I have been reading threads about guys putting on Flowmasters and such, as well as the comments about the V-10 being a different beast all together and not sounding like a V-8, B U T, nobody has gone to the trouble to try and explain just what the V-10 does sound like?
Is it louder then a V-8, quieter then a V-8, smoother then a V-8.
Personally I cant see it sounding much different, but I am curious to try and find out before I sink some cash on an exhaust system I may not care for in the end so to speak....hahahahahahahahaha

 

sounds like farting! Some, myself included like the sound but others hate it, it will never sound like a V8.

 

A horse poot...maybe.

I have been thinking about trying several things. Currently I have the Flo70 single in/dual out, but a guy in town said he would install true duals with 3" x 3 ft glasspacks for $175.00.

I'm gonna let him do it.

I'll let you know.

 

Would you discribe it as a long smooth rumbleing type, hahahahahahahhha

I cant believe I am going here on a public forum.......hahahahahahahaah
You have to admit, this is rather funny to compare a truck exhaust sound to a human fart.....hahahahahahahahah

 

I meant equine flatulence... Is that better?

The sound is unique. Almost like one of those Indy cars, sort of.

 

The Indy car thing is what I keep thinking of........back when they were still using the large v- style engines, wasnt that like the 60's or 70's??..........Im going for the Flowmaster soon and was really curious what kind of answers I would get.

 

Anybody got any sound files to put up?

 

Anyone have a Banks Power pack? I'm looking into getting one rather than spend time and money getting an intake and filter, computer programmer and changing exhaust again. I want to get the whole package. I wanna hear one before I buy. Sure those Torque tube headers sound pretty good.

 

The V10 sounds like a hi-performance import on roids!!!!

 

A co worker gave me a ride last night to where I park my PU,. He has a Dodge with a v-10, and a flowmaster exhaust. When I heard it I told him his exhaust sounded pussified when I got out. First thing this morning, I told him I did not mean to be offensive with my comment on his exhaust, and that I knew the sound he was looking for and expecting, but it fell short with the v-10. Maybe smaller pistons. not sure, but the tone is not the deep throated sound most good v-8 exhausts have.

 

On my road trip this past Tuesday, and the fact I got 15.9 MPG, I now wonder if I should even mess with tryin to get anymore fuel mileage out of her. I dont think Ive seen documentation of a vast improvement in fuel economy by going to Flowmaster. I know I didnt gain anything noticable in my Expedition, although it did sound nice, but I dont think I will spend that kind of money again just for the sound.

 

Briggs and Stratton 1 cylinder 4 stroke @ 1000 rpm = 500 pulses per minute(PPM) or 8.33 pulses per second(PPS) PPS = PPM divided by 60(seconds)

Four stroke motors fire every 720 degrees of rotation or every 2 revoloutions

@1000 RPM a 4 stroke:
2 cylinder = 1000 PPM/16.6 PPS
4 = 2000 PPM/33.3 PPS
6 = 3000 PPM/50 PPS
8 = 4000 PPM/66.6 PPS
10 = 5000 PPM/83.3 PPS
12 = 6000 PPM/100 PPS

What you see here is a FREQUENCY of sound and power pulses at 1000 RPM.
The Frequency increases with the number of cylinders and as RPM is increased.

Please do not confuse this frequency of power/exhaust pulses with the audible tone frequency of the sound wave. This frequency is just showing you how many times per second a SOUND is being produced. Other factors determine the tone of that sound.

The effects of audio attentuation by a exhaust system are much too complex to go into here. However for the sake of information here are some, not all, other factors:

At the moment of exhaust valve opening, the Noise Level (Sound Preasure Level) measured in decibels, is very high. The exhaust system is designed to evacuate the hot gasses to the rear of the vehicle AND attentuate the noise down to lower decibel levels.

The length, shape, catalitic converter design, muffler design, material, and mounting of the entire exhaust system all are able to change the loudness and tone of the sound but not the frequency.

Valve overlap and timing do have an effect on tone that can vary. from fairly hollow low tones. to high pitched sharp crack sound.

Some folks seem to like a raspy sharp crackling sound and others like a deep bassy throaty note.

Lots of money by a few trying to make big cool V10 sound like V8s.

All the major car companies have engineers and sound chambers to set the exhaust tone to be within EPA decibel standards and try (only try) to create a unique or classic exhaust note.

Owning a SuperDuty sure is fun ain't it?

 

could that post be any longer?

 

While it's true that a 4 stroke engine fires all cylinders once every two revolutions, and that the above calculations are correct ...
... incidentally, a 3 cylinder has 1500 PPM/ 25 PPS ...
... there is more to it.

Most 4 cylinder motors fire a cylinder every 180 degrees of crank rotation on an evenly timed basis.

My 3 cylinder '74 Triumph has a crank with 120 degree throws so it fires a cylinder every 240 degrees of crank rotation.

The thing that makes most V8 s sound so raspy is that when you look closely at the crank throws and the cylinder bank angles, what you get is a very uneven firing orders with gaps in the sequence of both the left and right banks. You might have 1 left, 2 right, 1 left, 1 right, 2 left, 1 right ... and so on. When the Nascar guys were using 180 degree headers that paired cylinders from opposite banks with cross overs under the motor, they sounded more "regular" or "even" in thier fireing ... but it was in the headers.

The V10 are like two straight 5s with a narrow angle between the banks, they have their own sound.

later ............

 

Afraid I never got around to recording the finished installation. But I did get a sound clip of "open headers". Links to .wav files at the bottom of this page: http://makinhay.net/nomo/f350/banks/banks.html
