It's a very dusty area here, so I'm afraid of using AFE drop-ins, because I'm not sure about their filtration ability... Or maybe they are good at filtering?

any thoughts about the AFE drop-ins? are they good at filtering?

p.s. I also thought about heat shielding stock airboxes, so it would be nice to know if it makes sense

Why do you guys feel the need to heat shield plastic air boxes that keep iat's far lower than shielded g3s?

AFE dryflows are what i had, they are great filters that do just as well as K&N...

Have you taken the temps of the airboxes while the car was sitting? If so, what were they? Have you taken temps of around town driving? If so, what were they? Have you taken ANY temps of the airboxes at all? If so ... what were they? Every degree cooler is going to result in power, if only by a marginal amount.

That's because, on a 90 degree day, sitting at a redlight for a few minutes, your IAT's may rise to 150 degrees or more.

A quote from Modshack above... 150 degrees or more... now why would heat shielding help with that Zed? Hmmmm, doesn't seem to take a rocket scientist does it?

Red__Zed · 10-20-2011, 11:13 AM

Maybe that's why I'm struggling with it...i am only qualified for rocket science.

Iirc, what Steve is talking about there is the reason for ducting. Heat transfer through the plastic is small, but you are picking up hot air at the inlet. Shielding won't help with that.

that is why I asked you if you have checked the temps in the boxes at any time... if not, and no one else can chime in then it's all speculation. If one wants power off the line as well as power into higher speeds then everything has to be kept as cool as possible.

Red__Zed · 10-20-2011, 11:35 AM

Yes, I have. My data logs were posted, but the thread was removed after I was accused of being a z hater for posting iat temps. If I have time, I will pull them up and pm you.

Long story short, you suck in hot air. The tuning wall does not heat up on the interior even after reasonable time idling (obviously at 15 minutes plus, everything is heat soaked). Even them, I speculate that it's primarily due to hot air coming in.

Post maf tubes that were notably better insulators saw mild improvements, but not as
Much as youd expect given the extra insulation, lending credence to that theory.

Methodical4u · 10-20-2011, 11:55 AM

well post them up... I don't care if you're a Z hater or not personally.

I agreed not to post any more data logs. It's not worth the trouble it brings, and I'm not gonna hassle myself to help a community that won't help itself.

My computer with all my data is still in storage, but I will pm docs when I have them out again.

Red__Zed · 10-20-2011, 11:59 AM

I have dragon run diff and brake temps for a bunch of cars as well if you want those.

Were you taking measurements of everyone's cars at ZDayZ?

Red__Zed · 10-20-2011, 12:04 PM

Yes
