Dodge Challenger Returns

What Elie said.

[Dr Mordrid]

Sigh....horsepower freaks

Horsepower is a function of torque and RPM; 1 hp = 550 lb/ft per second. Because of the way they're calculated bhp and torque are equal at one RPM: 5252, usually rounded to 5250. If you see a set of power curves where this isn't the case it's bogus.

Any given car, in any given gear, will accelerate at a rate that exactly matches its torque curve, allowing for increased air and rolling resistance as speeds climb. As long as the torque peaks at a high enough RPM to take advantage of the gearing all is well.

BHP is a great measure for the track because it peaks at a higher RPM than torque, but for normal driving torque is where it's at. Ask any farmer or trucker

Also; high bhp/cyl comes at high revs. Detroit avoids this, depending more on torque which is smart in street vehicles so as to reduce revs/mile which is an excellent indicator for engine wear. They try to minimize this even in their performance engines.

Ex: my Detroit vehicles (Chrysler & GM) have all lasted 200,000 miles or more while the Toyotas & Volvos were lucky to go past 100,000. The Volvos didn't.

That said Detroit engines, particularly the MOPAR & GM's, are capable of far more bhp/cyl than the stock values, which is why rodders can bolt on 100-200 bhp in 2-3 hours of back yard work. Taking the 6.1L to 600-800 bhp would be duck soup for most home rodders.

[Umfriend]

You had a Volvo that lasted not even 100kmiles???? Amazing? What did you do with it? Drive it through the defense minsitry in Iran or something?

[az]

Chrysler is fielding a new electronic variable displacement technology that can change a cylinders status in 40 milliseconds, mainly for saving fuel in low-demand situations. This is much more advanced than GM's horrid 4-6-8 tech of many years ago.

Besides; if someone opts for the 6.1L firebreather I doubt the mileage is a major consideration

Since when does penis status matter? I know as many girls with lead feet as I do guys...my daughter Sabrina chief among them. She steals the keys to her brothers street rod all the time

We have a saying here: No answer is an anwser, too

Why does the Mustang ned to be 5.0 Litres to produce 225HP at the time, my car produces a bit more than that with only 2.5 Litres with tons of torque.
Elie

The 5.0 produced over 300 ft-lbs of torque (at 3200 rpm)- and I doubt that what you condsider 'tons' of torque would hold a candle to that.
And for your info, that motor hasn't been used for over 10 years.
You are talking about a vehicle that cost just over $10,000 at the time and would outrun anything over 3 times the price.

Yeah and once in 5th gear the car dies, it could not beat me on the highway

I may have talked about various type of engines, old or new, but the facts are, Americans car makers have a two major problems

1-It seems regardless of what year we're in, they cannot get the horsepower out or a smaller displacement engine, they need to through as much gas at the Cylindars to produce the power, EXTREMELY inefficient.

2-American made vehicles suffer from poor handling, they are good for 0-60 but take it on the track without modifications or anything and you'll see what I mean.

I like Chrysler over GM and Ford because they are sharing technologies with Mercedes and are innovative to say the least but Ford and GM leave much to be desired.

Elie, I would normally agree with you. I'm a big fan of smaller higher revving engines, and I've never owned a domestic car. However, I think the new Corvette Z06 blows your above argument out of the water. If I was in the market for street legal track car, I think this would be the one to get. Sure, it needs 7 litres to get its 500HP, but what the hell...

Even Jeremy Clarkson loves it.

[Elie]

Hence my argument

but yes the new Vettes with the fixed head lights sure look nice and I think it still has the option to turn off 4 Cyls doesn't it?

Cheers,
Elie

[Byock]

I fail to see the argument. My Mustang Cobra has a 4.6 Litre V8 rated at 305HP. Yet, gets better gas mileage than my 2.0 Litre Mitsubishi Eclipse did stock.

I don't think 24 City 26 Highway is bad for a V8. Gas guzzler?

Drive a car with torque, and you will see what Doc is talking about the high reving small engines. They have no low end power, and if you get on them, they suck gas too.

hehehe those Crysler ads are cool

5th gear was a whooping .67 to one ratio, and with the factory 2.73 rear end ratio you where doing 1800 rpm at 120km/hour. Top speed was actualy achieved in 4th gear at almost redline and 148 mph.

1: - they have no problem getting horsepower from a smaller engine - American consumers drive with torque, not horsepower. There were plenty of smaller displacement
vehicles that made the same horsepower, but where useless on the streets, where your driving times where limited by stop lights.

2: have a look at at a road and track from 1987 or so - the Mustang was the second fastest vehicle through the slalom at the time - It was a matter of getting a driver that knew how to use tthe torque to their advantage. And a $5000 racing package on a $10,000 vehicle would still beat vehicles over twice the price. Ask Steve Saleen


@Guchi : LOL

[Fluff]

Audi A8 4.2 TDI quattro | £58,420
Maximum speed: 155mph | 0-62mph: 5.9 seconds
Test MPG: 29.1mpg | Power: 322bhp | Torque: 480lb ft

That's the engine you want for a green challenger. A nice 480 lb/ft twin turbo 4.2 litre V8 TDI from Audi. The sound wouldn't come close to that of the petrol engine.

Question: Where, other than on the track, do all you non-Germans actually use your fast cars' power legally?

[agallag]

Who said anything about "legally"?

When we need to pass those slower German cars
