since joining gold i have

met some fantastic folks who i hope i will know for many years

been karting, on a factory tour gone to billing ,lotherton hall, stoke, Gaydon, Cotswolds, Derby, Donnington, Brooklands, cheshire oaks

and met

zee, loz, harty, duncan, gus, matt, mat, :winky: lyn imi, maz, mrbvg, johnny, paul, jac, rhains, figits, ifraz, sanj, kavey, steve wm, randyraindeer, steve admin, bazza, mrs bazza, PJ, mrs pj, sammy, mr sammy, sammys nsx, grim, dave sporty+ family, javadude, fargo ,rod, mitch....the list could go on into hundreds

now i would have paid to meet each of these folks at they are all warm harted and generous

each member has helped make this club into a real community

the question is what would make you not part with £25 cos if you dont what will you miss out on next year and who will you never meet

so i saved some cash on servicing and parts if i didnt have the lex would i have spent the money ? i dont kno

i dont care every time i log on i see friends

£25 its nothing

Lozzy, are you gonna let girly Mat talk about you like this?

girly.... me

is that cause i wear moisturiser :winky:

if i get some new silicone hoses in the future it would be nice to know how to change the fluids in the car

coolant.

power steering .

gearbox oil

oil

infact every fluid would be good

appart from washer fluid...

well taking little loz climbing on wed, with daniel who i already teach, lyn of course and loz....

guess which one wants to be a spectator is it

A: me climbing since i was 10

B: little loz, daniel who are both 10 and full of beans

C: lyn who goes climbing with me

D: big bad rufty tufty loz with the noz bling bling and all that .....

the choice is yours .....

and yes loz your car goes faster than mine :winky:

but not as fast as a KA

:zee:

perhaps those suggesting others should really post where they think we should meet

i posted llandudno

we could cruise the seafront go up the cable car go skiing have a packed lunch whilst sitting in our car ... sorry drifted off there must be my impending birthday getting old you kno

southport???

wales is cool for us

too

would love some nothen folks to turn up

especially some of our manchester bretheren :zee:

I forgot........

you chiming device finishing point

we were there then chris left and it was just me ....

and a load of lads who said my car was cool , but it is dead underpowered coz they said so on top gear

clarkson rules man

wht didnt you buy a scoobie man or an evo .....?

they had an oil burning escort .....

well thanks to all those who bothered to turn up

imi ill pm you my phone number

peace out ........

this week i have mostly been listening to the levellers

now if you go gold you could have got a discount on them....

you wont be dissapointed tho

happy birthday sir

have a bloomin good un

get any nice pressies? :winky:

nope it will stand i think about 10 bhp less than you have at any time

happy birthday pimp daddy

How Horsepower Works

Definition

The term horsepower was invented by the engineer James Watt. Watt lived from 1736 to 1819 and is most famous for his work on improving the performance of steam engines. We are also reminded of him every day when we talk about 60-watt light bulbs.

The story goes that Watt was working with ponies lifting coal at a coal mine, and he wanted a way to talk about the power available from one of these animals. He found that, on average, a mine pony could do 22,000 foot-pounds of work in a minute. He then increased that number by 50 percent and pegged the measurement of horsepower at 33,000 foot-pounds of work in one minute. It is that arbitrary unit of measure that has made its way down through the centuries and now appears on your car, your lawn mower, your chain saw and even in some cases your vacuum cleaner!

Measuring Horsepower

If you want to know the horsepower of an engine, you hook the engine up to a dynamometer. A dynamometer places a load on the engine and measures the amount of power that the engine can produce against the load.

Torque

Imagine that you have a big socket wrench with a 2-foot-long handle on it, and you apply 50 pounds of force to that 2-foot handle. What you are doing is applying a torque, or turning force, of 100 pound-feet (50 pounds to a 2-foot-long handle) to the bolt. You could get the same 100 pound-feet of torque by applying 1 pound of force to the end of a 100-foot handle or 100 pounds of force to a 1-foot handle.

Similarly, if you attach a shaft to an engine, the engine can apply torque to the shaft. A dynamometer measures this torque. You can easily convert torque to horsepower by multiplying torque by rpm/5,252.

