I saw Motor Week, now I'm skeptical of the 14.4@100mph is the 2002 Altima
I just gone done watching Motor Week. They weren't using the 1/4 mile track equipment. They were using an on board accelerometer (aka fancy G-tech). I'm skeptical of the Altima's 14.4@100 for a few reasons. The first reason is that with an on-board accelerometer, wheelspin greatly influences et and trap speed, for the better just like with a G-Tech. The use of a 5th wheel and other measuring devices like what C&D and MT use are more accurate. Another thing that really caught my attention was the huge trap speed of 100mph while most other mags get 96-97 out of their Altimas. I'm sorry, but a differene of 3mph is huge when you're correcting your ets. If you guys caught Motor Week, you'll have seen them test the new Cobra to a 13.7@106mph and the new Bullit to a 14.1@105mph. I'm sorry fellas, but these trap speeds are well over 3mph higher that any other mag has gotten out of the Stangs. Actually, I've never seen a test of the Bullit ever getting a trap speed of any higher 100mph. MT could only manage 97mph out of the Bullit and somehow Motor Week grabs an extra 8mph and a .3 lower et. Having a 265hp Bullit running at 105mph to the 320hp Cobra's 106mph is extremely hard to swallow.
I'm still very interested in the new Altima, but I don't think it's gonna be as fast (trap speed wise) as we are reading. On-board accelerometers are well known to post MUCH higher trap speeds than what you'll see at the track. Why? The G-techs give your trap speed at the end of the 1/4 mile and track equipment averages your last 60' mph. Most G-techs read about 3-4 mph higher than what you'll see at the track. The more wheelspin you get, the more the mph goes. I've gotten lots of 14.2-3s@99-100mph in my Maxima.

Well I drove a 5sp 3.5L for a while and the third gear goes well over 100+ (at least indicated). So it might be possible. The problem I do have is with hard launches there is some wheel spin for sure. I think with some good tires it might be possible. Fourth gear came close to 130mph (it was faster than my 2k1 5spd). It has a lot power for a stock car for sure! Head to head with my 2k1 with y/intake it would be close hard to tell. There is no question off the line it is faster than my 2k1 5spd with y/intake...it just has a lot of useable low end torque and I could not get any tramp at all! With some springs, fstb, intake, few other exhaust mods, short shifter and new clutch that thing is going to rock let alone the 6spd Max! Even if it is 97mph that is awesome for a stock Altima! 90% of us on the .org who buy a 2k2 alt or Max are going to mod anyways so at least we have a wicked baseline!

Take a look at their reviews online. http://www.mpt.org/motorweek Their times are consistent and reliable. For the 2000 automatic Maxima they got 8.0 and 16.1 @ 86 MPH. That's fairly average, actually on the conservative side. I ran 15.8 @ 88 on the same exact track they did the Motorweek testing on. Also consider... do the other sources do their testing on a track, which is smoother and has better traction? And my last point.. the equipment they used is not a GTech Pro. It's a much more sophisticated piece of equipment. The made a switch to an accelerometer about 5 years ago. They used to use the older wheel type of equipment.
Regarding the Bullit and Cobra. Ask the new Cobra owners about the new independent rear suspension at the track. It launches poorly. The Bullit has the older live beam axle.

As for the Bullit, there's no way a stock Bullit will hit 105mph in the 1/4. The 265hp Bullit is no faster than a 260hp GT and most GTs struggle to get over 100mph in the 1/4. 105mph trap speed in a 3300lb car suggest about ~290rwhp. Most GTs and Bullits put down about 235rwhp. Like I said, accelerometers read 3-5mph higher than what you'll see at the track. They are usually within .2 of the track timing equipment.

If the Altima really could do 100mph in the 1/4, it technically means it could hit a 13.7 with a strong 60'. I still say the Altima is capable of 95-97mph trap speeds which indicate lower 14s with good traction.

The drag strip speed will always be a bit lower than the actual speed because of averaging the speed, which to me is less accurate.
G-Techs aren't accurate enough for exact testing, but the Datron or VBOX are very precise. I would trust there measurements.
I once used a G-Tech at the strip and it was within 1-2/10ths of the actual time, and showed about 5 m.p.h.+ higher.

Motorweek has been doing road tests for 21 years. I've been watching it that long as well. Their times are very reliable and consistent. They know what they are doing. Their trap speed for their 2000 auto Maxima road test is 86, but I've run up to 89.1. I can show you other examples of their conservative ET's and trap speeds.
I have a feeling the Bullit is underrated. With the revised intake, cam and exhaust it should have more than 5 HP than a stock GT. On the Corral, there are several that have gone past 100. Here's one example... 13.83 at 101.52 (stock). One guy dyno'd close to 240 HP and 275 TQ. Here's another dyno example, ----239.8rwhp and 281rwtq (SAE Corrected).
I can guarantee you that a Maxima convert or an Altima freak will hit the 100 trap speed. I'm more certain the 14.4 is attainable, especially with an intake.

What they were using is called >>>>>
a VERICOM PERFORMANCE COMPUTER. I have one and use it constantly to measure 0-60, hp, etc. it is like a Gtech but is more expensive and is very very accurate. The higher MPH at the end og the 1/4 mile is because the gtech and Vericom measure the MPH at the END of the 1/4 mile where as in the track they measure the AVERAGE of your MPH at the last 60 feet ??? Something like that which will be lower than TOP speed at the end of the 1/4 mile. As for wheelspin it will not really affect the Vericom, because it will still be measuring your progress through the 1/4 mile like the track. Go here for more info on this thing: [url]http://www.vericom.org/

i think a 14.4 is possible. if you think about it, people running a 5th gen maxima with intake/ypipe are capable of running a 14.3, than a 3.5liter engine with a flatter power band and more torque is possible. remember, the car is 50lbs lighter, which basically, is nothing, so lets just say they weigh the same. And since max power is at 5900rpms, i say a 14.4 or less is possible with a good driver.

I've never been a fan of the 5th gen Maxima. It seems to lack the refined look of the Altima. Plus, I'd much prefer a IRS. Dave
