How come from a 40 mph roll when I floor it its so sluggish? Does the Auto trans eat up that much power, dang, i barely pulled on a probe, but i did pull on it around 80mph, ,slowly but surely. My car from a stand still (drag, track), its quick as hell?! How can I fix this? Besides getting a manual?

 

Shift to 3rd and let the rpms build then shift to 4th.

Dunno mines not, it still has tons of power at 40 if I punch it.

 

I just left it in D, and floored it...

Guess its not that bad, physics was on his side anyhow.... He was already coming around me at a higher rate of speed than I was, probably from the looks of it, he was coming at me around 50-55 ish while i was doing 40, and as soon as he got next to me I floored it and we stuck until around 70, 80, then i was a car and pulling. I guess I expected to just LEAVE! I really wanted to catch a light with em, I know I would have spanked it.

 

True physics all ways has a factor at speed, but at 40 mine usually downshifts into 2nd and pulls hard does yours not do that. Our cars typically pull very hard in 2nd 02/03's.

 

you can drop it to 3rd, but you will pull harder at 50. 40 mph is not a good number to start on. at 40 your supposed to hit high 2nd and should shift right into third. but sometimes it shifts into third which pulls a lot slower. autotragic!

 

Mine never goes into third.

 

watch when your tranny starts slipping. then it will start happening. probably it won't happen to you, but mine sometimes drops to third.

 

Weird I will look for that, thanks.

 

You really need a VB mod dude.

 

I dont know what you guys are complaining about , go drive a 3.0 auto and then tell me your 3.5 auto is slow. If I punch it at 40 I get nothing til I pass 4.5-5K above 50-75ish (2nd) the car pulls pretty well but mostly just bog. Unless your making some serious power the autos gearing sucks IMO.

 

It depends on what gear the car downshifts to. If it goes into second the car will feel fast. If it goes into third it won't feel any near as quick. My car seems to make a different decision everytime. Of course you could manually shift into second but everyone says this puts strain on the tranny. I'm not sure why it would but that seems to be the common wisdom.

 

I ran a 02 GT 5spd from 40-100 and got pulled about a car. Then we ran again from 50-100 and I was door to door with him until 100. 40 is a low rpm to start a race from as you can tell from the results of the GT run. BTW we both had a passenger but his was about 100 lbs heavier.....

 

I had a 170lb passenger and just filled my tank, my car stayed in gear, it didnt really kick down all that fast, it took a while to kick down a gear, the probe GT was supposedly souped up, he was coming back from the local street races. But I put it to shame, my passenger was talking smack while I pulled away slowly but surely. From 20mph rolls I usually never lose, but from 40-50 rolls thats a diff story.

 

The posts above are right - that's a tough speed to start from (you have to force the right gear, and it's still not optimum). I tried it today, and when the tranny shifts to 2nd you start at about 3 - 3.5k rpm - takes a while to get to the 4k jump.

One thing's weird about the 3.5 jump at 4k; you'd think the power curve would show a spike there, but from SteVTEC's dyno charts there's no indication of a torque increase...?

Also though, I think it's a perception thing. We 2k2 / 2k3 folks get used to blasting just about everything off the line because of the massive torque, but we don't have anywhere near that much advantage from a roll. So it feels "slow".

 

from a roll at 20 our tq kicks in, but as someone said when racing the GT 5spd starting at 40 it will not pull as hard as it would if you started at 50. thats why when i race from a roll i tell them to start at 50. =) 40 is a tough speed because it is HIGH 2nd or MID 3rd. if your lucky and it hits HIGH 2nd then it will be a good race, cuz thats when our variable intake kicks in. but when you downshift to third, then you won't start pulling when you hit 4.5k.

in my experience, when i start at 40. it sometimes downshifts to 2nd at about 5k. other times it downshifts into third at around 3-3.5k. as you can see you will have a better start if it downshifts into 2nd gear. oh yea and starting at 20 mph i peel out, on an AUTO!

so all in all, 40 mph roll isn't the best speed. so you should start at 50 mph.

 

if you floor it in 40mph it downshifts to 2nd and its in 3k rpm...i dont know how you got to 5k rpm. in 2nd 5k rpm is 60mph

our 2k/2k1 has max torque at 4k...the 2k2/2k3 has max torque at 3750 i think. so when you roll from 50, you get max torque right ahead in 2nd. when you roll from 40mph , its 3krpm so it takes a little bit of time to reach max torque and to get the car moving like its suppose to.

also 40 is high 2nd?! wtf are you talking about? 40 low mid 2nd(3k) and 40mph is low 3rd(2k rpm)

 

oh crap, your right, i was talking about when your at 60. yea it didn't seem right either when i was posting it. but starting at 40 mph roll will sometimes not get the best start.

 

 

50mph in 2nd gear is the sweetspot on autos in the maximas...right on max torque. i bet with the 2k2s you just fly back when you floor it there lol

 

at 40 mph shift to 2 with your foot barely on the gas (so it will shift smoother) then mash it. You should get pinned back. After that, just put er back in drive or manual shift. passing at 80, drop it into 3rd and own whoever you race. good luck

 

yeah when i beat a wrx from a roll it was from 50. from 20mph my car flies, from 40 the auto gets confused and never does what i want it to do. so i usually never floor it at 40. maybe it was a perception problem with the probe. he could have been coming faster than you thought and when you pressed it he was next to you but going a good 20mph faster. and dont forget, we drive maximas not vettes so they are quick, not fast.

