They measure the power to the wheels and then used X whp times .15. Then the X amount they got they added to the whp to get their measured horsepower. Damn man, only 193hp... that is really sad!

193.6hp x .15=29.04

193.6hp - 29.04= 164.56whp is absolutely garbage. Heck that's what I got when I dyno'ed my car and I'm sure my coils suck ***.



EDIT: I just looked at the dyno sheet and if you look at the top of the chart you see that the line is very squiggly at the top end. So that means it's the coils that's screwing it up right? Because in the dyno thread, it happened to some guy who had bad coils, im sure of that much So I guess they have to change the coils and the spark plugs to have the uptimum power. One last thing, what if they didn't disable the DSC completely?

I like that the 8 has a better track time than the s2000...

i watched the dvd and the 8 only made 164 whp.....and the drag driver was horrible every car had shitty times.....the s2000 ran a 15.5....even with shitty launches a s2000 can run mid 14's.......im still impressed by the 370z though it smoked every body around the track by alot.

shazy

But look at the dyno chart... doesn't the car look a bit sick? And +1 for rx8 getting better track time.

Wet track WTF? And yes I personally drove an S200 with an intake to a 14.0 flat in the 1/4. The 8's times are way off as well.

From watching the DVD that came with the magazine, the weather did not cooperate with them on the day of their tests. Hence they were not able to get track performance numbers on a few cars due to rain. And since they were on a deadline for the Sept. issue, they were stuck with a wet track.

So here's another car that got rained out.....

Rx8 lost by only .4 seconds....

DarthRX8

yup, even with added power from the 8's competitors it still holds its own on the track.

Remember the good old days when the 8 was new and opinions were more like this video:

Too bad they couldn't bring a 230hp RX-8 to really beat down the S2000 at the track...

Seriously though... RX-8 over S2000 by half a second on 1.5 min track? Kinda kills the validity of all the lap times in this test.

*sigh*

imagine if the rx8 really had the 232hp mazda advertised.

The rx8 has a 21% drivetrain loss. The guy at the garage I went to told me that the Dynojet's tech sent it out to all dynojets that rx8's have that much loss at the wheels. So let's say 180whp x 21%=217hp to the flywheel

Hehe, I like that the NEW FOR 2010 says Discontinued on the S2000. It kinda seems like they should have some good news there :P

Flashwing

Yeah there appears to be some ignition breakup toward the upper part of the RPM band. I'm sure that didn't help things.

blackenedwings

Sounds like that 8 they tested wasn't in very good shape to begin with, and its being compared to cars with drastically more power. A good turbocharger setup with the car will definitely bring the car beyond "V6 performance". Heck, even a GReddy setup properly tuned is going to be pretty damn fast with the 8s chassis. The car should have been factory turbocharged imo.

If all I wanted was an inexpensive and fast car, I'd go buy a Camaro SS and be done with it (if it weren't for the fact that it's the first model year and I don't trust Government Motors, I might). In the end, they can spout all the numbers they want, talk about power to weight ratio, track times, all of that crap, but in the end, to me, it comes down to this question...

Does your car have it? The 8 does.

CarAndDriver

Imagine if it had the 250HP like it was supposed to have from the start.

I say that Dsport did a pretty fair evaluation of the car at hand. Everyone who drives or has driven a stock Renesis would be lying if they said the car has suprisingly small amount of torque. And thats what you are feeling most of all in the seat of your pants. I never understand how owners get defensive about critisism of the car. No one said you made a mistake buying the car, no one said the car is terrible. The ratings systems are subjective based on what someone who is into Dsport would look for. Seat of the pants feel, a rough idea of HP (whats the point of quibbling over dyno numbers, we all know dyno numbers are not uniform, too many variables), aftermarket support, and track capabilities.
They did the homework, they went out and tested the cars, and reported their findings. Geezum people, relax, and just appreciate the article.

if the RX-8 is "anemic" and still beats a or equals cars around the track with twice as much HP then what is the point of those cars having the extra hp? and what are they doing with it?

Proxi

My thoughts exactly. Looking at the article, the lap times for all the RWD cars they reviewed are as follows:

Nissan 370Z = 1:28.496 (measured power/torque = 329/272)
Hyundai Genesis 3.8 = 1:31.302 (measured power/torque = 295/276)
Infiniti G37S Coupe = 1:32.246 (measured power/torque = 334/279)
Mazda RX8 = 1:32.634 (measured power/torque = 193/143)
Honda S2000 = 1:33.136 (measured power/torque = 246/172)
Hyundai Genesis 2.0T = 1:34.913 (measured power/torque = 219/263)

The RX8 ranked fourth on the best lap time beating out cars that have more power/torque. Plus the difference in the lap time isn't as big as expected from the cars it didn't beat.

Another thing I just noticed is that they were not using the R3 trim for the RX8. If they were using the S trim for the Infiniti or the Track trims for the Hyundai's (which are their top trims for those cars), why not the R3 for Mazda? I believe the RX8 R3 would've gotten a better lap time because of the better suspension.

If they'd used the track times shown for the ranking...all could be good even with these asshats. Just my opinion, but that just about how I would imagine the cars to work out against each other, perhaps with the exception of the S2000 was a bit too slow.

But the overall category rankings are just plain messed up. An example is "Overall Value" and "Performance" I mean wtf??

Considering the HP and $$ differences.. the results plainly don't sqaure up... I call bullshit or maybe these guys moonlight for Car and Driver. Both mags seem to take the actual results, throw them away and just give it to whatever car suits they're 'gotta have it' fantasy, ta hell with the results.

Personally, I don't give a rats *** what they pick, they get some points for including the RX-8, but then they simply blow smoke and ignore reality, perhaps because the think their readership looks for a different kind of car than the RX-8 represents. But in the end who knows...

...at $35,900 base

Infiniti G37S Coupe = 1:32.246 (measured power/torque = 334/279)



...at $27,185 base

Mazda RX8 = 1:32.634 (measured power/torque = 193/143)

besides their "measured" figures arent even actually measured figures. those arent the wheel figures those are the wheel figures with some added % to pretend what it gets at the flywheel. . we know from ACTUAL MEASURED ENGINES ON ENGINE DYNOS. that the renesis gets at least 215 at the Flywheel and that newer engines have been seen getting 240+ at the flywheel ACTUALLY MEASURED ON AN ENGINE DYNO.

If they got 164 on a dynojet its because the dynojet had pickup problems for the timing and not because thats what the rx-8 put to the ground. there clearly is no way a car of this weight could put basically the same time on the track as the G-37 with the 193 "measured" flywheel hp they are reporting

"cough" wet track "cough"

Do you take any of the top gear wet laps seriously?

Thought so.
