Injen CAI=slower spooling

[AutoBox]

nortious what cars run a cai? make sure not to get it confuse with ram air......also i agree ram air is the best....i dont have to sit here and "preach"..... im offering the information i know that is fact...and to tell u the truth the best intake for a turbo car is no intake at all...unfortunatly we have a maf so we need to run that before the turbo somewhere....

daw - do u have a engineering degree....im actually goin to school for a mechanical engineering degree

unwrittenlaw - i agree cus yall need to stop gettin all pissed off and have a civil conversation

another thing that needs to be takin into effect is the FACT that the longer a tube is the slower the velocity.....hence the reason most high power FI cars dont run any sort of intake at all....unless its ram air.......its sad this thread has turned into another damn sri vs. cai thread

 

[Notorious]

I also agree that ram air is superior to both cold air and sri and that no intake is the best at all. I have quite a few friends who have 400+ hp and are running cai and the other half is running sri. No intake would be great but would only fit something more along the lines of a drag car, ie titan supra.

 

[AutoBox]

what cars though notorious? i have NEVER seen a high hp car with a cai setup (filte rlocated in fender with a long tube) i had a buddy install a 1ft long tube from his turbo the fender to get cold air but he ended up pullin it and just runnin a filter right off the turbo and a ram air tube.....alot of my supra friends like to pull their passenger headlights and runnin a ram air tube all the way to the turbo and pullin the filter when they go to the track or street races and keepin a filter on the turbo for daily driving....

 

[Notorious]

You pretty much name it, especially on sr20 motors. Almost everyone i know running an sr20 is running a cai. One of my friends has one at 438 hp on stock internals. I seen it on rx-7s, supras, 300zx, dsms, you name it.

 

[mp5jeff]

Notorious- pics would be cool =) every single turbo supra ive seen run no intake or just a filter, and rx7's with cai's? id really love to see pics of those. I assume you mean single turbo 3rd gens right?

AutoBox- finally, someone that agrees with me! thanks.

 

[mp5jeff]

if we could run no intakes on our cars(damn maf) i would be running none. or just a filter.

 

[jflo]

yeah me too...the turbo miata setups don't run any tubing. they have a filter attached to the turbo.

 

[mp5jeff]

i don't think alot of people realize that when you put a cai on a turbo car it leans out the a/f ratio and thats why their will be a gain in power, but if you just tune the car, it will be better. although that will cost more then putting a cai on also.

Umm lets see.....YOU CAN RUN NO INTAKE!
If you have a little brains(not meant toward you at all mp5jeff)at all combined with a little electrical knowledge,you could extend the MAF harness.This would let you position the MAF at the turbo inlet with a simple silicone connector and attach a HKS type filter directly to the MAF on the other side.Now ,here is the hard part.You MUST make some sort of support for the filter/MAF assbly that would support both things together.I have thought of this for a long time but cannot beleive someone hasn't mentioned it.I bet we would get the greatest gains out of this type of set-up combined with a nice FMIC to offset the heat it would suck in being directly behind the cooling fans.It would damn near suck in NO more hot air than the original set-up.
Now what do you guys think?

acctualy my brother and i were going to do this yesterday, but it just isn't worth the time(i don't have much time when not at work anyhow). Just put the maf on one side of the silicone and the filter on the end and it would probably work, but i am not 100% sure if this would work correctly but it might. But if you can get it to work let me know. Also i said i would like to run no filter or JUST a filter, not a maf then filter =) but oh well, close enough i guess.

 

[ColinsT]

no way

Well I tested the 1/4 mile times with a stock msp and an Injen equipped MSP via a HKS timer type 1. I would always pull faster 1/4 mile times with the stock one. Will have to add a downpipe to this equation and retest. I believe the downpipe will improve the turbo spool and make the Injen equipped MSP faster than a stock air box MSP with DP.

That makes no sense, fast with stock airbox, How is that mossible when you gain Hp with Injen CAI, that horse s***

 

[mspdfreak]

All I know is that I see alot of "my friends say", and "the Supras do this", and a whole bunch of other undocumented bulls***. Now unless Injen (or any other cai manufacturer) is just flat out lying, then they do provide power. Look, if these people were lying just to make a buck, then they would have been reported to the BBB a long time ago, and probably would be involved in a class-action lawsuit. It's common business sense, people.
The characteristics in the added power vary, I'm sure, but unless you can show me some numbers that prove no power gains, here's what you do....wait for a really dusty day. Pull off WHATEVER setup you have, and run that ****** like you're trying to outrun a nuclear blast. Oh, and just cut-off that MAFS, it will add another 15hp. (it has to, my friend did that on his '86 IROC Z28, and he says it does) Now how does it run?

 

[AutoBox]

oh no im not sayin a cai doesnt make power...just that it snot efficent in doing that on a FI application.....

notorious - i came from the rwd sr20 240sx area and NO one runs a cai....for starters the turbo placement is FARAWAY from the fender and they would make it really long...and second the IC piping usally dominates the fender area anyway....i know of 5 garages on Freshalloy.com that were competeing with each other on who can produce the most whp on a stock block and all 3 didnt run filters at all....other two ran intakes that placed the filter behind the heading so they could pull it and get the same effect as the supras do.....as stated i really would like to see pics of the cai setups u speak of cus i have honestly never seen them.....and dont feel i am sayin ur lying...just sayin its rare in my book to ever see a cai on high horsepower applications.

subaru wrx doesnt make s*** with a cai....most use the stock air box or just a cone filter on it up to 300whp or more.....i wouldnt say our stock system is great...but its not horrible

in the end this debate can go on forever...everyone can have their opinion and use it on their car....if ur undecided on which route to go...take the info here and hopefully it helps

Its not horseshit...the CAI makes more power, just in a different area of the power band than the stock box does.....


I love the hostility on this board

 

[Turbofreak]

hey have any of u guys ever ran a pipe bout 2.5 to 3 inchs
derectly into the filter on an injen set up? i mean not puting
the pipe right on the filter because stuff will go into the
filter but i think of it as a ram air. running it from the fog lite
to the filter. Could it happen? more air, more power hehehe

 

[AutoBox]

for a real ram air effect u gotta have the tubing from the fog lite run at the filter and directly up the filter tubing....another thing is our MAF's are not gonna like a TRUE ram air setup....if u switch to netrual or get out of gear for too long while driving fast will cause the car to stall and shut down...this happened to me on my 240sx before i went turbo.....in either case ill show u guys the stup im designin in a couple weeks hopefully

i dunno i see quite a few. I have a good friend here that lurks on the boards who has a 400+ stock block sr20 on a 200sx running a cai. I think his handle is hotshotsr20.

 

[AutoBox]

ah a fwd sr20.....hmmm is the turbo in the stock location (behind the radiator and in front of the engine) or did he relocate it? the few fwd sr cars i have seen usally just run a sri to the back of their headlight and pull the lite when they go to race......but its all good...like i said before....to his their own

 

[Notorious]

yep i seen the same setup. I'll try to dig up a picture of the motor when i get home.
