I went to the track today to tune. to me my times were crap. i have spacers short ram and a y-pipe done. and i am running:
10.5 second avg 1/8 mile times
trapping between 69 and 71
60ft:2.6 - 2.7
r/t: under .5
I have been practicing my launches but with the tune im not seeing much of a difference. I have g35 18's on my car w/ 245/40/18 on front.
is there any advice on what i should do cuz there are civic si's mossing me. its depressing.
i have tried rolling out the line and stepping on it but still crappy launches.
and no cels are being thrown

 

Can't go to the track like that and expect any PB's I don't really see anything that should've made ur times better as you've probebly added more weight than power.... good try though, keep at it, practise makes perfect

 

can you laydown the whole track slip

 

Probebly went to a 1/8th mile track

 

Have you tried just easing out from the line and see if that helps you lower your 60ft? Riding out from the line like I would a normal traffic light, usually gets me a 2.2x (all season tires), if I try to accelerate out of the line and waste time spinning I get a 2.4,2.5 or even worse. Although you practiced launching your 60ft is still too high--are you spinning terribly at the line, or wheel hopping? Still running on the motor mounts that came with the car?
Good luck.

 

Lower the car, get decent tires, change from Y-pipe to headers

 

What Grand hustle17 said.. I was running 9.2 9.3 1/8 mile. After I lower my car I ran 9.1 1/8 mile. Makes Difference

 

that 60' sucks horribly. I dont know what youre doing but its not right. Did you drop the pressure in the tires?

 

in a auto it shouldnt be too difficult to pull 2.2 60', lowering the tire pressure also help (22psi)... good to see you dropped times also tedo

 

i only ran an 1/8th i have the car on eibach/illumina setup and falken 912 tires all around. but i did leave the 2 tens in the trunk. but i thought i could break 10 seconds. there was an altima ser running 9.5 with just a intake.
is it safe to run tire pressure that low (22psi) on low pro tires? i have it at like 30psi. but im spinning no wheel hop at all.
when i let it roll and go down on the pedal gradually im still running slow 60ft times. since i put the y pipe i noticed my torque disappeared a bit but my top end rips through

 

Not that I have any drag racing experiance but, maybe you should throw your stock rims on if you have them laying around and drop the pressure like Grand_hustle said. I have the same rim & tire set-up and they're pretty f'ing heavy. I know that losing unsprung weight it makes a difference. I think losing the sub's would help a lil' too, there's a rule of thumb that every 100lbs lost is about of a tenth of a second (about a car length).

 

ive ran 18psi before, im not saying to daily drive on it like that

thats the rule of thumb...

to the OP, im sure you know the basic hints and tips to running good times and ill ask, did you really think with all that weight your car was to perform better than it did stock??? if so why must i ask?

 

What are stock times suppose to be? I would like to believe the 18's aren't that heavy. Does anyone else have a 3.0 any time comparisons?

 

They're about 26 lbs each without a tire mounted (50 each with tires). Even if you stockies are "only" 5lbs lighter it'll make a difference. There's a big difference b/t unsprung and sprung weight. It's not like taking 20lbs out of your trunk. You're decreasing rotational mass, it's a whole different ballgame.

 

There was also a sticky somwhere stating how heavy these are....

 

i saw the stick it said 24. but i thought it was pretty light for a stock rim. cuz the stock 16's were in that area as well. i didnt go aftermarket cuz i dont know when rims get too light for street use. I have bent rims before and i hate dealing with bent rims. what would be a good weight to help my times but be able to take potholes and mainly sunken train track crossings.
im definitely looking into some 17's for the car now.

