We've got a 20% chance of rain at Baytown tomorrow night too, which could really scrap things. But I think if it stays dry, it will probably go well :)

Ugh. All these bench racers...

I don't see a 370z breaking into the 12's without some mods and a set of small diameter drag radials. My last car was a c6 vette that would just beat the piss put of my 370z and I only got it to run 12.8 on RE050A's. Show me your time slips!

In the mean time, I'm not going to spend the money to go run it because I know I would still be turning 13's. :-(

I ran twice last Friday, 7AT with the full set of bolt-on power adders, but no track prep (as in no weight removed from the car, even my giant bag of tools, and normal street tire pressures). Both runs were in the 13.4's. I was also unfamiliar with the track and a bit nervous, and short on time.

I think my launches were subpar, and my shifts were a little late just due to me being distracted by the whole experience for the first time. I'm planning to go back soon on a night where I can get the car prepped and get several runs in to learn the launch, and I expect the time to drop significantly. We'll see how it goes. I can't say for sure that 12's are possible, but they certainly seem within reach.

So you don't see it happening because your drag skills are sub-par?

It's the same thing people said about the HR 350Zs... "oh lawd, they won't hit low 13's... no f'n wai gai". Look what happened.

And we already got an AUTO 370Z that hit a damn 13.1. I put money on it that the 370Z will dip into the 12's with nothing more than tire pressure changes and a good driver.

Hi. Nice to meet you. Could we start over without you flaming me? I'm an experienced racer. No, I'm not the fastest. If I were, I would race for a living. I live in a hot area with low humidity and track times tend to be slow (DA calculations run around 2500-3500). I objectively state the facts and make suggestions to help move this community forward. We have a lot of people speculating on how fast their 370z is. They are currently not that fast with the mods on the market, but not many people are taking their car to the track, or they are not posting their time slips for fear of being mocked. I'm simply trying to get more people to take their car to the track rather than playing arm-chair quarterback.

The fastest time I have seen posted for a 370z with no modifications is 13.36 seconds and the fastest time that I have seen for any 370z at any level of modification is 13.21 seconds from our own "ZforMe", but his DA calculation was -565, which is going to produce a very fast time.

So even with mods and very favorable track conditions, the 370z is only hitting 13.2 second quarter mile times. That is why I said I think it's going to take a set of drag radials to get into the 12's.

If you disagree, prove me wrong.

^^^Take it easy^^^

As soon as I get My car to hit 2k miles I am going to take it to the track and I will post my times up for everyone to see...... But With what I am seeing they should be low low 13's



DAN

FWIW, my 13.4xx runs were at a DA of about 1500, which makes them line up better with ZforMe's results I guess. And no, I still haven't scanned the slips (I don't have a scanner here, and I haven't been by Kinko's lately, sorry).

Edit: And I do plan to get back there soon and do it right, hopefully this Friday.

I went to a handy-dandy internet quarter mile et calculator to crunch some numbers.

Edmunds inside line tests this car at 3359 lbs. With a 170lb driver, that is a total of 3529 lbs. Plug that into the ET calculator with 332 flywheel hp and it says: 13.49 seconds. Pretty much in line with what car magazines have been getting.

So how much power do we need to get a 12.9 at that weight? 380hp according to our internet calculator.

Using 17% drive train loss (that whas the calculator's #, not mine) that means you would need a baseline dyno run of 284whp.

How much would we need for a 12.9 second quarter mile? 324whp. That means a 40 whp gain would get us there. Sounds reasonable. Just hasn't happened yet.

With some of these initial dyno numbers coming in under 260 hp I was worried that Nissan fudged their power output numbers... but it looks like that is not true.

Anyways, just some food for thought....

don't laugh but the only rule over here in Montreal is that if your car runs faster than 12.99....you need a helmet......if not....just drive the car.
that's it :ugh2:

They make us wear one here if you are faster than a 14.0. lol

So if I put a turbo on my rotary engine with pistons on my honda oddyssey I should be able to hit high 12's?! My oddyssey does have the GT-R emblems on it you know... Limited edition...:roflpuke2:


Sorry guys! I went there!

Well I had never been to HRP before, so I was just going off the rules posted on the website. Let's just say being there in person was a completely different experience, and I wouldn't at all be surprised if someone ran 12's with no helmet and faulty brakes there and got away with it.

I don't know. I/H/E and a tune has yielded numbers as high as ~345whp. If it comes stock with ~260whp and runs 13s like that, someone might be able to break 12s. But talk is cheap and so is bench racing. So I'll wait for some results. ^_^

^^ +1

Well said.

I've got around 350hp 360trq and i'll usually run right at 13.01 on stock rubber full pressure. Maybe that will give you some comparison.

My 60's are also pretty terrible - 2.0+

I ran a 13.0 at 109 and got yelled at for no helmet. MPH is also a factor at HRP.

Yea man
 

yea man it could definatly get 12's.

used to be 12.99! i dont like the change :icon17:

15 days later, he forgets his own thread, lol.

http://www.the370z.com/tuning/4594-i...o-results.html

You made 343whp.

I want to see Phimosis take his car to the track. According to his dyno results and the little calculator, he should be running around a 12.6xx - 12.7xx. I'd like to see what some of these guys are running that are in the 330+WHP range. I could care less about all this talk on STOCK Z's. I want to know what it is capable of in the long run, after parts.

