370z powerband vs. 350z powerband

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

is the vq35hr also flat?

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?

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

I ran a 350z with aftermarket exhaust at the "track" and it was no contest. Pulled away with ease and waved bye bye in the rearview in the process. The 350 did look good though lol. Imho da 350 has 2 be well tuned 2 compete.

I'm still sticking with a dimensional shift.
