turbonator?

 

Imo, dynos are rather worthless. Put two cars side by side on some pavement, eliminate traction issues (for the most part) by doing a rolling start from 40MPH+. Repeat a few times.

 

im the guy he's talkin about and i only saw 4whp gain from uprev custom tune by jared at uprev in austin. They said my computer learned my mods realy well, and thats becasue i floor the hell outa my car everytime i drive it. Try it out drive your car hard for a week then go out and race someone who usually beats you by a car or 2 and you should be able to take him. dont belive me just try it. my car is an auto 04 g35 5at and its yet to lose to another g with the same mods or more 6mt or 5at.

 

smart man now youre thinkin like me lol. but what i you can spin from 45 or 50 lol?

 

lol dont hate cuz ur slow haha

 

The 234.7 HP Z is a performance model, with stock 18's.
I have 17" wheels that I think weigh less.

The other Z was running conventional oil.
I run Synthetic.

The other Z has the drop-in filter 24/7.
I only use mine at the track so it was pretty much new. (clean)

And, I think, the biggest factor...

We were both running our cars hard on the "test & tune" track that day but he was new to the sport (autocrossing) and I was/am not affraid to stay deep in the tach.

Our dyno pulls were back to back. Same day. Same dyno. There was a difference in the power our two cars were putting to the ground that day. What ever the reason, I don't see any way around that fact. (unless the dyno suddenly became uncalibrated in the few minutes it took us to pull his car off and strap mine down. But it seemed accurate with the other cars that pulled that day after mine, so I doubt it.)

BTW: I know some areas of the country only have 91 octane, but here in SW florida 93 octane is the norm and I only run Shell gas. ( He runs "premium" but I never asked what brand. ( I don't think it would make that big a difference since, down here, almost all premium is 93 octane)

 

^I think it maybe that more dyno's have avg'd less then compared to this particular Z dyno.


Are you kidding? I imagine most Z owners drive the vehicle as it was meant to be driven...with spirited enthusiasm...

 

What is a hater? Is that the same as NOT gullible? We just happen to have a little more experience and exposure than you, that's all. It's no skin off my nose what the OP or anyone else dynos. I still have the same car, same house, same job, same family as before. And it's your right to disagree, if you want. I wouldn't hate you for it. BTW, I stopped driving the hell out of my car a long time ago, even if that meant I would dyno 10hp less that it could otherwise.

 

I have read through a few of these... To inform everyone the dyno is legit and the car is aswell. We did 86 pulls that day and made 261whp and 251ft/lbs. I am dynoing the car tomorrow aswell so I will take a video to show.

Just got the dyno sheet straight from the tuner.

 

If that dyno = a stock '03 350Z, then the explanation could only be one of 2 things...

The 350Z is NOT stock
or
The dyno is NOT accurate.

However, I suppose you will come back tomorrow, claiming 300rwhp after 300 pulls...

 

They guy's car is legit as it is stock. And the dyno he is on is legit as well, not sure it it is accurate or not. He does live by the coast which a member above said it might effect numbers..but i'm not sure if that is correct for not.

 

So you claim the dyno is legit, then add you're not sure if its accurate... Kind of a contradiction, eh?

Regardless, something does not equate here.

 

i meant he is actually using a dynojet dyno. Not just making a graph up or something.

 

...WhAT?

 

Oh, I don't believe the graph is made up, just saying that a stock '03Z will NOT make 260rwhp (regardless of the amount of pulls conducted) unless the vehicle isn't stock or unless the dyno corrections #'s are heavily skewed in favor of high results.

And if the OP actually believes that vehicle's dyno results are an accurate reflection of the power output, then he is extremely naive.

 

true. I'm still interested to see what's going on.

 

Didn't think about that part too much...

Hrmm, 86 pulls in one day... So supposedly this shop has no other customers as well, because they spent the entire day doing dyno pulls on a stock 350Z for no other reason except to see if the numbers got higher. Not to tune it, check gains from added mods, etc...

This thread is starting to get really deep.

 

i don't believe the place he got his car dyno'd at hasn't been open completely yet. Sorry if this sounds confusing. PM me for a better explanation.

 

Maybe you can just better explain it to all of us - the suspense is killing me.

 

The shop is not open yet.. We did 80+ pulls to test everything from indoor exhaust system to the computer. Everything is legit and we have had other cars on the dyno before which gave realistic numbers. I have had a number of 350zs and know these results are high. Although I do not think 246whp is that incredible. So we gained 15whp from repetetive runs. I know that NA cars love heating up so I dont think the numbers obtained are that far off. I bought this car about 2 weeks ago from a member on this forum who said the only mods he had were audio and popcharger. Today we put the Haltec in and the ECU was stock. No reflash no nothing. I do agree these numbers are odd but they were consistent and we have had many other cars dyno in normal areas. The car is strong but I can not tell because I have never owned a non-FI Z for more than a month. I will keep you updated if I find something.
