Damn man your getting some great numbers off the dyno! I am going to have to follow your mod list in hopes I can hit 350 WHP! :tup:

semtex 05-25-2009 11:45 AM

Yeah I'm hoping I can hit 350 after I get a tune. I think it'll be close, but I suspect I may come up a little short of 350.

Shoot man even if you hit 240WHP with a tune would be sweet. I would expect it to be more than 10 WHP increase but wouldnt be surprised if you were right tho.

Ohhhh I hope you do hit 350, lol. Ever plan on going down the 1/4?

I'd like to see how quick the car has become...

240whp? You meant 340, right?

At this point I'm just waiting to do a dyno tune / ECU reflash at Forged Performance. They use UpRev, so I'm waiting for UpRev to complete their 370Z development.

Hardly, why would I hate it? I think its a solid car. I just don't see it as being worth the extra cash.

gatorfast 06-19-2009 12:12 PM

Was just joking around since I saw all your posts in the nismo thread playing devils advocate to the nismo.

Gotcha lol. Some people (read: people who intend to purchase it) just cant stomach the fact that not everyone is going to see it as being worth it, and this offends them.

semtex 06-19-2009 12:32 PM

The only thing that might make it worth it, IMHO, is the added stiffness from the special weld process. That is not something those of us with the non-Nismo models can add.

Ahh, but, only one problem - according to the review, they didn't do any welding on this chassis - just mucked with the suspension.

2009 Nissan Nismo 370Z First Drive and Video on Inside Line

Quote:

Though the body of the 2007 Nissan Nismo 350Z was seam-welded like that of a racing car, the 370's only additional structural enhancement is a different front strut-tower brace. "This car's stock body is stiff enough to meet the additional demands placed on it by the Nismo hardware," says Nathaniel Mason, senior manager of product planning in Nissan's Specialty Vehicles division.

semtex 06-19-2009 12:43 PM

Hmm...interesting. I could've sworn they previously said it was seam-welded on the assembly line. If it isn't, then yeah I agree. Not worth it.

semtex 06-19-2009 12:46 PM

Dude, they did a ninja edit on their article! I wasn't imagining things. This is the article where I read about the seam welds.

2009 Nissan Nismo 370Z - 2009 New York Auto Show

And this is a quote from their original article:
Quote:

Underneath its showy aero bits, the 2009 Nismo 370Z is no less hard-core than the 350Z Nismo. Autech still takes the standard Z-car chassis off the assembly line and welds the seams of the unit body by hand — a labor-intensive process that increases structural rigidity beyond that of a normal, spot-welded unibody. Mass dampers are then fitted between the unibody's left and right frame members to control the extra vibration inherent in a seam-welded chassis.
Which they now edited to read:
Quote:

Underneath its showy aero bits, the 2009 Nismo 370Z is a pretty hard-core machine. It's not seam-welded like the 350Z Nismo, but its chassis has been stiffened to the point that mass dampers have been fitted to control vibration.
Check out this sticky. The full original article is quoted in the sticky. http://www.the370z.com/nissan-370z-p...4-07-09-a.html

MightyBobo 06-19-2009 01:15 PM

Thats what they get for simply assuming. Then they probably found out the truth lol.

Proof that magazine reviews are full o' crap, eh?

WARNING - Nissan 370Z Wheel Locks ARE WRONG

WARNING: The wheel locks being sold by Nissan for the 370Z are NOT the correct wheel locks. I had these very same locks on my 370Z Rays and after one month of driving with them the locks began to show signs of stress fractures around the locking pattern. One wheel lock completely sheared of from the pattern to a 1/4 inch down the lock shaft itself.

I took it over to the Nissan dealer and they indicated the locks that are required are shank-style and the ones being sold by Nissan as the wheel locks for a 370Z are not shanks and they need to be......and they should NOT have the beveled tips but rather instead be straight shaft shanks.

In fact they showed me that these "Nissan 370Z wheel locks" don't even screw on far enough to make contact with the wheel to create locking pressure on the wheel. These wheel locks are they said in plain words the wrong wheel locks to use on the 19" Sport Rays application.

They told me that I have been driving around for a month in essence with just 4 lug nut on and that any cornering in the past month I was doing was putting severe stress on the "Nissan 370Z wheel locks" which was what was causing the wheel locks to fracture.

They indicated the correct wheel lock for the 370Z Rays is the McGard
#21153 wheel locks
as these are the correct shank length and shape in that they are straight shafts.

Fortunately no damage was done to the Rays while driving for the past month with the wrong wheel locks being sold by Nissan .

This isn't quite correct. I think there's some confusion on the part of your dealer. I recommend you review this thread, where this topic has been thoroughly covered: http://www.the370z.com/wheels-tires/...d-lug-nut.html

But I'll give you the Cliff Notes real quick. When the 370Z was first released, they did not have wheel locks. Dealers started just throwing on the standard wheel locks that fit all Nissans, not realizing that the Z's wheels were different. This picture here shows one of the lug nuts from a 19" Rays Sport wheel on the left, and one of the 'standard' Nissan locks that the dealers were putting on:

http://www.the370z.com/members/chris...ocking-nut.jpg

This was a colossal fail on the part of the dealers, and these standard locks started fracturing, as shown on the far right of the above pic.

Since then, they have finally gotten with the program and now have locks that are correct for our wheels. This is what they look like:

http://img294.imageshack.us/img294/9338/img0236.jpg

These are the ones you want. Notice that they're exactly the same dimensions as the stock lug nuts. So your blanket statement that "The wheel locks being sold by Nissan for the 370Z are NOT the correct wheel locks" isn't quite accurate. It depends on which locks your dealership is selling. If a dealership is selling the 'standard' Nissan locks for the 370Z, then yes, those are the wrong ones and they need to come off asap. But if they're selling the ones pictured above, those absolutely are the correct ones and there's nothing wrong with them.

