SRI vs CAI (from AEM question)

[scoobiesport]

"The CAI however is worthless and makes the car run like crap."

So the CAI from Injen makes your car run like crap?

Yes my WRX runs like crap with a CAI (I was refering to kazon's comment).

Bottom line most performance companies will sell whatever makes them money. People have it in their mind that when you want to upgrade your car you go and slap on a CAI because that is what all the hondas and Mitsus do with this in mind would you, as a company that caters to a multitude of cars sell a CAI or SRI and not make as much profit?

If you are happy with you CAI that is great. If you are going to tune more than just a intake you might regret your CAI later

PS that little rant wasnt towards you savy

 

[II-Savy]

Got it. No problem at all. I though it was just a general comment. people have been saying they really like that CAI from Injen, and I had a sweet AEM CAI in my old intergra that was pretty nice....and yea I will prolly not do too much more.

What do you mean by:
"If you are going to tune more than just a intake you might regret your CAI later"

 

[scoobiesport]

First of all let me say that my comments here are out of speculation and general learning. I dont own a MSP so I wont be able to give you facts about the car but I can give you insight on the general turbo modification idea

I agree with the people that stated earlier here that once you bump your boost up you will not want to restrict the air coming into the compressor inlet. The CAI will create more restriction than a SRI. If you plan to mod your car the "right way" (if there is such a way) the tiny I/C will need to either replaced or augmented with a CO2 sprayer. That will take care of the intake temps alot better than a CAI will.

I understand. I will prolly only do mild mods, and I understand your point, I will only go to about 8.5 psi MAYBE and CAI, colder plugs, 94 octaine(sp) and I have a cool home-made intercooler sprayer going in on Monday.

 

[scoobiesport]

Yah I thought the same thing with my car but then I got used to the speed. Now I am waiting for my COBB ECU reflash to come in. Without it I have been walking on EVOs so I cant wait to feel the car when it gets here.

Boost is addictave and I am hooked

AEM????

Bump!

Any word form AEM on the intake they are supposed to be making for the MSP?

They said about a month and it's been that.

Whoever it was that lent their car: Have you tried it?

My eyes! My eyes!!

I can't believe this is in the "Fluff" section!!

Be gone to the Performance section, At once!! Poof!!

Many good points so far in this thread.
My $0.02....

SRI will cost about $100-150
CAI will cost about $200-250

Which do you think they will build ????????????????

My money is on CAI.

I wish one of the big companies would build a SRI and have the balls to dyno it next to the CAI's already out there.
I know the dyno doesn't mean everything, but you can bet Injen sold a lot of CAI's based on the claim of 16 hp alone.

I think too that every car is different, so what works for a Subie or Mitsu may not work for us and vice versa.

The dyno's have shown that sticking a cone filter under the hood loses power on the MSP due to the hot air from the fans.
There are people here who run this setup and state it isn't true.

I think everyone just wants to think they have the best setup, despite the facts.

To each their own I guess.

We live in a Capitalist country and everyone wants make money no matter what.
It's funny to see this thread because I said it before that CAI on a FI car is a bunch of BS!! Even on a NA car the long tubes are restricitive over 8000 rpm's. That's why you con't see Integra Type R's with CAI. This had been proven with real test including dynos. Just go to www.team-integra.net or www.hondavision.com and search the tech articles. How many 10 sec cars have long tube intakes? NONE
Did you also know that the filter element is not very good and all te crap from the streets get sucked into the engine and deposited in the crank. Again, just search www.team-integra.net. There are pictures of how an engine looked like after several years of using and CAI.
For FI cars like the MSP, I also think the CAI is not the best choice for the reason already mentioned by other members and not to mention that a CAI on FI car looks gay!! My father in law has a Miata pusing 250 whp with a Bell turbo kit and he has the filter hooked directly to the turbo INLET. I am tempted to do some the same, but the MSP has all this BS sensors in the way!!

to everyone complaining about slow development, you should try visiting an exhaust shop or a tuning shop that does custom work with pictures of what you want done, it won't take them long and won't be very expensive. you'd be surprised and it would solve the patience problem you're having.

It is rather baffling why no one has dyno'd a SRI to show if it has a direct HP advantage over CAI. From what I've read so far a SRI seems the more intelligent choice in the larger picture... although without numbers we just won't know one way or another. As far as the claimed 16 hp gain from the CAI, was that on a stock vehicle, flashed or unflashed? With stock psi? And what happens to that number when combined with the other components mentioned here, ie the FMIC and boost controllers, cold spark plugs etc. It sure would be nice if someone did a comprehensive study and report on this =)

How much does a dyno cost?

 

[skilletrx]

any new news on the AEM?

 

[BinaryRotary]

It all depends on horsepower. If you need more, immediate air into the induction system via the shortest route, producing high levels of HP, you need an SRI.

Most streetable cars will not see an advantage with an SRI, until you're running higher boost levels in the mid-teens to low 20's.

you should also say NA with mild mods. A NA car with high CR and a redline of 9000 will not benefit from a CAI. It would become restricitve after 8000 rpm. I guess for most "wanna be racers" a CAI will be sifficient, but if you are serious, a SRI is better.

 

[spacemonkey]

So CAI or SRI? I know nothing about turbo but 240 guys was saying SRI cuz the turbo is going to heat up the air anyways (airflow matters more). I checked our engine and it blows hot air directly where the filter is. So would CAI air be a bit colder than SRI air? Then other guys says that our ECU doesnt like the hot air the SRI provides so CAI is a better choice, temp matters? Man I am completely clueless...I think Im just going to go with K&N drop filter. I know I'm going to be flamed for this but I just want to learn more about this situation. I know its been brought up alot and now I have the pleasure of using the search button and reading all those threads. I do want a SRI but its goign to be more $$ cuz no one makes it.

 

[03MSPRO]

what are your goals? We have already answer this. It depends on your goals/mods. I would not get a CAI because I don't want a bunch of yunk be sucked into the engine. YOu guys really need to do some research.

 

[AutoBox]

since when does a maf measure air temp? does our ecu's have intake temp sensors? thats all bs, if u want nice gain son a turbo car, a sri is the only choice, why worry about cold air when ull be turning the knob and just pushin more air in? also it needs to be stated as u increase boost ur pushin more air thru the same size piping, more air equals more heat, so a long cai may start with colder air, but after traveling thru the long as pipe its already hot, then as it hits the turbos its even more hot......its basic science guys, the more u squeeze the hotter it gets, thats why turb cars dont have cai, cus whats the point of startin with colder air when it will be nil after traveling the whole distance, at the end being more hot then air from a sri........dont follow hype, i like to follow common sense

 

[1sty]

Yes we have an air temp sensor.

 

[skilletrx]

well so.. whats up w/ the progress of this SRI? after its marketed and tested we won't have to continue debates bout cai vs sri =P
