what do think boys ?? injen , element114

[Mishooo]

Hi every body

I read many topics in the forum that's the injen intake is making loss in power if you install it & install exhaust such as element114 ... etc without tuning the ecu

So my freinds what about the Element114 CAI with the Element114 exhaust ??

I remember that some member here in NICO install it but we don't see any reviews

another qwestion , as you see the M45 after 160 km/h it's DIE

and struggle to reach 200km/h in this video

do you think if I install only a CAI it's gonna make some difference at high speed ??

wait for your opinions

In that video it just reached its limit. It was almost at redline in 5th. Thats all it had.

I know that it's reached the limit

but I notice that from 160 km/h to 200 km/h it's struggle to reach 200 km/h

LOL a CAI and exhaust isn't really going to be all that noticable at that speed. I definitely do not recomend the Injen intake because of the intake pipe size variance from the stock size. Injen claims MR technology to maintain air fuel ratio - which really means that they altered the size of the intake pipe to trick the ecu. That technique is garbage and should never be employed on any nissan. It works by itself, but add an exhaust and you just trashed your A/F ratio and lost a ton of power.

Only real way to make the 100mph(160kph) - 125mph(~200kph) noticably faster is to add boost. Remote mount twin T3 turbo's intercooled with an uprev tuned ecu making 500ish hp will make the 100mph - 150mph seem the same as stock 30mph - 80mph

what I want is to reach from 0 to 200 km/h in less than 20 seconds " 19 is good "

the car accelerates from 0 to 160 is excelant but after that it die " when you shift to gear 4 "

so i want to install a CAI to make the car accelerate better after 160 km/h

the injen you don't recommende it , so what about the secret weapon intake or the element114 intake is it also make loss in power " if I install it alone ??

Take Ken and myself's advice. We already know what works and what does not. The Infiniti ECU's are very sensitive and picky. Just add a Stillen or Megan full cat-back system and be done with your mods. The Stillen system is what I would recommend since they put time in creating that exhaust system to make the 4.5L engine produce more power. Also, they did not only create a one exhaust system fits all either. They tested the M35 and M45 and noticed that they needed different type mufflers to compliment the two different engines. I don't know of any other exhaust manufacturer that has put this kind of R&D into their exhaust systems for the M cars. Yeah, I have the Element114 kit on my M45, but I don't recommend it.It sounds good, but the fit and finish is very poor. I had to have an exhaust shop cut it in a few spots to straighten it out. Don't do the CAI kit as it will only decrease power. You will only be buying CAI kit that makes noise under the hood.

Do the items we recommend and you will not be disappointed.

Good luck and hope you listen to us.

Well I just went back and wathced the video again and from what I gathered it took that car ~24seconds to reach 200kpm(123ish mph)

I go back to my earlier statement and recomend boost. I don't think that there is any way an exhaust/intake combo will put you to where you want to be under 19seconds.

That being said I'll go out and test this today and see how fast my M is to 125mph and report back.

Oh, and using a translator reading the coments for that video, that M is 100% stock.

Can you add a Video clip for your acceleration plz

from rest to 200 km/h

my M45 reach 200 in a 21.9 Seconds " stock "

Sorry, I stayed in town last night so I couldn't get any runs in. Will try today and get video.

OK

any mods on your M ?

Ken has done the throttle body bypass mod, a custom CAI kit, and a fabricated exhaust system.He is supposedly going to have UpRev do the transmission valve body mod and a custom chassis dyno tune.Not really sure if he had them do this yet. I would have thought this would have been done by now, but I have not seen him post about it.His intake and exhaust mods were both done personally by him. You cannot buy these mods. Wait until Ken posts back with more detailed info on what I'm talking about.

Is it a rule of thumb to add either exhaust or CAI, but NEVER together as it would only result in loss of power?Also what is the typical gain in terms of HP from Stillen cat-back for example? What about from CAI only (w/o exhaust)?

[ken in az]

Didn't get to do it yesterday either - life keeps getting in they way of my modding - lol I have to go about 25mi outside of town to do these tests as I don't feel comfortable doing anything over 100mph any where near close to town. I also want to get on a level road. Something I didn't notice before, but you never see what kind of road he's on in that video. He could be struggling up top because he's going up hill, or he's going down hill to start. Tough to judge that video to real life unless you have a common test road.

Timing his run, he's at 13.9 to 100mph which is close to a 1/4mi looking at his odometer, for a stock car that weighs 4000lbs + 150lb driver = 4150lbs. Plug that into a horsepower calculator and it gives a lot higher power number than stock so something must be up.

I'm going to start a new thread because I found something to be fishy with my car and the rear axle ratio.

and yes M4T5 is right, I have a home made intake that now has a heat shield that directs the factory cool air duct to the filter, removed secondary cats and y-pipe and replaced with 2.5" pipe with an X-pipe and 2.5"pipe to the stock resonators and stock mufflers. TB coolant bypass mod as well.

And yes, sorry the transmission shift kit hasn't been installed yet, life has been busy for me....maybe this weekend??? and UpRev is adding the live tuning to my ECU ROM file as we speak so hopefully that'll be ready soon also. Sorry for not modding my car fast enough j/k

I say just don't add the Injen because it is junk....my homeade adds a high flow amsoil nano dry filter and retains the factory MAF sensor piping diameter to keep the calibration the same. The negative about my homemade intake is that it draws in hot underhood temps, which is really only a problem when in traffic or parked in line at the drags that's why I want to add a heat shield otherwise highway speeds the stock cool air duct over the radiator cools things off pretty well.

This post kind of sucks for me. i stumbled literally a day after i instaled the Injen on my M. Any suggestions should I remove and try to find some other sucker that wants. i really have no intentions on installing any after market exhaust any time soon.

[M4T5]

throw it in the trash or just send it to me! I'll pay for the shipping to get it off of your hands.Let me know something.

If you have it on there by itself, then just leave it. From what everyone says it works well by itself but looses power when you add an exhaust. so if you aren't adding an exhaust, just leave it on there as it should work just fine.

M4T5 - I thought you got the Element 114 intake - no? I remember you having a fitment issue with it, did it get worked out or did it get filed in the circular file?