 

rims dont get too light for street use , you might be thinking a little bit too hard, and if there was such a rim you'd probebly never find it to buy it... the keonigsegg comes with carbon fiber wheels that probebly cost more your maxima yet those are good for street use lol.. get some 240 16" wheels, or if you can find some mellenia 16" wheels, those weight about 11lbs... never the less just find some 16's, whether its 4th gens or 300z ect... makes a difference

 

assuming i find a 17 inch rim what weight should i be aiming for 18 pounds? sixteens are too small for my preference. i have seen way to many bent allow rims im not looking to spend over a grand on rims.
what would be the difference in times moving from the 24lb rims to something in the area of 18lbs?

 

Your only getting two 16's for the track and you shouldnt be cocerned with looks when going down the track... no one cares how good or clean your car looks (trust me) you probebly loose more respect tryna ride down the track all pretty and running crappy times.... get two 16's and when u go to the track just take ur 2 18's off and have fun..... why are you so paranoid about braking or denting or cracking rims ... its only for track use bro... calm down you can also spend a good penny on buying leightweight 17's if that floats ur boat

 

i have been through 2 sets of bent rims and i want rims for everyday use not just for the track.

 

i was really looking to see if any other 2k's are running this crappy but i guess im the only one still running a 3.0

 

14.3 lbs per wheel / 37.5lbs per wheel/tire combo. This will be required for any auto 3.0 trying to improve track times. Also helps MPG's too. 12-15% in my case.

 

37.5lbs with tire? That's prettty crazy man. Those are 17's right?

 

does anyone have drag times so i can see if dropping the weight of the rims is really that beneficial? im aiming for more than .2 of a second

 

??????????........... i doubt people do before and after drag runs as every single race is different.... think of it like this, if you run a 100m with a bookbag with 50lbs of books in it on your back vs running that same 100m with the bookbag with 10lbs of books in it.... its moreso a common sense thing bro.... i dont see how you dont think it makes a difference , why the need for proof, prove it to yourself

 

I'm just looking for a difference in times... I know it will make a difference but I wanted to see numbers...I'm sure those go to the track haven't had the same rims from day one and every run should be about the same with small differences....i ordered some rims already so I will find out on friday

 

17x8. Wheels are 14.3lbs, tires are the difference.

 

I have done this test years ago. I gained approximately .1 seconds and 0.75mph going from a 37lb combo to a 30lb combo on the front tires. You aren't going to get .2 seconds unless you are going from a really heavy setup to a really light setup.

 

Thank you this is the info I have been asking for not all the slack I have been getting for asking. I'm moving from a 25lb wheel to a 18lb wheel so .2 should be attainable on the 1/8 mile

 

Go with a far smaller diameter to effectively change your FD, that will also improve times.

 

not too small though... 16's the smallest IMO

 

no, you go as small as you can go. the benefits to that go beyond changing FD, a smaller wheel focuses mass closer to the center which makes acceleration of said wheel require less power. FYI, J30 15's fit on the 5.5 gen and they weigh only ~14 lbs

 

^^ And that is VERY helpful for a 5th gen AT 3.0L vs say a 5MT or 3.5L AT.

 

the times suffer with 15's, i cant get all technical and explain how but i remember hearing of it, and even seeing it.... good info on the J30's though.. does that wheel fit over the stock 5.5 caliper????

 

...I'm sorry dude but that was funny...but I would say go with some 16s and try leaving at idle

 

Was this an auto????...
May I speak???


16's
22psi
2-2.2K rpm launch
Manual shift
Thank me later

 

Jime ran 15" tires, it's a fairly simple concept. But, most 15's wont clear A33B brakes, but the OP has an A33 .. so.

 

15s that weight the same or less than any larger wheels, have tires that are just as sticky, and have the same diameter, will net you faster times

Anyway, yes they fit over the calipers, myself and another member, both 5.5 6mt, are using these wheels

, theres a reason that 99% of slicks are in 15s and smaller

 

jime has a 4th gen... tell me theres not a difference

whats your point??? go ahead and run it... watch this...

 

seriously? so theres something so fundamentally different about 2000-2003 maximas that they are different than every other car out there? even other maximas that are EXTREMELY similar to them?
