I recently installed a Weapon-R Secrect Weapon SRI not on a lancer but on my Outtie. Figured would give you a small summary since it has come up as a brand for you.

With the Outlander they were the only ones I could find that even had a SRI availiable so I didn't really buy theirs by choice. Install was smooth and easy with exception to the MAF. The mounting holes were not an exact match to the MAF and i had to drill the mounting holes on the MAF inwards to get it to mount properly.

I didn't do dyno's before and after so power gains are irrelivant but it does feel a bit more responsive in some places. Growls thorugh the whole RPM range but if i accelerate slowly it remains fairly silent. about 500-1000 rpm before redline it starts to make a small whistle type noise that is hard to describe. I tired recording it with my iPhone while traveling on the highway but the mic isn't sensitive enough to pick up the whistle type noise only the growl.

Went from ~28MPG - ~32MPG on the highway
Have a stack of receipts for in-town driving I have not gone through and recorded properly.

EDIT: Link to thread with more detail. Thread Link

stay away from weapon r... bad stories all over from these.

the filters break up and will get sucked into your throttle. my friend had this happen to his civic.

Do you have a CVT or manual, cause in my manual at 65mph im turning about 4000rpm (if i remember correctly). Way above 3000rpm that's for sure.
If you have the CVT then that's part of the problem, it's not made to accelerate fast in any "gear"(ratio). An sri would help with acceleration at low rpm's, but downshifting would be your best bet to accelerate at 65mph in 5th gear.

I think you're really in the low-mid rpm range much more than you realize. Unless you drive around like a mad man all the time, or spend lots of time at the drag strip/track, you'll get much more use out a sri for daily driving. From the dyno's I've seen an sri gives you power gains in a more usable rpm range, but less overall compared to a CAI. And a "cai for power".... in our cars your talking about 3-4 more hp's with a cai over a sri and that's at 6000 rpm, not really a lot more power and only usable when your shifting at 6k.




AEM doesn't make a V2 for the 08+ lancer. And actually they don't even make a intake for the 2.4L engine.(yet)

I have a manual.

At 65 mph I'm around 3000 rpm

Hmmm... let me check mine tomorrow morning and i'll post back. I swear I'm way over 3k, but you may be right. I'll post back in the morning with my results.

maybe 3500... but under 4000 for sure. I think that 75 is under 4000....

You're absolutely correct about 3k rpm @65, I was way off, sorry about that.
Here's approximately what I got this morning in fifth gear:

2900 rpm @ 65 mph
3200 rpm @ 70 mph
3500 rpm @ 75 mph

So to answer your original question, I would say neither is better than the other at helping with accelerating in 5th gear at 65 mph. It's pretty even if you look at the dyno's for injen and k&n. Around 3k rpm it looks like about a 2-3 hp gain for both. Where you notice the difference is around 3800 rpm to 4200 rpm, the injen cai actually dips below the stock intake figures, then takes off, where the k&n in the same rpm range is starting to gain more and more hp's and is always above the stock figures. Once you get to 6k rpm the cai is producing slightly more hp's. So the SRI wins from 3800-4200 rpm and the cai wins from 5600-6000 rpm. Other than that, comparing the dyno's, they aren't much different. So what you need to figure out for yourself is do you want your gains earlier or later in the rpm range.

Ok. Thanks... I'll study those dynos...

I've been killing myself over these facts for the past 3 weeks....I still don't know if I want a SRI or a CAI. Living in NW Illinois, I think a SRI will be better for winters here. I think they are easier to install.....Cheaper.....

On the other hand, the CAI should give you a bit more horsepower.....But....how often do I take it to 6,000RPMs? Only when stomping it which isn't most of the time....I think I might just go with a SRI.....

But I am still undecided...... (IMG:style_emoticons/default/sad.gif)

I just don't know....

Don't feel bad. It took me two months to decide which way to go and which company to go with. I did lots of research. It's better to take your time and weigh all the facts and options rather than to just get what everyone else has and what they think is best. Get what you think is best for you and you'll be happier in the end.

I know there are a few CAI intakes that will convert to SRI. Bit more expensive but maybe the way to go. Can convert ot SRI for winter and CAI for summer and if you don't like CAI in the summer leave it as SRI. I can't tell you what brands do that but someone else might be able to.

K&N does this, they call them CCA intakes (complete cold air intake), but they don't make one for our cars.