 

did you get the ecu tsb done?? if not, then that may be the reason.

 

I met up with him today and he said he wasnt ready!
Got em at a light and hehhahahahehahehah, he must have been asleep, from 0 mph - 60mph I was 3 cars ahead easliy! So much for being ready, but I was, honestly i was kinda freaked when he said "i wasnt ready that night", I thought he had NOS or something up his sleeve. After the race he asked If i had S/C or NOS; I said nope, just i/h; He didnt believe me, I also told em I wasnt ready the last time we raced also, he did his usual burnout and took off.


true true, It was going a bit faster than me going around. But I held my ground.

yeah i had it done.


Thanks all for the tips, I'll wait till 50 before I punch it next time.

 

this guy is a ricer man. excuses are only made by losers. if he won even if he "wasnt ready" he wouldnt have said " i wasnt ready but i still beat u" face it, his car is slow, he cant drive your faster. dont listen to his bs.

 

My 3.0 auto is a dog when I floor it at 40 mph, it sucks because i raced my friends stock volvo s40 from a 40 mph roll and got walked. I wish my max had a 5 speed auto rather than a 4 speed auto. My mother has a 328i and that has a 5 speed auto and it's great. No matter how fast you're going it downshifts and throws in the back of the seat...I love bimmers...How would I do in a race with a 2000 328i vs. my 2000 max SE. Both stock both auto but I have a 60lb box with two 12's in my trunk...what do you all think???

 

I don't know if one is available for Maxima's but get a 3500-4000 stall converter and it won't matter what gear you are in when you punch it. An automatic with the correct stall converter will beat a 6 speed with same hp!

 

You are correct, it will BUT try driving it on the street. It will suck @ss. I tried to drive the car on page 3 of my homepage on the street. Nothing til 4000rpm, then 4K is hit front wants to come off the ground and all hell breaks loose! For drag auto is the best considering your making good HP and TQ.

 

40 is right where the 1st-to-2nd shift occurs under full throttle. i've had this problem too gettin on highways where i punch it and it only shifts to 2nd, with the RPMs around... i dunno 4k? give or take a lil. then it takes a second for the RPMs to build and to really take off. but still... it pulls plenty hard 99% of the time. no complaints here

 

Like I said you guys with the 3.5 have little room to complain. TRY to do this in a 3.0 auto and you'll see what lag really is. If I hit it at 40 its at like 3500rpm I belive and cars id usually take ar right at my door, ive heard a VW 2.0 golf shift 3 times while I was in the same damn gear I still edged him out by half a car but thats still pathetic!

 

heh, automagic gears.

I ran the 1/8th mile today; Still cant beat my old time, The best I could muster out was 9.41 @ 76.70 mph

RT .599
60' 2.188

Im going to try to get some Eagle F1's to see if i can get better grip off the line.

Anyone know how to calculate 0-60mph time using the 1/8th? Im old GTECH says its 6.0-6.3

 

No no, not true! I have a 3600 rpm stall in my 98 LS1 Camaro and it's fine on the street. Quality loose converters like the Precision Industries I have pull at very low rpm. It's a steady pull just like the factory except the rpm go up to about 2500-2800 on normal acceleration.

 

What I do is let the Max build on its on to about 70-80mph then tap it to the left into 3rd press the gas, and watch the VQ35 take me to 110 easily then put it into D and then watch the VQ35 take me to 125, then I shut it down cause im "skeered" of the VQ35

 

Is there any chance that you're going to try out an aftermarket torque converter?

 

It would take reprogramming with a converter for proper transmission operation. When I changed my Camaro the shift points went up to the revlimiter and the transmission converter would not lock up without programming. I know of no programming for Maxima's. I added exhaust and an intake and my shift points went up during the winter where I was hitting the revlimiter already. With a converter it would only get worse.

Believe me, a converter would make our Maxima's come alive. As bad as the car falls on it's face now at shift it would make a world of difference. I would venture to say a 14.5 car would become close to a 13.5 car with traction.

I hate to say it but this front wheel drive is really not a car to start hopping. It is too difficult to get a good hole launch with front wheel drive. Not saying it can't be done but all things being equal a front wheel cannot perform like a rear wheel drive.

 

Well im just saying from what ive seen with my own eyes, I dont know much about upgrading converters to be honest. I know for a fact with a RWD like the LS1 is makes a world of a difference that is why I sat for drag auto is the best period. Fun factor, the 6spd is the hands down winner but regardless the only reason im kinda weary about getting the auto is due the the fact mine currectly is an auto and it shifts slow and just sucks. Nor do I know how much power it can handle even if its an 02+ how much can the clutch packs possible handle be4 the disintigrate, doesnt take much with the 3.0's ill tell you that. Btw fo you have a link or something for the converter you are talking about that hold at low rpms. From what I know the chevelle that I drove has like 10% of the coverter holding and just slams you back at 4000rpm and violents accelerates to the point were your alomst afraid of the damn car. (kinda liked it though )

Proving this thread is right, this is sad for me then because I got pulled today by a Spec V from 40 and it was also about a car's length. (no passengers)

 

dayng! Watch those SPEC V's, what mod's did he have? cause from 0- 95 mph I rape em. this is all at the track. The fastest one I've run , ran 15.0
