thanks for the dyno sheets

i was looking at
Filtration Testing for Amsoil, K&N, Napa, Jackson Racing, Baldwin, and Mazda air filters on a Miata

Its all fine and dandy but was there a stock air filter test? Does the stock setup let in just as much crap as k&n?

i spoken with K&N today when i picked up my car. seems like they are also developing new air filters for the Z because they told me that the filters weren't getting enough air through.

EPIC fail on their part.

Ah DUDE! I wanted a drop in filter....... Those arent out yet right?

But HP is just torque multiplied by RPM and a constant, so you could recreate the torque curve if you really wanted. Typically dynos *only* measure the torque and the HP curve is created from that.

Kind of weird not to see both though.

Yeah, they're out. You can find them on K&N's website, and I have them in my car right now. RCZ tested them and found no gain, however. (Which is why in a few hours I'll be taking the entire stock intake system out of my car and installing the Stillen G3 intake.)

No, you dont want a drop in K&N filter. Almost every time, they have proven to be worthless.

do u have picture of ur k&n intake?

Hmmm...I have my reservations about using K&N cold air intakes. On my SRT4 the dang silicon elbow would collapse and choke the turbo beyond 15psi. Took weeks to figure out what the heck was going on.

That's just me, your mileage may vary.

Hello, my name is Reina Gamez and I work for K&N in the R&D department. Right now we are in the process of developing an intake kit for the 370z, so if you live in or around Riverside, CA and would be interested in receiving a free intake kit, you can reach me either by email at reinag@knfilters.com or call me at 951-826-4000 ext. 4458.
Thanks

Now that I have your attention I will explain why, My last vehicle was a 2004 F-250 power stroke diesel 4x4 lariat crew cab. I had exhaust and a programmer and an AFI intake this was a 6.0 (the one that gets the bad wrap for reasons which do not relate to this post). Ok now my truck dyno'ed after being custom tuned at 450 horsepower and 670 lbs. ft. I never went to the track but my friend with the same truck and tunes ran low 13's pretty crazy for an 8,000lb truck but do some research you will see I am not lying these trucks can cut 1.8 60 foot times easy we simply put it in 4wd HI and brake boost to about 20 pounds of boost and I can out launch anything on the streets (my truck maxed its boost out at about 36 pounds)

Now that you have the history of my truck here is the deal I am a member of a powerstroke forum and I can give you links to at least 10 people who have "dusted" their engine and turbo by using a K&N filter. Dusted means dirt and particles got past the so called "filter" and sand blasted the turbo and engine. I can also give you several pictures if y'all want

I realize this is on a FI application so it is pulling in a ton more air, but it still leads to the point that K&N filters dont filter the air near as good as they claim. I just want to inform people of this because I would hate to see more people getting "dusted"

dude, u do realize that u gotta oil the filter after u clean it, that's if u ever cleaned it before

They're talking about new filters for the stock boxes I believe. Stillen uses a completely different shape, so that's unrelated.
