Replace $$$$ with a 4 letter word beginning with 'c', ending with 'p' and has 'ra' in the middle!

Later!

The friggin forum script keeps editing the post no matter what I do!

This needs to be sorted, it is far too sensitive!

CODE wraps and LINKS, QUOTES etc. shouldn't be censored!

[sledge]

the link won't work

[Karma Supra]

Whats one of those then??

[Retribution]

Now that supra was a good sleeper

Nice 600bhp supra

You might will like this 1150bhp skyline lifting off the rollers



Or a 1000bhp Supra

[mud skipper]

theres a local tuner around here who has a supra pushing 950bhp, thats an engine if bolted into a surf would rip its self free

[darkdezigns]

and id just my skyline to back of my mind...........thanks lol

[nero279]

A guy down here had 2 supras, an 850BHP manual and an auto that pushed 1050BHP. Owns a company called Trac-art, formerly TorqueIC.

[Karma Supra]

There are loads of them.. I know some guys with one pushing about 1200 at the fly, (Mkiv) I also know a very very fast mkiii. They run 9 second and 8 secons quarters respectively!

A lot of these tuning company dyno run cars are dyno whores though, - set up for one thing only, maximum peak power at the expense of everything else... - and some are not built to last, just upped the boost for one dyno run to see what it gets type thing :P

Where or who has a 1200bhp supra in the UK?

[Karma Supra]

The Envy performance MkIV runs 1075hp at the fly. I beleive the XS power Mkiii is running nearer the 1200 mark. (like I said, 8 second quarter! - it hold the record for the fastest japanese drag car in europe) Both running 2JZ engines.


Its also worth remembering that British jap and american horsepower are actually different! Like US gallons vs UK gallons.

Power in hp is the same everywhere but there are lots of different correction factors, in the USA like the STD or SAE ones so the corrected power does change somewhat. The American STD is VERY generous and that's what you are quoted off most engine dynos in the US. The European standards are tighter as is the newer SAE standard.

Horsepower (hp) is the name of several non-metric units of power. The most occurring conversion of horsepower to watt goes 1 horsepower = 745.7 watts. In scientific discourse, the term "horsepower" is seen as inferior and is rarely used because of its various definitions and the already existent SI unit for power, the watt (W). However, use of the term "horsepower" persists as a legacy in many languages and industries, particularly in the automotive industry because of their continued advertising of maximum power output of internal-combustion engines in "horsepower" units of measurement.

There are two important factors to consider when evaluating the measurement of "horsepower":

The inconsistent definitions of the "horsepower" unit itself
The various standards used in measuring the value of "horsepower"

The power of an engine may be measured or estimated at several points in the transmission of the power from its generation to its application. A number of names are used for the power developed at various stages in this process, but none is a clear indicator of either the measurement system or definition used.

In general:

Nominal is derived from the size of the engine and the piston speed and is only accurate at a pressure of 7 lbf/in².[4]
Indicated or gross horsepower (theoretical capability of the engine)
minus frictional losses within the engine (bearing drag, rod and crankshaft windage losses, oil film drag, etc.), equals
Brake / net / crankshaft horsepower (power delivered directly to and measured at the engine's crankshaft)
minus frictional losses in the transmission (bearings, gears, oil drag, windage, etc.), equals
Shaft horsepower (power delivered to and measured at the output shaft of the transmission, when present in the system)
minus frictional losses in the universal joint/s, differential, wheel bearings, tire and chain, (if present), equals
Effective, True (thp) or commonly referred to as wheel horsepower (whp)
All the above assumes that no power inflation factors have been applied to any of the readings.

Nominal horsepower (nhp)
Nominal horsepower is an early Nineteenth Century rule of thumb used to estimate the power of steam engines.

nhp = 7 x area of piston x equivalent piston speed/33,000

For paddle ships the piston speed was estimated as 129.7 x (stroke)1/3.35

For the nominal horsepower to equal the actual power it would be necessary for the mean steam pressure in the cylinder during the stroke to be 7 lb/sq. in and for the piston speed to be of the order of 180-248 ft/s.[4]

Indicated horsepower (ihp)
Indicated horsepower is the theoretical power of a reciprocating engine if it is completely efficient in converting the energy contained in the expanding gases in the cylinders. It is calculated from the pressures developed in the cylinders, measured by a device called an engine indicator - hence indicated horsepower. It was the figure normally used for steam engines in the 19th century but is misleading because the mechanical efficiency of an engine means that the actual power output may only be 70% to 90% of the indicated horsepower.


