Help with In-cowl engine setup

       Remove this ad - become a site supporter!
Hey guys, hopefully someone can help me out with a little problem I'm having with my Topflite FW190 D-9 and mounting the engine and cowl.

I have a Bisson Muffler for my OS 61fx that I'm using and with the engine inverted, it'll stick out about 1/2 way through the cowl if not more, however when I flip the muffler pointing upwards, while leaving the engine inverted, only a small bit of the tip shows through the cowl.

I've flipped the engine over right-side up and this will work, however for some reason the engine is interfering with the cowl now. The plans say to mount inverted and use a header with a different exhaust and I'd like to stay inverted as that's how it's been setup.

I guess my question in all this dribble is:

Will the 1/2 exhaust sticking out cause too much drag, or does it matter if I run the exhaust up and out the top. (I know it'll be messy, but that's ok.. )

Here are 2 images of what I am talking about. (sorry bout the quality my cellphone is more a phone than a camera )

1st image shows how I would imagine they're expecting it to be installed and the 2nd shows the muffler pointing up..

Thanks for the assistance in advance.

You can buy "inverted" mufflers from Bisson which are designed to work with inverted installations. I wouldn't recommend using your muffler with the engine upsidedown, all of the exhaust crap will leak back down into the engine causing running problems.
