Lamey Cylinders **NO MORE**

[wsuwrhr]

The cylinders have been made "in house" since '97 or so, maybe even earlier. I can promise you that.

We have full manufacturing capabilty with 2 CNC mills(with another one on order, due in the shop May 19th), 1 bar feed CNC lathe, and the 5-axis mill you were referring to, which is only used to port the 4 stroke ATV heads and the exhaust ports on the GP cylinder. We are able to make all of our machined parts in-house. Including all the PV parts for the cylinder.

I did not know about the 5 ports part. Something new learned every day.

I agree for top end the angled ports may not make that much difference but for us mid to bottom end it does as it helps the flow by directing it to the ports faster which gives us the snap we want.

He is making more and more in house and bought a full CNC milling machine with some sort of angled adapter so I’m not surprised he did it.

the out come will be intresting

The 5 MM stroker cylinders "uncover" the angled wall I think you guys are referring to anyway. So no matter what it has to be done.

We have been CNC machining the top case to match for a few months. The big bore cylinder will need this mod to run correctly as well. We can do this for anyone who wants to send in their top case.

Brian

When you cut the case the gases get there quicker with less distance to travel
we did an engine and cut the cases to allow the extra ports to come straight down
the major gain was the low end throttle response it hit like a mother off the bottom
and it gained a bit extra up top as well
I wouldnt build another 7 port cylinder with out doing this

 

[wsuwrhr]

The cylinders have been done on a CNC machine since '94 or so.

Supply won't be as big of a problem either, those problems were mainly due to the time the castings took to complete and the problems encountered with the casting process.

Brian

Why wouldn't he CNC it? Times have changed and this is the way the metal industry is heading. I think it will be sweet, maybe he'll be able to produce them faster now.

 

[wsuwrhr]

The casting COST is cheaper than the billet chunk, that is for sure. Everything else is more expensive.

Certainly not faster, I can order material and be machining cylinders in as little as three days, it may take two to three weeks to get castings, with alot more effort.

Brian

my understanding is that casting is cheaper to do, cheaper for materials, and faster. billet is for bling.

 

[wsuwrhr]

Exactly true.

Well, I got 2 of those cylinders on order. The problem before was that Lamey was sub-contracting another companie for the castings and ,of course, never delivered on time. Now, all will be done in house with a quick turnaround and consistency. there will also have two diffrent versions: standard 85mm , 86mm bore cylinders and the 89mm+ bore cylinders that will come with a custom head.
Personally, I am looking forward to this progress. Also looking forward towards that new 12mm stroker crank !!!

 

[wsuwrhr]

Chrysler, Chevy and Ford pump out THOUSANDS of cars a month, each.


We may do 500 cylinders in any given year.

I promise you guys will be glad we made the switch.

Now that makes sense! he's binging the work in house to be done on equipment he either owns or is familiar with.

Casting is cheaper and faster. I don't ever see chevy, ford, or chrysler pumping out billet engine blocks.

You're welcome Aaron,

I will do my best to answers any questions anyone will have. What I can't answer, I will get the answer.

We have two cylinders now, the small bore and the big bore.

The small bore billet is similar in design to our cast cylinder and uses the same sleeve as the cast cylinder, with factory exhaust and cylinder head dimensions.

The big bore cylinder starts out in the upper 80 MM range on into the 90's. This cylinder uses the factory exhaust pattern but uses a different head bolt pattern, the cylinder head/correct domes for your application will come with the cylinder package.

Both are available with or without power valves and both cylinders can be configured for any stroke from stock stroke on up to 12mm stroke.

The small bore billet is comparable to the cast price, I think it is little more, but I am not sure.

I would rather you call the shop for that information because I don't handle that end, but if you want me to, I will find out and PM it to you.

I am sure this site will frown on me posting prices.

Let me know if your have any other questions.

Brian

Thanks for coming here to answer questions.

I think my first question is "how many dollars?" I am sure the answer varies depending on questions I don't even know to ask...;-)

Why would this site frown on you posting prices ??

For riders by riders is the motto.


BTW, thank you for coming here and explaining the magic that is the "Lamey".
One of these days I will have one.

 

[wsuwrhr]

Oh OK.

Thanks Boris.

I haven't looked over the posting rules yet.

Most internet boards frown on their site being used for commercial purposes unless you are a site sponsor.

If it isn't against the rules, I would list the price. I still don't know it though, I will have to find out.

When I spoke to kyle over there, he said that you cannot use the big bore (90mm+) cylinders on less than a 6mm crank. Is this true? Any way to use it on a 5mm crank?

 

[wsuwrhr]

Kyle knows what he is talking about, I don't know what the reason is though.

I would guess that the 90MM+ piston skirt is long enough that it will contact on the downstroke, the bottom of the piston may be able to be trimmed that small of an amount, but then it may freeport.

I don't know the answer, but I will ask tomorrow.

hey Brian, welcome to the X. We do not frown upon you posting pricing or info about your cylinders as long as you are not just spamming. We encourage interaction from engine builders, suppliers etc etc.......... We sometimes need answers to questions that you can help to clarify.... In turn, we may end up buying parts through you or from a builder/supplier. It is a win win situation for all.

Again, welcome to the world of misfits., I mean the X!!!

[wsuwrhr]

Glad to be here and thanks for the welcome.

I hope I can be of help to anyone that needs it.

I am sure plenty of you guys know Dan has his hands full and sometimes he is very hard to get ahold of.

I would like to help out in any way I can.

Can you post a picture please
I was assuming that you were just going tomarket the bun cylinder it appears i am wrong and I am happy to be

I can understand the cast cylinders having issues and see why you have gone to billet now
I was worried that you would not be putting in a the extra transfers , actually i was told you werent
Seems they were wrong as well

 

[waxhead]

On another note
Are we going to start seeing triple exhaust ports in the new cylinders

 

[wsuwrhr]

DASA/Racer's Edge/Dan Lamey marketing a Bun cylinder? Are you serious? You must be joking.

I can post pictures of the cylinder if you like, but I can tell you right now it won't be of the transfers or water jacket area. I don't feel it would be prudent.

The big bore cylinder has a 5 port, it does not have the 7 port, Dan felt a motor this big wouldn't be necessary and he wanted more transfer volume.

But again, the small bore cylinder uses the SAME sleeve as the cast cylinder.

[waxhead]

Yeah that would be awesome
I would like to see it, out of interest only
I have my old cast 8mm pv engine that will be fine with me

I would have thought a bigger engine would want more transfer port area due to the increased gas movement

Unless you have made the transfer windows very wide in the 5 port cylinder but then surely that would be hard on rings

 

[wsuwrhr]

This is of the very first prototype cylinder. The exhaust isn't done in this shot, nor are the sleeves installed or holes drilled for the water passage into the water jacket.

All of the billet cylinders, and the factory cylinders too, will all now have the exhaust port finished on the 5-axis mill.

Nice looking programing
Good machining as well
I teach cad drawing and its good to see other peoples work

Thanks for the kind words. I worked my ass off to make that cylinder resemble the cast cylinder as best as I could.

It was about the same weight too.
