Hey all I have a quick two part question about tuning and my Typhoon SRI.

First off I have a 2014 Civic SI which at the moment is straight N/A and will remain that way until the vehicle is paid for, at which point it will become my project car and I will go in the direction of a Turbo or SC with mid range boost. But for now, I am fine with N/A, and am in no hurry as this is going to be my daily driver for some time to come. Second in my effort to be "awesome" I installed a K&N SRI about a month ago( this was before I decided that boosted was the way I was going to go), with the assumption that with a future purchase of a Flashpro and a tune the ECU could be made to "understand" the added air flow from it and it would be able to utilize the added air to its benefit as opposed to the restricted airflow from the stock intake and make a few more horsepower.....or at least run more efficiently. But it's looking like I was wrong.

I also, per research, suggestion, and the overall great tone, have decided to purchase a Full Race Catted DP as well as a FR 3" exhaust. Figuring(intake aside) eventually I will be needing a bigger exhaust to compensate for the SC.

I had planned on keeping the SRI, installing the DP and exhaust, purchase the Flashpro, and get this thing tuned up! Then when it was time to go full bore into forced induction start purchasing the needed upgrades, sell the SRI on ebay, and go on my merry and boosted way....

But....Last night I had a short email correspondence with a reputable tuner. And it was his expert opinion was that my current setup sounds good as far as the DP and Exhaust, but the SRI would ruin it because it would mess with the MAF and therefore the potential gains I could be getting through a proper tune with the DP and the Exhaust wouldn't be much. He explained I would get a better tune of the stock intake. Now, I trust his opinion completely as I know he knows his S. Of course I feel like an idiot for dropping $300 bucks on a intake, but ya live ya learn. And I want to do this right.

I'm just wondering why the intake would be such a detriment to the car. I guess I figured that with a tune it might actually be a benefit. Of course I guessed wrong. lol. Anyway, long story long. In my effort to better understand this, and not wanting to bother this dude to no end with questions because he's probably tuning some of your cars as we speak I figured I'd come here and get a little more clarification on this.

Should I return the induction to stock, sell the intake on ebay to some dude who likes a cool sound it makes, Slep on the DP and exhaust, then get a Flashpro and a tune? I plan on slowly working toward forced, And I know most of the other mods gearing up to support that will be added eventually, and I don't mind retuning it along the way. I have just heard so many great things about FlashPro and this particular dude, I wanted to get a solid initial tune to enjoy the benefits while I wait.

Thanks guys I know that was long, but I want to get this right, and any help is greatly appreciated :-) I would just ask the dude, but like I said, I haven't paid him any money yet so I don't expect that he should give me any more advice then he already so graciously did!

The factory intake on the 9th gen seems to be pretty good. As I mentioned, King advised only changing the down pipe when doing a tune. I didn't question why...

And I'll tell ya what. If I'm going to get the same results with just a DP and my current setup I'm all for it! it's a $600 difference! $$$ That could go towards new rubber

Now we're talkin'!

Who was the tuner out of curiosity?

DP and a FR 3" exhaust she give you way better results for sure. The exhaust will make a huge difference with the DP.

As for the intake not sure about that... could be that the SRI just don't get great gains. Try to see if anybody has done any dynos before and after the SRI install.

Dmise1982

Got the answer! Thanks all :-) and in case you're reading this FOR the answer. The answer is, don't buy a short ram Intake, they have the roar of....um....a mad growly bunch of tiger sounding awesomeness, but the actual power production of a little tiny baby tiger cub. In essence they do not walk the walk, only talk the talk. Lesson learned. Thanks again :-)

Hahaha sounds so like something he would say too!

FYI I put the car back to stock induction today and gained 20whp and 20ft/lbs tq! LOL. So for now I lost my awesome little whomp whomp sound, but considering I'll be getting a Full Race actual whompity WHOMP soon, I can't complain.

ok..only two SRI that make power are the PRL and Rickspeed. Second, with our cars you need flashpro to get any HP gain from intake, DP and Exhaust. you should do some research on the 9thgen forums, alot more info there. FYI i have a PRL SRI and Fullrace Catless DP.

Dmise1982

Yeah, I made a profile over there yesterday. Great stuff. Of course I've spent 80% of my time in the boosted forums dreaming about the distant future. Lol. But nevertheless, been all over the site and it's more 12-14' specific, which is great! I tend to spend my time going back and forth here and there. As far as Flashpro, hell yes I'm going to get it! Right after I get my DP and exhaust next month. As well as an ultimate tune. The way I see it is there isn't any reason to spend good hard earned money on quality aftermarket stuff to have it A. Not do anything, or B. End up screwing the engine up. That was part of the reason I went back to stock induction. Let me ask you this, what is it about the PRL and RickSpecd that has the ability to work so well with our cars over the other big names?

They are CAI's and 3.5" as opposed to 3" found in most others. I would bet the new version of the Injen makes decent gains as well, but it still isn't as big as the other two (but has a much easier battery relocation method).

The SRI subject has been beaten to death on both 9th gen forums. Unsurprisingly, Vitviper (the tuner) has established that they just don't make consistent power (or none at all).

MessGSR

thats not true, on vits website he said himself " I was pleasantly surprised by the solid low end gains from 1700 rpm til 2500 rpm — as much as 12 ft lbs of torque to the wheels will definitely be something you can feel during normal stop and go driving. Slight loss from 2750 rpm to 3000 rpm though — nothing major. And no real gains until after ~ 5700 rpm, with a maximum of 4.5whp was had from 6750 rpm til 7000 rpm. Not a bad gain for a simple mod — I’ve seen much worse performance from some intakes on this platform (worse than stock intake at times)."

Sorry for the confusion as that intake was included in what I was talking about, as it's the only 3.5" SRI (and the only one he recommends). Relax.

In general, SRIs don't give much of a power gain, if at all, on most cars. This applies to the older Si as well. The stock Si intake takes in colder air from the wheel well; an SRI will take in warm air from the engine bay, near the header.
