K&N Typhoon, great product, Dyno proven.

[AaronWRX]

October 30th I dyno'd my car stock, then with the K&N Typhoon. The car made +12.76 whp and +11.97 ft-lbs of torque with the Typhoon. I was very surprised and very pleased!!!

The AFR's remained virtually identical.

Here is my graph:

I've been on NASIOC for 3 years now and have watched the vendors and users go back and forth about intakes. (maybe the bigger debate is why so much squabble over a mod that only gives you some extra power in the higher rpms...)

so here is a good summary:

I have a completely stock 05 STi that I've held off on modding. This saturday, at Mach V, we are going to baseline my STi stock, then with the h;=K&n typhoon intake. We will be recording AFR's the whole time.

Link to the intake I bought and dyno charts:
http://www.knfilterchargers.com/sear...rod=69-8001TWR

I’m hoping to get some real undeniable data out of this test and silence some of the 2nd hand opinions that get thrown around on nasioc.

My expectations:

The K&N Typhoon will give me little to no power gain down low, and 3-5 whp at top. Because in intake tube diameter is the same as stock, and because this intake has an air baffle, I'm expecting the AFR's to remain reasonably close to stock.

When: I got the first two dyno slots to do this: 9AM - 10:20AM. If your interested in this.. come and check it out!

so thats it! unabomber.. time to update your FAQ!

great dyno, yea i was planning on the k&N anyways

[InfamousDX]

Wow... nice gains!

[Hummer]

Thanks for the dyno!
I ordered one Sunday.

[nhluhr]

wait that's not the same dyno chart that Dan posted on his website... Also, why are the timestamps for the two runs on the chart you posted within a minute of each other?

Which one is correct, yours or this one:

[AaronWRX]

They are both correct. I did 6 pulls that day. I have the dynojet software and the raw files so i picked the highest number from stock and compared it to the highest run with the intake. I think thats a better comparison. All the runs are pretty close +- 1-3 If anyone wants all of my raw dynojet files PM me.

[02WRX_BLUE]

Did you reset your ECU after installing K&N intake? That is the reason why you saw a gain if boost and AFR did not change! At the time of run, the timing was more aggressive IMHO.

[AaronWRX]

The ecu was reset. paypal me some $$ and I can test your theory.

[Unabomber]

Thanks for the testing! That's called taking one for the team and I appreciate it. I did add your results to the intake thread alongside Nick's. I just wonder if the gains are/would be identical for a WRX. Hmmmmm....I should be up at Mach V on the dyno later this month.....

[scooby24]

Do you think this will silence the mod nazi's who think intakes don't do anything for our cars...

Doubt it. I'm going to be placing my order for the K&N soon. Where did you get yours and how much did it cost? Lowest I've seen was around 230.

He reset the ECU...don't go around calling people nazis...

Reset your own, and you feel the power increase (without changing any parts).

For a more accurate result, he should:
1.) Put on the K&N Typhoon
2.) Reset ECU
3.) Drive like he normally drives for a week
4.) Go to the Dyno.

[CBRDSpeedfactory]

have the K&N intake... we are talking the one with the heat shield right? with the red wrinkle coat.

I also ran a 2.5" hose from the lower inlet on the passenger side, into the air where the filter is.

We do this on all of our cars, to get a fresh air flow on the highway. I have logged IAT's on the audi before and saw a nice drop in temps.

The problem with the kit is, u can't use it with anyone's FMIC and such...which is why our TMIC water/air is going to use the stock plumbing points.

I agree though, K&N builds a great product...even the clamps are nice, with allen head bolts and such.

[stihopeful]

would it be possible to fit a fmic if you removed the heat sheild and did some custom pipe bending

The first skeptic.

I do reset my own and I feel less power, as is with most cars. ECU slowly builds up timing until it finds the safest levels. It doesn't Start high and go low...that wouldn't make any sense.

Also, it doesn't take a week for the ECU to learn..usually more like 30 miles. Other people have dyno'd this intake and they all seem to get the same results.

I had the GPmoto shorty on my WRX and it gave power. Butt Dyno said so

[dsmperformance]

Anyone using this intake with a Cobb AccessPORT tuned STi? Just curious to see the AFR's with a AP reflashed STi.

All the environmental variables now have changed. How is this more accurate?

[STi-MAN]

yup, hahah ive seen more dynos where this made power then where it lost it so, for me it works.

[particleeffect]

how is anything accurate enough when the stock ECU has SO much authority over timing. that's my problem, it's not that i'm saying the stock intake can't be improved upon, it's just that the ECU is so flaky. you might have more power one run and get the slightest knock and be stock or lower the next.

-edit, so what i mean, is that i just feel like nothing on this car is consistent unless you retune. even if you can flow more air with a new intake.

[quote=soso3 Reset your own, and you feel the power increase (without changing any parts).QUOTE]

You say it gets more power after the ecu reset? How does it do this? So then it must put all the timing into it that it can, then sences knock and starts pulling timing, I don't think it works that way.

It looks to me like it made more power with the intake (despite how this whole nasioc belives that intakes make no difference on this car). Yeah i guess you could say that the ecu messed with timing during all the runs so you can't compare them right? Well what happens if there is a small pocket of real dence air that happens to come floating by the car during the dyno and makes the one run read higher? I mean, that could happen right?

Looks like pretty close to the same gains k&n got when they dyno'd the intake

[totoherbs]

Too funny.... yes, we are all against them; not one person uses them; we are all just crazy loons. Its not like we know how the ecu works or anything.

Ps. Think again.

then it must put all the timing into it that it can, then sences knock and starts pulling timing, I don't think it works that way.

Thanks for posting that. You've just help prove the power of the K&N. According to Shiv the ignition advance multiplier goes to its lowest setting after an ECU reset which would mean any gains right after an ECU reset would be caused due to an aftermarket part being installed. Once the ECU detects any knock at all it begins decreasing the multiplier.

What this means: the 12 hp gain after resetting is all intake. If the power was causing it to run lean or detonate the ECU would pull timing and that 12 hp gain would not be reproducable but it was which means that 12hp gain is safely achieved.

Thanks bud

Ok...dyno it again in a week (or 30 miles, whatever) and see if the ECU has learned around the new intake.

I never said the K&N doesn't help - I had one in my WRX and it seemed to smooth out the power band.

The temp/humidity is going to be different, yes. But it changes every day. You're never going to get the same numbers on a cool day as a hot day with the same setup. What's your point? Are you only going to drive when the conditions are the same as the day you did your dyno run so that you can say "I have +12 HP today!"

[totoherbs]

Yes... after you account for the IAM setting giving you a 10 to 20hp gain. So... um. The 12 hp gain may in fact come from the setting and not the intake. The ecu pulls timeing after a knock event... intakes do not cause knock. The just dont do much.

it's less likely on the dyno... unfortunately, most people drive their cars in the real world where it is much more likely.

[kedrin]

dyno sheets can be biased.....


ever seen a car pull a low hp on the dyno only to make better power the next run?

im not saying that this is the case but one could easily take the lowest pulled run and compare it with the highest pulled run with the intake.

If it is legit i give it 3 thumbs up
