okay so ive had my injen as just a short ram forever, and finally put the CA extension on...... WHAT A DIFFERENCE!!!!

it for starts sounds alot better. that intake sound is heard at lower RPMS. the gains weren't outstanding or anything, but it made a difference, espeacially once the engine was really hot. i didnt dyno it or anything the diff. can be felt.

 

i have rrm sri. -_- there is no extension for auto's

 

injen and aem sold the CAI that could do both. rrm was one or the other b/c there CAI is a one piece.

 

Is there a difference between Injen cai and the aem cai?

 

^pretty much no... the air bypass is usable on both i believe.

 

next time you go to mcdonalds I want you to get three straws... connect two of them together and take a drink, then try with just the one... notice that it takes more work to drink through two straws???

yup, that's right... when you put a CAI on a car you kill your throttle response. also, unless you seal the front of your hood off, the same temp air is going into your filter. the one exception you can argue is in stop and go traffic, the intake will heatsoak here... but it's stop and go traffic, you're not racing anyway.

if none of this makes any sense then just remove your filter from the end since that's probably blocking airflow and slowing you down also.

 

so if a CAI has no benefits over a SRI then why would they give better #s when dynoed? oh and i think we can handle more technical talk then Mcdonalds straws.

 

I'd like to see proof of this that does not come from somebody selling the parts (obviously they will want to make money)

because when you're sitting on a dyno you're not moving and the engine can heatsoak just like sitting in traffic... in real world conditions they will make the exact same power, but the short length pipe will have better throttle response

now, if you can make a CAI without increasing the length of the pipe then it's a win-win.

 

the dynos have been discussed many times, and there is some great info if you search. put simply, the CAI performs CONSISTENTLY and the SRI performs when it is getting cool air. SRI=bad if you live in the desert.

 

I guess I'll have to put this a different way since you're missing my point that when a car is moving cold air is getting between the hood and the grill and supplying just as cool of air to the short ram (which is different then on a dyno) --

how much faster are lancers in the 1/4 or at autoX when all you do is switch between a CAI and short ram?

 

and one more thing...

explain to me how increasing the lenght of the intake path could possibly be an advantage? why not keep going and make it even longer then a CAI if that's helping?

 

it's not helping if you increase the length, it is hurting throttle response. no matter what you say, the air coming into the engine bay, even at 100mph is still hotter than the air that is udnerneath or outside the car. most of the air, due to aerodynamics, is coming in through the grill and radiator anyway, cooling your engine coolant and therefor heating the air. even if it's 100 degrees outside and you are travelling at 100mph the intake air temp will be less with a CAI than with a SRI. like I said, search if you want the theory, I am just summarizing the information.

 

But if you plan on getting a vented hood that would help a SRI.

 

okay so after hearing that in most cases seeing how im not a dessert dweller the heat of a sri and the length of a cai make then balnce out more or less.....now uyou have better throttle response with an sri which may be worth the losing the 3-5hp extra from the cai since i run an auto....? someone put me in my place if that makes no sense but i;m guessing the extra response would help compensate for what an auto loses right off the line.
