No, you blow me, asshat!

Any progress made lately?

[JTDahl]

Excited to see the results of the other intakes.

[Taskmaster]

Yeah, I have to email/paypal a member later this week to get a hold of the AFE SI intake for the test. To be honest, I fully expect the Injen to win, I just think it looks terrible.

I'm also going to try and rig up a custom intake from the extra stock box I have (AFTER TESTING) and see what I can come up with.

i stumbled upon this thread...some interesting points about the injen compared to sealed intakes

[Rival]

i copied DJ APEX's euro intake, and honest, it pulls a tad hard in the upper rpm's.

after the little dip we get at 3.5/4k it feels better. nothing crazy, i bet it did knock a tenth or two from the 1/4 mile time tho.

buy a stock air box and try it. or shoot buy the parts and ill build it.

That was a very interesting thread!

[Taskmaster]

Talked to Johnny D, should be getting the SI intake this week, and I talked to the shop to get some dyno time in. I hope I can do it all in about an hour or so, but if anyone wants to pitch in for dyno time - you can paypal me

mr_ice15@yahoo.com dyno time is going to be $85/hr.

It will be baseline - stock intake with OE tune

Stock intake box with carbon filter removed dryflow filter and OE tune

Injen Intake

AFE Intake box

Hoping for Thurday-Saturday to get this done, comments are always welcome.

It's ok to be wrong (which you are) Test like these matter less on a turbo car because the intake doesn't have to be tuned (it's pressurized.)
Thanks again for the non input.

okay this is a stupid question but when you say "the intake doesnt hae to be tuned" you.re talking about your OE tune or my AA tune right?

No, normally intakes are actually (or should be) "tuned" to a car through tube lengths and diameters.

True before variable valve timing.

[mike-y]

well, to be fair, he didn't say intakes didn't work on turbo cars, only that tuning the intake lengths wasn't as important on a forced induction car vs an NA car.

on an NA car, intake length and diameter can make a huge difference because of resonance. when I had my integra, an CAI (long tube) picked up 9whp on top and 11whp in the midrange where the resonant frequency made for a nice torque bump at around 3400 rpm. a short tube intake made close to the same high end power, but didn't make any more midrange power, and actually lost a bit of low end torque.

Taking advantage of resonant frequencies will increase power on NA cars. This is also how the 3 stage IM works on our cars with the disa valves.

On a turbo car, you'll see a lot less variation because once the turbo spools up, it's almost all about flow, not resonance or tube length.

I didn't want to get into it, but thanks for explaining it for him.

[JTDahl]

I don't understand all the hate, Axiom understands that the intakes aren't going to make huge gains but he is just trying to find out which one is better than the next. If nothing else it will just be more information. If its not on your dollar then there is no need to worry about it. Props to him.

[Johnny D]

I was and still am skeptical about the test. However, the thread starter is so adamant about doing a comparison test and it could potentially finally show definitive proof that these intakes vary little from the stock box. I felt it would be beneficial for me to donate to the project. My aFe intake goes out tomorrow to him for testing. Should be interesting.

It's hard for me to imagine spending thousands for 10-15hp when you can buy a turbo platform and EASILY make power. Go drive a 400hp STI or Evo and you'll realize how stupid it is to waste so much money on these cars. It will never be fast. It's not meant to be. All the mods in the world won't even get it close to a stock 335.

why is it so hard to understand that we like NA motors but want to squeeze some power out if we can... if i really wanted speed brb 2k honda hatch brb 4k blower gg

you're not telling us anything we dont already know. I just happen to make money while at school and enjoy pissing it away on my car. I know i could have bought a miata, FI'd it, tracked it out, and been faster around a track than any of the cars you said for just a bit more than what I spent in aftermarket and maintenance on my N52 car. I even thought about that for a while and decided against it. But I dont really care. Its my money and i can spend it how i please.. and have you ever taken your mazda to the dragon or similar twisty mountain roads? i can almost guarantee there are several members on here that would be faster through those roads or a tight track than you when you show up putting stupid horsepower through the front wheels. It seems weird saying that our cars werent made to be fast while at the same time claiming a car built to be an corolla competitor is a better option for speed.

[Taskmaster]

I think everyone understands that we won't see the same gains as a turbocharged motor, but the gains seen from these motors what I would call more than "reasonable" including a few dynos showing gains over 30WHP with bolt ons, and a member here with over 240whp - contrary to your claims otherwise. (You could have easily checked the link in my signature)

And while you berate people who want to mod their car, essentially telling them that is a pointless endeavor to pursue on our platform, one of your previous post advocated buying a 335 for the same reasons - huh?

the time is almost near..interested to see the results!

My air box hits his door tomorrow.

Tomorrow at 3pm. I'm going to swapping these as fast as possible and see what we come up with.
