Lamey Cylinder Pictures Please...

[ATS_Aaron]

If you want a Dan Lamey designed cylinder, long stroke and seperate cylinders buy a 66E.

I have heard that too. I think it was Kyle at DASA that told me that.

I need a history lesson:

Dan Lamey used to work at R&D (I recently heard that Harry K of Group K worked there too??).

While at R&D Dan designed his cylinder? That is why some say Lamey, some say R&D?

What about the Riva cylinders? Are they Lamey cast cylinders too?

I heard the R&D pipe was designed for the R&D/Lamey cylinder and the package made nearly 150hp. The catch to that story is why doens't the R&D chamber clear power valves? Was it designed for the non-PV cylinder?

When did the Lamey cylinder come out? My guess is about 1996, because it used SeaDoo power valves and I don't recall those on a Sea Doo before 1995 (unless they were on a Ski Doo previously?)

Yes sir.

No sir, Dan ran the motor shop at PJS and when they went out of business, he started Racer's Edge, sometime around '88-'89. R & D sold the "Lamey" with their own name cast in the side(as a few others as well)

No sir

The original cylinders had no power valves. I still don't know why it was never "fixed" after the valves were added.

I will say '92, because that is what I remember.

What do you think?

What do you think?

Thanks. I find this information so cool.
I'm going to repost it in a new thread in the general forum. We're off subject enough here. haha

yes end of thread im not gona spy pics rather get the real deal ;>

 

[waxhead]

What dude?

tz125 had the extra transfers long before lamey ever used them
My point is they have been around long before the lamey cylinder

Im sure you know this already so its not really copying some ones cylinder

There is a lot of cylinder out there for this engine it would just be another cylinder out there

Like I said I have a drawing for this cylinder I have done myself I just never went into production

 

[Exile]

hey wax what is in yor product range so far??? billet case, cylinders, billet flywheels your always up to some cool stuff aussie action ;>

 

[waxhead]

Im not doing anything at all, im out of jetski stuff
I was going to do a range but when the market had a crash i decided against it

u

Not cool to request pics so you can copy somebody elses work.

Here we go again.:smashfreakB:

What I would do is purchase a cylinder get all dimensional requirements needed then sell the cylinder and make whatever I want.

I am a design engineer and designs are copied every day that’s what keeps us on our toes and keeps us thinking of new ideas.

You do realize that that Factory Yamaha used lamey cylinders in their Pro-Mod race boats in the 90's dont you. Also Lamey has dome R&D work for Yamaha.

All I am saying is that it is a 2 stroke cylinder, there are only so many ways to do it. Dan looked at a yamaha cylinder and improved it, you don't think that he took a good portion of his measurements straight off of the Yam. cylinder? What's to say Exile doesn't look at a Lamey cylinder and improve on that, he isn't even asking to measure one.
Calling somebody out as copying work by merely asking for pics shows how much you know about how much work is actually put into the design, please tell me what port timing, size, and tolerances he can pick up from a photograph then tell me how much of a proper cylinder you can design off that.
If you don't want anybody to steal your design, don't sell the product.

Asking for a picture is one thing. To say "I got a buddy who does CNC work and he can copy it" is another. If he wants to buy a cylinder, make copies then produce one is a different thing (Still wrong).

My only issue is the out right asking for that purpose.

No, a picture wont give you the intake track design and layout, will not give you the roof angles of the intake ports.

But guess what, that is my opinion. You want to post up the pics, go right ahead. I am not stopping you.

Design away.

didn't somebody do that already??:scratchchin:

 

[Exile]

wow this seems like i hit a nerve lol anyway the purpose isto develop a better cylinder than a lamey, jsut like the lamey is better than stock sure you must be able to even better a lamey cant you? always room fo improvement...example: lets say you have a manifold, you measure the stock air flow and desighn an bette air flow with testing and measuring from the base that you have i never even mentioned selling it this is for me personally i dont want to run a shop i just wana ride 24/7.

 

[Idok]

ok elaborate... each piston gets its own cylinder right next to each other instead of 1 solid cylinder unit with 2 heads if you can call it that... all i really want is a kickass stock stroke surf motor so paul told me non pv lamey 785cc flattop with bpipe msd enhancer single carb is the shizz it sounds awesome to me compared to a unproven dual cylinder?

exile..check out my avatar motor:

single 49 full spec
stock stroke PV cyl with FREESTYLE porting...all cnc..no race porting here

200lbs compression, pump gas on stock electrics


the perfect surf motor

 

[Exile]

WOW Idok u have a scary motor pv in the surf it must hit like an elaphant gun??? how is the maintanace on the pv motor and does anyone know if the xscream cylinder hits as hard or harder than the lamey/dasa... the thing is i live here in south africa so i will have to buy a complete motor cant just send my case over for porting haha you guys are very lucky to have so many expert builders here if you have a bigbore you are pushing your luck lol normally limited is where we peeps stop...

its not scary at all...feels electric, like a sewing machine

zero maintenance to the PV's

same motor..2 different hulls.....most of the time that motor doesnt even know its running.....I am expecting at least 3 seasons out of this topend, then it will go back for inspection and a fresh topend (if needed)


Rode with another local this weekend who has the Xscream stock stroke 865 kit (mine is the 785)...He said that the Xscream motor (currently at 827cc's) is WAY stronger than his DASA 920

he in fact termed the DASA motor a POS...said it was completely lacking in bottom end, but had a great mid and top.....



I rode the 827 and it was stout!



a few weeks ago I had the opportunity to ride back to back to back:

my Xscream 735
stock stroke NPV lamey running 240 psi
5mm ada billet with TL

the TL boat was the snappiest, but the X motor felt MUCH stronger than the NPV stock stroke lamey....





----the way it was explained to me...DASA's motors are ported for race, maybe they offer f/s porting as well.......not 100% sure

nor am I sure if the porting is done by hand, or by CNC...I know the Xsream porting is CNC done, which will make it 100% accurate 100% of the time

edit--to make this statement a little more accurate

Racers edge specializes in race motors....Xscream specializes in freestyle motors

what pipes are you running b pipe wet? or the xscream huge pipe thin?

At 100cc's less displacement and less stroke to boot?

Right....

It better be....your motor has power valves.

Especially with a stock stroke, there would be absolutely no comparison from a non PV motor to a PV motor.

Racers edge builds race motors....Xscream builds freestyle motors

Right.
