Alright.. Alright... After reading a recent thread and seeing that the stillen high flow intake is the same or better than PRCAI AND I don't have to cut a hole. Im sold... So where can I get the best price on one???

 

I ordered mine from Stillen for 175$.. if you call you'll get a better deal than what's on the internet (backward isn't it?)

 

Not even going to give the OSCAI a try, huh DeaZal? FWIW, I've tried them both. And while the Stillen intake will give you marginally better performance at high rpm, the OSCAI will provide practically the same level of performance on top and better torque on the bottom. Still, if you simply MUST spend your money on a Stillen Intake, who am I to argue with you?

 

So the Oooglie is going to give me better low end?? how so? Alo I have a amsoil air filter.. would I be able to use that?? dont think so.... How is the Stillen compared to the JWT?? I heard the JWT sux...

 

Who told you that JWT sux? Just curious.

I put a JWT on 2 days ago. On my way back from the shop, stepped on it and it almost scared me.... Max wanted to take off the ground

I can definitely feel the difference in the higher rpm band, and the sound is sweet too. I have no experience with the Stillen intake, but I have heard that it basically gives you the same result as the JWT... at 2X the price.

 

It has to do with changing the intake geometry. I'm not a an engineer so I can't give you a scientific explanation. But I've read enough posts and had enough of my own personal experiences to know that it's true. Again, the Ooglie won't give you better low end, it just won't reduce your low end like a cone filter will. Also, your Amsoil filter will work just fine, although I've got both an Amsoil and a K&N and I prefer the K&N.

 

So its going to hurt my low end? hmm i dunno, how much?

 

Enough so that a number of the guys with cone intakes (including me) removed them in favor of the OSCAI. It's up to you, of course. Considering that you'll pay $175.00 for the Stillen Intake vs $25.00 for the OSCAI, why don't you try the OSCAI first and see how you like it? You can always buy the Stillen Intake later if the OSCAI doesn't give you enough of a performance increase.

 

O.k O.k.. Ill try it, so do I have to order that panel filter? Someone give me link to thread on exact directions.. Ill make it a sunday project.. So do I have to alter anything? or shall it just bolt right on my 2k max se m/t???

 

Check page one of the "Installation Instructions /How-To's For..." sticky at the top of this forum.

If you already have an Amsoil panel filter, you don't need to order a K&N Panel Filter. But as I said previously, I've tried both. And I do notice a little better throttle response with the K&N. If you want to get a K&N Panel Filter, add another $40.00 or so to the cost of the OSCAI. So your total will come out to around $65.00.

 

the main question was comparing a stillen intake to a place racing cold air intake...we all agree that the place racing cai performs much better than a normal hot air intake

don't get the stillen...pr cai is a million times better...i used to have a custom intake that was a little better than the stillen (it had a short pipe rather than no pipe) than i went to the oscai setup and now the pr cai...i am happier than ever...the pr cai has a nice amount of added performance along with one of the nicest sounding v6's i have ever heard...in my opinion, and many of my friends opinions, it sounds just like a turbo...i have pulled up next to someone and revved up a little and they have refused to race me because they were like "damn, that things turbo'd...no way"

 

Mr Burner thats a sweet looking kit do you have other pics that show the sides and rear? Who is the manufacturer of that kit? Thanks

 

If you pay $175, you're definately paying too much. Look around and you'll find it for less........

 

yeah, you can get a pr cai for around 200 on a group deal through custommaxima.com

I live in Florida where there are sometimes puddles a foot and sometimes a foot and a half deep when it rains. It seems that the OSCAI , from all the pictures I've seen , would take in quantities of water. I'm afraid even if my engine performs good for the next few years If i had a CAI that it would in the long run hurt engine.

Also, is Stillen an improvement overstock. Basicly, is the high end added to the car worth the sacrafice of the low end of the car? Will your performance from 0-60 increase of decrease?

 

i would be more worried with the stillen intake...on our cars, i have never heard of anything going wrong with the pr cai, but i have heard of tons of things wrong w/ the stillen intake...the reason i took off my custom intake was because my engine wouldn't idle or anything and it ended up costing $1200 to fix (since i didn't know anything about my engine at that time and i couldn't fix it myself)

 

I dunno now... Wil the PRCAI take away from low end??? I don't want to lost ANY low end.. What shall I do????

