ok here it is, weather was 88 degrees and 70% humidity, this is no excuse at all car ran what it ran. this 1st of all this is my fathers car i dont drive it all the time. second on the street if u nail it u get a nice screeeeeeeeeeeeeeeetch off the line and the car just takes off like a champ.... so 1st run tires where set at 30 psi and 32 psi in the back... right before i staged i nailed it up to the line and the tires screamed!! pulled up to the light, light went green i just stomped on it spun all the way through 1st and second spun passed 60ft mark, kept it nailed the whole way ran a very crappy 15.2 at 93.4 mph... i was very upset now, on the street i just floor it get a nice screetch out of the tires and i go, not at this track and usualy its a very good track... 2nd run i was like maybe the track is better now, ill nail it again so i stomped on it again nothing but smoke so i get totaly off the gas and than nailed it again, spun a tad more and ran a 15.1 at 93.9 mph.... i was talking to other people and they where so mad that there was no hook up, and on an avg there cars where off by a half second.. so judgeing by this the 04 max will hit a 14.6 or 7 on a good prepped track and better weather... there was a really cool guy there with an auto 03 maxima gle with just a cone k&n filter, he showed me timeslips of his car from april when he was there he ran consistant 2.2 to 2.3 60fts and always ran 14.6s at 95 on all 4runs he did back in march. his best run in arpil was 14.48 at 95 icing down the manifold.. lastnight he ran a 15.2 and another 15.2 at 89 and than 91 mph.. with 2.4 60fts, my first crappy run was 2.5 something 60ft second was high 2.4s 60ft... so as far as i can see its not the car it was the track.. but for a humid and hot night trapping almost 94 isnt bad... than to top it off on the way home i stopped at a traffic light and floored it just to see how much i would spin, i had a nice chirp and just took off like a mo fo.. so it was the track i wont say track there was just no hookup there..so as far as i can see that made me run low 15s.. the car is very capable of running 14s easy... by the way the car was 3580 lbs with me in it.. im only like 120 pnds... so the car is like 3460 without me in it.. so there u guys go the times will only get better when and if i go back with better traction and i get more runs to practice the launch, and they prep the track better, mid to high 14s isnt a problem for this car... with my spec v i run 15.3s all day long on an avg and on the street my pops 04 max will beat me from a dead stop by about 4 cars.. high 14s is good enough for me, but i do think mid 14s is very capable

nice, are you going to scan in your slips?

What were your 60ft on your runs?

ga2000

well ill start off in saying im not happy at all with my runs, no traction what so ever... had to get off the gas back on to it.. it really sucked.. my 60fts where 2.5 something on my first run and high 2.4s on my second run.. very bad.. i cant scan it but ill get the time slip and pst on here exacly what it says.. everything was in the car spare jack everything stock.. if i get traction next time and i dont have to get off the gas and back on it to stop the tire smoke the caris in the 14s, but i want the slip to say it.. i lost ALOT of time just sitting there spinning and than on the second run getting off the gas and back on it to stop the spinning... but if i ran 15.1 like this i know the 04 is just as fast as an 02 or 03. 14.7s is very doable.. im just ****ed i didnt get it done yesturday..

I think you should be able to get into 14s with better 60ft.
I mean I had nasty wheel hop and spinning and managed to run 14.7 with crappy 2.445 60ft. It is all about lowering your 60ft. I am pretty sure if I get 60ft to like 2.1-2.2 I should hit low 14s.

Did you get any wheel hop? or did wheels just spin like crazy?
I am afraid of wheel hop, because of that I broke my engine mount.

ga2000

no i just had crazy spinning, it spun felt like it hooked back up and spun again.. it was insane, ive never gotten that much wheel spin in my life evan if i pop the clutch in my other car, thats a stick... i really think it was the track that killed my times. i know the car will do a 14.7 easy stock, ive raced my bro's 03 acura cl type s in my 04 maxima and he runs consistant 14.8s stock in this heat, and i beat him by a car all the time on the street when i dont roast my tires like i did at the track..

JAKE02

Do you know of any 6spd 6th gens that have went to the track?

Man Honestly if the 04 is making slightly more power than the 02 and 03s then I think the main thing keeping us from the higher traps and stuff are the damn stock 18s. I love my 18s and all but im thinkin about some lightweight 17s. I dunno though it seems like the 6th gen would look weird with that small of wheels but i have seen some sl's with 17s and they look ok, anyways dropping sayyy... 10 lb per wheel(if possible) would equal 320 lbs of unsprung weight or whatever it is. thats at least a couple tenths if not more plus with the 17s you get the extra rubber.

JAKE02

I guess if 1/4 mile times are that important to you....I think the 18" wheels look awsome and would not mess with them just for a few tenths faster track time....but everyone has differing values.

Dave B

The only wheels that really affect the acceleration will be the drive wheels. The rears are just along for the ride so you really can't say you'll shed the equal of 320lb in unsprung weight. It will be more like 140-160lbs. Your 1/8 mile will probably improve .1, but after that the differences are not that large. The 3.5VQ has a lot of torque which can overcome the initial bogginess of heavy wheels so don't expect HUGE gains going to lighter rims. They'll definately help though, especially in ride quality, overall handling, and braking.

