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.

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

m4a1mustang · 08-10-2009, 10:30 PM

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

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.

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?

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!

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.

Red370 · 08-10-2009, 10:37 PM

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

frost · 08-10-2009, 10:40 PM

^ almost there

m4a1mustang · 08-10-2009, 10:44 PM

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