that's right... with only a catback and skill I pulled the below off. Many people here said that I would never do better than a 15.0 with my current set up... well here is your proof... I have ejj (from here, as my witness, he has a y-pipe, exhaust, and CAI and I beat him by reaction time etc, but he went on to run better times and killed me for the rest of the night...

sweeet!! Congrats man!!

Now next time to come to Toronto, you gotta give us a ride on the streets and show off your shifting skills!

We gotta make a trip to Cayuga!

Congrats! Very good. There is a 4th gen blk max that runs with no back seat and only an exhaust who ran a 14.8 too. Good run!

The back seat is no more than 5 lbs. What a waste of time =)

_DRU_

i wonder if my car can do that too.... nice job!

theblue

thanks guys! that track is excelent... and I'm going to get better, now time for a CAI...

TIME COMPLETED... let's party

primeevil711

great run, but I don't know many stock maxes with apexi cat backs.

theblue

if you have a stock maxima then put an apexi catback on (which everybody knows does next to nothing for performance..) = a stock maxima w/ an apexi catback

The back seat actual weighs 23 pounds. Probably still a waste of time though.

LoveSick

I actually took out my WHOLE backseat out and weight it. Including everything, it was more than 50pounds. Also, the guy probably took out spare tires, floormats and other stuff that made his car lighter than 50lb.....

A great save.

ejj

iTrader: (5)

How could it be 50lbs? Aren't you talking about just the foam and fabric?

I've taken that out, and I find 23lbs hard to believe ( although I know Don weighed it ).

That just seems high.

Oh, and all theBlue took out was his spare.

Dave B

That's some good driving!!!

Gotta disagree with this statement, though. A catback will give you more power. I saw a consistent .15 drop in et and a 1.5mph gain with just a b-pipe. The muffler isn't worth much, the B-pipe is. Last time I checked, stock means the way it came from the factory

What was the weather like when you raced? I assume that track is in New York? Now let's be honest. Is there anything else done to the car when you raced I'm talking about revising your intake, pulling out seats, running on fumes, etc. More power to you on improving your et, but improving on a 2.2 60 foot is gonna be really hard without drag radials. You can really see where the Y-pipe helps out my Max vs your car's catback only setup. Your 1/8th mphs are 73.6 vs my 75.2mph.

Are you shifting to 4th or just leaving it in 3rd.

Time for the Y-pipe


Dave

Here's some actual weights for stuff you can take off to race(I have them out at the moment so I just weighed them myself)

Front Pass. seat(non-power) 35 lbs.
rear seat bottom 12 lbs.
rear seat back 14 lbs.
spare tire 32 lbs.
spare tire cover 5 lbs.
trunk carpeting 6 lbs.
jack and lugwrench 5 lbs.

Total 109 lbs. = ~0.1 in the 1/4

theblue

Here are the minor left out details...

- yes, I took the spare tire out because it's easy to do
- 22 lbs in front toyo tires
- NOTHING done to intake... it was a cheap $5 one and it's been in my car for 3000 miles
- I was low on gas, but the empty light had not yet hit, I was running on sunoco 94 octane
- I rode that one to redline in 3rd as I crossed the line
- the apexi exhaust has been on for all my runs that I have ever done... My former best was a 15.2
- I pulled that vacuum thing so that my car would get max gas.. still don't know if that helped... maybe good for a 1/10
- weather was maybe in the high 50s low 60s (the weather sensor at the track was messed up so no accurate reading)
- nothing else that I can think of?

I plan to try for a 14.7 by means of a better final MPH... I still am not running as fast as i can on the top end, i want to try shifting at different RPMs to try to improve that.

I will put that warpspeed CAI on when it comes out... then I expect 14.69?

Dave B

What's the $5 intake?

Try shifting to 4th at an indicated 6000 (actually 5800 at the engine). When I did this, my ets improved.

I'm gonna try pulling the vacumn line and see what happens.

Keep racing before it gets hot out. I ran earlier this week and my ets sucked!!! I was getting 14.9s and got one 14.8. Once it gets above 70 and you've got to wait in line, that alumninum intake manifold heat soaks dramatically and it kills your ets. Believe me.

Get the Y-pipe. It will help you get off the line a lot quicker due to the added torque.


Dave

theblue

it was a cheap replacement filter (not an intake, my bad) maybe a proline or whatever pepboys sell... nothing special.

no y-pipe in my close future as i'm unemployed, but I do have enough to get a $150 intake... then that's it until I decide to go job hunting again.. i'm loving this full time student, no work thing...

Czar

I think the reason you got that great time is that you had an awesome launch. It is really hard to launch these maximas well(at least I can't seem to). I think my best 60'was 2.4 and you got a 2.2 right there you have 2 tenths and you are going faster out of the hole.
Dave, are you sure that shifting to 4th is gonna help? I am crossing the line at umm somewhere around 6300 in 3rd. I know that my power peak is lower, but I think that I would lose time trying to shift. What do you people that drag race a lot shift your maximas at? I have just been redlining it mostly at the track. Should I shift earlier?
I think if I can get to the track on a non crowded day and make a whole bunch of runs I can experiment with different shift points, launch techniques, tire pressure, etc.

capmaxima99

23lbs is true. I had to take out my seats to fix a raddle sound coming from the rear deck. I also weighed it and it was aprox. 23lbs. Does anyone one know how much time could be saved by taken out any given amount of weight? Such as taken out 100lbs of stuff in your car how much would you 1/4 time shorten by?

