Default K&N Typhoon, great product, Dyno proven.

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...)

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

Iím 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!

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:

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.

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.

ahem!! i'm right here... There is no need to speculate on what I did or didn't do. If you want to know if I did the ECU reset trick... ask me!

Let's define the ECU reset trick...

"With the car fully warmed up, reset the ECU. ...... Push the go pedal down slightly so boost stays right around 2-4psi. You will need to MAINTAIN 2500rpm and 2-5psi for approx 5 seconds. You can do this by left-foot braking gently as to prevent acceleration."


Now what sane person would think that I would spend my $$ on this product, and dyno time, only to fake myself out with the ecu reset trick? What sane person thinks that K&N R&D read the shiv thread and did the ecu reset trick to inflate their numbers?

Do I work for K&N? Hell no!
Did I do the Ecu reset trick? Hell no, that would have been totally asinine!
Do I have ANY reason to talk up their product? Hell no!
Was I surprised by the results? Hell yes!
Do I wish more Nasiocer's would put up or shut up? HELL YA!

This was done at Mid-A's monthly dyno day event... it wasnt just me and the dyno operator cooking up numbers to sell more K&N's. There were ton's of other Mid-A'ers their to watch ....


My advice to the next guy who tries to provide real data to nasioc... even if the instructions say, "pull the negative battery terminal to avoid damage to you MAF sensor..." ignore that so you can make sure your ECU doesnt reset. If you do that, EVERYONE will be happy and much more accepting of your data.

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.....

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.

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

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

[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

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

I've swapped back and forth from stock to my APS 65mm intake twice, and feel confident that it does help. I switched back to help Trey at cobb troubleshoot an issue with the fact that i was seeing high EGT's on the new base map. just yesterday i put the aps back in, reset the use, and it felt noticeably better/stronger. I only expect that power to increase as the ecu relearns fuel.

The ECU shouldn't need to relearn fuel if the intake is properly designed as the ECU will get the same amount of air for the same MAF readings. This is what the K&N Typhoon appears to do.

You should be able to swap back and forth without any problems or learning required, the only difference will be increased power.

I thought that the APS 65mm was one of the good intakes that acted like the stock intake?

Default I also..

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.

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.
