Tested: Ebay Filter

I just installed my Ebay filter with a custom cold air box (read an 8x8x8" cardboard box from UPS). With my Forge RS BOV, it sounds like a freakin' VTA BOV
Now people are going to think I'm a ricer
We'll see what Bryan thinks of my set-up when he tunes it this Saturday.

The test is here to show that Ebay filter will not throw off MAF anf you will stay in correct load columns. I guess it does look like it runs richer, although it did not make much difference in AFR's for me for some reason. It's NOT a test to show that "Ebay filter makes power for anybody"

NJ,
I know that your intake temps weren't that high, but it just dawned on me that in the 2g ECU timing would get pulled for certain coolant temps and certain intake temps.
For example, 1 * of timing would be pulled for coolant temps >206*F and 2* would be pulled for > 224*F.
For intake temperatures, it is as follows (from the DSMLink creators):
"Intake temperature will also cause a reduction in ignition advance. The tables are laid out like so, with interpolation occuring between the points.
2G intake air temp ignition advance adjustment:
185F = -3°
132F = -2°
100F = -1°
73F = 0
48F = 0
20F = -1°
-23F = -2°
1G intake air temp ignition advance adjustment:
185F = -3°
132F = -1°
100F = 0
73F = 0
48F = 0
20F = -1°
-23F = -2°
"
So, if the Evo ECU uses the same logic (not sure if this portion has been disassembled), then 1 degree of timing can be pulled if the intake temps reach 100*F with interpolation between 73-100*F , or whatever value the Evo ECU uses.
So, this may explain some of the lower timing numbers from an open cone intake. As IAT approaches a certain value, the ECU will begin to pull timing. I think the ECU can work in fractions of degrees, too, but our loggers just display whole numbers. So, it would be easy to see a 1* timing change in our loggers if the IAT increased passed this value.

Here in CA, it is dangerous to have a loud car. With all the reading about crackdowns by the police on modded cars, I made the decision to remove my ebay filter and go back to stock. The small hp gain and the high IAT made the decision acceptable.
I swapped out my boost lines and installed the boost lines with the #65 pill. I started messing with the boost today. My aim is 21 psi @ peak and holding to 20 psi all the way to cutoff on 91 pisstane.

I know what you mean. This thing gets loud whenever you cross 3000 rpm @ about 50% throttle. It and it gets even louder as the rpms climb.

I'll stick with my K&N dropin panel, thanx.

Anybody thought about mounting this thing in the stock airbox? I was thinking that a cone filter in the stock airbox and maybe cut a rectangular hole and mount panel filter like KN drop in? I realize others have put a cone filter in an airbox I wonder what the results are/were? The box would serve to keep IAT down along with noise.
If I run a conical filter in the airbox of my wifes Audi it is definitely quieter than w/o airbox and cone filter but it is still too loud for my wife (noisier due to more flow than panel filter?) As far as power is concerned with and without box I do not know how much difference (if any) there is as I do not log her car. Seat of the pants you can't really tell.
The fact the AFR's change does indicate more flow via ebay/conical filter as the maf sensor reads more airflow and adjusts fueling right?

All you need is a cardboard box from UPS. Cut it to fit. That is my new "cold air" set-up. I kept the top part of the airbox and painted the cardboard box black. It looks stock when you pop the hood. You get air from the stock ram-air set-up and you go to Home Depot to get some tubing to direct cold air to the underside of the box.
I should really take pics. Razorlab will see this inexpensive set-up on Saturday. I can't claim the idea to be my own, though. WOT showed me his idea...then again, he's the one who has built CART, IRL and other engines for a living

I have had on my to do list to fab a cold air intake.
I got my idea from here.
