370z powerband vs. 350z powerband

frost · 08-10-2009, 10:33 PM

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?!?

kdo2milger · 08-10-2009, 10:39 PM

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

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?

m4a1mustang · 08-10-2009, 10:44 PM

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?

Red370 · 08-10-2009, 10:59 PM

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.
