I'll let the pics do the talking:



182.7HP 162.2TQ

Yes...thats right 12HP and 10TQ. Notice how fatter the 2nd lobe of VTEC is. I was totally suprised by this....so was the guy who runs the dyno. When I first pulled in and popped the hood...he said "be prepaired to be disapointed". After the first run he aplogized. Either way...you guys owe me some money!!

I'm sure the Injen is responsible for some of those ponies Jab, but do you think maybe having the more miles on the car this time around was a factor at all.

Either way, very nice numbers.

One more question, how much faster does the car feel now?

Jab31169

I'd say Injen was responsible for the MAJORITY of those. Since most of the stock dynos have been in that range. Plus I had about 2000 miles when I did the baseline. With a 15% drivetrain loss you are now looking at 210HP/188TQ

Yes the car does feel faster...the wheel hop is a ton worse now.

fdl

short ram or CAI?

Jab31169

CAI

TinkySD

that is awesome. breakin probably is a little involved. But those are really big gains. A little bummed about the dip in torque at 2500-3000 but the midrange gains are FAT. Very nice work jab.

Jab31169

I'd say the thing that would really make this car faster would be lighter rims. After talking with the guy at the dyno I am now going to save up for some Centerlines.

TinkySD

i now have way more respect for injen and less for comptech...wtf?

TinkySD

Yeah totally, cartest2000 estimates about .5 seconds faster 0-60 and 1/4 with lighter rims/tires. That's with 36lb wheel + tire combo versus stock.

Jab31169

see....thats what I dont get...how they only pulled 13 ponies out of I/H/E.

TinkySD

oh btw, any reason you didn't run the car up to the rev limiter? I would be interested to see if the top end continued to increase all the way up.

Jab31169

I ran it to 7300-7400 via the tach which is about 100 off apparently. But I dont like boucing it off the limiter....just one of those things I guess

TinkySD

I am post whoring this thread. :-P Anyways i was probably not going to get an intake but those midrange gains are super nice for day to day drivability. You lose a couple pound feet from 2500-3000rpm but that strong midrange sure makes up for it.

dom

And the nice thing is we should expect the same gains on our Auto's.

TinkySD

The injen dyno on their site is from an auto. Gains are exactly the same. Just off about 5% for the extra driveline loss.

ricecake

interesting, and a pleasant surprise, Jab! thanks for making a girl (with the install in CAI mode too) happy.:-*

I'm not surprised by lower torque on the lower rpm range--my understanding is that that is par for the course? But then again, you get slightly better fuel efficiency b/c the air-to-gas ratio is better?

Jab31169

Talking with the guy at the dyno...some sort of VTEC controller would do wonders as well....by not only lowering the VTEC but bumping up the fuel in the higher RPMS would give a nice gain.

fdl

Hurry up HONDATA.


ANy guesses on how much wrose the short ram would be?

Jab31169

after it heats up I would assume 3 or 4 HP/TQ. I personally dont see a reason for the SRI....its much much louder...almost too loud.

TinkySD

Yeah now that you have the cai mode going what do you think of the sound between the two. Is the cai subdued enough not to be obnoxious?

Jab31169

Yea....the SRI was too loud. You only hear the CAI when your wide open and its a nice sound. I know my gas mileage has gone down cause my foot always has the gas pinned to the floor

gavinn58

that looks pretty good on the high end, but what's really nice is the hp/tq bump from 3500-5000 rpm where most daily driving is done. 10hp and 10 lbs of tq is nice from an intake. Too bad it dips a little from the get-go and after 5000. Still a nice product though...definitely worth it imo.

Lung Fu Mo Shi

See? I told you guys. There is little meat below about 3000...then it just seems to really pick up from there.

And yes Tinky...I have the same problem. Gas pedal + floor = bad mileage.

What's cool is that if you just daily drive around town, you almost never hear the intake. It's only present with you're 3/4 throttle and above. However, going up a 10% grade with full out throttle gets REALLY loud...but then, that's half the fun.

Aric

i feel the extra low-mid range torque as well. i found myself driving around town slowly mostly in 3rd gear nowadays where i had to shift down to 2nd before.
and i wasnt too impressed by the high rpm.... now after looking at the dyno, that explains everything. also, the rpm seems to go up a litl slower with the CAI. someone told me that's why you dont see many tuners in Japan that has CAI.
i guess a good flowing exhaust might pick up some ponies in the highend.

