ESE's works engine tuner

[F5 Dave]

I imagine he wants to fit it inside the cases, because, you
know, why make it too easy?

[wobbly]

That length guide for a 12,000 rpm reed intake tune is the 3rd harmonic.
In that scenario the intake creates a + pressure ratio at the reeds , just as the case goes - from the piston rising.
This tuning opens the reeds very quickly , with + on one side and - on the other.
If tuning near peak Hp the reed setup is limited , just as a RV is limited by the length of available carbs , the rubber manifold , and the reed block or RV cover length.
Everything is being done now to get this length down , for example , by recessing the rubber manifold into the reed stuffer.

Or just throw the carburetor / throttle body away.

Vacuum operated gibs?? why are they called gibs?

I think in this case one refers to a T-shaped linear slide bearing which is usually called Gib.
But of course I hope it refers to Josiah Willard Gibbs Quote:
"The greatest amount of mechanical work which can be obtained from a given quantity of a certain substance in a given initial state, without increasing its total volume or allowing heat to pass to or from external bodies, except such as at the close of the processes are left in their initial condition.

Aha, I bet this was when he, Maxwell and the Invisible friend was trying to trick entropy?

Not sure if you are pulling my leg or not.
The single sided Sliding Gib could be operated via vacuum or as I did with a sevo run off the Ignitech. Separate throttle body.
The two sided Slding Gib can not as it now becomes the throttle body as well. In the interests of just getting my 360 up and running Ive just connected the Gibs direct to the twist grip. Ultimately these Gibs should be controlled via the ecu. You tell the ecu what you want (twist grip) and it juggles the Gibs to suit.

No, I only thought that if the gibs are also the throttle it would be nice if there was an rpm function to the opening. But I didn't know how it worked.

"gib" is a name for a style of captive sliding device.

[andreas]

Thanks TZ.

[Flettner]

Thanks TZ.

Andreas, a curved sliding Gib, seen here fully in the fully open position.

It really is an excellent invention.

[F5 Dave]

And still nothing to do with the BeeGees .

Neat so with it fly by wire from the ECu you can then have traction control, or idiot control,wheelie control wet slippery etc right down to gps of parts of the tracks.
if anyone is in doubt of the validity of this drive a late model manual in power ,eco mode etc
its not the power output of the engine that generally changes, its the throttle response to the inputs that do.
In most instances it just opens the throttle further for the same accelerator input.
As a team owner You could also use it to make your number 2 driver slower.

Might even help silly old bustard's like me be a little more competitive again, i.e. not so slow on a trail ride.
The ecu throttle with sliding gibs is more useful because there is a difference between throttle opening and gibs valve timing. At the moment the opening timing is just set via the small tooth belt pully tooth numbers.
Its a cool piece of technology, so long as Im the only one entered in the event with it
