I am looking to replace my 95 SE 5speed and will consider a auto 130 or 135, anyone do any testing for 0-60 or 1/4 mi times for a mostly stock car? thanks.

 

96-99 I30 auto 0-60 under 8 sec

2000-2001 I30 0-60 over 8 sec

I35 7.1-7.5 sec

 

I've pulled a 6.6 0-60 in my I35 when it was stock.


And if I recall correctly, most magazine tests placed it at 6.9.

 

Ive done mid-7s in my totaly stock 2k I30 and that was with a slow shift into second. Now that I have the trany fixed I will do another 0-60 in the same spot.

Oh, I just thought I would add this. Talked to the dealer yesterday about how mods would affect my warrantee. Now its time to unlock the cars real potential

 

meta how did you accelerate.. did you just floor it with tcs off or make it accelerate as fast as possible without peeling out?

 

Well, I personally have not, but my next door neighbor says he ran 14.4@9x in his stock I35. Not sure why he bothered taking that thing to the track, he has an 11 second GN and a 12 second M3, and a C5 project. I can ask if he has a slip, but I doubt he really cares what his I35 ran.

I did find something rather interesting about the I35. Let me know what you think. About a month ago I almost bought an I35 for my mom, so I called the dealership I always do my business with (and one of them is infiniti) and they had three '02 I35's ready for me when I got there. They all had the same packages and rims. One of them was considerably faster than the other two, and each were completely stock. (underhook check, exhaust welding checks, etc.) So I got another buddy of mine to go get my I35 and see how it compares to the "faster" I35. We only ran them from about 35 rolls because it would eliminate any form of drivers error. My I35 pulled 1 car length from 35-75, with the gap beginning to widen as the speeds continued. So, this tells me that there are some huge inconsistancies with the VQ35DE (which is supported by many of the altima/350z/g35/maxima times)
So what sort of power difference would be needed for one I35 to out pull another I35 by 1 car length. We are not talking about aged cars, so we can basically throw out the concept of lack of care. All cars had under 30k and were certified.

 

I have VDC rather than TCS, but still, I turned VDC off, brake torqued to around 1500 rpm and launched, trying to minimize wheelspin. That was also on my fairly crappy potenzas. I imagine I'd hook a bit better with these new tires now..

 

Hey Meta,

When you say 'brake-torqued'... is that what the rear wheel car drivers call power brake? I haven't tried that, although now that you say that, seems like it could work. With the VDC on, the car just robs all the power under full throttle acceleration, but it smokes the tires severly when VDC is off. I need new tires on the I, any recommendations on brand/style. I have the Q45 rims with 245/45/18 Michelin Pilots.

 

Meta,

If I understand what you mean by "Break-Torque", hold brakes, hit gas, get off brakes, Isnt that kind of hard on your torque converter? Hopefuly it will die before your warrantee runs out.

 

Yeah, it's also known as power-braking. The trick is to turn off VDC, and let off the brake and kind of modulate the gas pedal to get as much grip as you can while minimizing wheel spin. I think your 18s (weight) are probably slowing you down, and the smaller sidewall isn't necessarily a good thing for drag launches.

As for tire recommendations - Michelin Pilots are some of the best tires out there. If you want better grip, look for some sort of Ultra High Performance tire on Tire Rack.


Yeah, it's probably hard on the TQ converter not to mention the stress it causes on the brakes and transmission itself. Thus - I don't do it that often - only occasionally at the track.

 

Consumer reports has it at 7.5

Edmunds.com has it at 7.1 eith brake torque

Did you test it with a g-tech?

 

If it were that high how could my neighbor have pulled off a 14.4? Not to mention why would it be so significantly slower than the Maxima auto? Edmunds.com says, "we torque broke this car and launched it hard?"

 

Calculated from trap speeds and 1/8 mile times.

As for published figures..

Edmunds has it at 6.9:
http://www.edmunds.com/reviews/compa...7/page013.html

Carbuytip.com says under 7:
http://www.carbuytip.com/car-reviews...initi_i35.html

 

Yes your absolutely right 6.9 for edmunds. My mistake.

Here is the link for consumer reports which has it listed at 7.5

http://auto.consumerguide.com/auto/n...x.cfm/id/37928

And as far as 14.4 1/4 mile? Thats about a second faster than anyone has been able to get. even edmunds which has 0-60 at 6.9 has the 1/4 mile at 15.2. Your friends car is probably a g35, or he's got a 50 shot of NOS, or he may just be pullin your leg. I dont want to argue and call you or your friend a liar, but if you make statements like that back it up with a slip.

 

An I35 is as fast as a 2K2 auto maxima. So there is no reason it should not be able to run high 14's maybe even mid 14's on a cold day with a good 60'. I can believe a 14.4 if the situation was right. I have been to the track with a 3.5 auto max and seen it run mid 14's in person.

 

Agreed, but it may be a tad slower than the 02 Max with extra weight and cefiro its been proven time and time again here with many 02+ Maxima autos in the mid to high 14's including myself. Expect similiar times with the I35

 

The idea that the I30 or I35 is much heavier then their couterparts is way over played. They really are not heavier.....50lbs or so is it. My I30t 5spd with every option weights a tad over 3200 with me in the car (this was on the scales at the track), which is not any heavier then a 95-99 5spd se with all options.

 

what psi do you guys suggest for the tires when launching an i35 on the tracks?? i heard something like 32 psi is ideal for grip and less spin

 

Seems that different psi work for different people, I go as low as 23psi if I need to......32psi is what I keep in my tires daily so that would not be lowering it at all.

 

Ditto what Mike said...32 is about what should be in your tires for street driving.

I would do as Mike said, lower the PSI significantly more than that...I wouldn't hesitate to go to 20 psi....just make sure there's a pump nearby so you don't have to make the drive home like that..
