So let's set this straight on what gives it that v8 sound

Agreed, it was painfully obvious it was a V6 when he revved it.

I always thought the exhaust set up I had on my old V6, supercharged Grand Prix sounded pretty good. It almost sounded V8-like in some aspects but it was still a V6 sound in the end. I'll see if I can get comparison video just for fun the next time I visit my parents.

I don't understand this... my stock exhaust LS3 is incredible loud for factory exhaust which surprised me. Yeah, it's not as loud as aftermarket will get you but it's still pretty damn loud. Do you have the L99?

That's all, no need to be dissing anyone everyone.

It would sound like it was dying.... and again like mentioned before there is NO WAY with two cylinders off a V8 would sound like a V6. Again they are completely different engines. It's all about timing, bore, firing order, stroke length, etc., etc., etc.

I see what you're saying about a V8 firing without a couple of cylinders when you're working on it, but in my experience an engine in that state doesn't even idle well enough to accurately compare a v6 or v8 sound.

avd. Because guess what? I have one. All I was doing was clearing up somethings after hearing what people were concerned about. But it's ok...I understand your V8 is the only way insecurities [/QUOTE]

Then why do you list an LT/RS as the car you own. Either way, insecurity has nothing to do with it. I use my car for more than just driving around looking cool. I like to race ,and it makes no sense trying to make a V-6 into a V-8 for a whole lot of money and still be slower than the V-8 guy that spent the same money on his car. If I wanted a car just to drive around in to site see, I might have bought a V-6. I have no problem with them at all. I just can't understand why someone would buy a V-6 and spend cobs of money trying to make it like a V-8. AS far as clearing up why V-6's don't sound like V-8's well, I have to disagree with many of the points you brought up. Bore size doesn't have as much to do with it as you seem to think.

[novice66]

My thoughts are simple, how much air, timing of the pulses of air and/which I guess could be speed of air, and diameter of pipe it expels from is what I think makes the unique sounds of the v8/v6.

[novice66]

If anybody knows how a musician uses his lips to blow air through a tuba and trumpet, that would be a good explanation as well. And the diameter of the two instruments as well.

It would not sound like a V8 anymore, but it would not sound like a V6 either. It would sound like something in between. Again it gets back to firing order.

A normal V6 would fire 120-120-120-120-120-120.
A normal V8 fires 90-90-90-90-90-90-90-90.

A V8 with two plug wires off would sound somewhat V-8 like because it would maintain the normal every 90 between the cylinders that are still firing.

In your example, the engine would actually sound different depending on which two cylinders where not firing.

You could have a "90-180-90-90-180-90," or a "90-180-90-180-90-90," or a "90-180-180-90-90-90," or a "90-270-90-90-90-90". Each one would have a little different sound, but neither would be exactly like a V8 or V6.

Guy, this whole thread is for in case the V8 disappeared due to the government restrictions coming in 2016. I have stated it multiple times that an existing v6 can not sound like an 8. If people would actually read the words infront of you, you would see I'm am talking about a whole new engine from the ground up. Yes I know its more than just bore size but like I stated before, bore size is at the core of what gives it sound, with out the right core size it doesn't matter what you do....the sound won't be there. And yes I have a V6 camaro...did it ever occur to you people have more than one vehicle? Guess not. Also why is it that you think that people with a v6 who modd it and spend "gobs of money" are trying to make it sound like a v8. How is that different from people with a v8 who spend gobs of money on the same thing. I guess I could say the same for you if ou bought or do have a supercharger.." gosh are trying to be a ZR1"? Ah doesn't matter corvette is still better and your wimpy SS will never compare. See I know that's not the case. People mod their cars because it is fun ad brings out the inerbeast in our V6 and V8 cars. But if your one of those narrow minded people who think if it's not a V8 then it's my worth having or spending money on..than I feel sorry for you and I'm sure other members do also. I hope you do not feel that way and just respect people, their cars, and what they do to them. We are all car lovers

I think you are failing horribly at seeing what everyone is telling you.

Maybe you can imitate the sound but you can't have the attitude of a v8. Sure you can make a v6 faster than a v8 but it'll never be that untamed beast of a v8. Who wants a turbo v6 when they can have a cammed v8 :P.

Wow man your a lost cause. Did you not read anything I just said? I never said anything about a turbo or cammed v8. I'm done. Didn't know I was talking to a child

[KMPrenger]

Back on track (if thats possible)...lets not turn this into another V8 vs V6 pissing match.

Gotten lots of answers for the original question...but nothing concrete. I'm going to go with its a combination of what has been listed above. (except for the 'magic' comment) lol

Hey there is concrete science supporting my claim!

[CamaroC-17]

ha! I love it

This will make your car sound like a v8

[Autobots]

Now what if instead of a v6 gm looked at doing a inline 6 dohc would that sound any diff? If the gen6 had a inline 6 dohc tt like the supra I would not be so sad. no more v8 just kinda sad lol
