Coolant radiator

[Eric Hendriks 0]

Hello

 

I have a KF 3 with a Rotax 912 and I am looking for a way to mount a radiator inside the cowling.

How are the radiators mounted in the Avid

I don"t like the way they are mounted on a kitfox and the other side is that if I have to order the radiator and pipes from kitfox it will cost me a fortune to get the parts in Europe.

 

Thank You

Eric,

I don't know anything about the 912 setup, but the guy I got my Subaru from had it in a Pelican, and he mounted the radiator inside the cowl, more or less, by hanging it at an angle from the lower firewall at the rear opening of the cowl. He said he made a tunnel inside the cowl to feed fresh air to the radiator, and to keep the hot exhaust pipe air away from it. He extended the tunnel past the back of the radiator and narrowed it there to increase the outflow.

Hope this gives you an idea.

Look at how Rans does the radiator on an S7 with a 912. I'm sure this could be copied successfully with a Kitfox using a locally sourced small automotive radiator.

I doubt mounting in the cowl will work due to airflow and space considerations.

Got any photos or drawings of the Rans setup?

No photos, yet. It's basically a belly scoop with the radiator making the bottom panel. Air is scooped in then forced to exit through the radiator.

My MK IV has the radiator below the oil pump and it works very well.  Here are some pages out the  manual .  I guess I did not take many pictures at that stage of the build.

Rans S7 setup...

I have a MK IV cowl that was to be used with a 912.  Here are pics of it.  I bought it to go on my Kitfox 4 project.  Maybe some day I can get back to working on it.  Don't know how the radiator mounted though.  Jim

A Mk-IV Avid 912 mounted the radiator in the chin of the cowling.  The 912 FWF came with an additional fiberglass scoop to glass onto the face of the cowl to give more room in this area.

 

Here are a couple of examples of Mk-IV style cowls (open).

 

 

 

And one with the cowl closed...

That looks like a better setup than outside the frame, or behind the exhausts.

Thanks for the photos,

Hey, I know those guys!

Yup, I bet you do...

 

The first two photos were from our "Journey Trip" this past spring to Kittyhawk, NC.