To run those times you all are throwing around you must be some pretty good drivers -- or yappin.

Due to other scheduling constraints, I likely won't make it back to the local 1/4 mile until June 19 (two weeks later than planned). And by then I'll probably have a few more mods going as well, so I won't even be able to tell easily how much change was me getting better vs the car :(

Internet calculator. Lol.

Someone APPARENTLY ran a 12.8(9) with a bone stock Z on DRs in the back. I read it somewhere on here. Don't know if proof was ever posted up though.

And I would like Phimosis to run on DRs. See what he gets. Could be interesting.

it's not going to break into the 12's where I live. :-(
I have been out of town, but our last "test and tune" was last Friday. If I had went there after work, the DA would have been 2860 (Famoso raceway, May 29). A 12.70 sec @ 107 mph car at a DA of 2860 corrects to 13.25 sec @ 105 mph.

The seat of the pants dyno tells me the same thing. My vette ran a 12.8, but is way faster than my 370.

To be honest, my car was "bogging" from 5,000-7,000 rpm. I thought it might be from detonation (and subsequent timing retard) because the weather was almost 100 degrees and my timing is advanced over stock. So, on an empty tank I put 5 gallons of 100 octane unleaded in it and dynoed it. The breeze was running the wrong way through the shop, helping to heat soak and keep intake air temps sky high. The ambient temp was already 98 degrees. The runs were on a dynojet. The best run? 290hp. :-( with intake, exhaust, cats, headers, remapped ecu and race gas... Only 290hp. There's just no way I'm going to get into the 12's on the track where I live.

Thats when you take a weekend cruise and run at a diferent track! :)


DAN

Damn, I have been tryin to see some real times with guys who are completely bolted on. Like I said, I could care less about the stock time because let's face it, no one who actually owns the car would just leave it be, lol.

Actually I posted multiple 13.2s splits with nothing more than the Stillen G3 intake on my 7AT base and this was on the track in Fayetteville, NC which is notorious for being a slow track due to it being slightly uphill and terrible 60 ft traction. I rarely ever had tire spin probs and was seeing constant 1.9 - 2.0 60 ft times.

As it stands now, I just moved back to Texas and am home visiting in Houston so I plan to try and make it out to Houston Raceway Park this friday night June 5th to see if I can lay down some better times. I would love to get some of you other houston guys out there this friday, PM me on here and maybe we can arrange a meet up out there or something.

Famoso is a great track. One of the fastest in the country some days.

On your fastest run, 4/13/09 @ 8:53 pm, the DA was 389. Your ET of 13.341 @102.889 would correct to 13.333@102.859. Convert that to a 3100 DA that we had on our last track day (5/29/09) and it would be an ET/trap speed of 13.85 seconds @ 98.9 mph, which would universally be considered slow in this forum. hot track in low humidity = slow track.

When your talking NHRA, the limiting factor is traction, not power. If you have 105F ambient temps with 200F Aspalt, you get incredible traction. If you're only making 7,200 hp in that condition vs. 8,000 hp on a track with 65F asphalt, you'll pull a very low ET even though your trap speed is low. On a 332 hp car in those conditions, making 298 hp will kill your ET and trap because traction was never a (big) problem. (I used 90% of max power in both calculations).

Where are you getting the DA corrections? Can you check my 13.212?

Thanks,

I used this: DA Calculator - Density Altitude Calculator - DragTimes.com

So now my time is considered slow because I did it in favorable weather conditions? Thats a bit of nonsense if you ask me! Also your looking up a DA of the time when I posted the splits at 8:50 at night, not when I actually made the pass which was early afternoon closer to 1-2 pm in the middle of the heat/humidity of the day. Not to jump on ya, but you don't take a good time on a good day and turn around and convert it to a slower time in less than favorable conditions. If anything it should be the other way around. I mean yes it sux, but you don't discredit someones posted times because they were fortunate to have good weather at the time of their runs. Weather conditions do make all the difference in the world, this is true, thats why we got a few HR's with 13.1 times even, but hey a timed run is a timed run is a timed run, if you were lucky to have favorable conditions on your side that day, more power to ya, sorry to those that don't tho! But don't discredit someone else's times.

The DA thing isn't about discrediting anyone. It's just a useful way to really compare numbers. Otherwise someone who lives in a bad climate for drag racing really has no way to compete or compare with anyone else.

True, but shouldn't you take the times with high DA and convert them to a more normal condition, then to take times posted in good DA conditions and convert them to bad DA conditions, making the times seem bad?

Well his point was that your car would run a crappy time at his track, not that your time was crappy. It's just a track comparison.

True I guess! Just don't like seeing it that way. I mean I know it sux for him that he has to run there, but use DA calc to his advantage and show what he should be running instead!

The top 335i's on dragtimes have all set the records at Famoso. Someday I'm going to make it out there, maybe fly out for a weekend. But I understand what you're saying.

Well, I finally went out and ran my Z. Worse than I expected at Famoso.

8pm at night, 94 degree track temperature. Density altitude = 3186. Something bad happened with track prep. Guys that I know that run 11.5's were turning 12.5's because no one on street tires were getting traction.

On 91 octane I turned 14.0 @ 101.8 with a 2.3s 60 foot which was all spinning with 3500 rpm launch. Used 8,000 rpm shift point. With traction control on I ran 14.4s. Looks like I'll have to wait until fall to see some decent numbers at this track.
