ESE's works engine tuner

Queer shit in Mikes MB engine? Its that lanky b'stard that is on the outside I'd be more worried about

That's a pretty cool slippery pipe gadget. Wonder how strong the servo has to be to pull the pipe esp as the header needs to be sealed so some friction is inevitable. Perhaps it doesn't kick in till 4th gear as trying to keep up in lower gears would surely be hard. I wonder how quickly it would respond during gear changes? I mean you can imagine peak revs then bam you change gear, revs drop & try to pull out of it with a short pipe.

Once you guys bulk up that hole a bit THAT would be a good engine to have.

Chambers has sorted it ................ I expect with a little more fiddling he will get all of the over rev back too. (24mm OKO carb)

Slippery Pipe



The Blue Line is my current engine. the other lines are tests done with 20-40-60mm expansion pieces in the mid section.

All the extra length did was flatten the top and did not give any extra power range at the bottom which is what I was looking for.

So from this experiment I am unconvinced that a slippery pipe would do much.

Sorry? so you've lost 5hp by adding 20mm? with no other changes? I'd question the pipe's integrity?



What did Chambers do to lose the dip? Ignition adv? Looks very nice.

I would guess that the 3 lower graphes where done some time ago .In the build up to the engine he has now

again would guess that the ignitech had something to do with it
got that one wrong
It was a new pipe

How about a variable exhaust header. This one allows 25mm adjustment

Google translate says "a new control to include inflammation of RTD and the like" Thanks Google.

Cagiva ran a system in the "lil Jon" days which extended the header pipe with a hydraulic actuation at huge pressure (1500psi) the pump allowed the header pipe to lengthen along the lines of 20mm extra or minus length .I guess they shorten the header length in operation.If I can be bothered I have pics somewhere.
Of course the Honda water injection based system was much simpler.
Interestingly after intensive and exhaustive "getit" searches I have established that neither of these two sucessfull Gp teams (Iebeit one more so than the other) used Speedpros "special" Rod

Even just looking at the 20 and 60 lines there is not much difference between them at the lower end, maybe 200rpm.

That's quite scary as I think it is a very close approximation of where my bike is at, lower in the rev range of course.

Hell, a picture being worth about a grand in word money I shall illustrate:

I think that is the best looking readout I have seen from you guys.
Now, how will it perform on the track?????

Whats your guess ..............

NedKelly at the last Taupo TRRS



And Neds new project...........



Team ESE are going to try their hand at 100cc water cooled.

[goose8]

Is it a rg100 ?

Time will tell. I will be interested in throttle response and driveability reports. If the graph is anything to go on then I think it should run pretty dam good. The graph looks like a mix of my when run with an RS pipe and then run with my TZ pipe, the mix I hope to develop into my bike.

Neds bike looks to be in the same state as mine. Is that the chassis someone in Aussie was selling a while ago???

[wobbly]

You guys will of course be putting the sprocket centerline in the right place to get some anti squat, and keeping the front of that engine up high so the angle wont be too steep with a dead straight rubber manifold holding the powerjet carb.
If the static angle is too acute, the fuel in the bowl can uncover the powerjet entry port - it goes lean and goes bang - been there done that.

Errrrr no ....... ........ but we do know whos got it.
