First I apologize for the vertically challenged dyno graph. I got tired of failing to correct the problem. But the reason I posted was because I was curious about what seems to be unusually low torque #'s.This is the first Z car I've owned. It's the first 6 cylinder I've ever owned for that matter. Coming from an all V8 history mostly F-bodies I felt the stock 350Z lacked the umph that should accompany such styling. So I did the typical bolt ons. CAI, plenum spacer, headers, cat deletes or test pipes as many call them, a cat back system( a little on the large side 3" but it's not dual) and a UTEC with custom tune. I've seen other Z's with essentially the same bolts ons that don't quite make the same HP but their torque is substantially higher. I was wondering if the low torque is due to the overkill exhaust or possibly the CAI causing the intake air to slow too much and is throwing the MAF off. The dyno pulls were done on a Dyna Pack. Any info or feed back would be appreciated folks. So please kindly help a wee old 05 Z 35th with a 5AT that torque is challenged and a member that can't seem to figure out how to insert a pic the right direction. :banghead:

I have an 06 5AT and those numbers look about right for the mods you have. You can look at my signature to see my mods. I make 267whp and 234wt on a 96 degree day with 30% humidity on a Dynojet.

Hey, I just noticed you are in Houston! What part of town are you in?

I'm located in the Webster area. I actually work at Clear Lake Infiniti but stay in Santa Fe. Peace out.

First welcome. Second you have the 35th Edition motor. Unlike pervious models that produced 287/274 OEM, your VQ35DE produces 300/260. So your results are on par. Kinda only benefit us older owners have. LOL Lastly I'm in the Spring/Woodlands area and will be taking my TTZ to SGP here shortly for tuning. Glad to see another Houston area member on TECH.

Please forgive me if I'm ignorant but I was under the impression that only the 6MT 35th and the 6MT Track got the REVUP engine. The tach on my Z redlines @ 6500ish and not the 7200 or 7500 the REVUP has. If my info is incorrect thank you for shining light on something new to me. Peace out. :irock: Oh and thanks for the welcome. :irock:

You don't own the REVUP (VQ35HR) motor. You have an "updated" VQ35DE. So yeah... You got more HP but lost some of the tq.

So are you implying that some Nissan ninjas have swapped my everyday run of the mill VQ35DE with some super duper prototype engine that has more ponies but scores a little low in the "seat of the pants dyno"? Utterly preposterous! LOL. But really I don't think that's correct. The "RevUp" and the VQ35HR are two different critters. Please see this sites wiki on VQ35HR. Though you stirred some curiosity so I tracked my window sticker down. On the sticker it says 287HP and 274TQ. But if what you say is correct please post some links so I may do some investigating. Peace :irock:

I just re-read your orignal post. Notice you said QUOTE

05 Z 35th with a 5AT.

ONe of two things here; 1) You don't own a 35th Edition. 2) The 5AT is effecting you preformance. Have you talked to SGP about this?

QUOTE

The commemorative model, one of six 350Z Coupe models offered in 2005 (along with three 2005 Nissan 350Z Roadster models), is highlighted by a higher performance version of the Z®’s standard 3.5-liter V6. The engine, which is available only with the 6-speed manual transmission, produces 300 horsepower versus the standard 287-horsepower V6.

Question at hand now is; How do you own a 35th Edition 5AT?

The All Wise wiki appears to be incorrect. Window sticker says in bold letters on top 2005 350Z 35th Anniversary. VIN JN1AZ34D95M607963. Feel free to call the local Nissan dealer if you like. In 05 the RevUp was introduced yes, but only on 6MT Track and 35th. On the 35th 5AT only the non oil burning VQ35DE a.ka. non RevUp was installed. Thankfully. I have the Brembo brakes, 18" Rays 35th wheels(which they turned around the following year and made them an option on base models), leather heated seats, all the amenities of the 35th less the RevUp and 6MT. So I don't what else to tell you on that but I will post a scan of the window sticker later. Peace. :irock: P.S. please see link. undefined QUOTE

Other key 35th Anniversary Z® equipment (standard on both 6-speed manual and 5-speed automatic equipped versions) includes unique 18-inch cast aluminum-alloy wheels, front and rear spoilers, Brembo® brakes and special Z® badging.
