What is the difference between the JWT Pop Charger and any one of the CAIs offered? Price of the CAIs is comparitively higher, but I am entrigued why so many people are selling theirs.

 

off topic, but you ever plan on selling that Silvia?

 

this is exaclty what i want to know...i would like to hear everyone's opinion about which is better?

 

Well I have a Injen and I want to sell mine and get the Pop charger b/c I want to add a Mines Air Intake Duct to it. And its easier to clean the filter. My Injen is really dirty already and I feel to lazy to remove it since it can be sometimes hard to get to. And lately there's been a lot of hype about the filter in performance gains.

 

how exactly does the Mines Air Intake duct work. I have seen a pic of it, but can't figure out the specifics of it. thanks

 

Its a hole in the F bumper for a "ram air" effect.






I like the way it looks. It looks mean!!!

 

It looks mean but this RAM duct might not show any gains over CAI because you're not really utilizing a full RAM system. You are really only cooling the intake charge similarly to a CAI. Instead of moving the filter to the grill area, you are moving the bumper from in front of the filter.

The good:

Coupled with a JWT filter (which appears to be superior to the K&N ones packaged with the Injen kit) you should see some additional gains.

By not elongating the intake track, you may improve throttle response marginally.

The bad:

It is not a true RAM air setup so you won't really gain that much over an Injen CAI with a JWT filter popped on the end.

You will not be able to return to stock because you just cut a hole in your bumper.

All in all, if that vent didn't cost so much I would get it and use a JWT filter on the end of an insulated Injen top tube. I think that would be the optimal intake setup for the Z considering what we have available. It does look sweet!

The longer the intake tube the LESS throttle response you get. There ONLY ram type intake out for the Z is the K&N filtercharger. The Injen is out of the engine comp. solely for cold air purposes. The ONLY downside to the Mine's hole is it is irreversable without changing bumpers or expensive it-won't-be-the-same body work.


As a sidenote, the last few times I have driven the Z, once a hard drive and once a 5 hr road trip, I jumped out and popped the hood immediatley and put both hands around the Popcharger. Not only was it not hot at all, it was almost cool to the touch. I don't think that heat is much of an issue even under the hood with the heat shield in place. It was not much warmer than the outside air. The summer test has yet to arrive.

 

Wouldnt you have the same problem with water as you could with the CAI etc If you used the mines duct. Water could go straight into your filter?

 

Yeah thats what meant to explain above. But I think I'd rather spend $500 on an ECU before the Intake Duct... for now.

 

So what exactly is a true ram-air system like?

 

The K&N is as close as it gets for our car. I guess GruppeM is also a decent example.

It uses the cars velocity to channel air through a tube, across an enclosed filter element. It decreases intake charge temps and increase intake velocity. You can't really have a true RAM setup by just cutting a hole in your bumper and using a cone filter.

FLY BY Z - I don't understand why you're correcting me by rephrasing exactly what I sad.

 

I don't recall addressing you or your post. I also recall typing different info than you did. I also recall not repeating your post. Why don't you get off my nuts man. I feel like you are cyberstalking me. You do this all the time. Knock it off.

 

edited that one out

 

My bad, dude. I don't know what you're talking about but whatever.

 

So if the Mine's airduct extends all the way to the stock airbox (enclosed filter element)replacing the plastic stock airduct with a tight seal in between, then by your definition, it will be a true Ram. Hmmn, something to think about, might be simple to fabricate.

 

Yes, the Mines does create a ram air setup. And yes, I think one could be fabbed for much less than 4 or 5 hundred dollars.

 

Yea you're right about that. It wouldn't be simple, but it wouldn't be expensive. I saw a JDM part that extended a little further toward the bumper but it wouldn't be the right shape. It's doable though.

What does the duct cost? Figure the fab'd part, probably made out of sheet metal, would only cost like 50 bucks. Then you'd have a pretty good setup. Drop in a K&N filter and you're in business.

 

My question, so why are the CAI's and the popchargers such the rage? Why hasn't anyone tried and dynoed a true ram air or "close to ram air" design!? If my Z wasn't in storage maybe I would be trying it Sorry, don't seem to complain to everyone..it just seems like someone would have done this already!
