What HP & Torque Gains Expected With These Mods

Woketman

My car is a 2019 NISMO. I have installed the following mods so far: AAM CAI, and Extreme Online Store Axle-Back mufflers.

My question: if I purchase EcuTek hardware and etune (with logging) from Specialty Z (Sebastian), what horsepower and torque numbers can I expect??? And how reliable are those numbers?

Thanks.

Minimal, Intake and axle back do not give very much added power. Most would come from to tune. Guessing but +5-10whp.

If he base lines around 275. He might get to 300 with a good tune.

Well that is what I mean t. How much overall gain can I expect from both the CAI and mufflers and the tune. I know the CAI and exhaust won't do much. I am asking how much after that and the tune. Thanks.

That's what Rusty was answering. Typically speaking, in reviewing data, I've seen an average of about +10 whp just from the tune. Given the CAI you've added, you might eke out another +15 on top of that. Keep in mind that the 370z seems to respond most to the first performance mod. You would probably get +15 whp from a CAI or an exhaust, but you typically won't get +30 from both.

Rusty's answer of around 300 whp (I'm assuming you know the difference between Crank and Wheel horsepower) is going to be pretty spot on. The exact number will depend on what kind of dyno you use, what kind of correction factor (STD vs SAE), and the calibration of the dyno.

OK, thanks. That is about what I expected.

As per above, you're not going to see a big jump in HP - the factory has already picked all the low-hanging fruit. Off the top of my head, 20-30 extra HP seems to be what most people are reporting with similar mods to yours (and a tune). A lot will depend on who does the tuning and, as per JLarson, the dyno (and operator) will have an effect.

For many of the DDers on this site that have their Zs tuned, it's seems to be more about responsiveness than actual HP gains. The engine just feels peppier. Apparently there is some throttle lag built into the factory tuning.

i had my z with just a tomei catback tuned with ecutek by seb and i was doing 317 whp. the video was on their insta a while ago

just got z1 cai so im wondering if that will do anything too

haise

Speaking of experience, a bone stock 2019 Nismo will make approx 295 WHP on a Dynojet W/STD Correction. I tested a few 2019 Nismos with identical results including my own.

With an exhaust, you'll pickup ~10 whp and another ~5-8whp with a post MAF tube. The newer Nismos have pretty decent tunes out of the factory so they make decent power.

For older cars, we usually baseline sport/base/touring Zs at 270-280 whp, up to 300whp with bolt ons, and usually 320 to 330whp after the tune.

So the non-NISMO engines will have more power than the NISMO engines after both have bolt ons and tunes?
