Hey guys, I removed my Injen intake and reinstalled the Oem midpipe flex section with the resonator and my Aem dry flow filter. The Injen intake was running out of air and just seem to accelerate hard then hit a flat spot about 2/3 down the 1/4 mile. So I figured the power was there in the lower portion of the powerband and maybe a shorter Intake would move the power upward toward the top of the powerband! Well it did that and more it just seems to accelerate really hard throughout the entire powerband now. The intake is virtually silent now and all you hear are those headers and exhaust! Next is a heat shield which will be fed by a ram air duct in the front grill area! Convergent style ram intake....

 

i hated my injen cold air...i conerted the injen to short ram by takin the elbow off(were it goes infront of the radiator) and it feels so much better i love it now...before it felt sluggish

 

I have an injen intake and have been wanting to try both of these ideas on my 01, but I have no idea where I should relocate my IAT sensor.

On the 02 and 03's, the IAT is built in with the MAF IIRC, so it doesnt need relocating; but on my 01 it sits on top of the second elbow by the radiator, right after the MAF.

Anyone have any ideas on how or where to properly relocate the IAT sensor on an 01, so I can try both these ideas listed above?

Thanks in advance for your time.

 

i went on eBay and bought a resistor and plugged it into my IAT sensor then zip tied it out of the way... also what this resistor does is fool your engines ECU into thinking its getting 60 degrees cold air all the time... i cant remember exactly what its called but i thought it was pretty nifty... never had a problem or a Check engine light either.... anyways good luck with your install. oh the resistor was like 5 or 6 bucks plus shipping

 

drill a hole in the pipe and install the sensor with a grommet

Yeah that's the first test I did when I was comparing the wideband readings between the entire Injen intake and it's upper section. The afr was dam near perfect in the short ram configuration but it's also seating in the rear of the that hot *** radiator!

 

Thanks for that, I may give it a shot.

 

Im trying to eliminate the long tube after the MAF, which is where the IAT currently sits.

Would it be safe to drill a hole in the elbow (after the TB and before the MAF), and place the IAT in that location?

 

What? No pics?

 

Scott, would you happen to know the approximate measurements of the ground wires you recently installed and/or all the grounding points (or a diagram of..) to where you installed them?

I'd surely appreciate it man.

 

http://forums.maxima.org/5th-generat...questions.html

Pictures with arrows pointing to where I grounded everything. I think the wires ranged from about 12" to about 24". Someone else put them together and I bought the kit from him.

 

Thank you.

I've had your thread saved for a bit now (which is very very helpful btw), but was hoping for an actual diagram from Nissan of the exact locations, if someone could provide it.

Guess im gonna have to dig around the car tomorrow for the exact measurements and locations to get an idea, but thank you anyways for your time and help to aide me along.

I'll be sure to post the exact measurements and locations when all is said and done.

(sorry for the temporary thread hijack, Cmax....moving on now )

 

Just buy a loooong run of shielded wire and connectors and cut to size.

 

i hate my injen intake.. i hate da fact da my max had so much power at take off.. now it only piks up at high speed.. im deflly converting it to a short ram next weekend

 

Well guys, I have an update on this I'd like to share. I took the long tube off my Injen intake and left just the elbow on, followed by the MAF, and then the filter; eliminating the long tube headed down into the radiator altogether.

Took the IAT out of the tubing and just reconnected it, and then zip tied it near the filter. According to the FSM, the IAT sensor is just for diagnosis and it plays no effect on how your car runs.

Well, long story short, all I have to say is WOW, I should've done this 2 years ago when I first got the intake. The powerband throughout pulls harder all the way through and is smooth as silk now. Before with the long tube connected, the car felt sluggish at times at certain points and I'd have to constantly be somewhat hard on the gas just to keep speed. No more of that now, as it feels like the car just wants to keep on going without being hard on the gas at all, which in turn should help my MPG in the long run as well. Also, the tranny seems to be shifting smoother now, and doesnt seem nearly as jerky when switching gears, which is a plus too.

Being an automatic, another big difference I noticed is that I hardly spin at all anymore when going WOT from a stop. Before I'd have so much spin off the line that I had to feather the gas pedal just to get a good hook on the tires. Now she hooks to perfection and takes off like a bat out hell, and doesnt seem to have any dead spots in the power band like it did with the long tube on. Hell, even when making a turn onto to a side street tonight and hitting WOT, the car chirped so hard into 2nd gear that it screeched the tires like I've never seen before, going into 2nd gear in an AUTO. Before it would just chirp 2nd a little every once in awhile, with just barely hearing a little peep. Honestly, I couldnt believe the difference it made with the power band and jumping off the line.

So Cmax, you were exactly right man about the power being there in the lower portion of the powerband and how a shorter Intake would move the power upward toward the middle and top of the powerband.

Thanks so much for creating this thread and giving me the inspiration to switch it up. And FWIW, the Injen intake BLOWS!! (atleast the long tube portion headed down to the radiator...)

If I have some extra time this week, I might even give your idea a try and see what comes of that. Thanks again man!

weak, i really wish i knew more about the injen before i got it. i keep hearing nothing but bad news about it. what i dont understand is the fact that injen claims that the intakes are "dyno proven". how can they claim that if so much is allegedly better?

 

Do you have to upgrade your exhaust if you add a intake? Thought about getting one because I keep hearing it helps your gas mileage, but I'd like to keep the exhaust quiet.

 

Nope.

Just stay away from Injen intakes though....