SAE gross horsepower
Prior to 1972 most American automakers rated their engines in terms of SAE gross horsepower (defined under SAE standards J245 and J1995). Gross hp was measured using a blueprinted test engine running on a stand without accessories, mufflers, or emissions control devices. It therefore reflected a maximum, theoretical value, not the power of an installed engine in a street car. Gross horsepower figures were also subject to considerable adjustment by carmakers: the power ratings of mass-market engines were often exaggerated, while those for the highest-performance muscle car engines were frequently understated.[citation needed]


Brake horsepower (bhp)
Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump, and other auxiliary components. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system. The term "brake" refers to the original use of a band brake to measure torque during the test (which is multiplied by the engine RPM and a scaling constant to give horsepower).


hp (SAE)
In the United States the term "bhp" fell into disuse after the American Society of Automotive Engineers (SAE) recommended manufacturers use hp (SAE) to indicate the net power of the engine, given that particular car's complete engine installation. It measures engine power at the flywheel, not counting drivetrain losses.

Starting in 1971 automakers began to quote power in terms of SAE net horsepower (as defined by standard J1349). This reflected the rated power of the engine in as-installed trim, with all accessories and standard intake and exhaust systems. By 1972, US carmakers quoted power exclusively in SAE net hp. The change was meant to 'deflate' power ratings to assuage the auto insurance industry and environmental and safety lobbies, as well as to obfuscate the power losses caused by emissions-control equipment.

SAE net ratings, while more accurate than gross ratings, still represent the engine's power at the flywheel. Contrary to some reports, it does not measure power at the drive wheels.

Because SAE gross ratings were applied liberally, at best, there is no precise conversion from gross to net. Comparison of gross and net ratings for unchanged engines shows a variance of anywhere from 40 to 150 horsepower. The Chrysler 426 Hemi, for example, in 1971 carried a 425 hp gross rating (often considered to be understated) and a net rating of 375 hp.


SAE-certified horsepower
In 2005, the Society of Automotive Engineers introduced a new test procedure for engine horsepower and torque.[5] The procedure eliminates some of the areas of flexibility in power measurement, and requires an independent observer present when engines are measured. The test is voluntary, but engines completing it can be advertised as "SAE-certified".

Many manufacturers began switching to the new rating immediately, often with surprising results. The rated output of Cadillac's supercharged Northstar V8 jumped from 440 hp (328 kW) to 469 hp (350 kW) under the new tests, while the rating for Toyota's Camry 3.0 L 1MZ-FE V6 fell from 210 hp (157 kW) to 190 hp (142 kW). The first engine certified under the new program was the 7.0 L LS7 used in the 2006 Chevrolet Corvette Z06. Certified power rose slightly from 500 hp (373 kW) to 505 hp (377 kW).


hp (DIN)
DIN horsepower is the power measured according to the German standard DIN 70020 and like the SAE net figure is measured at the flywheel. However, DIN "horsepower" is often expressed in metric (Pferdestärke) rather than mechanical horsepower.


hp (ECE)
ECE R24 is another standard for measuring net horsepower. It is quite similar to the DIN 70020 standard, but the requirement for connecting an engine's fan during testing varies. ECE is seen as slightly more liberal than DIN, and ECE figures tend to be slightly higher than DIN. John Deere is one strong adherent to ECE testing.


9768-EC
9768-EC is a European Union Standard. Generally very similar to ISO-14396.
IN SHORT 100BHP IS 100BHP HERE OR THERE

Very good. A copy/paste from wikipedia.

I lot of text that backs up what I said. More concisely summed up in;

"The American STD is VERY generous and that's what you are quoted off most engine dynos in the US. The European standards are tighter as is the newer SAE standard."

So without getting into semantics, speaking to the simpleton at the pub "British jap and American horsepower are actually different!"

[Retribution]

I still prefure jap vehicles higher standard than over here and me love toyota

Also a lot of people buy uk spec supras and put in the 2JZ engines that actually make the car cheaper to insure rather than buy a import then insure it, they been doing that on mr2's for ages and i'm sure others in clubs have too.
Anyway check this site out.

read the cut and paste they are the same

a uk gallon is bigger than a US gallon
a UK 100bhp is not bigger smaller less powerful than a US 100bhp

However it can be measured in differant ways or at differant points on a vechile but 100 is 100 speaking to the man in the pub
