I'm not exactly sure where this Injen CAI is getting more gains than the Pop Charger thing is coming from but as first350 posted and I posted earlier in this thread, CAI have been known to lose power. I wouldn't go with a CAI, I would use it as a SR if anything but to me it would seem like a waste of money.

Thats a link to first350's thread.

 

+1 REVUPS hate spacers, unless you slap on a 287 or MREV2 with a spacer.

 

Saying CAI loose power is a genralization. Some CAI loose power, some do not.

 

well for the difference on my 03 i think the best price/performace/ease of installation ratio would JWT and MD 5/16 spacer.

 

jwt makes no power... 1-3whp maybe adn ZERO whp on the butt dyno...03-06 makes no difference... those things just loook nice and give the engine a nice sound but neither will do anything as far as gains...
so price/performace/ease of installation ratio ..the injen is still decently priced compared to other n/a mods, performance is better than jwt specially on 03-05 models... ease, ovbiously not as easy as the 15-min install the jwt takes, but stil very easy DIY install

 

So how would an Injen make more power than the JWT if someone gained 3MPH in there trap by eliminating the "cold air" part of it? Without the extension, I don't see how its any different than the JWT.

 

you cant compare a dyno chart that clearly shows the powerband gains power and in the injen it does show it gains more than jwt. Youa re talking about track times and speeds, well there is way more to it as to why that person gained the 3mph trap time or he loss his trap time in some other case. I can rase 5 times that day and increase my trap times each time or loose in some...
the funny thin is where the injen cai shows the most gains is in the top end



THe injen can be made a short ram if you are scared when its raining to hydrolock the car where the jwt will always stay there sucking all that hot engine air.


ok some charts here, the setup is injen exhaust testpipes and the old RD injen CAI
https://my350z.com/forum/attachment....7&d=1120701096

this is the same setup but with the newer INJEN CAI
https://my350z.com/forum/attachment....8&d=1120701096

this was done on the same dyno with in 2 days apart, now its not easy to compare #s since the weather conditions were quit different both days but it still shows from one CAi model to the next

and i think the jwt is only comparable to the rd version maybe....

NOw if the guy plans to save money and go with the jwt then i can't argue with that.. 120 bucks is super cheap..even cheaper thana Y pipe

 

If you read the thread, you would have seen others that had the same issue. It was actually someone else telling him to take the extension off and give it a shot.

If that were the case we could argue about my timeslips. I ran a 14.1@99 my very first time at the track which was warm and humid. I added the Pop Charger and ran 13.9@103 at the track on a cool, dry night. So do I treat this as a "stock" time, or did the JWT actually help, or did the conditions of the night give me a 4MPH increase my trap speed?

I HIGHLY doubt it was just a coincidence for first350, especially when other people chimed in and said they had the same issue.

 

hard to judge unless you to basline before and after dynos of a jwt vs injen the same day and do 4 1/4 laps that SAME day as well

otherwise its all up in the air,...
i am going based on dyno numbers which have a lil more consistensy than how a driver takes it on the track each time in different days

 

i do the mods more for fun then huge gains... I mean i dont want ot do something that will decease performance, but, I'm notlokng ot spend alot of money, and i'm not worried about huge gains... I bought this car cause it already has close to 300 hp.
thanks for all the imput though guys

 

Hey IIQuickSilverII, my buddy had a JWT, went to the dyno and got some decent numbers, had a change of heart, went with the Injen CAI setup and actually showed 3whp less.

 

not a good example
you just pointed he went on a different day different weather conditions... and even if it was the same dyno and same correction it doesn't mean squad unless he had dynoed both setup that same day on the same dyno.
When i dynoed my injen cai a friend was next and got way lower numbers, but i am not bringin that up cause its different cars and not all react the same

 

lol

Injen CAI > *

 

this isn;t supposed to be an injen vs other intake systems.

 

So what did you order?

 

Good question. I have an MREV2 and spacer that should be here Saturday.

Ended up getting an Injen CAI really cheap to experiment with using it as a short ram.

 

i got the nismo intake right now and i really don't feel and power gain or loss, all i know is it sounds great when im @ 4000 rpm +, i plan on getting the iso spacer as soon as i find a good deal on it though, but from what i have read, the spacer is one of the "best bang for the buck" mod for the z

 

yeah. I have limited cash flow right now. I just purchase some Tien S springs and some 20 and 25 mm spacers.
And i have my eye on a set of 18inch G35 wheels. I think I'll be happy with all of those together.

I still plan on purchasing the JWT and the Iso spacer.

 

Hi,
IMO, get the MD spacer and Pop charger.
Partshipper Dave will hook you up.

Good luck with your choice!

You kill me! lmfao.. you must have an injen CAI.
