anyone have maf problems while using a short ram intake, like lean or rich conditions. i want to get one, but have heard stories of lean or rich conditions due to the added air flow.

 

no problems so far. read the Reviews portion of this site, they're there for a reason. I posted a neat lil review of the intake so far...

but if i was to do it again, I wouldn't go...didn't help my performance at all. if i was to think, it probably hurt my performance. if you see how hot the filter cage gets after a spirited drive, you wouldn't get it.

 

intake=wasted money

 

so...u really dont need intake for WRX eh?...not even CAI?

 

i mean...its not nessesary?

 

why use CAI when the turbo is gonna heat up the air anyway?

 

oic....so....might as well have a good intercooler than having a good intake

 

An intake is just one part in the "overall plan" of tuning.

My $0.02 is you don't "need" one till you have engine management.

You have an STi right? The 1st mod I recommend is a down-pipe. But I don't know if you dad will go for that, he's the owner of the car right?

But really all you need to do is clean up all the little sloppy areas of the STi. The streeing and shifter bushings, brake lines, springs and lateral links are weak areas. After doing that you'll be able to drive the car faster, with the power it makes stock.

 

man thanks for the help guys. i know i'm really spoiled but thanks. i'm really looking forward to the ewa install day. i'm just gonna go to watch, cuz i can't do jack to a car. anyway, i'm gettin a viper v791 transponder for my car on monday. my friend with an evo8 is gonna do it for me.

 

glad to help. this is what i-club is about.

 

That's like saying "Why use an intercooler if the air is gonna be used for combustion anyway?".

The turbo will heat it up a given delta T. Cooler air to start with will leave the turbo cooler (and denser) than warmer air.

However the stock intake on the WRX is already a CAI and has been shown to be as good as (and in many cases better than)aftermarket stuff you'd buy.

 

My whole point was that it would be heated up while passing through the turbo anyway. Afterwards, the air would then pass through to the intercooler, then to combustion. Therefore, I don't understand your analogy.

intake -> turbo = heated anyway.

intercooler -> engine = denser(colder) the better.

 

For a given turbo at a given load the amount of heat added to the intake air is a fixed amount.

So if a stock turbo heats up the air 100 deg then intake air at 80 deg will leave at 180 while intake air at 120 will leave the turbo at 220.


BTW - for the Physics/Engineering majors out there. The first paragraph is not entirely true but for the purposes of this discussion it works.

 

From the CAI discussion in the tech section:

i think you mean to say that the amount of temperature INCREASE across the turbocharger is related to how much work it's doing.

clearly if you put 200 degree air into the turbo you will get hotter output temps than if it were 20 degress, providing the pressure ratio stays the same.

also, when measuring the temps "post intercooler" it is very clear that cooler ambient temperatures allow for a lower post IC temp.