 

I'd recoomend you start with an OSCAI and see how you like it. You will NOT lose low-end torque with an OSCAI and you do not need to worry about ingesting water through the OSCAI tube if the upper air scoop is functioning properly. If the OSCAI doesn't give you the performance you're looking for, you can always opt for a Stillen Intake or a PRCAI later.

 

Has anyone tried this yet?

Take the long intake pipe that comes with the supercharger;, that brings the intake to the front of the engine. Then put your big JWT or stillen filter on that. You'll get cooler air since it is in the front, with the air only having passed through the radiator. I know this air is warmer than a true CAI, but it should be cooler than the standard stillen intake. The longer intake length should pack the air, giving you that low end torque.

 

The JWT is identical to the Stillen unit. Get the JWT, save $60, and spend it on the cleaning kit ($15).

 

Why don't I ahve to worry about water with the oscai? I cut a hole in my splash guard and added a scoop??

 

The stock air scoop will act as a bypass in case water does get up the tubing....

 

If there's a forward facing scoop on your oscai setup it's possible for water to be forced up the tube to a height that's above the water depth of the puddle due to forward vehicle motion, perhaps even above the junction with the stock air scoop. Ram effects work with water, too (ram water intake?). But if the open end of the CAI simply faces down or if the scoop faced backward, intake air suction upstream of the air filter (the atmosphere side) would not be by itself strong enough to pull water up the tube much past the water depth outside as long as the stock intake duct is not blocked.

Maybe a scoop with a cable control for which direction the open end faces would be a reasonable solution if you face really wet conditions on a frequent basis. Even for wet trips on the highway, 18 wheelers can throw off a lot of water, and I wouldn't want to guarantee that no water could find its way up the CAI under those conditions either. You could point the scoop forward on good days, backward on the nasty ones. Or cable control a door to simply shut off the CAI.

Ok.. why is your car a rolling tesla coil?

Large stereo w/ capacitors?

 

Interesting point, Norm. It strikes me you'd have to hit the water pretty hard to draw enough of it up the OSCAI tube to cause damage to the engine. But given the fact that putting a scoop on the end of the OSCAI probably doesn't increase performance at all over just setting the end of the OSCAI inside the splash guard, why take a chance?

 

How do we know it does not increase performance?? I already did it .. I cut a hole 2" around and stuck a rigid shop vac extension through it.. (forgot digi cam today at work

I head the issues with turbulance..

But I still think that with the added pressure( taking 3" to 2" and having that face incoming air at 60+ mph would be overbearing to consider that.

I dunno

 

Mostly I was addressing the following items previously mentioned in this thread, taking them in combination:

You wouldn't have to be moving very fast in a foot deep puddle to push the water up a little more than about one extra foot with any kind of forward facing scoop or CAI inlet. More likely is suddenly hitting a puddle that's only a little deeper than the bottom of the scoop. Only a few feet of travel would provide exposure to enough water volume assuming a speed sufficient to generate sufficient pressure. Guess I could dust off a Fluid Mechanics textbook and determine what that minimum speed might have to be.

Once in a foot deep puddle, water in the tube up to one foot above the pavement can't be avoided. I don't know much about how fast water can pass through the filter, but I do know that you don't want very many cc's to sneak through at any one time. Valves can be bent from the uneven cooling caused by large drops or small streams of water striking them long before the quantity of water is sufficient to hydraulic-lock a cylinder. There's a small block Chevy head with a couple of bad valves laying around somewhere in my garage as silent evidence of this very type of damage (don't ask).

Agreed, power increases due to ram air effects are minimal, but it's probably a more significant increase if the comparison is against locating the open end into a region of local low pressure. That's mostly what a scoop down there does, it just makes sure that the inlet is in a region of slightly positive pressure rather than slightly negative. It would really be nice to have access to Nissan's aerodynamic info for a better idea of what's going on down there and mod accordingly, but since I doubt that'll ever happen, well, strands of yarn and a cheapie computer camera anybody?
