that car was almost the sickest thing i've ever seen.

want.... want...:(

Its fairly decent... hehe...

Nova could take it though... fo sho!! :rolleyes:

Hehehe, ma, keep these vids coming. That was great, I would have just loved to have been driving that beast, hell, I would have loved to have just ridden in it.

I got to drive a 500hp GTS....I couln't imagin that!:eek:

Man, you're a butthole!!! :p

Fast as shit damn.

But can someone explain to me why Viper's V10 sounds like a 4 cylinder?

It was all in the exhaust and the exhaust porting, or so I'm told. I am just glad the new ones have the mean sound to them.

Butthole!? Me?! I just got lucky!

Oh, by the way it was black with silver racing stripes!

Is it possible to change the sound to make it tougher sounding?

I don't see why not.

How would that be done, the usual? Better muffler, bigger pipe, headers. If thats the case wouldn't it just sound like a louder 4 cylinder?

on the older vipers... before they put the exh out the back...

the side exh was separated... no H pipe... so you were only hearing 5 cyls...

that's a big part of it...

if you've got vids... put em in the video forum... that section is pretty dead... it could use new vids...

Even the ones with the pipes going out the back sound like 4 cylinders though. I have a video of a black w/silver stripes racing and it sounds just like this one. The video is called "Cream puff" Viper GTS.

My mechanic has a '95 Viper RT/10 with a $3000 exhaust system, and it sounds like a giant rotory motor. You can hear the fact that its a V10, but it has a sorta 'hummm' sound to it like a Rx-7.

Its veryy badass.

3000 jesus its that much to put a better exhaust on those cars?

I never understood why people spend that much money on exhaust... for that kind of money, you can buy yourself a welder, 5x the stainless steel you need to do the job, and learn a useful and marketable skill!

Anyways, the reason the Viper sounds the way it does is because of two big turbines in the exhaust flow. That really cuts down on noise. As a matter of fact, turbocharged engines run really low restriction exhaust, usually around 3" for a 2.0 4 cylinder, and a very low restriction muffler. This is why bolting a turbo muffler onto a NA car results in the fart can effect.

well its not like they're as common as say a Civic or a Camaro so the parts aren't in such high demand, so basically yes its expensive to get work done to them.

I cant imagine what it costs to have regular service done on them. Or if something broke. Sheeesh.

Just how they sound. And no, most exhausts for them run right about 1000 - 1300. That's how much my friend's Corsa system for his cost. Changes the sound but doesn't much make it sound like a V8 or anything. Number of cylinders has nothing to do with the loudness/deepness of the car. V8s are the ONLY engines that sound the way they do. Take a V12 Ferrari or something for instance. Very distinctive sound, but not deep, rumbling, or mean sounding at all. Firing order of the cylinders has a lot to do with it, but that's not really something you can go about changing:D

another interesting piece there is the size of the cylinder itself, as well as the stroke length and what not...

it's interesting to note that the viper has cylinders bigger than a 5.7 v8, but not that same sound... or a deeper one..

also, the viper motor was developed as an i5, and then they were mated together, which may have something to do with the sound...

a ferrari has smaller cylinders, and revs quite high, which is where that sound comes from...

V12's I've heard in some videos, sound pretty damn wicked. I'm asuming the Vipers in some of the videos I've seen have changed their exhaust and went with a different muffler. They're louder then any Viper I've been next to. I've had a brand new one fly right by me probably doing 80 or 90 on the highway and no sound came out of it at all. Real quiet. But in these videos they all have the waaaaahhhh sound that 4 cylinders have. I hate that sound. I would hate to have an expensive car sound like a cheap one.

Aha, tell it like it is Devil! Engines should make a nice smooth rumble... :D

Yea, I LOVE the sound the v12 Ferrari's make, it's wonderful. My favorite car in the world, the Ferrari 550 Maranella is a V12 and sounds BEAUTIFUL, it's the best sounding engine in the world in my opinion. But definately a lot different than a V8 for instance. Firing order of the cylinders plays a big part in it as well. Take the downright intimidating sound of the LT1 cars and put it next to the LS1 cars. The LS1s sound a lot more tame and toned down than the LT1s do. And a lot of that comes from the firing order.

