with all these auto manufacturers making a crap load of money, for every model they sell as for the different rims and tires sizes available.....what is the actual "horsepower to the wheels" is what they should at this point post in thier brochures and advertisements, etc..., along with its "peak" performance. This will give a better piece of mind for the consumer to compare the numbers within and ensure they are getting what they pay for. Even "horsepower to the wheels" we can barely use on a daily basis. Everywhere we go do we always "drop the pedal to the metal"? Don't get me wrong here boys, I too love the power "on demand" but like Milla said, just be straight up with the numbers and cut the BullS#!T, that goes for all other 4 bangers, to the V6s' , V8s', V10s', V12s', V16s', V24's, whatever comes our way into the future.

The VQ35DE is capable of producing 300HP, and it has shorter intake runners to improve air flow, it also supposedly has variable valve timing on both sides this time (intake/exhaust).
The only thing missing is direct injection (NeoDI) which is already available in Japan in the VQ25DD and VQ30DD, but these engines do not have any sort of VTC or NeoVVL like the 35DE.
I have heard that NISMO is testing a VQ35VE/VQ35DD with NeoDI. It would be interesting to see how much power the VQ can put out with the addition of NeoDI. Nissan has a normally aspirated 4-cylinder motor called the SR16VE N1 in Japan that puts out 125 HP per liter, but it uses NeoVVL also.

All the VQ engine cars were reported under the old SAE standard.

At the bottom of the page it says:
"* All horsepower ratings are per SAE J1349 AUG2004"
Same thing for the FX45, M45, Q45, and QX56.

Sometimes you can't put 100 % confidence on the accuracies of the little details of Nissan/Infiniti's published info, such as sales figures if the M35/45 still listed today as last year's M45 only, as in this case where this little detail on the specs. of certain models conflicting their official press release. 
Sometimes the info released by manufacturers do have mistakes where you can spot from time to time . . .

Funny thing is that ALL of the SUVs I have raced against have lost, even ones with more powerful V8s (even when I tell them to run only a 1/4 tank of gas next time). Following all of my suggestions they still lose. I know some of these cars have more weight, but some of these cars like an Acura MDX losing to a little old slightly modified RX300? This happened just last week.

And...why worry about an 0.2 second difference? Who cares? That, IMO, is trivial.

Read again, 2005 RX330 in Consumer Reports showed 17.0, 99 RX300 (not RX330) showed 16.8 according to Lexus
This is a big difference for two cars with two different engines, with the RX330 being more powerful.

The MDX is all time AWD and AWD cars soak up a lot of HP. If yours is AWD you have a pretty quick RX.
I have an AWD. Maybe it was the heat shield I just put on my intake last Saturday...I can already feel the power. It also helps to drive it hard before going to the track. This takes about 15 minutes solid before I feel the boost.
Tomorrow, I am going to put a larger CAI with wider PVC piping to suck in even more air from below.
If am beating cars like MDXs, Muranos, ML350s, Grand Cherokees, I must be way above 220 hp stock.
Too bad I don't know a place to dyno down here.