You can get an idea of how a dynamometer works in the following way: Imagine that you turn on a car engine, put it in neutral and floor it. The engine would run so fast it would explode. That's no good, so on a dynamometer you apply a load to the floored engine and measure the load the engine can handle at different engine speeds. You might hook an engine to a dynamometer, floor it and use the dynamometer to apply enough of a load to the engine to keep it at, say, 7,000 rpm. You record how much load the engine can handle. Then you apply additional load to knock the engine speed down to 6,500 rpm and record the load there. Then you apply additional load to get it down to 6,000 rpm, and so on. You can do the same thing starting down at 500 or 1,000 rpm and working your way up. What dynamometers actually measure is torque (in pound-feet), and to convert torque to horsepower you simply multiply torque by rpm/5,252.

If you plot the horsepower versus the rpm values for the engine, what you end up with is a horsepower curve for the engine. A typical horsepower curve for a high-performance engine might look like this (this happens to be the curve for the 300-horsepower engine in the Mitsubishi 3000 bi-turbo):

What a graph like this points out is that any engine has a peak horsepower -- an rpm value at which the power available from the engine is at its maximum. An engine also has a peak torque at a specific rpm. You will often see this expressed in a brochure or a review in a magazine as "320 HP @ 6500 rpm, 290 lb-ft torque @ 5000 rpm" (the figures for the 1999 Shelby Series 1). When people say an engine has "lots of low-end torque," what they mean is that the peak torque occurs at a fairly low rpm value, like 2,000 or 3,000 rpm.

Another thing you can see from a car's horsepower curve is the place where the engine has maximum power. When you are trying to accelerate quickly, you want to try to keep the engine close to its maximum horsepower point on the curve. That is why you often downshift to accelerate -- by downshifting, you increase engine rpm, which typically moves you closer to the peak horsepower point on the curve. If you want to "launch" your car from a traffic light, you would typically rev the engine to get the engine right at its peak horsepower rpm and then release the clutch to dump maximum power to the tires.

Horsepower in High-Performance Cars

A car is considered to be "high performance" if it has a lot of power relative to the weight of the car. This makes sense -- the more weight you have, the more power it takes to accelerate it. For a given amount of power you want to minimize the weight in order to maximize the acceleration.

The following table shows you the horsepower and weight for several high-performance cars (and one low-performance car for comparison). In the chart you can see the peak horsepower, the weight of the car, the power-to-weight ratio (horsepower divided by the weight), the number of seconds the car takes to accelerate from zero to 60 mph, and the price.

Horsepower Weight (lbs) Power:Weight 0-60 mph (seconds) Price

Dodge Viper 450 3,320 0.136 4.1 $66,000

Ferrari 355 F1 375 2,975 0.126 4.6 $134,000

Shelby Series 1 320 2,650 0.121 4.4 $108,000

Lotus Esprit V8 350 3,045 0.115 4.4 $83,000

Chevrolet Corvette 345 3,245 0.106 4.8 $42,000

Porsche Carrera 300 2,900 0.103 5.0 $70,000

Mitsubishi 3000GT bi-turbo 320 3,740 0.086 5.8 $45,000

Ford Escort 110 2,470 0.045 10.9 $12,000

You can see a very definite correlation between the power-to-weight ratio and the 0-to-60 time -- in most cases, a higher ratio indicates a quicker car. Interestingly, there is less of a correlation between speed and price. The Viper actually looks like a pretty good value on this particular table!

If you want a fast car, you want a good power-to-weight ratio. You want lots of power and minimal weight. So the first place to start is by cleaning out your trunk!

took me ages to type that

hey guys.. click here for fun!

Mr Misery guts!

that wasnt fun .....

:shutit:

whats this.. fill the forums up with complete crap? cos i never would oh no 100% top quality info from me oh yes sireeeeeee

aye cap'n :winky:

she'll never look at this one i bet ......

i wonder who will

Yes semen is good for the skin, the rumour is the Body Shop once considered wether it could be used cosmetically!,..

What was the marketing campaign?

How were they going to dispense it ....?

How would they collect it ?

Oh the list goes on, and the giggles get bigger :D

To the mods.....

DO YOU KNOW WHO IS MASQUERADING AS SPORTIES DAUGHTER??

AND YOU'RE ALL PERVS FOR LOOKING :D :mat:

yep .....

but dont expect tea and buns round at ours

loz and lyn are opening a butty van

i think i've found the ideal butty van

Rachael....... Raquel...... Rebecca...... Rapunzel......... Rumplestiltskin???????

i kno - its the car :D

yes

may i welcome you to the club and point you towards the search facility

oh hang on ... erm

snooper s6 neo sorry chris

Mrs Sportie??????

..................family of pervs :D :D :D :D :D :D
