i just installed the injen cai on my 2k2 3.5 and instead of running 14.4s im running 14.7s at best...in the same conditions...i also feel a lag off the line...and the tires dont break out like they used to...am i missing something?...help me out please...

Is this anything new? Let me guess what the next thing will be, SES light on?

Is it possible that you can't expect any gains with an intake only?

MaximusLow-- I have an idea... reinstall your stock intake.

Try to get your money from Injen/ Shop and show the time slip for proof that you lost power.

I am not surprised, the injen sits close to the radiator. Sell it and get a berk

Did you reset the ECU after you installed it?

You need Place Racing style CAI for true CAI.

Not that hard to answer your question. If you lost power, go back to stock.

MaximusLow

hahaha...i just find it funny that i spent 200 some odd dollars on a power adder and lost power...way ta go injen...thanx guys...Caspers goin back to stock...

Put your stock resonator back in and run a filter with it.

scopium

besides Place racing intakes..
short ram intakes works best on fifth gen (i.e Berk intakes)

† ErV †

take off the intake.. they lose you power, not gain. but people refuse to accept that.

ihavea5spd

an injen warm-air intake is a sound mod, not a performance mod. you are
sacrificing horsepower for that cool sound.

I doubt you lost power. Usually you lose alittle low end torque, not power. With intakes it stretchs the power band and your overall gain in power and torque. Also how long was the car running????? I know with my car when it cold it fast, and when it running normal temp it alittle slower. You should also reset the ecu.!!!!!!!!!!!!!!!!!!

BTW you don't have a check engine light on, do ya??????????

MaximusLow

nope..no check engine light nothing...i did reset the ecu...i disconnected the batt. terminal for like 10 mins then idled my car for another 10 then did some normal driving for another 10...till this day nothin...i deffinately lost torque...before if i floored it my tires would just break out and smoke...now its a few chirps and im goin it feels like its lagging a little and then at like 4500 it starts pullin better...im deffinately returning it..i hope nopi takes it back...ANYONE WANT TO BUY AN INJEN CAI???? lol let me know...

IIRC, that's not the correct procedure for resetting the ECU on 3.5 Maxes.

joebangaa

iTrader: (3)

lol i hope you reset it cuz i was about to buy one

spirilis

iTrader: (2)

yeah, you did NOT reset your ECU. 2002+ (VQ35DE) uses a different procedure for resetting the ECU, and it does not involve disconnecting the battery.

What do you do when you get the SES light? That's what I have now. I installed the Injen a week ago though.

Here's a good opportunity for me to prove a point. The best is not always the most expensive out there.

I'll send out one of our parts to you for free, it'll basically convert your injen to our setup (Berk Technology). You'll use the same Injen filter so we will be keeping everything constant.

Go back to the track, let everyone know what time you get now.

Contact me for details.

i keep saying that Injen sucks but no one wants to believe me.
what the hell do i know?

deezo

iTrader: (3)

...and people keep trying to market Berk intakes like they give you horsepower. I've learned a while ago that intakes are only for looks.

Daily Driver2k2

He didn't lose anything, his powerband shifted.Also his ecu like any mod added to the 5th generation has to learn it. Even when i added my Injen, it took about a week before my car felt "semi-normal" again after resetting my ECU.Also adding a cat-back system helps reduce that"loss" of power feeling, with it you gain alot of your low end back.One thing i notice when i had my Injen , before i added my cat-back system, my mid to high end was definitely noticable.

My solution to you is to reset the ECU and get a cat-back system , 2.25"-2.50 set up ,anything over that diameter and you will be creating a top end monster , but you will have no low end grunt to take off.

try a stillen intake.. cant go wrong with them

ripper

Did your trap speeds change at all? Are you auto or MT? If 6MT, you will want to launch at a slightly higher rpm. That should get you back some torque off the line.

kcowden

iTrader: (2)

I agree, reset the ECU with the Technosquare procedures, get yourself a Y and B pipe and you should see some results. These damn computers on cars nowadays really screw up any mods to our cars. I had an Injen w/ a Y & B pipe along with a straight pipe and my car drove like a bat out of hell. Went back to stock intake because my wife drives the car and doesn't appreciate the fine art of modding.

I also have the injen and am willing to test this out...can I jump on this too?

MannyNJ2k2max

iTrader: (3)

I doubt you lost power.....your gains are probably on a diff rpm range now- besides 4-5hp is all we are talkin' here...dyno and see where your power band picked up, make launching/shifting adjustments

MDeezy

iTrader: (27)

Injen CAI's are suppost to improve your low end but sacrafice some of your top end (unless I have it backwards).

Also the ECU needs about 200 miles the run throuhg its normal cycle to learn your new Mod to the car and its performance, so it should start to feel somewhat right after about 200 miles.

spirilis

iTrader: (2)

You have it backwards, yes.

Most if not all aftermarket intakes utilize larger piping which tunes the intake for higher-RPM performance at the expense of low-end (due to it being more efficient with higher airflow volumes experienced at high RPM vs. low RPM)

deezo

iTrader: (3)

Yeah, it shifted and he LOSS HP in the lower rpms.

Daily Driver2k2

Its a shame Injen didn't design the intake pipes slightly smaller in diameter,that would net a better balance in Trq/HP gains. The pipe sizing is to large to gain any real TRQ gains, the same applies when you use to larger of a cat -back system, everybody wants the 3"+ sizing exhaust, but what they fail to realize there not pushing a turbo or SC where 3"+ sizing is needed. For our N/A engines 2.25-2.75 is MAX! Anything higher and your car will be making top end power which is useless for daily driving needs, now track racing , thats a diffrent story.

I had an idea that I'd love to try sometime with my Place Racing CAI. I wonder if it'd be possible to build a rubber hose adapter between the midpipe and the MAF sensor, or even the MAF to cold-air tube that contracted to a 2" opening in the center but remained 3" on either end, so that it added a deliberate restriction. A rubber hose like that would have to be custom built, or maybe some rubber glued to the inside of the metal tube could substitute.

spirilis

iTrader: (2)

Actually, I could test this out safely by lining the inside of the MAF adapter plate tube with stick-on weatherstripping that I have. The MAF adapter would be the perfect location because of the MAF sensor's screen, which would disallow the weatherstripping from going further into the throttle/intake manifold in the event that the glue unstuck.

† ErV †

You earn a retarded post of the day award, if we had such.

MaximusLow

ok i THOUGHT i reset the ecu...switched the ignition to "ON" pressed gas 5 times it started blinking that whole deal...but how do i really KNOW the my ecu IS in fact reset.???

spirilis

iTrader: (2)

The only true way is to get an OBD-II scantool which can read sensor values, and check to make sure the Long Term Fuel Trim values for both banks are reset to 0.0%

MaximusLow

you think autozone could do it for me?...

MaximaPolak

iTrader: (9)

Well....with cold air intakes you loose low end power but gain in the top end....

Great for highway racing, bad for 1/4 mile racing.
