2007 HR,, 327bhp
hi guys.
i've been checking the new Hr egnine and on all the article i read it was 306 hp, but today i was in the nissan dealer. and i was shocked to find the specs as 327hp .
i am in dubai . so the new Z with the HR is considered 2008 model. 2007 was with the normal old engine. and the 2007 is 310 hp.
i didnt believe the guy and i spoke to teh sales manager and he confirmed that it is 327hp and he gave me the spes paper which was sent from Japan. i will upload it later after i scan it.
any thoughts ???

Quoted from Wikipedia:
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.

I know Wikipedia is not a credible source, but for the most part it's a great resource for general knowledge. I thought the entries on hp were a good comparison that explained the difference pretty well.

I like saying 315 rather than an odd number of 306 lol, and we all honestly know the 07 is definetly faster than the 300hp rev up.... stock for stock an 07 will definetly win, its definetly not 6hp doing it lol, but yes i know the power curve is much more linear.

If i remember correctly, pre-07 was not SAE hp, therefor they may be a bit inflated. the 07 is SAE, so it is test with SAE people there with all the crap(alternator, pumps) on it, so SAE is lower. I read somewhere that if the the HR was rated non-SAE it would be around 315-320. If someone know more, or if i am horrible mistaken, please chime in.

The Europeans calculate hp differently than us (Veyron's tout 1001hp when current SAE only gives them 9xx, right?), why couldn't the Dubai rating be based on a different set of calculations?

Tool. Shed.
If you're running stock tires and a 287(yeah, the 287, screw the 300) car is running good tires and good driver, you'd probably lose.

I was waiting for that. Lol!! :-)
Hey Tool (or is that mister Shed), check out these time slips... The HR averages about the same as the DE in the 1/4 mile-