The McGard 21153s I put on my car are also compatible, but understand that I put them on my car as an interim measure. In other words, I ordered them before Nissan caught up and released the correct locks. Now that the correct ones are out, there's really no reason to go with the 21153s. Btw, just as a side note, the Nissan locks are also McGards (i.e., McGard makes them). In fact, I have since swapped out the 21153s for the 'correct' locks from Nissan.

Hope that clears things up. :tiphat:

A sad thing happened this morning. I was on my way to gym at 5am and, upon exiting off of the highway, discovered a dead body laying in the middle of the exit ramp. I'm glad the 370Z handles so well, because I had to swerve hard to avoid hitting him. And with how low the Z is, the body would have caught the front and dragged. Anyway, it was a gruesome scene. I pulled over, and the poor guy's legs were crushed, as was his head. There were skull fragments and bits of brain laying all over the place. Some of those fragments must've been on the main highway, because as cars drove past, I could hear the sound of them cracking. I had to go home afterwards, I just couldn't work out at the gym. I still don't feel quite right. I've seen worse on the internet, but something about seeing this up close and personal is just different. Thumbnail below. I took pics with my BlackBerry in case the police need them for evidence (it was starting to rain just as the cops arrived). Don't open it if you're squeamish. It's really blurry and not all that graphic as a result, but still. May the poor guy rest in peace.

dainedazz 09-16-2009 08:25 AM

^^ wow omg. that is sad. i wonder whats the story behind that.

M.Bonanni 09-16-2009 11:23 AM

oh damn, not a pleasant way to start your day for sure.

holy ****.

i feel funny just reading that.

and i wouldn't even want to do anything if i saw that in person. i probably would've puked...

ECU tune results are in
 
Here are the results from my ECU tune using UpRev. Sharif at Forged Performance did my tune.

http://i618.photobucket.com/albums/t...Tune102809.jpg

With A/F ratios:
http://i618.photobucket.com/albums/t...e102809_AF.jpg

Baseline: 311.9. Final number: 318.1 Net gain: 6.2whp

Separate discussion thread here -> http://www.the370z.com/tuning/10654-...semtexs-z.html

theDreamer 10-28-2009 06:04 PM

Not overly great, but from your earlier dynos the car seemed to run pretty damn well to begin with.

6MT 10-29-2009 04:17 PM

Semtex, with regards to your "dream" factory tune mentioned earlier... When you installed your intakes, you probably took the battery leads off. And the ECU did its "re-learn". Was your base-line dyno result (the one that compares to this last one), the one that you considered the "factory" tune?

There is a good reason why I'm asking this. I'm not trying to put your results down, but my dyno was similar to yours. I had results in the 310whp range with HFC's, CBE, and CAI (no ECU tune). I've never posted my results here because of the "back-lash effect". I'm sure you know what I mean.

Anyways, I'm just trying to see if my car also was "gifted" with the dream factory tune and thus, the bigger whp numbers.

semtex 10-29-2009 04:22 PM

Well, the 311.9 figure you see above was pre-tune. So it was the pre-tune baseline, aka the "factory tune." Glad to hear you're making good numbers too. What kind of dyno did you use, if you don't mind me asking?

6MT 10-29-2009 04:28 PM

A Mustang dyno. Done at HP Solutions here in Edmonton back in late July. Well, I still won't post my official results here, but I do feel much better seeing your numbers being almost the same as mine.

Edit: I did not do a baseline pull since my bolt-ons were installed at the dealership when they did the PDI. So I had no numbers for comparason purposes.

semtex 10-29-2009 04:33 PM

Yeah, based on the similarity in our mods and dyno numbers (Dyno Dynamics and Mustang dynos read very close to each other), I'd say you probably have one of the "dream factory tunes," as you put it. lol I wouldn't be shy about posting your results. 310whp on a Mustang is really good. In fact, I think that's what RCZ is sitting at right now. So we actually have consistency between three cars!

RCZ 10-31-2009 03:40 PM

Yeah, it seems that full bolt on's will get you around 310whp on this car... I think with a tune we should all be around the 320whp range (Mustang Dyno numbers)

I'll get mine tuned the moment you guys figure out whats up with those coldstart issues.

theDreamer 01-17-2010 01:26 PM

Semtex and others, any news on UpRev and any updates or is what they have produced the final revision?

semtex 01-17-2010 02:38 PM

I haven't heard anything. Been wondering myself, actually.

theDreamer 01-17-2010 02:39 PM

Well if you find out, let us all know.

motoextreme 01-17-2010 05:11 PM

Wow, that was definitely a surprise...we need to cheer up this thread a little, that's one horrible way of starting out your day.

I've seen more people on the side of the road then I would like to admit, one of the reasons I really don't ride crotch rockets anymore. Ortega Hwy took its fair share of lives, I'm sticking with 4 wheels from now on.

ZLUJ 01-19-2010 04:57 AM

This is a great thread.

theDreamer 02-04-2010 07:22 PM

Got an email from Uprev about VVEL:
Quote:

VVEL control isn't something people are going to want to jump into. If you break anything in the VVEL system, expect to spend $10k+ with Nissan as they are the single and only source for those parts. They only sell VVEL parts as a pair of complete head assemblies. So if anything breaks your minimum out of pocket expense is $10k+
Looks like they view VVEL as a non-seller and potentially a high risk part of tuning.
