ESE's works engine tuner

guess about the conrod everybody seem to know better it than we described !

ok thanks very much

[Jannem]

In any sim the STA number for the Ex is basically useless,as lifting the port floor and increasing the bottom corner rads has way more effect ( positive ) on eliminating short circuiting and increasing the duct velocity.

Is this typically the case with single ex. ports as well?

[Frits Overmars]

Yes

In my above post I beat the system .

Developping a Ryger
Is Ryger a fairy tale?
snip...
Initially it was mr. Ryger
snip...
mr. Ryger himself
snip...

I have no comment to make on the viability, or otherwise, of the Ryger engine, and, just a small point, but I thought it had been established that there is no-one actually called Mr Ryger?

[peewee]

i thought ryger was a real person. now you say its only fictional character ?

[Muciek]

He had a account here for brief moment if I remember correctly , there was some problem with something (posting or account approval) and then it all went go as it is now.

" At this moment, there is no reason, not to be proud of the result we have achieved till so far."
And there is the big issue with all of us Luc.
You may be proud,but all we have seen is made up graphs and complete rubbish so called " back to back " data plots of a Ryger Vs a KZ.
Any data plot should show a real KZ making at least 45Hp at 13500,it doesnt, so its bullshit.
If we were given just ONE real dyno sheet of some believable Ryger result, we would all clap and be very happy for you and the future of 2T in general.
Your move.

"He who thirsts for an answer must first stock up with a lot of patience".
A prophetic observation from Isaac Babel the Russian author, I guess he didn`t have the Ryger engine in mind for he was shot by Joe Stalin for exposing some of the secrets the paranoid Russians wanted to keep from the free world. Makes you think though!

Not to call Frits out on this, but when Frits drove Ryger kart I seem to recall his ride review seemed pretty positive

[Jannem]

If Ryger delivers it wont take long for it to be banned from racing. Then what? They better have a bike manufacturer lined up to bring it to the open market, where restrictions do not exist.

[Jannem]

With the importance of blowdown and transfer STA over the traditional angle*area/cc, has anyone developed a similar "rule of thumb" graph showing blowdown and transfer STA vs. peak power rpm to help choosing the port timings and areas?

[Jannem]

It's been mentioned several times that the transfer entry radiusing to the bore (see pic below) is worth proven HP. Does that area get masked by the piston, when transfers begin to open? (In RSA, where it originates from.)



Below is supposedly a RSA factory piston. The pin plug has been discussed before, how about the modifications? Is that big hole a dead end lightening one?

Developping a Ryger

Yes yes let the hate flow through you. You keep calling out the established professionals (we all know who you mean), even though you still have zero races under your belt. Doesn't Mr. Ryger get sick of your unprofessionalism?

Re the cost of running a KZ. I don't think the high level teams really care much about cost, as long as they win. Could be good for the lower level teams though.
