dash command, at least the version I had in my 350z carputer did not have that, but I would not trust it IMO, the software, at least then was a bit flaky, at least then it was.

ill take that if its from the ECU. this would be the most accurate since its just reading the speed sensor like your dash gauge is! but if its GPS or something, id rather have a video.

I think for 1/4 mile times, it would not be close enough (the measurement of distance by the car probably ain't that good). For time to speed, I'm guessing it would be passable (it is reading'speed from the car), but I'm not sure which is why I'm asking.

Anyone else?

hmmmm maybe put the cars weight with your weight then since that will be the most accurate.

hey man 6 seconds is fast! my wrx could run 11.7 in the 1/4 with a 6 something 50-100!! but you could never do that since you're RWD. but its nice to know, take the drive train out of the equation and we could run together on the highway or where we're supposed to, on a race track!

The point is that this car makes about 275rwhp, it's time is going to be similar to cars like the Evo with the same weight to hp ratio. The variance you get would be so small that you really have no way to test this unless you have a data logger than can do 10 hertz per second (phone is 1). You can essentially get the same by looking at the trap speed in the quarter mile. It doesn't matter. If you look at the trap speed, you will probably get the same order.

Calling names doesn't help with your argument. I can try for as many times as I want, but I am not going to beat a stock nismo with my sport model no matter how many times I try in a straight line. There is something called physics.

What gear are you supposed to be in for the pull? That's going to affect things quite a bit.

Doesn't matter. Any way you think is best. My WRX and buick I was at 2000 rpm and went for it like a dyno run. The WRX I think was all 3rd. The GS was 2nd into 3rd.

Whenever i get a chance, I'm going to give it a shot both starting in second and in third. My money says I'll be faster starting in third rather than shifting, but I've got more power down low than a NA Z.

Play with it. Only rule is don't cheat. Road must be flat. No down hills.

It's Houston. Everything's flat. :rofl2:

I was already wondering this as well. I have to agree I think starting in 3rd will be faster. Sucks we will still have to hit 4th for that last 5mph

I think it would have to be third. You'd be at a pretty high RPM in 2nd, even at 50.

Not exactly what your looking for but I had this video from a couple weeks ago. 60-120 going up a slight hill. Probably a 3% grade or so. Boost is right around 8PSI. I will try and go out tonight and get some more video on flat ground

my car back with 60hp less than it makes now https://www.youtube.com/watch?v=9rPmJC9WYQI

you can notice how its struggling to climb the last few hundred RPM. Thats where i made most of my extra power when I tuned it again later. I added a lot of timing up top and it really climbed.

an older video... this vid sucks, but since the camera was mounted to the car, i had both hands, and you can see/hear how i powershift it when im full throttle (i didnt on the first shift for some reason). I dont ever let off when shifting under full throttle. never had problem, original trans. https://www.youtube.com/watch?v=gZUBgVFIFus

funny as hell.. i went forever without putting the velcro behind my boost controller. its in the cubby. if you watch carefully, you can see it fall out and swing by its wire from the first shift lol.

But you can run through the gears, whatever's faster. 2nd at 20mph will be fine then redline it into 3rd and 4th if need be.

I count 4.3 seconds. Fill out the format and I'll add you to the list at number 1.

Well, I will fill it out with the numbers it was making when the video was recorded. I didnt get any video this year after retuning it to higher power.

phunk, 2009, Nissan, 370z, Stock weight plus TT parts, 6 Cyl, Twin Turbo, 8 PSI, E85, 524RWHP, 401RWTQ, 0.0 1/4, 0.0 ET, 0.0 1/4MPH, 4.3~ 50-100.

I have taken it to the track but I ran a very painful and miserable 11.6 just fighting traction. It can be listed if you want a real world example of how useless the power is in the Z without slicks. No launching allowed from this car.

Nice. Whats a 03 370z though?

oops... that comes from having a 03 350z for a real long time.

for the link you want to do, the best i can think of is to click on the post number. that will take you to just that post with a URL. copy that URL, and use that as the link in your post. actually, click on the permalink button instead and use that URL

So its a 03 350Z in the vid?