I think the 04 Maxima's problem is going to be moving it's fat butt off the line and the 0-100' is the most critical part of a 1/4 mile race. Once rolling it's decently strong, but down low it not that great thanks to it's additional weight. I think there will be those that get 14.7s out of their autos, but that will be a rare occurance. The RARE mid 14s the 02-03 autos have hit is because they're lighter which is far more important adding extra power. Heavy 18s with low profile tires are hard to control off the line and they're hard to control when they're spinning (more inertial weight is hard to modulate). BTW, a track surface is almost always going to be more slick than the street if you're running radial tires.

Dave B

Depends on what kind of conditions you were racing in when you did a 14.7 with a 2.4 60'. I've run plenty of 14.7s@96mph with 2.4 60 foots in 50-60 degree weather, but in 90 degree weather if get a 2.4 60', I'm running 14.9-15.0@93mph.

Going from a 2.4 to 2.1-2.2 60' will probably get you a 14.3-14.4. I don't see how you'll get a 14.0-14.2 by just improving your 60' .2-.25. What are your trap speeds like? That's the ture indicator of available power. If you're getting 96-98mph traps then you'll probably get 14.3-14.5 assuming a lower 2.2 60'.

Yeah when I ran 14.7 last week, it was pretty humid and nasty outside. I don't have the exact weather numbers but I can check. It was my first time ever at the track. I was able to run only 3 times on two of which I completely screwed up, missed a tree light, and everything else . On my last ran I ran 14.7 at 96.4 mph with 2.443 60ft.
I am sure I can do better if I just learn how to launch better. I felt like my car really pulled hard after I passed 60ft mark.

ga2000

so u guys think my car is definiltly capable of 14s?

Dave B

Definately capable, but IMO it's VERY unlikely you'll ever see a 14.6 out of that car stock. It's simply too heavy and underpowered to get off the line hard. The trap speeds are good, but most Maximas get high trap speeds in relation to their ET. It's because we just can't 60 foot good at all. If we could pull 2.0-2.1 60 foots (damn near impossible with our low torque FWD cars) we'd be a lot quicker. Look at it this way, if you were to pull a 2.0 60' the numbers would be like this:

14.9@90
14.8@91
14.7@93
14.6@94
14.5@95
14.4@96
14.3@97
14.2@98
14.1@99


Dave

ga2000

i should be able to hit a 14.8 with a 2.3 60ft atleast a 14.9 stock... with my very high 2.4 i hit a 15.1 and with an evan highter 2.4 i hit a 15.2.. i just have to figure out how to launch the car without getting off it and than back on it so the tires dont spin as much.. on the street its fine, but the track the tires just fry

kit99bar

man nice trap speeds especially in that 88 degree weather.

I bet we'll see an 04 pop a 96-98mph trap soon. One of those east coast guys

ga2000

i trapped 93 the whole time all in 89 degree weather, the 03 that was there was trapping 89 to 91...

Dave B

I think the 5 speed auto definately is showing it's strength in topend performance because 92-93mph traps in a 3400lb with no more power than the 3250lb 5th gen Maxima is pretty good. That extra gear really seems to help the cars 50-80mph performance.


Dave

ga2000

well with me in the car im only 120 pnds. the car is 3580 with a 1/4 tank of gas.. so without me in it its around 3460 or so... yup 40 to 100 is very good in the car.. who knows it might be the extra gear or it might have a tad bit more power

ga2000

it does pull hard from 50 to 100 mph

SteVTEC

This violates Newton's law of conservation of momentum.

The front wheels have a certain moment of inertia and require a certain amount of energy to accelerate at a certain rate. The rear wheels are the same and require the same amount of energy to spin up. Just because they are not the drive wheels does not mean they don't have a moment of inertia and don't require any energy to spin up. They do. Therefore, front and rear will both have an effect on acceleration.

Dave B

I disagree The rear wheels do not have a direct connection to the device that is trying to accelerate them. It's much like towing. Sure, running the large rims in the back don't help things and there is more inertial weight, but it's not near as bad as running the large rims on the drive wheels.

I've run with my 17s at all 4 corners, 15s in the front and 17s in the rear, and 15s all around. With all four 17s I'm about .15 seconds and 1mph slower. With the 15s in the front and 17s in the rear I'm no quicker nor slower than just running all four 15s.

Dave

SteVTEC

The 15's and higher profile tires up front would allow better control on launch, so that'd be better than 17 up front and 15 in the rear. But regardless, you still have those 17's in the back. Conservation of momentum means they require extra energy to accelerate regardless of where they are.

Maybe the difference between your 17's and 15's wasn't big enough to be noticeable when you're running with a combo. Have you tried running with your 17's up front and 15's in the rear? If the difference is 0.15s when running all 17's, the difference would be down to 0.07s with running a combo. I know you're a consistent driver, but that's getting a little tough to measure. The 17's in the back are still gonna hurt.