Jab31169

How are you not impressed with the high end? The car screams over 6000RPM's. As for the RPM's going up slower...neg...the car gets up faster. Half the thing about SRI and CAI is the fact it makes it easier for the car to breathe. With the resonator gone air enters the engine with more speed alowing the engine to accelerate quicker. Also on another note, the dyno can determine how long it takes you to get to redline. On my first run it took 13 ticks compaired to 14 for the baseline.

Aric

did you feel the throttle becomes a litl heavier at low rpms? and the rev doesnt go up as quick as before? at least that's how i felt. but hey, you have the numbers...
as for the high rpm, i wasnt impressed when it was stock compared to the rsx-s(stock) i had before, even with the CAI now, i still dont feel much diff. the engine is just too "peaceful", if you know what i mean. and honda forgot to gave us another 1000rpm before it hits the redline.

on a sidenote... i just had my filled some gas this morning. last tank i was flooring it all the time, so i couldnt compare the gas mileage. but from what filled this morning, the mileage seem to get quite a bit better. need a few more tanks to be sure though.

Davediego

stock acura intakes have almost always been EXTREMELY restrictive. glad to see a CAI does wonders for a TSX as well

Jab31169

Seriously...the only time my car is below 3000RPM is when im starting from a stop, comming to a stop, or sitting at a stop sign. Now im not doggin it all the time but I dont shift untill 4000 and when I shift it drops to a hair below 3000. The tach does move faster...you just have to be over 3000 to notice it. I know what you mean about the RSX but then again its a sports coupe. I belive our car was "mellowed" out for the reason its a sport SEDAN. Acura feels like if you want the performance you'll go with the RSXS. If you have the money and want the performance and luxury you'll go for the TL. If your looking for a good mix you will go with the TSX. Lighter wheels would do wonders for this car. With the RPM's you could shed 10lbs a corner. That would be nutz

Stokeless_TSX

i really wanna have someone with a injen come to a dyno with me and dyno my car withmy custom one and then again with the injen to see if there is a difference. is anyone in seattle down? i dont want to spend the money on it if my custom cold air makes better power

Aric

if you want to pay for the dyno, i will pay the gas.

Jab31169

speaking with my main man at the dyno and after I saw my gains I asked him about your gains. Talking with him we therorize you may have freed up too much backpressure with the custom exaust. The best thing for you to do would be to put the resontator back on and see how you dyno.

sauceman

I am in shock. I was like heheheh look at his optimism get beaten to death by a dyno. Instead, I must say wow, that's a good bang for the buck. And I especially like the midrange gains.

My next question: Is the filtration capacity up to par?

TinkySD

injen's use k&n filters so I guess that question is if you like k&ns or not!

Stokeless_TSX

ill pay for the dyno lol no problem if you wanna set up a day to meet up and head over there...i dont think i freed up too much back pressure...since i plan on turboing the car anyway. resonators dont give alot of back pressure anyway but i see your point but i dont feel like cutting up my nice piping and adding something in im gonna take out. V6 engines use 2.5 inch piping and sometimes are only .1 or .2 liters larger displacement than us. we have vtec and that will move alot more air than a standard engine with no vtec so im confident i made a decent choice with the 2.5 inch exhuast. once i turbo it ill be pushin alot more air and 2.5 inch exhaust will be ok if not too small

sauceman

Well it gets even better! I was wanting to get K&N filters and was about to compare to K&N, so I'm getting pretty excited here..

Last question: My last car died because I had a CAI and swallowed up too much water. I didn't go underwater with the intake, but there was just soo much splashing and all, the engine got a sudden big gulp and stalled. Later, it threw a rod on me. Where is the CAI located, and is it prone to swallowing lots of water???

Jab31169

The filter sits right under the headlight. The little compartment it sits in seems rather watertight as far as splashes and other stuff goes. The only way I could see someone hyrdolocking the engine would be burying the nose of the car 2ft deep in water. Im waiting for it to rain again so I can open up that compartment and see how wet/dry it is in there.

sauceman

K. Keep me posted please.

wiz

Wow, I have been away for too long it looks like. I need to get back into the game and maybe the CAI is the thing to do. My father is always looking for something to mess around on car wise and this might be a nice project for him and I to partake in. You wanna hit me up with an e-mail Jab and fill me on on where you got the CAI and how hard it was to install and all?

Thanks

Lung Fu Mo Shi

There are some other instructions, but this is what I used (Helms manual and provided Injen instructions)

i think ultrarev has the lowest prices wiz.