Ok I got it. When you click your name in the list it will take you to your post of mods and story, post 59.

Oooo add the vid link to post 59 also so people can watch it with the mods you have posted.

its a 2009 370z, I sold the 350z last year

(Last try) Okay... last post, but this is the sh1ttiest video ever. You can make out the 50 mph marker, and 100mph is when it bounces off the limiter. I took TCS off and I tried a ghetto mount but the effing phone wouldn't focus. Not only that but the steering wheel cuts off the top of the speedo. I needed both hands because the car was at the edge of traction and I could feel the car squirming the entire 3rd gear pull. I counted 5.4 seconds using the youtube trim tool. I attempted 2nd-3rd shift pull without TCS, but 2nd gear was spinning the whole time. Stock Bridgestones just aren't working all that well. It was about 50 degrees outside so hard rubber and cold pavement don't help.

Edit: 7500rpm is 97-98mph. Bouncing off the limiter is about 7700rpm. That's 100mph.

nice. I got 6.1. since I wont be biased, ill do my best to get the times since only one person will do all of them. you definitely need a better start. you can knock maybe 1/2 second off this. I like 2nd at like 2k then run though the gears! that way you blast past 50mph instead of creep by.

Yeah, I thought that as well, but I wasn't sure if it was fair or valid to already be WOT and fully pressurized. I'll do another later today.

according to the rule, it was mentioned that we could start earlier than 50mph and go thru it ... if we go by that I estimate 7 3/4 sec

nice! glad to see an all motor. man Im surprised its not faster. I thought from a roll the 370z would be as quick as my wrx. i bet lap times though it would be faster and im sure the wing doesn't help top end speed. ill have to find some wrx threads on the tracks.

I timed it several times, its hard to get it just right out of that corner with the wheel spin it looks like and I notice youre not 100% throttle till after 80kmh. looks like you get on it 100% right before 90kmh. ill have to test mine soon since i don't have a wing, see if that helps any.

yeah at 4:00, its always been one of the hardest tight right hand corner to any 370z because of a weak VLSD / fuel starvation and I also suspected some issue with the tranny as well because it rely on its fluid to properly lock the converter. (1.0+G corner)
adding the big splitter and wing doesn't help

but I would guess maybe a flat 7sec for the fastest N/A 370z
using a proper datalog tool.

I Just went threw my phone and deleted all my Speedo video's. Trying to dig some up.. :stirthepot:

You did this in uniform........awesome.

I will jump onboard with this once I get my car back from UPREV. My CSF radiator is leaking from the upper hose neck AGAIN!

Ok, the results on mine was 6.5 seconds exactly after using an editing program to see the time more accurately. Also it was a on a run I started from a moving roll at just a few mph, I did not start at 50mph. Also I agree we need something that pulls of the ecu to know for sure, using the speedometer is wildly inaccurate IMO, but its all we have I know.

Vid? Format?

It may not be 100% accurate but we're talking about thousands of a second, maybe a tenth if difference. The difference of 6.4 or 6.6 isn't the end of the world. Gets you on the map with other cars and other Z's to know where your at.

A crack?

Wonder if data logging is even accurate. If you change tires/wheels it should throw off the speedo, whether on the dash or in the ecu. Either way though I guess it wouldn't matter more than a tenth or so.

More than likely blown internal welds. CSF replaced the first one after inspection and my current has been sent off to them for inspection. ZEROLIFT installed the first and UPREV installed the second. UPREV will be installing the third, if CSF replaces it. Otherwise, I will be in the market for a new radiator and I am not feeling Mishimoto either.........

Your tag is to your first post. So add whatever you want to reflect the 5.4. I'd add this vid and then whatever you want to say.

when spring comes around i'll challenge you on this :stirthepot:

nothing is better than a little competition right? lol

i am curious as to how we are roughly the same RWHP but you have headers/TB upgrade/etc. makes me worried if i go spend money on all that i may not see too much gain due to the diminishing power gains with adding of multiple upgrades.
