How can the sri get more air than the stock intake? The sri is way back in the engine bay, and the stock intake is right in the front and has a scoop etc. Thanks.

I will not be getting a vented hood either.

 

I believe theres more airflow because the SRI is less restrictive or something like that.

 

It will DEFINITELY suck more air in .... the stock airbox is extremely restrictive. The only downside is that air going int a SRI will most likely be hotter than a CAI, or factory setup.

 

I've got a tool on my car ScanGuageII that tells me amongst other things the temp of the incomming air. With my SRI and RRM Hood with vent open, at standstill the air is usually 50-70 Degrees Celcius, when at 70mph it drops to about 29 C.

Im getting a CAI soon so well see what that does. Good way to measure its effectiveness.

My 2.4 engine has phenolic spacers, and we'll root ducting to air cool the manifold further, to attempt to get proper cold air going into the chambers.

 

well to get things straight, the stock intake sitting out front with a little scoop, how does the air get there in the first place? The SRI filter which sits further into the engine the stock scoop will suck just as much and even more than the stocker.

The airbox in the stock intake restricts, and I believe there are some other restrictive filters inside the stock intake.

The SRI is just a straight up pipe and filter, only a bend here or there, more direct flow. Downside = warm air.

 

I rather stick with the stock box for rite now cause im gonna go boost anyway but back on topic yea the SRI does get more airflow

 

Well if a SRI is going to suck in hot air, that will just overheat the engine right? Like on a hot summer day?

Does not sound good to me unless you have a vented hood, but then rain will be the problem when the vents are open, and too hot when closed.

 

Your engine will be shut off in anycase that your scenario happens, which probably happens once every 10 blue moons.

By any chance, your car is not going to have that problem.

And also, just consider, that almost every make of an automobile out there has an intake aftermarket, one of which will be a cold air, and one of which will be a short ram, you think that the people who ran a short ram had their engines blown out? Answer is no. You're safe either way.

 

My AEM SRI still uses the stock intake duct from behind the hood to "Aim" air at the SRI...

 

I want to see dyno pulls before I believe any intake does anything at all. My guess would be that a CAI might help a bit, but that an SRI would be a wash if not hurt you a bit in a warm climate. The only intake comparison I found online I think was for RSXs, but that's basically what they took out of it.

 

Go to the Aem website. They do dyno pulls on the SRI and the CAI for the Ralliart.

 

What would be really nice is to see a comparison of the different intakes available done on a single stock RA all at once. That's what somebody did with an RSX, and it was a very interesting test. Wishfull thinking.

Call me a cynic, but I'm going to entirely trust the graphs done by the guys telling me to buy their intake. That said, all of the testing I've seen shows that the increases for an SRI intake are very small, while the increase you get from a CAI are much better, about double in most cases.

 

Well, you can see it two ways... A CAI has more bends in it, and is quite a bit longer, so the air has farther to travel and has to go around bends to get to the motor, and can lose velocity... But it is cooler air... Think about exhaust systems... The straighter they are, the more efficient they are... SRIs usually have less tubing and bends, but can pull in warmer air...


All that said, Im still not convinced my SRI did much for the car powerwise....

 

the vents on the RRM and VIS hood dont dump out right on the SRI so it still gets cold air but rain isn't an issue. I think your underestimating how much restriction the stock intake actually has also.