The LS1's do sound toned down. They sort of sound weak actually, I guess to hide the fact it will whoop some ass?

I also notice a lot of the L98 V8's like in my GTA sound really different from the new ones. They got sort of that farting tough sound like motorcycles.

If I red the time slip correctly.. it says 10.11 right?? I know thats ultra quick and all.. but isn't it a bit slow for 1000hp??? Perhaps because of high(err... non-steep) rear gears? That acceleration from a roll was aaaaah....... super ultra amazing.


And damn.. I wonder how much green he had to part with for his turbo set up!

the hood on the viper alone costs 9grand to replace.

I believe the TT setup installed is like $50k, or something like that if I remember right.

Yeah shouldn't a 1000hp vehicle be in the 8-9 second range? What did they do just load it up with power?

the hood on the viper alone costs 9grand to replace.
Thank god for insurance.

So can someone please explain to me why this Viper's 1/4 time is so "slow" compared to the power figures?

friction, most vipers run street tires at the dragstrip, when they use slicks, watch out.

Why do you say that? I'm seen a bunch of Vipers at the track running on slicks, most fo the heavily modified ones anyways.

right, but those are the ones that are competing and are usually on speedvision and such. Maybe it is different where you live, but i know PIR and Firebird usually dont have many cars running slicks.

I wouldn't doubt it is using street tires.

Then again it could be using something like 9 inch slicks who knows. Like Viper 10 says, lots of people build up the car with a ton of power but don't realize there is more to it then that. Even putting on a slightly better gripping tire may not do the trick.

While that Viper is all very well and nice, I prefer a car with power ;)

Also, 3200lbs is just too heavy for me, sorry.

He may be running on those street/strip tires.

Yea, must be different, seen more than a couple of 'em running slicks. And not even all THAT fast, just running the slicks for better traction. Like any other car.

It seems a lot of people like putting out insane power in those cars but don't set it up right for a drag strip. Oh well there loss.

that must cost silly amounts of money. just can't comprehend turboing a pushrod engine. god they are so inefficeint.

Then you my friend, can not comprehend true power:D

HOLY CRAP is all I have to say :D

Oh i know that there is no replacement for displacement, but 450hp out of an 8 liter, thats not right. i know i can't compare it to something saying that is gets 56hp per liter and another car, like the s2000 gets 120 per liter. that would be like comparing apples and oranges, but that little of horsepower per liter, not total, is just crazy. i know it is the american way to have huge engines and cars that are drag strip and not track destined, with the exclusion of the z06, now thats an american car i am not ashamed to say i like.

First of all, you're forgetting about the issue of torque. I was reading a review on the new viper... One of the editor said that as long as you're obeying the speed laws in the United States, you can just leave it in second and cruise around like that all day.... From around town driving to the freeway... If my memory serves me correctly... The review also said that if you stomp it in any gear from a stand still, you will smoke the tires...

Secondly, not many people can even handle the Viper in stock form, much less a 8 liter v10 producing even close to 120hp per liter. That big v10 is a big factor in selling the Viper. Did you know that you can increase over 100 rwhp just by installing some bolt-ons in a Viper? From my understanding.. anything short of forced induction or opening up the heart of the s2k won't yield much power at all...

Imagine the cost of insurance on a 450hp car that costs like $80g's or whatever.... Now imagine the cost of insurance of a car that makes 640hp(Thats an 8 liter Viper that makes 80hp/liter, which is much less than 120hp/liter)... Stock... WHOOOOOOO... insurance would kick you in the ass 10,000 times a day.

Despite my lack of experience, I'd still say that the Z06 is MUCH more forgiving to drive than a Viper. Thus, allowing more people to drive it without getting out of control by just touching the throttle wrong...

Well its been proven, that a pushrod motor can be made to have the glorious 100hp per litre.

