370z powerband vs. 350z powerband
 

how does the 370z powerband compare to the 350z's? has anyone driven both to give a accurate comparison?

The difference is six. Sometimes seven but most of the time just six.

Actually i did see one time where it was five, but that is rare.

wtf?

The 350 is like, tooodllyyyy tam w0o0o0o, whereas the 370 is like, rabba rabba bam!

PS, I have both, so I know what I'm talking about.

That's what we all thought too at first but the dyno sheet showed it, plus johnny tran was like, "it is definitely five, I can feel it. but I know that this is very rare."

:rofl2: rotflmmfao "rabba rabba bam!"

now theres a highly technical term...take head all ye!!! "rabba rabba bam!" is that much faster than the 350z's :roflpuke2:

sorry bro had to do it...

hey here's the chart we ran when we got five

rabba rabba bam = 7

tooodllyyyy tam w0o0o0o = 6 (sometimes 5)

You guys must have gotten Wednesday motors.. mine's definately 5.

I have a Wednesday motor. They make 7 because that's the day the workers are fed. I guess five just happens on monday or tuesday when they are really really hungry.

This was done by a mystery tuner, but it can now be revealed that Thing 1 is the 350 and Thing 2 the 370,,,,

Thing 2 is is vastly superior indeed. Can't argue with specs.

the technology is just so superior. less parts eaten by the workers = more numbers on the charts.

now thats factual evidence YOU cant argue with!

I'm a little skeptical of the charts since they don't list tooodllyyyy tam w0o0o0o, OR rabba rabba bam rates.

Perhaps your question wasn't specific to which 350Z engine. The 350Z had 3 variations of motors: VQ35DE, VQ35DE REV UP, and VQ35HR. The DE had great torque down low with linear power delivery. The REV UP improved power on the high end, but sacrificed a bit of bottom end. The HR is the best of both worlds, and it is still a potent motor. The VQ37VHR is basically incorporates electronic intake valve control. There is a standard intake cam, and there is another "cam" above it that serves as the actuator to control intake valve duration and lift. So with this motor, the computer tries to optimize efficiency.

I had an '03 Z for 6 years, and I miss the bottom end grunt the 370Z sorta lacks. However, what the 370Z lacks on the bottom end it makes up past 3k RPM. It pulls hard to redline. The car definitely feels lighter on acceleration.

[EDIT] A couple of shops here have posted up dyno charts for comparison. It has been tooo long.

those are highly secret numbers the only way you can know them is to win iron chef america not once but seven times all in the same day.

Thing 1 seems to be running a bit rich judging by the spins curve, which is obviously why thing 2's numbers are superior!

the 370z has more torque than the 350z though. so your saying the 370z's torque is up higher?

why havent we hit page 2 yet?!?

ok....i have to hit 900 post before i pass out htis fine evening :rolleyes:

^ almost there

so since the vq35hr is the best of both worlds, you think its a better engine than the vq37vhr? it has more low end torque?

Are you trying to justify buying a 350Z instead of a 370Z?

Absolutely not. The VQ37 seems to respond very well to aspiration mods, I had almost 3k in my G35 and only jumped 20hp, no sir, no VQ35 will replace this bad mamma jamma!

no, just curious as to how the power band compare to both. so the 350z is a little more torquey than the 370z, but doesnt compare in raw power?

Why don't you just drive them both and figure out for yourself?

TQ numbers are 268 for the 50, 270 for the 70, so no difference really in TQ.

true, what makes most of the differance is how the torque comes in, in the higher rpm range or lower.

tq curve for the VQ37 is flat, pulls hard through all ranges.

is the vq35hr also flat?

look at the cute little babyyyyy

Epic thread. I approve.

Interesting, your motor actually replicates itself at about two and one quarter spins. Look at the Thing two line. At one point it seems to move backwards. But as we all know, it would be physically impossible for the Thing two line to go backwards.

Therefore, what is happening when your motor reaches two and one quarter spins a dimensional shift produces multiple motor inputs on the graph demonstrated by multiple pound and torks readings simultaneously.

That is a brilliant technical explanation.

In other words (Layman's terms for the mechanically challenged) , this is precisely when it prepares to Pounce.....;)

Not directed at anyone in general and just stating the obvious... You can't determine and compare power band by referencing peak figures like 306HP vs. 332HP and 268 lb-ft vs. 270 lb-ft. Those numbers mean nothing [to me].

The VQ35HR and VQ37VHR are very much alike, but the VHR has a bit more fancy computer gizmos to help it achieve a flatter torque band. So instead of peaky torque and power, you get something that's more consistent and linear throughout the range.

So what I mean by the VQ37VHR not being as responsive down low is probably because for daily driving the throttle response is quite conservative. It's a different story when you floor it. So how do you think I feel? :D

..or....the knock sensor malfunctioned right at that moment.