 

intakes have no effect on how your exhaust sounds, and the injen isn't loud at all

 

for our cars yes, injen does make some great intakes for other cars

 

I did this just now, yes it is midnight lol, and went for a test drive. My car isn't throwing any codes and it seems it picks up power/speed a little faster and smoother than it did with the long tube.... I am pleased with this setup for now and I think I should use some kind of air filter with velocity stacks for an even better improvement!

Does anyone know of such an air filter? I know cattman sells a jwt pop filter but I am not paying $140 for an air filter! lol

 

I not using my Injen Intake other than the MAF adapter and the AEM dry flow air filter. After searching my butt off thru all the threads regarding Berk intakes, JWT popchargers, and Oem midpipe. It was found that the Berk intake didn't really do anything as far as power increase but it did make plenty of noise and the factory midpipe made more power and was quieter (and free) for me. I might try a JWT popcharger on the end of my MAF from Cattman for $109. I'm not sure where you got $140...but I'm sure that the popcharger will help my Cattman headers by straightening out the intake charge with the velocity stack, but I'll see if there is a power difference between the AEM dry flow and the JWT popcharger. I really don't like oiled air filters...

 

109 + shipping = approx 140

I would really hope the pop charger makes a lot more power than a regular filter but I am skeptical to think so because how can one filter differ from another so much?

 

Its a little early but I just want to make clear. I could take the 2nd piece of my injen off of my 02 and just connect the filter to the next part and I have a short ram??

 

Yes.

 

And then would the short ram be more of a benefit than the CAI?

 

thats cool cuz I was just going to buy another one and sell this. Now that I'm outside looking at it, I feel dumb for not thinking of that.

Just did it. Hope the MAF is ok after this. I like the location of the other Short Ram's better but this one was easier.

 

I choice not to use the Injen upper portion with the MAF, adapter and filter cause it's sucking in more hot air than when it was down below the radiator shroud! My air filter is now behind the battery and I will be working on building a heat shield to reduce my intake air temp.!

 

so after reading this whole thread, can anyone tell me what kind of intake i can buy for my 02 max, which would result power increase and a nice sound. I obviously dont expect too much power from an intake

 

I can't choose for anyone else but myself! I suggest you run thru the older threads concerning WAI, Short Ram Intake, CAI, etc... here are my pic's for scottwax...

 

When your car is moving there is only a 2 or 3 degree difference in temp from the top and the bottom of the engine compartment. Someone (I forget who) here tested this and posted its results.

So IMO, all this hotter and colder air talk is irrelevant.

Lets see some Dyno results... one with the Injen and one with a short ram.

Until then... it just seems like bashing the Injen Intake is the "cool" thing to do around here. A "follow the herd" type of complex...

Yeah... I have one... ok. Maybe I'm a "homer" for Injen because of it, but I have no problem with its performance. Maybe I just don't know what I'm missing. I'll post a take off vid and you guys tell me.

Keep in mind its a humid 97* here in OK at the time.

 

C-young believe me I love my Injen intake quite alot...It's just to darn long for 1/4 mile running! It killed my trap times and speed. Your Vid was great! It seems you cut it right at that 3rd gear change where the flat spot is ...Anyways If you have your Oem reinstall it and check it out you'll see the difference it just keeps pulling hard no flat spot!!! I was trapping at 93-95 mph but cutting excellent 60' times 2.171 sec and .250 rt ( could improve)...

 

I see what youre saying... Yeah I cut it right at the 3rd gear because I saw a large, white car with blacked out tint coming the oppo direction. Usually thats what police look like. It ended up being one of those repo'd cop cars... I hate those! Excuse the iphone video quality as well. This was my first attempt at filming anything with it.

So for every day driving around town an Injen is good in your opinion? I'm not up on all the drag game so I dont really know what youre referring to above with trapping.

So clear this up for me... for short, quick bursts (0-60) an Injen is ok in your opinion? Or is it the opposite? Because I don't drive around town at 80mph much... I just like blowing these sh***y Neons with huge wings, potato gun mufflers, and ugly body kits off the line at a stoplight.

 

CMax-thanks for the pics. Right now I have the GAB mod, but as inexpensive as cone filters are, it might be worth trying one to see how my car responds.

 

Yes, The Injen is a really nice intake it is great for cruizin and haulin ***, I just had a hard time reducing my 1/4 mile trap times and increasing the trap speed! The trap is at the end of the 1/8 or 1/4 mile and is the instrument used to stop the clocks for you elasped time. I double wrapped my with exhaust wrap and installed a heat shield sleeve! It seemed to really work well no heat soak from the radiator fans! The only problem I was having was the long tube (Good for low + midrange power) not for higher rpm power...Get it?

 

Scott you'll need to get a MAF adapter which are on Ebay for just under $7...

 

thanks!

 

GAB is already the best compromise, don't bother switching to short ram. After the ECU adapts all auto trannys will feel significant drop in low end pull.

 

Any stock A/T Maxima might feel weak at the bottom end, But with all the bolt-ons installed on mine (I/H/E/P/S/MM) I'm still able to fry the tires at a 20-30mph roll!!!!

 

intake/headers/exhaust/p???/s???/motor mounts . . .

whats the p and s ? lol

profit???

 

Intake+Cattman Headers+Wsp Metallic Cat+Cattman Cb+Ur UDP(P)+Illuminas w/Progress springs(S)+ES motor mounts+grd kit+etc

There's the P + S...I might need a 3" Catback system as well!!!
