why doesn't everyone that wants the car to be dynoed again......paypal Aaronwrx the money?.....i think he's done great service to everyone already.

With all this skepticism and negativity towards the dyno results of the Intake, how can you say ANYTHING gives more power?

"I just put on my Catless up-pipe, TBE, and Header and I dynoed 40 hp more"

Skeptic: "No you didn't get ANY power its all the ECU fluctuation. At best I'd say you got 10 hp"

give me a break people.

I had a short ram intake on my stage 2 WRX and consistenly ran 2/10ths of a second faster with it than I did without it. yes that's right...CONSISTENTLY...meaning ECU re-learned. 60' times the same, track conditions the same.

Just admit for once your guys' stereotypes of the intakes just MIGHT be wrong.

If we're not going to spend money on an intake, why would we pay someone else to do another dyno run?

Intakes are the debbil!!!!!!!!!

Did the intake make the 12whp? Or did the reflash trick that has been known to give 10-20hp higher readings on the dyno do it?

You cant and you shouldnt... maybe if you pulled the motor off and put it on a engine dyno. Chassis dyno are designed to help you tune the car and not measure exact power. http://www.pumaracing.co.uk/power3.htm

All some of us are saying is think and dont blindly belive a print out. Some of you take it as a personal atack.

I have to say I put this intake on my STI and coupled with a downpipe (no ecu reset) I made 249 horsepower and 240 torque when stock cars are on a mustang dyno stock cars make 220s. You can feel that the car breathes better up top, like it opens it up a bit, even when that was the only mod I had.

Just think about what has physically changed with an intake upgrade. We went from a plastic tube to an aluminum one (which may be a bit smoother). And the filter will have less restriction. But if people are saying 12 whp, that might be 15-16 hp at the crank? Now think about it, isn't that a bit much for this small of a change?? A smoother intake tube isn't that big a deal here, intake air velocity isn't all that high. Unfortunately the ECU response does confuse dyno results and they do need to be questioned.

Its not just less restriction on the filter (which is a larger change than you'd imagine), its also an increase of filter surface area

The more air running to the engine the more power it makes. It's a simple theory.

My old car (nissan 200sx se-r) had a similar setup for intake. I dynoed a baseline and then added Hotshot intake. Got 8hp at the wheels. This was a car that is very steady on the ECU and didn't fluctuate power easily. Why wouldn't it make sense that a TURBO car would make 4 more hp at the wheels?

Open up the filter, make the pipe length shorter, remove the silencer, yeah it's gonna make more power. It's not hard to figure out.

you guys can speculate all day long, but the facts are that there are two dyno sheets above showing a gain in HP from an intake change. if you guys want to argue that point, prove your side. until you come with evidence (not opinion) then your argument is junk.

Prove your side...? I have yet to see proof of anything. Well maybe another confirmation that shivs reset trick works.

Do we even know they did the reset trick? How do we know the reset trick works on the STi ECU?

I've been running the K&N for 7,000 miles now, and am very pleased with it. 12whp? I dunno.....wouldn't surprise me, but I'm happy with it in any event. Car felt like it breathed better up top, 5th felt more responsive immediately (I thought I must've been in fourth, honestly, the first time I took her out after the install), and when I got my UTEC in my AFR's were rock solid throughout the RPM band. I've nary a complaint.....and feel it was a solid purchase.

I believe it DOES NOT work. I have yet to see concrete proof otherwise.

is pulling the neg battery terminal (resetting the ecu) and shivs 10-20whp ecu / reset trick the same thing? it's common law to reset your ecu after doing a mod, so by theory a 20whp gain from a turboback is only worth... nothing?

Exactly. Their arguements are pointless.

Okay, here's my blow-by-blow of the intake install.

Dyno STi, three pulls.

Aaron & Dan and others dink with intake install for a bit. Battery is disconnected during this (as is prudent during any install).

Dyno STi again, three more pulls. All three are higher by 12-13 hp than the first three.

There was no fancy 2600-rpm reset trick done. There was no other trickery or adjustments done. The whole process was witnessed by many bystanders. Assuming that the car actually starts out at only 8 degrees of timing after a cold ECU restart, and then slowly regains its normal timing, it should have been DOWN on power (all other things being equal) after the power being disconnected.

If the graph above doesn't sway you, well, I don't know what to tell you. But I didn't sell this intake before, and now I do, because it looks to me like a pretty clear gain.

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.

See there you guys go thinking its some personal atack... crap life must be hard for you; when every time someone disagrees with you you think its an atack.

We will just have to agree to dissagree on intakes.
