CAI vs. SRI

RRM says something about 10 whp with the CAI, but the SRI offers a second off the 0-60.

I've been reading the forums for about an hour trying to find graphs or real data. At 150 and nearly 200 for them, I only want to buy once.



Oh yeah, I fully enjoyed the AEM vs. INJEN threads.


Anybody have any real numbers that relate to these products ?

Do you KNOW or have any numbers for any of this ? I'm just trying to get some opinions and advice. And its 0-60 not a 60 foot time. Do you have any data or not?


Dumb or not, its on their website: http://www.roadracemotorsports.com


ROAD/RACE SHORT RAM INTAKE- for Ralliart-

AUTOMATIC and MANUAL TRANSMISSIONS




This intake fit both Manual transmission and automatic transmissions. Expect to drop a full second in 0 - 60 mph times with this intake as the MIVEC kicks in and this engine culps in air! This kit includes all parts needed to install the intake without damaging stock components. CNC machined MAS sensor holder and adapter bolts right up and the kit includes the largest filter we could fit in front of the battery! Powder coated red only!

$139

ROAD/RACE Cold AIR Intake for Mivec engine. VERSION 2

This is our own creation.The new version incorporates a CNC MAS housing for better flow and a cleaner look. We use nothing but the best components to increase power! This intake alone will yield anoth 10 h.p. Powder coated red, it comes with all hardware and cone filter. For 5 speed only!

199.00
I dont know if I should assume your being an *** or not.

Nobody has actually gone out and compared the before and after for each of the intakes. Everything is speculation.

pretty sure I've got some good "proof" that no Short Ram Intake is going to drop your 0-60 mph times a FULL second. Lets do a simple comparison between your car (a 2004 Lancer Ralliart) and a car whos 0-60mph time is one full second faster.

Heres the specs of your car and where I found them...

2004 Ralliart 5spd 2.4L
162 hp @5750
162 tq @4000

2843 lbs

0-60: 6.9 (MotorTrend) - 7.3 (Car and Driver)
1/4 mile: 14.97 (MT) - 15.4 (C&D)


and heres the comparison car...
the INFAMOUS SRT-4...

SRT-4 5spd 2.4L
230 hp @5300
250 tq @2200

2900 lbs

0-60: 5.9 (Road And Track)
1/4 mile: 14.5 (R&T)


NOW notice, the Ralliart 0-60mph is excatly one second slower than the SRT-4 (6.9 vs 5.9). And the weight is almost exactly the same and they're both FWD. So for your Ralliart to knock one FULL second off its 0-60mph time, I ESTIMATE it needs to gain about 70 hp. (SRT-4's 230 - Ralliart's 162 = 68hp)

Now if there is ANY air intake that can give you a 43% increase in hp, Then by all means, buy it...

I find it weird that you're wondering about two intakes, one which claims to drop a second from your 0-60 mph time (add 70 hp) and the other who claims to add 10 hp.

I'm not trying to be an a$$. Just use your head a little man. However, if I have been an a$$, I apologize...

I say if you are in a relatively dry area, get the CAI. They look cool. The sound cool. They add horse power.

If you frequent to the axle standing water, don't take a chance, get the SRI. It sounds a little louder in my opinion, but doesn't have the same sucking sound as the CAI.

I think the SRI will give you better throttle response, but the CAI will give you colder air on the top end and maybe 1-2 more HP because of it. I suppose you can't really go wrong with either. The SRI is obviously more easy to get at and clean the filter. But my vote is for the CAI.

ovenmit331, Your point is made... yeah, I agree 100%. I was wondering if these things were that congested at the intake.

We dynoed our CAI, Piggy, and exhaust. We got really good numbers. See the site. We datalogged the SRI and got .85 second faster 0-60. That is for sure. CAI will yield higher peak power numbers for sure but in some applications power band for CAIs are steepere the SRI. SRIs typically yield a little better low end and midrange power than CAI. See sample below.
Both are big improvement over stock considering that stock intake has baffles and other appendages that harm smooth flow of air. A lot of why stock ones are like that is to vut down on noise etc...

I can see close to a full second after SRI, exhaust, and tuning with the piggyback, but the way you advertise it (as 6.9 0-60 before, bolt on SRI, 5.9 0-06) with no tuning or anything else, just not possible...
