I got a big dog hull to put it in!:wave: Send that bad boy to florida and will run it through paces in the swamp:cheer:

I guarantee it's not scared of some mucky water.

Awesome!!!

Whose name should I write in on the bill?

Still ready?

Yeah, I nutted all over the place when I saw these the first time. I'd love to have a set of those bad boys....gonna have to see what I can do.

As for annodizing....I agree that it should be done but not on the inside. Personally, I like to glass bead the inside of my motors prior to assembly.

Can it be annodized as an assembled part? I'd think it could be. If so, I think you could quite easily make a plate to bolt onto the intake and base gasket area, then plug the crank bore and the threaded holes. Bolts will have a hard time holding on an annodized surface and you don't want them to back out that's for sure. An option on that would be to tap after annodizing.

O-rings? I recommend them wherever you can put them. I've got o-rings on my Sea Jets and I love them. I'd o-ring them myself if I purchased one and it wasn't already machined with the o-ring lands.

Why don't you offer up your ski BK?

I have an X2 you can put that engine in if you promise to return the billet engine and my hull when you are done...

He pays the shipping both ways, sure..............

Nice cases, i have a 10mm crankworks crank with a ADA cyclinder 89mm piston which we are building over here, would this match up?? the motor goes together this week, i would love to run it for a few weeks then strip it and try these cases, to compare
The ski is a 100% carbon 08 with 12 vein skat track pump , msd ect ect . pm me the price, and it is being built by a decent engine builder over here, not me, we also will have a dyno to test it on.

Thanks Sharky,

It has been awhile since I have seen ADA's cylinder. Once in while they come through the shop to get assembled/bored/ported. I don't know if the transfers will match up or not. I am guessing the ADA transfer area will be alot smaller. When I run the next set of cases I will have to decide on setting them up for a cylinders other than a DASA/Lamey cast or billet.

To be 100% honest though, I doubt the cases will make much more power in the shorter strokers. If that is the only reason why you are buying them.

Up to a 10MM and maybe even a 10MM, I can't imagine any benefit than just having a full billet motor. Sure they are stronger, but I don't think it is really needed for the smaller strokes. I could be wrong, but I think the standard cast case would be sufficent. The billet case won't really flex.

12MM and up, there would be advantages because of cutting clearance for the rods in a factory case pretty much destroys the case.

thanks for the input, i just wanted to try them as we could port way more out of the cases in the intake and also more crank case volume, but yes it will be a must, i will most likely use it as a surf motor as the surf sucks in summer then just run the ada barrell in a stock 62t set up and invest in your cases, i will start saving and will be in line for one when they roll off the production line, clear annodized or black is good and o ring for the front cover and i would buy 2 covers one for each of my boats
cheers

I will be setting up for the cases as well as the covers right after christmas

Ok,

So, one nice thing about the internet is you can get a direct response from custumers regarding products.

I am getting ready to build the production cases and I was wondering what would be the best way to fit the case to cylinders other than the DASA/Lamey.

I have several custumers asking about doing cases for their 10-12MM cranks. Some of them are running cylinders other than the Lamey.

One idea is I do a few with a duplication of the stock case transfers and let the custumer grind his own shape into it.

Problem I see is that not everyone has the tools do that task.

Should I assume that engine builders will be doing the engine assembly and will take care of porting and shaping.

So what do you guys think?

I'd duplicate stock if I was you and let the engine builder do the matching. If you are willing to invest the $$$ into such a big engine then either you know your stuff and have the tools or you are paying someone to do it. I'd say that since Joe Average isn't your target customer then you don't need to worry about the limits of Joe Average's tool box.

I second that too! I hace a local cnc guy match my stock cases to the lamey's huge transfer area so I'm sure it would be the same amount of work for the billet ones:biggthumpup:.

I will always have cases ready off the shelf to fit a Lamey/DASA cylinder.

I was just thinking out loud about what to do to match ADA's cylinder and others.

There isn't alot of ADA cylinders out there so I would just stick to stock and your own cylinders.

.....so I would just stick to stock and your own cylinders.

I am thinking so.

Well the material is due in anyday now. I will snap some shots of what the pile of material looks like when it shows up.

If anyone is interested in a billet case for a stock stroke motor on up to a 16MM, post up or PM me and I will put you on the list. This run will be 10-15 only. The next run will be larger.

I will be making 10-12-16MM cases.

Do you water jet the major shape then machine?

Faster to just go at it.

Thick material is not easy to waterjet, the spray will wander.

 

[Mark44]

Faster to just go at it.

Ok just curious I would think you could cut out most of the material with water faster than you could machine especially on the upper portion of the case.

Now that I have the programs ready, I will try produce and post of video of the machine going at it.
