wouldnt it be great if there was an alternative

[waxhead]

Here is a drawing i have been working on
i have yet to finish and to add the pv,s

I am hoping to get copy of tsr so i need to run the port time areas yet but its close


It needs another 20 or so hours to finish


I have the use of a 3d printer and i will get it printed out and see how it works out

Will end up with a plastic cylinder useless but i can at least check design

 

[jetskiier]

Alternative to what?

Alternative to what?

okey::smashfreakB:okey:

 

[waxhead]

A big bore 800 cylinder

 

[yamanube]

That is for the 66e I am assuming?

 

[waxhead]

Yeah its a copy of a gp1200 cylinder with a few changes

I havent finished yet as you can see but its getting late so thats enough for tonight

 

[the only couch rider]

That is for the 66e I am assuming?

it would work on either the 66E or 66V cylinder... the only difference between the two is the port time.


i would assume it would work on the 66V cases with the same machine work you would need on the 66E cases

 

[waxhead]

Yeah it would

I had thought about drawing the exhaust side to allow the b-pipe to bolt on


Not sure yet i have to meausre the b-pipe manifold etc to make sure there would be clearance
thats why its good making it out of plastic first

it would mean it wouldnt run pv,s but what the heck it would still hit like crazy with a big bore on it

A 1200 freeride engine i reckon it would be a good thing in the surf

I did some more work on the drawing this morning
Got the transfers starting to look better

Also working on the cooling jackets

It takes ages to do it correctly

I bet this would get a lot of interest over on Greenhulk.
Them GPR boys are always in need of bigger and bigger bores.
Will you go over 90mm ?

 

[waxhead]

Not sure just yet
I was just thinking of making some and putting a 1200cc 2 cylinder in my superjet for kicks
I have the use of a 4 axis mill to make the stuff if i want

Wax, that is so cool! You have access to a 3D printer. Could you film the printing in action then speed it up and post the video? What do you do that you have such equipment at you fingertips?

 

[waxhead]

I teach computer aided drafting at a high school so i have access to all the universty machining equipment
so 3d scanners and cnc mills and 3d printers
I could actually get some ones cylinder and scan it then just tell the mill to make it

Well close to that it take a bit more work but you get the idea

 

[sflsurfrider]

why "scallop" the outside walls adjacent to the ports? it seems itd make them thinner and more prone to crackage.

 

[WaveDemon]

what program are you drawing that in?

making it so a b pipe would work would be a great alternative

Wasn't Bonzai Bob running his sans power valves.

Just the way it turned out
its a good point and easy to change as well


Im using solid edge to draw it

Yeah i think the b-pipe idea would be a good thing and make it easier to get a pipe in there i am going to pursure this idea more

There are many copy shops around the US that offer 3D printing. In particular, last year, on Lawrence Expressway in Santa Clara I just happened upon one. It is becoming more common . Do a search under "rapid prototyping."

 

[dbrutherford]

Wax that is pretty cool! I did AutoCAD for years, I know how much work you have in that drawing!
