And for comparison, by 1977, the Electra was a trimmer, fitter beast.
My '77 had the 403 engine (from Olds division, as the 455 had been retired the year before).
It had 185hp and now weighed 3900lbs..
Which gave it a hp/weight ratio of about .047hp/lb..
Which is almost the same as the bigger boats that preceded it.
What hurt was increasing emission regulations, requiring lower compression, among other things. And that was making it increasingly difficult to squeeze hp out of the standard v8s with the technology they were using at the time.

Crack those 4bbls open and they would launch well enough to surprise some folks.

Yep, you could watch the gas gauge go down as the speedometer went up.

A 1969 Buick GS455 Stage 1 would give that '06 GT a good run for it.
I owned one.
In that trim, the 455 had around 360hp. And the car weighed 3700lbs., for a hp/weight ratio of .097 hp/lb..
Much fun.

In 1987, the fastest car ever to be produced domestically was the Buick Grand Nation GNX.
The 'X' meant....don't cross my path.
The 231cid v6 made 280hp and the car weighed 3400lbs....ratio of .082, which doesn't figure as the fastest.
But it was widely acknowledged as the fastest car made that year.
And they are collector's cars, still commanding rather steep prices used.

By 2013, the fastest Buick was the Verano. I can't seem to find accurate technical specs, but it can pull 6.1 secs 0-60. In contrast, the '87 GNX monster about 5.8 seconds.

All of which goes to show you, that the actual speed or quickness of a car is not held in the hp/weight ratios alone at all.
Many other things come into play. Current technology adds turbochargers, superchargers, and more accurate computer control over all operating parameters. The combination of transmission and real axle ratios (in the old days) or now, the transaxle ratios have a large part to play as well.

Today's cars are going faster with less engine and more technology.

Meow.

Quite correct. My gaff. Have edited my last post.
And I found the 6.1 second figure from another page on the same site you are linking to.

Thanks for the heads-up.

Oh, and Toothless, my '90 Ciera?
The 2.5l (150cid) Iron Duke for that year was rated at 110hp.
The car goes about 3000lbs.
Net ratio............. is .037hp/lb.
So it is surely not a screamer.
The stats site said top speed of 109mph (theoretical).
I like the 'theoretical' part.....LOL.
The original speedo went up to 85mph.
I swapped that out for one from a car with the v6 with the full gauge and tach package. That one stops at 115mph.

But, it's my baby. And I get about 23-24mpg in the summer driving back and forth to work and shopping.
And a trip to see my dad and brother 120 miles or so each way netted 29.3mpg at 70mph on the highway.
It drops down to around 18mpg in the winter with the extra drag running cold and the extra time to get up to normal operating temp.

Sounds like my CBR 1100.
Good for 300km on a tank of fuel taking it easy. 200km/h+ and you can see the fuel gauge fall steadily minute by minute.

Even worse for those who own a Bugatti Veyron, the fastest auto made, top speed of 253mph, the gas gauge will hit empty a lot faster any other auto, the only thing emptying faster, would be ones wallet...

If you can afford that car you can afford the fuel.

Me I'd be happy w/a newer Mustang V6, like this 2011 model. But I'd need about $22,000.00 to fix My car as a down payment, to buy and install some saddle colored Ford seats, install a brace, K&N air filter, and to buy this one below. I doubt I have enough income for a loan, if I did, I'd need less.

*shrug*
I've just got a 2004 Accent. Gets me from A to B and keeps me dry when it's raining & cool when it's hot. I only use it every few weeks (or months), rest of the time I just ride my bikes. A Grom for commuting, and my CBR 1100 for a bit of fun.
All of them combined cost less than a second hand Mustang, and only the CBR 1100 hurts when it needs a service (original Carby model, not fuel injected).

Scientists Say That Being Forgetful Is Actually A Sign You Are Unusually Intelligent

Having a fast or accurate memory recall is certainly something that comes in handy at school when you’re doing something like learning multiplication tables. It can also be useful in the workplace when you’re trying to remember someone’s name.

With that said, forgetting names or fun facts happens to the best of us. However, when it happens, it’s not unusual to feel slightly dumb for having had a brain lapse.

I loved my '86 GPZ 1000RX that, with a little head tinkering and a tuned 4into1 exhaust, produced 145hp at the back wheel and with me onboard had 1hp to pull every 2.5kg (5.5lb) along. It was good for flat 9sec standing quarter and I had it up to 265km/h (165mph) on Eastern Creek's main straight (and on 1 particular short piece of road on my way to work) on many occasions, fuel range depended on the wrist with the 21 litre tank doing 280-420km.

These days I'm happy enough with my old 1995 Ford Falcon wagon (and the 8'x5' trailer if needed) as it's meant to carry loads when required and just eats the distances here extremely well (they may even bury me in the old girl).

Cheers.

Why is it so hard to swat a fly?
You've probably pondered it after chasing a fly around your house and flailing your shoe with repeated, unsuccessful swats. How does it move so fast? Can it read my mind?

It was the question put to the BBC World Service CrowdScience team for our most recent episode addressing the apparent super powers of tiny animals. The answer is that, compared with you and me, flies essentially see the world in slow motion.

To illustrate this, have a look at a clock with a ticking hand. As a human, you see the clock ticking at a particular speed. But for a turtle it would appear to be ticking at twice that speed. For most fly species, each tick would drag by about four times more slowly. In effect, the speed of time differs depending on your species.

This happens because animals see the world around them like a continuous video. But in reality, they piece together images sent from the eyes to the brain in distinct flashes a set number of times per second. Humans average 60 flashes per second, turtles 15, and flies 250.

the furnace was just not getting any air

I've heard that the expensive HEPA filters are actually not a good idea to buy for exactly that reason. They restrict the air flow so much, they put a strain on the blower motor.

This furnace is 30yrs old, HEPA filters it doesn't have, it's clogged cause of Cat hair and dust.

Right, I'm just saying use of a HEPA-quality filter might not be a good idea.

The air filters are more like green scrubbing pads that are about 1/2" thick, minus the sponge.

Are they the reusable type that you wash?

I just use a cheap basic disposable filter, 16x25x1 size, and replace it once a month or so. There are HEPA style filters in that size, and they cost a lot more, plus the problem presented seems to be that they restrict air flow so much they might hurt the furnace.

they can be washed, though I'm not sure how, and they're not made of paper, no other filter will fit, outside of the type that stops grease, which was previously there.

What would be the reason to have a grease trapping filter in a furnace?

They were advertised as furnace air filters, they fit, plus they are washable.

If the filters are washable, doesn't that suggest they should have been washed?

We have a medical type HEPA filter unit running 24/7 (HoMedics AR 10A)

That's a nice portable one, and makes sense. My original point was that generic HEPA filters are marketed to people with big furnaces, but ordinary HVAC systems aren't designed to have that sort of restrictive filter.