For instance, If dodge wanted to make their new motor have 100hp/litre it would have to be 830hp stock. 330hp from what it is now. So I think 500hp stock is just fine for now.

Chevy, would have to make the Z06 with 570hp. The Z06 already makes 70hp/litre not to shabby for a inefficient pushrod motor.

Just because they're bigger doesnt mean that they're Lazy per say... they have lots of room for improvement just like any stock motor does. So lets not call Pushrod motors a dumb word like inefficient, Cause even in their 'inefficient' form they still make more power stock per stock than a little OHC 4 cylinder. (Those who know me know thats not a bash against 4 bangers)

... My damn mother got to talking to me for 15 minutes while writing this post... I lost my train of thought... gahhh... oh well Im going to lunch so screw you peeps! haha.

Okay, first of all, very few engines get 120bhp/liter. A handleful of ITRs, the S2000... all of these engines do it by virtue of 11:1 or higher compression, extremely oversquare shortblock, and very high engine speeds. The engine timing is set up to take advantage of this setup, for high rpm power. This means the engine makes lots of hp for it's displacement, but is somewhat lacking on the bottom end. Now someone will chime in now and say "VTEC!", and it is a great help, but it still doesn't quite make up for the difference.

With a Viper, it's running 9.6:1 compression, a slightly oversquare bore, and low engine speeds. The engine is tuned for torque, and has more than you need at any engine speed. If you were to raise the compression to 11:1 like an ITR, and run the engine at 8000rpm, you'd see a lot more hp, but the tradeoff would be the torque.

So compare hp numbers is pretty meaningless unless you know how both engines are built. All said, a 500hp Viper engine will pull a 4.0 liter 500hp S2000 engine, on the drag strip.

Everytime I hear someone say inefficient they start going on about hp/liter. Must be a connection between those two.

Vipers are destined track cars btw. They just don't handle as well as a Vette thats all.

Well let me clue a few of you guys in, I have driven a Z06, my uncles to be precise. And my brother rented a Viper when we were in Las Vegas last September. Both are INCREDIBLE cars to drive, everytime you push the pedal down no matter what speed, you feel the back of your seat.

Now you guys want to say how inneficient that the Viper's engine is? well let me inform you that 500cid engine weighs less then your godly RB26DETT. So it may be inneficient as far as displacement/weight is concerned, but look at it from a technical standpoint. The Viper weighs in around 3100 pounds stock. Stripped it gets down to about 2800. So inneficient or not, it is a kick your ass car, just as worthy to be considered an exotic as some Lambos, Ferraris, Porscheas. And in many other countries the Viper is considered a exotic car.

BTW, when comparing the Viper to the Vette on the track is quite different, the Viper relies VERY VERY heavily on the drivers skill. Where as the Vette is so "smart" it makes you a much better driver so to speak. Track times, viper wins, on average though, the vette will win the race.

BTW, putting the viper into 6th gear at around 65mph stalls the engine.

i am not trying to say that the viper is crap, by all means it is the king of american muscle. It just doesn't do much for me, until the new one that is. i actually like the new one alot. I am just trying to say that it doesn't float my boat, but then again i haven't really given many american cars a chance. Anyway, i am not trying to piss people off or get on anyones bad list on my second day on this site. If you like it, thats cool, i am just more of a cheap speed man.

So... When exactly did Honda bump the S2000's Motor size to 4 litres? :confused:

Actually, the new ones pull more g's, brake quicker, accelerate faster than the z06.

Hahaha, it's the new prototype engine ;)

I'm just making a hp comparison, a 500hp engine with the hp/liter and torque/liter of the S2000 will lose against a 500hp engine with the hp/liter and torque/liter of the Viper.

Reason? The Viper engine is not inefficient, it's tuned for torque!

Actually, Vipers weigh in over 3200lbs stock, and I'm curious to know where you manage to strip 400lbs out of it... Remove the air conditioning? The rear seats? Oops, forgot for a minute that Vipers don't have any of these... ;)
