ESE's works engine tuner

[lucf]

Avoiding my question Luc? (edit: i can see you are online at this very point when i posted this)

Sorry, No answer in a climate were so many are shouting to me as if I 'm a bluffing dog !
For sure it is in the publication !

I answered that same question here some time ago. Here is the corresponding drawing once more.

Sorry for the repetitive question. I struggle to get meaningful results from searching and I'm only through reading the first 250 pages. Huge amount of information to absorb.

Thank you.

Edit:
In the same lines: Do you measure the deck height from the middle of the piston top radius? In practice, measure piston height from skirt to middle of the radius and do the port height measurements from the bottom of the liner against the skirt to get accurate reading from the caliper?

You're welcome Jannem. I know it can be a quite a job to go through the lot here. Personally, I never seem to get along with any forum search function .

Were the people who bought the first versions of the ryger refunded?

As long as you have no independent results to show, it's called bluffing. I don't know about the dog part though.

Btw I just saw I was right about the track record, it was at Eefde. Such an important circuit in the karting world, lots of high level KZ drivers go there... . What laptimes are you getting at Berghem, Genk or Kerpen for example? I mean if you're serious about competing with these engines you've surely tested at a proper track by now right? I'll go first: with a Rotax Max I went around Berghem in 46,28s a couple weeks ago, I guess KZ's are at least two to three seconds faster there. Here's a picture:


Now you might be sceptical about that picture, because it could have been faked somehow. But the difference between your claims and mine is that mine is actually within expectation. People expect a good Rotax Max kart to do a laptime like that. If someone is still sceptical I don't start calling them names and say "you'll see"! I either provide more evidence or accept that this person doesn't believe me. See, it's not that difficult. Now it's your turn, what kind of laptimes do you get on a relevant track like Berghem? Or do you have plans to go testing there?

I'm not trying to tick you off, I'm just trying to explain WHY people here are sceptical and would love to see real world results that we can actually compare to.

I know this has been mentioned here previously but just in case it's been missed: forum searches never seem to work but a google site: search usually gets results. For example, to search this thread for posts containing the word "ethanol" you'd type (or copy/paste) this:

A 7 thou plastic shim at 45 deg is very close to 0.25mm and works very well on model engines. It is a thin strip about 1mm wide. Other times I use a 4 thou shim and sit it on the piston crown and poke it to the side of the ports. I do this on the induction timing as well with the 4 thou shim. And then compensate for the .1mm radial movement. With the MB engine I measure all from the centre of the crown, and use light to see the port. Seems to work quite good as well. Like everything, there is always a little bit of ambiguity around the timing numbers any way. It is good enough to get a comparison with.

No, nobody ever bought one....

Thank you.

The Kb search function needs a few paremeters spec'd
try this
First start from the ESE page to search the thread.
Then hit advanced search
Then search single content
Then Make sure the bottom dot is in post rather than thread.


You can also select the author whose post you wish to search for instance Wobbly, Frits etc
by searching under their user name or multiple usernames.
this narrows down the number of posts to go through dramatically.

or you can use Google with a few key words that you are looking for but include "ESE works Engine tuner" you need " " the so Google only searches those words with the ESE thread.

I use google custom search engine for looking up older items (items just posted don't show up directly)

This works really well.
I keep a tab open in my browser at this page

Lucf,
i would imagine that you too are unable to speak openly about this engine due to legal implications which must be really frustrating for you as well as those who are interested. Its been such a long time since this engine was first spoken about, with great anticipation , many people have waited for how the engine works. Im sure i remember a statement about this being a design not for the big companies but for the 2 stroke community in general..... Thing is, governments bringing in laws which will eventually kill the 2 stroke/ 4 stroke whether it runs clean or not and industry which controls what we buy, now focusing on electrically operated engines time is running ever shorter. Cant Mr Ryger himself speak openly about his engine? whats holding him back?
regards, breezy

Honestly Katinas, no disrespect.
But your engine sounds really tired.
It seems like it need huge,,i mean HUGE increase of advance(ignition)

Rgds.

Yes, thats right. I started testing this engine with std advance, but then released that it needed much more ( 10-15 degrees, so surprised ). When made bigger stinger ( from 23 mm to 29 mm) found that much better power with std. advance, but from 0 to 6000 rpm. much worse. This video with std advance.

[Flettner]

Yes, poor Luc , between a rock and a hard place. I guess he is hamstrung as well, I just wish Ryger would hurry up and conker the world, or not, just do something!
It's almost too late now anyway.

[katinas]

Thanks Luc for your open words, yes this is very complex and after 3 month testing, sometimes, thought would be so nice return to std. engine.

Yesterday tested again:

Modified intake plate, cut hole for C port, and power was the best of all tests like ( 4-5 hp plus ) , but suddenly, when changing gear - BANG . Stopped, no compression, but easy rotating. Amazing, that happen at the same place where first piston seize in April. This time piston ring break down . So ......

Hardly too late in competition everyone wants the latest and greatest .................but got to have the runs on the board first. IF the engine lived up to the hype last years champ would be cutting laps around tracks with a mountain of youtube clips to look at.
