Ok Guys…. Need some opinions here. I am just finishing up an installation (gut and reinstall …..) on a customers SM F-15. Having no install experience with RAM/T engines I am a bit concerned about the pipe/engine install. Usually, with a jetcat install I set the nozzle separation to the bellmouth at ½” for max thrust and pipe cooling. As you can see below, I have the engine about as far forward as I can and the nozzle still enters the pipe about ½ to ¾” The pipe is actually sticking further out the fuse at this setting than I would prefer. The question is….. Since the nozzle is about twice as long on this engine, can I slide the pipe up further? Leave it as is….Or, should this setup have the same pipe/bellmouth clearance I am used to with Jetcat???

call FTE or Carlos, they should know

my jetcat P-80 manual wants 20mm gap between tailcone and start of tailpipe.

i think you may have to move tailpipe aft and cut off some of the tail end.

Hi Todd,

I've been flying mine with a RAM 1000 with close to 80 flights. I think you will be fine the way it is (in the picture). I originally flew mine like this for a dozen or so flights but eventually moved the engine forward to where the nozzle was even to 1/8" forward (out) of the bellmouth. The way I had to do it was that tail pipe was as back as it will go (flush with the FG cones in the back) and dremeled out the center seam (inside the inlets) to almost nothing and slide the engine all the way forward.

I believe this is the best setting and the plane really comes alive.

Hope this helps.

There is actually a short tailcone that was made for this application. They don't produce them anymore, but I would guess that Carlos has a few lying around.

I have set up a Ram 750p like that in the past and it worked out fine. I would go with it.

Mines set at the beginning of the exhaust bellmouth

Thanks guys.... I guess I will leave it like it is and if the customer chooses, see if he can find the shorter nozzle......

Few more install pics.....

Forgive me Todd but I have never seen a thread titled "I need help" that was created by you.

.... Trust me..... I need lots of help
