Just curious to know what intakes you are all running with your aftermarket plenums and why

 

Kinetix/Popcharger - horsepower/dollar

 

kinetix/k&n typhoon - just horsepower

 

Kinetix/popcharger... sounds awesome, power is there... wouldn't have it any other way.

 

Crawford ver. 5/ Nismo CAI......I was willing to pay more for quality.

 

Kinetix / OEM Air Intake with K&N. Hopefully will install Kinetix Cats this week, then dyno. After dyno, JWT Pop Charger.

 

Crawford Original (Soon to be V5)/K&N Drop in.

 

Crawford - Powdercoated Injen tube, JWT pop charger - this combo made lots of power on my car.

 

Dynoed with my old AEM and original Crawford plenum-dyno showed no power, so now I have the pop-charger because nobody has lost power with it, unlike some with the AEM. Going back to redyno-if I dont make more power then Ill be getting rid of the plenum.

 

Hi there - please post about your dyno results. I have note done any intake mods to my car yet and am very interested to see what your combo yields.

Thanks in advance.

Looks like the popcharger is a popular choice for those with aftermarket manifolds. I am considering either this or just sticking with the stock air box and using a K&N drop in.

Thanks for your input guys.

 

I'm currently running the KINETIX V2 Plenum and a K&N Drop-in filter. From what I've read and been told, the OEM Airbox is VERY well designed and you "might" get another 1 or 2 hp by going to CAI or popcharger and personally a couple extra horses doesn't justify the price. Stick with the Stock airbox and just throw in a K&N and you'll be fine.

Crawford v5, "Z" tube, and POPCharger.

When are you going to redyno? Looking forward to hearing your results.

 

AEM only since I got that shortly after getting the car.

 

Plenum and stock airbox...

No reason to go with anything else but the original...

 

I've seen a few cases for stock airboxes, and looking at the stock airbox it does indeed look like a nice design with a straight tract.

But the question is, why are so many CAI intakes for sale and have dynos with 5+ HP (over the nice stock intake) to back up their claims?

Why wouldn't the same benefits of a CAI (i.e. conical filter for more intake surface area, lower placement for colder air) also be synergistic with an aftermarket plenum?

Now, if the difference were truly only 2-3 HP (CAI vs. a stock airbox with K&N filer), then there's no way to justify the cost.

Somebody set me straight with some facts and dynos!

 

Crawford v.5 with the stock intake. The OEM intake is much better than most of you all want to believe.

 

Never really believed in intake gains until I did some comparisons myself of stock vs. modified intake equipped Z's air fuel ratios.

Z's with oem intakes run slightly richer at 5000+ rpms than ones equipped with the Injen, JWT, or Typhoon. I don't remember exactly but stock seemed to drop to 13.2 while the modified intake would bring the whole line (past 5000) it up a few notches to like a max of 13.5

All this proved is that they accomplished to lean out the top end and performed better than the oem intake. How much gain is difficult to calculate given the small increment and variables of a dyno.

So, no, it's not going to win you a race or feel faster. But it definitely sounds good and makes hp.

 

I dont want to post results yet, I am going to hopefully hit the dyno this saturday with the pop-charger and see how that goes. I am dyno and track testing my mods, so I'll know which ones work for sure, and which ones dont. I'll keep you guys informed. Dont want to start a thread on it yet....
