chamber design. I'm stuck, please help!
my lonesome have been working on a set of mufflers that don't sound like fecal matter. I am having a difficult time finding just the mufflers (race mufflers). I DO NOT want an entire exhaust system. I do have the capability of fabing up mufflers, I have custom made equal length headers to an x pipe thus far. I DO NOT want the mufflers to have those two little connections keeping them together. I will be making this a side exit.
The motor is a carbed 5.5 lt small journal sbc. Should be able to make power to 7800 or so rpm.
I am looking for the highest frequency/note/tone/pitch I can get. I very much enjoy the higher, crisper, cleaner sound the european v8 makes. I hate with a passion the rumble of the harley/dumptruck American v8. I have heard flowmasters on these cars. I don't know if it was the particular flowmaster series or what. But that m3 was a dumptruck. I am trying to avoid that.
Sounds like a chevy small block doing a dyno pull to me...
amazing high frequency sound
Here is a cutaway of a corsa muffler.
I am rather sure that the chambers in the muffler can be designed as such to reflect frequencies to cancel out the unwanted frequencies. I just can't find the math anywhere to determine the dimensions of the chambers.
I am working with 17.9 inch long primary tubes that are 1 and 5/8 in diameter, they go into a 2.5 inch collector, that then goes into a 3 inch x pipe, that will then go directly to the side exit mufflers. I am keeping it as short as possible to help retain the sound I am after.
This is what I am avoiding.
Same motor different car different mufflers...
So does anyone know how to design the muffler to achieve this? Or designing a resonator to do this? Or simply the chambers inside the muffler to do this?
I am so stuck. Also I don't think a helmholts resonator of any kind will do the trick. that would only cancel out the freq. I think this is more like a musical instrument where the sound entering is not going to be the sound at the bell of the horn coming out.
Try searching "SuperTrapp" muffler. Some configs. have a higher pitch sound.
