be hare-brained to go that route.
And if you did have those parts, sell them, get a 66E, and some cash to spare. :biggthumpup:

But what about the cost of going with the 66E set-up? Custom exhaust, electrical,intake ect.

Does it run that much better than a Big bore stroker?

OHHH YEA!!! According to jeff, the 62t platform with a lamey and stroked compared to jeffs 1200 is going from a 550 to a strocked lamey...Thats a huge difference!!

[kurtwolff]

One of the cool things about this new style of case is that it utilizes the 650/701/760 style bedplates, so it would be a bolt in on B1 and all Superjets; the exhaust and intake that WDK makes would be the only custom parts needed. I agree that it wouldn't cost much more than a BB Lamey platform, and the gains would be tremendous!

The exhaust and intake are custom - about the cost of a stroker crank for a 62T setup.

The electrical is not custom.

will the 6m6 and 62t stators fit on it? what flywheel cover is used?

[kurtwolff]

I would imagine that these new cases use the 66E electronics setup.

66e

lol yeah.. like only 200 hp ! but low hour rebuilds are the problem..

[Sanford]

Another possible issue, is heat-soaking. Unlike billet cylinders that are water cooled, case temps keep raising and stay there. With sand casting (OEM) this heat is quickly dissipated.

S&S Cycle had issues with the rubber seals because of the way the billet cases heat-soaked when under stress. Not sure what they did to resolve this (remachine or different seals).

hard to compare an air cooled 4 stroke to a water cooled 2 stroke.i think it would be a non issue.a 2 strokes low end is also cooled somewhat by the atomized fuel/air mix.ever notice how cold your intake manifold gets sometimes?same principal.

[Matt_E]

The intake manifold gets cold due to carburetion - vaporization of the the liquid fuel. That doesn't have all that much to do with the fuel temperature, and it doesn't occur in the cases.
Note that some Seadoo motors do indeed have water-cooled cases.

[h2odesperado]

can you explain this more? I can almost grasp it but not quite. As temp goes up pressure goes down and volume goes up and density goes down? Is that even related?

[Matt_E]

The fuel goes from liquid state to gas state (incomplete). This process is endothermic. It needs a certain amount of energy from its surroundings to commence. (Called heat of vaporization, or enthalpy for a more general term)
It pulls some heat off the surrounding metal of the intake manifold.

Evaporating rain does the same thing - it cools the surroundings somewhat.
Get cold stepping out of a shower? Same thing.

66e

no, brandon uses the 760 yamaha front cover with the stator mounted on the front cover. You'll be able to run the superjet electrical box and aftermarket cdi's already available.

thanks for setting me straight.i hope i didnt confuse anyone!

ahhhh... thanks!:biggthumpup:

i understand the concept:biggthumpup: but how could this NOT affect the cases ?vaporization happens all along the intake tract which in a 2 stroke includes the lower cases.i may be way off base here but thats the way i have always understood it.

[Matt_E]

Fuel is vaporized in the carb and in the intake manifold (to some degree). There will be no further vaporization down the line. In fact, the temperature in the cases goes up again due to crankcase compression.
That said, I wouldn't think crank case temperatures are much to worry about. But I don't know.

[breed6903]

All Stock 701 ignition will work ont it. The 760 ignition will work as well. Uses any newer yamaha sit down starter.

SWEET!!! ill probobly be buying some of these next year!

[RiverRat]

Do you have any more pics?

[Lakeman]

I like what you are doing here. What about the pipe, exhaust manifold, and intake manifold to complete the package. At the current time Jeff at WD is the only one selling these items that I know about.

Well you be selling these items also? When you ride a 66e ski, it is like stepping off a dead horse on to a wild Mustang. Night and day difference.

Sorry not going to beat a dead horse

[Lakeman]

I put a 66e in my Xjet for about $2,250.00 or there abouts. Compare this to a Lamey motor set up. You just have to hunt for a good deal on used motor. Strike a deal with Jeff @ WD for the pipe and both manifolds first. While you wait on these parts keep your eyes and ears open this summer for a motor.
It sure is a hand full.

Check out the gallery I just added some

[dirtyjersey]

looks good!, I'm excited with where the aftermarket companies are taking the sport, keep the parts comming, and affordable.....I like you setting your block up to accept Yamaha parts it simplifies the process, good work.....

[gpblaster]

What gallery are the pics in???

Later, gp

Yeah I looked and couldn't find the pics either.

Sorry to bump an old thread but I was curious to see them.

Brandon,
Great work man...long time no talk, now I know why.....I'll be calling soon!
