Turboed Viper with Nitrous

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

HOLY CRAP is all I have to say

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.
