ya, the plugs should be okay. I only have 120xxx KMS (80ish miles?)....
Well, if the cats are messed I will fix that with headers/catback... throttle is DBW so how do I check that? I was going to ground the knock sensor too, u think that will help?

 

You need to concentrate on your 60' times! I'm an 03 A/T, and my 60' is down to 2.171 sec, with the help of Illuminas, Progress Springs, 18" light wheels w/ 245/40/18.... but I was running a Injen Intake and it's intake tract was too long for moving more air as fast as I needed too @ the topend. Switched intake setup (Shortram) to match headers airflow at higher upper range in order to increase trapspeed in the 1/4 mile!

 

mmmhhhmmmm yes I know I need a short ram. Do you guys know if I can use the adapter and filter from my injen and run it straight off the maf and on the intake with no extra pieces?

Rims/tires/suspension is all too expensive since I just ordered the H/E.... good to know, I was wondering how much of a difference suspension would make. I guess it should be a decent helper to be lower to the ground and stiffer susp should help the launch right?

 

you should be alble to, reason why suspension helps is because with your car closer to the center of gravity and springs are a bit stiffer your car would n't have as much lift as the stock springs causing less hood lift hence a tad less spin off the line

 

IIRC, nzelinsky is 3400+ feet above sea level.

His corrected times for his 2nd time at the track came out to be 15.24 and 15.44, which seems about right for his second time at the track with a 3.5 auto.

 

Yes you can.

Just did this about 2 or 3 weeks ago.

 

can I get a pic?

 

Here is one example:

 

yea it should be the exact same procedure as installing your cold air, just without the second part

 

Do the DR mod, it shaved a .1 and added 2mph on my trap, and work on your launch, thats key to gettin lower ets. Forget about shifting let the automagic do its work. Your best bet is to try different lanuches, I usually trans brake to 1800 and mash it but spin alot, if I don't trans brake and slightly mash it till it grabs I get about the same 60'. So I think with more practice I can get better 60' without trans braking, but on the other hand the consistency of my et with the trans brake amazing (less than .05-.1). If you're goin for PBs try it w/o, if you want consistent ets trans brake. Practice is key and finds what works best with your mods.

 

what is transbrake? just holding the footbreak and gas sametime?
also, what is ets and pbs?

ya its hard to practice because there are no good roads for me to get that kind of speed legally... also the track is much more smooth than the pavement up here so its like a whole different thing with the loss of grip that I am used to. With my winter tires the track is like ice on my launch.....

Im thinking about buying some cheap 16" or so steel rims and putting some slicks or at least drag radials on just the font to pick up my 60' time. anybody know if 15or16" standard steel rims will clear the breaks on a 5.5? or what tires would be good to use, not too expensive?

 

 

Wow but Ok ET= elapsed 1/4 m time and PB= personal best. You've got the transbrake right, one foot on the gas and one on the brake . Don't bother practicing anywhere but at the track because you won't have any real data to compare to. Practice at the track record your launch RPMs on your time slips to help you figure out what works best. Try different things to see what yeilds the best 60' which should give you your best ET, but ONLY at the track w/ timing equipment cuz your butt dyno will never be as accurate as track equipment. One other thing I'll add is you want to limit tire spin as much as possible, you just want a slight chirp then traction. This you can practice at any stop, just see how much you can drop the gas before it starts spinning. Remember just a chirp then feather the gas without spinning to WOT (wide open throtle). Also remember when you get to the track you should be able to get on it a little harder w/o spinning due to the track prep vs normal street conditions. Hope this helps clear things up for you

 

i never use the DR mod, it probebly does help, but im not willing to give a tranny for .1 it makes me nervous on every shift

 

Thanks man! Im gonna be chirping off every green light now to work on no spinning it... hope I dont get pulled over!

 

good info..

 

The dr mod actually will prolong the life of the tranny. The faster it shifts the better. Its not something you want to do under normal driving however...Only wot like at the track.

 

it just makes me very nervous

 

What you really mean is powerbrake not transbrake! Transbrake is a component not a procedure...I would bring it down to around 1500-1600 rpm so you don't spin excessively but on the edge between max traction and tires about to loss traction!
As for using the upper half of your Injen intake yes, you can! I just use the Oem resonated midpipe, Maf, and adapter with the AEM filter ( the pics above @ reply # 10 are mine) I'm an ex-Injen user!

 

thanks man! Im going to try that probably next weekend. I think I will order JWT filter for it since the injen is pretty small

 

I won't order anything yet! That injen supplied filter is really pretty good! I would set it up with the Oem midpipe, MAF and adapter w/ filter and keep on trucking!!!!

 

I'd go with the AEM dryflo filter, the injen is definatly a good filter but I'd be nervous running an oiled filter that close to the maf. The AEM filter (Part#: 21-203DK) is quite large, much bigger than the injen.

 

I dont think the injen is an oiled filter... It was dry when I got it, never oiled it so...

AEM is okay but isnt the JWT sorta the best one?

 

what was your track elevation? Stock you should be around 94MPH through the 1/4 mile

 

1+Mile

 

Your over 3400ft elevation? I noticed that on your other thread.

Now I understand why your times are in the low 16's with traps around 87MPH

I run at 3075ft so i am familiar with what you are going through! I want a sea level run to see what the car can do!

 

Maxus10!!! I'll be running there and will have headers and exhaust on in the next month. If Im lucky Ill have my suspension upgrades and a zex75 shot by then too. If your not coming I will have my wife film the runs to put on video. I have a thread called "my second time at the track" in the 5th gen section with a vid of a couple runs.

 

Sorry guys, but lets hope they actually do some kinda track event at maxus10... but being on the nissan forums for them nyc dudes, seems like that might be the whole 3 day event lol

 

u mean drag racing for the whole thing?? that would be awesome, thats all I want to do. OR are you saying they may not be doing it at all?? b/c that would not be cool/not worth driving down for me if I cant race some other maximas.

 

It is! It's oiled straight out of the box for the manufacture!

 

Really? My injen filter was a dry filter. I did however just replace it with a K&N filter which is oiled.
