RD Series Race Division Intake Systems: Murano 3.5L

he RD series is a cold air intake system for the enthusiast craving mid-range power. The intake tube is strategically placed behind the front bumper to acquire colder, denser air. Although most of the RD series is a one-piece design, several are two-piece designs due to the mass air flow meters. Every RD system is certified or pending by the California Air Resource Board and backed by Injen Technology's limited lifetime warranty.

A. 6061 Aluminum Alloy
B. Rubber vibra-mount used to relieve stress due to engine torque.
C. Injen silicon straight hose connections with stainless steel clamps.
D. Injen's specialty purpose silicone hose
E. Tig welded bracketry and rubber vibra-mount for extra support.
F. Tig welded vacuum ports.
G. Injen's urethane Air Filter with built in velocity stack

THESE make an AWESOME sound on the G coupe, and are VERY well made... i have no experience with them personally (nor will i, since i decided to go F/I instead), but know several that really like these intakes....
found this item HERE while ordering my new clutch.....
happy Mo'ing!

Ah thanks.
I emailed Injen and asked for dyno results for a Murano as they seemed to have other cars they have a product for.
We'll see what happens. |

I remember from years ago, that longer intakes gave better low end torque but at the expense of high rpm power.
Anyone hear of this or noted the difference on a dyno when installing one of these things? (I don't consider your behind and the sound to your ears a dyno, although they're often fun measures...):D |

| The intakes that involve a pipe as well as a filter are sometimes tuned. A wave is created in the intake when the intake valves close, and the air bounces off the valves back out the intake. The wave travels to the filter, and then bounces back. At whatever RPM the intake is tuned for, the wave will be returning to the intake valves just as they are opening, allow a bit more air to be crammed into the cylinder. |

i searched some and found some pics of the INJEN setup on the g35 (VQ35DE)
id add the bypass valve it it also, to help prevent moisture from going thru the pipe (for the sake of the MAF mostly)

SMS - thanks for staying involved with us after your Murano's departure. :)
Do you have the SC installed on the G35 yet? What are your overall impressions? I gotta see if I need to be cautious of some of these G35s. |

Looking at image: http://g35driver.com/forums/attatch...81-Injen-01.jpg
I am wondering two things (for now)
1) does the CAI simply slide down there or do you have to start pulling things apart like say replacing the fog lamp bulbs.
I would like to put on and if I had to restore OEM equipment if need be in under an hour.
2) Water, any concern sitting that low? |

Here is the dyno results of the Injen CAI on a Murano:
I'm no expert reading this but to me it looks like a nice power increase between 3.5 - 5K RPMS. |
|
|
| esemes |
wow
id say thas almost too good to be true....
but id sure like to find out!!!
((interesting how the tranny affects the hp/tq curves))
so, who's up first??
((and what happened to my stars??)) I dont think i ever had any??:( |
|
|
| dmako |
They responded very quickly to my request asnd want to pop in on this discussion. I replied with the link.
I also asked for instalation instructions, and how they would answer the water getting intothe CAI as I know it will be asked. |
|
|
| esemes |
dmako--
the water IS an issue, as the airbox is eliminated, and the filter relocated lower (and more frontal to avoid getting as much hot air/vapor as posible..)
i know (for the G) they have two versions, onc which locates the filter (as i showed before), and a shorter version, which transofrms the long one (easily) and puts the filter up higher (albeit less effective)
if you go offroad, id say avoid the long one altogether......
if you stay onroad, id think about the long version, as even a standing puddle shouldnt get sucked in and cause hydrolock.... you'd need to drive the car into several feet of water.....
my opinions only, of course (and assuming they offer the two versions for the MO)

Am I reading this thing right?
about 171 HP at the FW stock?
And it is rated at ? 240?
69 HP drivetrain loss?
That's WAY too much.
That would be 40% loss?????
I must be looking at it wrong.
Help me here, sms.

for the fx CAI they developed, they used an awd model. actually, they searched out an awd model for some reason.....
im thinking the same must apply to this (its an awd version, and , sit down, like the fx, experiences nearly 28% loss)
somewhere i have a fx35awd dyno showing the identical drivetrain losses.... |

| As far as water goes, the engine won't suck up water unless the filter is completely submerged in water. Even if it is half submerged it should suck air through the other half before it sucks water because air is lighter. Of course, if you stomp on the throttle during half submersion, then some water may get in there. I had one on my old car and it was lowered. Whenever I had a doubt, I would just coast through in neutral, or with the clutch pushed in to drop the RPM's. With the Murano being as high as it sits, you would have to drive through some serious water. Most likely, a splash shield will have to be cut to get the filter locates to the right spot. They usually run the filter to the corner of the bumper, just in front of the wheel splash shield. |

Gotta be sceptical of that dyno plot injen posted. ~25 ft lb gain at 3500 RPM???
Anyways, don't sweat the drivetrain loss. Wheel dynos are a very inexact science and the inexactness is greatly amplified when you move the an AWD dyno. The usefulness of the plots is to compare the effects of modificiations an a particular car, not the absolute numbers relative to other people's claims (unless you want bragging right for internet forums I guess). |

well stated halo... but you will find alot of loss (and added weight) with the almighty skyline-derived system..... its part of the reason that the Jpn gt's switched from awd to rwd last year, i think....
dynos are like bathroom scales.... (best way of looking at it, imo), but the mustang dynois arer by far superior in their ablility to measure actual hp, and as you stated, changes in hp.. |
|
|
| Halo |
True. I don't quite understand the move to RWD in the JGT - didn't the AWD skyline eat the competition?
On that note, I really want to see this in December:
http://www.jgtcusa.net/home.html No S2000s of course, but that isn't really Honda's GT platform I guess. One Imprezza though. |

I think it was just a passing of the torch; the VD (ro VE??) series block did devour everything in its path.....
the move to the VERY strong n/a VQ was to compliment the nissan marketplace, and its implementation of the VQ in the modern market vechicles.....
heres a how-to on the injen CAI, as authored on the Z-CHICKS website::

How to, I asked and Injen said that they would reply with installation instructions for the MO.

Scott and David, thanks for contacting me!
Hi guys, I'm Duy the Injen Technology Rep. First off, thank you guys for the interest in our great product, I am sure you will be more than happy with it.
Just a note to those who aren't familiar with reading dyno charts, you should view it in regards to the complete powerband. The red indicates tested while the blue is baseline. In the chart that I sent Dmako, you can see in the powerband that our intake system has notable gains throughout the whole band. We were very pleased with these results!
I've also sent Dmako, the installation instructions as well as it is pretty straight forward...Most of the time spent will be removing the stock pieces :) (Dmako, I still need to get you page 2,3- sorry for the delay).
If you have any questions, feel free to drop me a line at duy@injen.com and I look forward to helping out anyway I can!
Cheers
*SoCal FX45 Owners Please contact me! Looking for test car!* |

Okay, we've had a few folks inquire on how to increase the HP on a Murano.
This seems to be a viable solution, increase air intake, step #1, exhaust #2. These would IMO produce a nice amout of extra HP without going too far as to affect the CVT.
Any takers (before me) :D |
|

| Eric L. |
| I would like to see install pics before considering this option. |
|
|
| dmako |
They 'should' be coming. I asked for instructions but only received page 1. Very basic i.e. disconnect batt.
Their scanner went down and they will send when back up.
PS: I think I heard that at full throttle the CAI will drown out rattles. :D |
