My buddy's DA50 with Slimline pitts turns a BME 22x10 at 6400 RPM near sea level. Mine turns a Bambula 22x8 at 6900 near sea level. The MSC and Bambula are around the same static load from what I've seen on other people's numbers. Your Menz looks a little low. I've heard the Bisson is a little more restrictive than the Slimline. I'd also cut the small ends off the stacks, easy 200-300 gain.
The stock DA muffler is lighter than the slimline not sure about the Bisson. Your numbers would go way up with stock DA but so would the noise. Also looks pretty bad when cut up the left side of your engine cowling.
23x8 Mejzlik is around 6600-6700 if I remember right. 22x8 is around 7200-7300.

Hey guys, new to gas and have two flights on my DA50. The engine has about 5 gallons through it, and I am running 50 :1 Amsoil in it right now. It will swing a Menz 22X10 @ 6250 and a MSC 22X8 at 6900. This is with a Bisson pitts.
Do these figures seem about right?
Also how much would I gain by going with a Stock muffler? And lastly what could I expect a Mejzlick 23X8 to turn at?
Thanks Alot!!
