HOT DAMN! I've been SONICTUNED!

[Mr. Mac]

If you could, please post your water and oil temps after some pulls or spirited driving. Also ambient temps at the time.

Here's a quick clip taken immediately coming out of ~20-minute spirited run through the twisties (Sport+ Mode, Manual Mode, ~90º ambient).

Damn that's good. Thanks!

No sweat. What are your thoughts on the diff temp? I know it's nowhere near the red, but 258ºF seems a lil high (highest I've ever seen so far actually), although I did just get done with 20m on high-rev manual paddle shifting out in the country twisties. Any concerns?

Honestly don't know what proper and safe temps for the diff should be.

Asked the robot and it provided sources for its answer:
• 170°F–220°F: Normal operating temperature for standard street driving.
• 220°F–250°F: Temperatures may climb into this range during aggressive street or occasional spirited driving.
• 250°F–275°F: This range can be normal during the break-in period of a new differential or after a gear change.
• 275°F+: In track conditions without an external cooler, temperatures can exceed 300°F. At this point, the fluid begins to degrade, which can lead to performance loss and component wear. [1, 2, 4]

Thanks for post! About to take delivery of '24 Nismo (great deals right now), and doing the AMS Heat Exchanger, Intakes, down pipes, and maybe exhaust, and for sure a tune. Two questions:
1. How much difference in power is full exhaust versus just down pipes?
2. Exactly which tune did you get and about how much cost for such?

Thank you.

Thanks. Assuming the robot is correct, this info at least makes me 'feel' better about seeing that 258ºF.

I'll check with tuner to get his thoughts on it as well.

Congrats on your NISMO!

Can't answer #1. I did the AMS LDPs and the full 3" exhaust kit at the same time (all the listed performance mods together actually) right before getting the tuning done. What I can tell you is that the factory exhaust is surprisingly tiny, like <2" I think, so I personally wouldn't do LDPs unless upgrading the exhaust along with it.

Regarding the tune; I went with Mark at SonicTuned and his full remote tune package. Pricing is on the webpage here, and sometimes he's running sale prices on it. https://www.sonictuned.com/product-page/VR30Z

Great picture of the road!

Thanks Mac! Great help. I'll go with exhaust and look into Sonic.

700NM ~ 516 LB-ft
pretty good trans to handle extra power, however other components would definitely need to be upgraded to actually make use of the added power.

Butt dyno feels much faster? Still get traction in the lower gears?

I guess the upgrade on the Nismo trans with the clutches and all would help as well hopefully.

Don't know how much more juice, if any, can be squeezed out of a dyno over the remote SonicTuned tune with the current mods done. All I know is that my Z now feels/performs like I want it to, so the actual hard numbers aren't really all that important to me, rather a mere curiosity. Also don't want to start flirting with reliability or having to beef up more components in order to properly mate with even more power, at least not at this point. Regarding lower gears' traction; haven't turned off traction control yet to see what's happening unassisted by it, but she will now consistently bark the tires in shifts 2-to-3 and 3-to-4 no problem at full throttle with traction control on before it auto-corrects. With the damn price of these Michelins I'll definitely be watching my right foot a lot more closely than before the tune.
