^^^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

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.

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:

I don't plan to drag race my car on a regular basis, but I'd like to run down to Houston Raceway Park and do a run just to see how it does. The primary reason I haven't done it yet, is I want to wait until all the mods are done and then just do it once.

One thing that sucks, from HRP's rules:
So basically, if I do make it into the 12's, I won't be able to go back without installing a driveshaft loop, which honestly I really don't want to do since I'm not going to be dragracing this car in general.

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.

KingDavid 05-31-2009 02:35 AM

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. ^_^

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.

NinosZPWR 06-01-2009 11:52 PM

Yea man
 
yea man it could definatly get 12's.

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

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.
