[checkride]

Today decided to fit and weld on the Injector Bosses for the new engine. Monday will cadmium plate the intakes and fit to the motor.

Hi checkride where did you get the injector bosses? I am also looking at installing fuel injection on 2200 engine.
Thanks

Any updates on this fadec setup?

[lessersg]

Not on this Engine, has since been sold. Will be doing a Rotax 914 and 912 ULS very soon will continue this thread . Autronic ECU, EdgePerformace Fuel Injection, Big Bore and performance CAM.

Some eye candy.....

More candy....Lets hope my result turns out something like this. I'm doing the 914 converted to EFI. 125HP, with CSU. Then going to do a 912 ULS big bore , EFI and performance CAM- non turbo 120 HP.

Looks quite good - but you have to ask yourself why Rotax redesigned the entire core engine for the 135hp 915...

[lessersg]

I have no clue and neither am I interested in the 915 as i know what they went through in testing and designing the upgrades for the 912 and 914 . The development of these upgrades have been tested and tested over and over again in some extreme conditions. The 915 is still in the infant stages but I speak under correction.
912 STI 158 HP engines running on some heavy Lift Gyro exceeding 1500 hrs and more. I think they are being used on some military machines, camera sensor ships ect.
Some have been stripped down every 500hrs , no issues yet.

Maybe they needed more power and didnt know how to do it

On its way Fun and Games...

So its been a while ....and its done. See attached . If anyone is interested in more information drop me a PM.

So the plane has been flying for about a year now . In this time we have made some changes to the cowlings, firewall forward layout and a lot of testing and flying.

We did a good few hrs taff testing....you know the wool and airflow thingy. Have video but cannot upload here. Basically as far as the cowl is concerned we had to reduce the airflow going into the cowl by at least 2/3rd. What was happening and why we were having a cooling issue is that the cowl was being pressurised. As we started reducing the airflow into the cowl the temps started dropping by at least 30c . This was oil and coolant. Now we have a very happy Turbo charged engine with Intercooler. Aircraft lost 6 kg on the nose in total even with the small changes to the cowling.

So now that mechanically she is perfect, last part of this whole project is re-molding the cowl to remove the front chin. Inspection hatch on top for water and oil. So we will have a mold at the end of this and a Jig for the engine mount. Happy days for out J 400.

[lessersg]

That's now two done in SA both with Rotax 914....

[lessersg]

More flying with our Happy Jab...nearly 100 hrs now . We did 4 .5 yesterday some was climb testing again, making some small adjustments to the cowlings. But she is happy up high, low down , slow, fast etc. Have to calibrate Fuel computer and AFR sensor..... New molds for cowl soon, then respray....feel free to comment if you like LOL...
