Harper,

Here is another one.  The difficulty with any forward facing injector is the limited space available forward of the injector.  Using a 90 or 90+ deg elbow such as Johannes has is quite popular.  The cowl scoop is much deeper in that case and from the outside will look more like a carbureted installation. 

The attached photos are of a set-up using a K&N conical filter inside of a fiberglass diffuser (not yet trimmed in the photo).  Alternate air is provided by rotating a ring at the aft end which causes the slots to open up.

There is a lot of variety out there in IO induction systems.

Harper,

 

i have a Lancair 320  with an IO-320D1B and a 90° forward swapped injector. I have not Chris´s cowling. In addition I use a small air filter box with bypass.

However I have to say my engine does not run very smooth in idle rpm. I  can´t tell this is caused by 90° injector design.

However the cowling looks nice J

Betreff: forward mounted fuel injection

 

How have others handled the intake for a forward mounted  fuel injection on a 320 with Chris Zavatson's cowl?  Do most people run a straight pipe from the cowl to the injector body (w/ a flexible component) , pipe with a screen or a very small filter housing?
