Figured out WHY our autos don't go past 4rpm at tracks
Figured out WHY our autos don't go past 4rpm at tracks
I was messing around the highway (no cars) with a GSR yesturday
and I've learned few things.
when you race on a roll, take your o/d off (so you go on 3rd) then shift to 2nd.
call for the launch and stomp the gas, then to 3rd at redline
now, it won't go over 4rpm, so before it reaches there, turn your o/d off and WOOHOOO~~ rpm keeps rising!!

wow those are pretty crappy times even for a stock auto..... is the track elevated?..... stock i ran a 15.6.... and a certain someone ran a 15.2 on the board =)....

So it can really very alot depending on the year and the trim of the Maxima.

Probably best to look at all the facts before calling someone out on their crappy times...

the 15.6 was with my 17's and my pop charger... nothing else....
the 15.2 was stock AUTO time..... one of the moderators i believe....
deezo ran a 15.4 stock too =)

...I'm going to put the paper filter in and block the OSCAI and see if it makes a difference next week.
My car shifts at almost redline any time I floor it. No fancy lever manipulation or button abuse needed.

do you recall what rpm you launched it at? Did you feather the throttle or just hold it down outta the hole?
jeez with the mods i have, you'd be in 14's

When I launch I go at 1500~2000 RPMs while holding the brake down, works every time. My launches are almost identical every time and there is almost no wheel spin. After I break out of the gate I just floor it and the auto tranny does the rest for me. There isnt a whole lot of challenge in driving an automatic max, I think ive reached the best ETs that I can get with my car because all of my latest times are almost indetical; with little or no variation.
Also you need to understand that there are differences within the 4th gen line-up. 95~97 GXEs auto or manual are always gonna run the fastest stock, period. Before you insult someone's 1/4 mile time you should first look at what year, trim, and mods they have before making any comments. The only reason I mentioned my ETs was to show that there is no need for any shifting and/or O/D button pressing to yield better 1/4 mile times, I tried several shift methods but I found if you leave it in drive with the O/D on it works best.

There's nothing special about the GXE over the SE. The only weight differences will be how you're car is optioned out. A 95 SE with no power moonroof, power seats, or ABS will weigh just as much as a 95 GXE. A moonroof adds about 20lbs, power seats ~8 lbs each, ABS ~10lbs, spoiler ~8 lbs. So you're looking at a difference of 54lbs between a fully loaded SE vs a barebones GXE. On a Maxima, 54 lbs won't really do anything in terms of performance. The 97-99s SEs came with slightly heavier rims which negatively affected performance, IMO.

that's what i was trying to say, but even the 16 alloys shouldnt make such a big difference.... sounds like you have some issues with your car bro
P.S. I wasn't insulting, if it came out that way... It's just that your car should be running faster.

not necessarily....... the 95 had a slight horsepower difference due to less emissions restrictions on the exhaust... That's it... otherwise the 95-99 is basically the same power wise.

I was running with a place racing cold air intake my max is a 99 gxe cali spec. How can i get better times without putting on more mods?

In my opinion I would just leave it in Drive and forget using the O/D button or any other shifting method because its an automatic.
You can modify your radiator fans to manualy operate to help cool your car in the staging lanes and after the run. Also before and after the run leave the heat on maximum blast to help draw heat away from the engine. Im guessing you must of been running on a hot and/or humid day cause your 1/4 mile times seem high, but with some practice and cooler weather I'll bet you can bring them down.
You can also take stuff out of your car to reduce static weight (IE spare tire, jacks, tools, any aftermarket amps and/or speakers), also race when you have a 1/4 of a tank of gas or less. Dropping the pressure on your front tires can be helpful too (usually 25 PSI), I dont recomend it for everyone because with my luck I'll forget to reinflate them on the ride home.
Well I hope this helps
Makes sense
i think i had this problem too from the roll (not sure) but o/d is meant to save gas while driving long distance highway miles and when you drive at high rpm's, if my memory serves me correctly, u burn gas faster which leads to more gas usage. Shifting at 4k puts the least usage of gas per gear and i guess that's why u don't shift high....

You really shouldn't turn the O/D on/off while moving above 10 mph, preferably not while moving at all.

98 GLE Auto - 44,000 miles. Original tranny. (not many miles though)
Both cars still run as strong as the day I bought them. I never heard of not switching the O/D off while driving. Wouldn't it be just like downshifting?

I'm not being cantankerous here, just wondering why? I've done this in every car I've owned for the last 13 years, with no problems. It seems like it's easier on the trans to shift it down than to labor it in traffic or small hills and such.
Just wondering?

I would really like to know if that is correct about NOT being a good idea to dis-engage O/D while moving...