Chris

Dave B

Czar-

You've got the VE which makes power higher up in the rpms. The VQ looses power after 5800 while the VE makes power to about 6400. You'd be best served leaving it in 3rd the whole way.

Hey Congrats on your nice run.

iTrader: (1)

awesome run!! can't wait to see what you run if you eventually get a pipe and intake. Congrats bro. =)

theblue

thanks all! we'll find out in time.. I had a dream last night that I was the first maxima to run a 12 while still NA that one won't happen, but a 14.7 would be cool..

also, I just remember I forgot to tell you guys a funny little thing about the track... the idiot who was in charge of the water (for drag slick) kept trying to get me to line up with my rear tire 'cause he thought I was read wheel drive

Kenneth

iTrader: (8)

Is the vacum line mod safe? Tell us more,lol

theblue

I see no was it can hurt if you only use it at the track... my MPG went was down and I went through a lot of gas very fast... I also got my best time ever... once i am sure that I have reached my average 1/4 I will be able to better tell how some things work by testing... right now I'm only only 85% sure that I'm running as fast as I can

to the both of you, awesome times. i can only hope for such good times when i get to the track when it opens on june 8th (they are renovating the bleachers). to the person who asked... i read in some magazine, sport compact car i believe, that 100 lb reduction is good for about .08 seconds, so almost 1 tenth. so whats the word on optimum shift points (indicated on tach, not actual engine RPM). 1-2=redline, 2-3=6200 and 3-4=6000? opinions on whether 4th gens should finish a typical 1/4 mile run in 3rd or 4th.. ive been wondering this myself. since i can run 3rd to about 97 mph or so, but i know that the 4G loses power up that high, however you also lose time while you are making the shift. any opinions on the best method?

Neal

maxfreak_98

From what I've seen the only hope of us getting our cars to run below 15, is to have a 60' times of less than 2.3. Out of 15 runs over the past year, I've been only able to get below the 2.3 60's on four runs. All of the low end torque= bad wheel hp.

Great runs though....

100lbs for every tenth is a VERY general rule of thumb. It is directly related to how much torque the motor is producing. A Honda will drop more than .2 of a second with a reduction of 100lbs as shown by SCC. A Maxima might drop .1 of second and a 3600lb F-Body might only drop .05.


My shift points are entirely based on my dyno runs and gear ratios. The shift on the 1-2 occurs at 6500, 2-3 6300, and 3-4 at 6000. Shifting to 4th improved my et by over .1 and 1mph. Holding 3rd puts me right at 6600 rpms as I'm passing the timing boxes. Since the VQ makes absolutely no power past 5800rpms (regardless of NA mods), it is benefical to go ahead and bang 4th.

BTW, the tach is off by 200-300 rpms after 4500rpms in gears 2 and 3. I haven't tested the accuracy of 4th.


Dave

Dave B

I agree with Terry. It is gonna be very hard to hit 14s without hitting in the 2.2 range. I've hit about 4 14.9s with 2.30-2.32 60 foots, but I think that is pretty rare. IMO with the Maxima, for every .1 you shed off your 60 foot, you'll shed .2 at the far end. However, a 2.2 is about as good as you'll do on street tires unless you're racing on an incredible surface. A 2.1 is VERY HARD to come by. I could only wish for a 1.9. Hmmmm....a 14.1 sounds so nice

Really? I did it 4 times Friday night, even a 14.8. Being my first time out I don't think I did that well in the first 60 feet. Time after time I watched theblue get better launches than me. I just figured it was pratice and the lighter wheels he has ( I was still on my 17" Monsoons, he was on stock rims ).

http://www.rit.edu/~ejj5875/maxima/i....TimeSlips.htm

I also tried launching from 2-3k throughout the night, and I never really got a lot of spin, less than I expected. Maybe my tires/suspension can take a higher launch? Gotta try next time.

Kenneth

Cool! Which port did you remove? I think the Chilton manual page 4-30 has reversed VE and VQ diagrams for the vacum hoses though.

I just went and dug up the historical weather data for the New York area on April 28th. You guys had some pretty good weather that evening. The barometer was approaching 30.60 (very nice), humidity in the 40% range, and temps in the lower 50s. What's the elevation of that track? Is it at or below sea level? I've never heard of NYIRP.

As for hitting 14s with 2.3 60 foots, I dug up my old slips and I've hit 7 14.9s@93-94mph with 2.3 60 foots. I've been launching (ie dumping the clutch quickly) at 3000 rpms and I've been doing okay with upper 2.2 60s. I guess I could ride the clutch out, but I want to save my clutch.

According to the starter, somewhere between 1100 and 1300 feet...I don't if that's right though.

Are you sure? Coastal New York, is well, coastal (ie sea level).
