RE: Using car engine muffler on a Four Stroke??
Yes I still have the manifold
I actually run the engine without the muffler after I lost it....I would say it delivers a bit more power...or maybe it was just the sound..which is about the same that with muffler....but the engine didn't work well at the transitions...and I saw lot of bubbles in the line, so I think it relies on muffler pressure to workt well and not just by suction... Another thing is that it is too short for the plane...the plane has a real fat fuse.
I thought it would be a good Idea to try this muffler since it's just 9EUR.... an ASP muffler would cost about 20 I think..and the original about 30...so I do my math hehe!...
How many times have you seen that the rear cap of the muffler...where is the gas exit...begin to turn???
Now I have 2 4 strokes and in both of them the rear cap turns and gets oily and black =(.
