FX 25 mods for 2548
Is it "legal" to drill out the muffler stinger on a 2458 engine? will this increase performance?
It is legal. Most people that I know remove the baffle altogether and drill out the stinger enough to get rid of the internal flashing It doesn't increase performance much, but it does get people closer to the 14500 rpm max. Some engines can make it out of the box and others can't make it with the muffler mods and 30%. I'm one of the non engine geeks which doesn't make it with the mods but I get to about 13800 on a good day and 13600 on a bad day. The plane seems to perform well enough for me. If you haven't tried it out of the box yet, I would suggest you see what it does with out the mods since fuel pressure might suffer a little.
