Wax cylinder

[robertg]

Just for the record, exactly how much is a lamey?

http://http://www.lenziparts.com/v1.0/Parts.asp
Lenzi sells them for $2,800.00 with pistons and a head.

Last time someone posted, Lamey cylinders retailed for $1,800 (that's with sleeves but no porting). Any stroke you want.

i honestly still dont see why they're so good? say you were to take a lamey and a stocker bored out the same, same port, same other a/m parts. what would happen?

or is it just the possibilities a Lamey has? it just has greater potential for greater HP?

I'd like to know, educate me:headbang:

There are seven intake ports on the Lamey cylinder vs. the five ports on the stock cylinder and the casting area up to the ports has a larger intake volume.

the
riva,R&D and lamey are the same cylinder

the able and the ada were billet cylinders we looked at that but hard to get the 7 ports in there like that

protec cylinder had more exhaust but not more or not much more transfer port area( the weak area in a yamaha is the transfer)

Never heard of the dasa but i would love to see a cylinder


These will look simialar to a lamey style
as well as be able to handle a power valve

DASA is Lamey...........

 

[#ZERO]

The R&D cylinders are non power valve and have exhaust side that looks similar to that of the stock cylinders. Also the base of the R&D cylinders is unequal lengths similar to the stock cylinders.

The DASA cylinder is the Japanese version of the Lamey that comes in a power valve only for 5mm, 6mm, and 8mm stroker crankshafts and yep same thing.

You can't add those extra transfer ports to an OEM cylinder (like others have said). So they'll never be the same.

If you're asking is it worth $1,800? Depends what you're building and how much you want to spend...

RIVA, R&D, DASA, and Lamey are all the same.
The casting has changed a little over the years, but the ports have remained the same.
I believe the casting is in the third design right now (but I think Paul would know more than me).
I was using a 1st generation casting this summer (smitty's old cylinder) and now I have the 3rd gen.

I think DASA is short for Dans American Speed Authority.

 

[Big Kahuna]

always wondered about that!!!!!!!!!!!!!

 

[bad93blaster]

is the ada cylinder priceing less or more than the wax racing goal price

 

[waxhead]

not sure how much they are after for an ada cylinder
is the ada a 7 port cylinder

 

[Mile9c1]

No, it's a 6 (4 transfers).

Here are some pictures of the ADA stroker cylinder since there not on the web site any more. It has four transfer ports and one extended length boosts port, set up for a 4.5mm or 5mm crankshaft or you could use a longer stroke by custom machining the domes. The kit included: cylinder, head, sleeves, head bolts, o-rings, and water fittings. The cylinder required installation of the sleeves and porting and would not work with the stock crankshaft. Also there were different versions for the Yamaha pistons or Kawasaki flat top pistons.

 

[jmeadlock]

That would be SWEET!!
BUT...how are you going to get the air into the combustion chamber?
I believe Paul has mentioned that around the 88mm mark (on yamaha and Lamey cylinders) the physics don't allow enough air to fill the combustion chamber.
I'm wondering if you (wax) have some case ideas or something that will cure this issue?

I thought he was saying something like:

"We can increase sleeve size but doing so lessens the volume of the transfer ports... we reach a break even point hp-wise @ 88mm with our porting"

So I'm thinking that if you make your own cylinder you could enlarge the transfer area, allowing more possible hp at larger bore sizes (assuming the crank will take it???

You can't just add transfer area, it has no where to go.

 

[SuperJETT]

You can't just add transfer area, it has no where to go.

Sure you can, you build a bigger cylinder that has the proper proportions of transfer port area to displacement.

 

[romack991]

if you are using the same crank, you can only go so big with the cylinder and transfers because bore spacing will remain the same and you still need the cooling through there.
