Updates!







So the filter lives in that round box, and while there is a hole in the center of the lid, I'm thinking about moving the elbow to the edge of the lid so the bend isn't sooo ridiculous. It's really tight and I'm trying to not have to get a new airbox. I'll get more pics up one I feel motivated to actually manually upload things vs using facebook. My phone decided it no longer wanted to take pictures today... So I can't just quickly upload them, haha.

Steve, I checked out that part number, those look perfect for both the fuel cell and this!

But yeah, I quite GutterMaxx in July I think it was, as corporate has their head up there ass. I had a 29.5 percent closing average, most deals on the board, and they were mad because I didn't have enough cancellations. I had one.

Note the "NOT ENOUGH" part. WTF? They want me to push harder? No thanks, happily in the front of the pack, not about to turn into uber douche salesman.

No, not really. I can run leads for my buddy if I want to, but I quit the corporate retardation awhile ago. My main sources of income now-a-days are Timm Von Derau - the photographer, and Seattle Photography Lessons.

Dad dug out an airbox from a suby or mitsubishi last time he was at the pull a part, it fits so well behind the right headlight, you'd think it was stock! That's what'll hold the filter, and then I'll have a little elbow connecting the two. I'll take some pictures. The guy I was supposed to be teaching right now rescheduled, so I have time!

Teaching someone? You? Does it involve small farm animals?

Coming from the guy that live in BFE.... We should be checking YOUR place for disturbed animals.

I run Seattle Photography Lessons. I teach Photography and Post Production on Adobe Photoshop/Lightroom and Apple Aperture.

Oh...Apple aperture...I knew it would be something kinky... "he, he...he said aperture "(think Butthead voice here)

did you make the carbon fiber ends? curious why you didnt make it a single piece.

I did. It was easier to go to world market and find a bowl of roughly the right size (diameter, nailed it, unfortunately, the inside of the bowl wasn't a perfect sphere like the outside (save of course for the little "foot") was) to use as a mold for the end pieces, vs make a full mold.

Plus, I knew how the back end would be, but the front, due to the inlet, I'm not yet entirely sure where things are going yet.]]> Dazed_Driver Construction Zone Mon, 09 Jan 2012 12:14:34 -0600 https://www.rallyanarchy.com/phorum/read.php?5,59857,59902#msg-59902 Re: I guess I'll share with the class, ITB plenum https://www.rallyanarchy.com/phorum/read.php?5,59857,59902#msg-59902

I've still gotta figure out how I'm going to actually attach the two halves together, I'm thinking those little flip clip things (like what on an airbox). I also need to get some thin weatherstripping or maybe foam rubber to make a seal.

When I built the cold air box for my friend's EG33-powered Impreza, I used stock WRX air box clips...he had them around and they were free. Kids toss the stock airboxes all the time.

Did you do any calculations to figure out what volume your plenum needed to be? It looks pretty big.

The runner length and plenum volume work together to generate a resonant frequency which can enhance airflow. So, you typically design the runner length, runner diameter, and plenum volume to tune for a specific engine speed to enhance torque. Since your runner length and diameter are already fixed by using an off the shelf part, you should make sure the plenum volume is in the correct range to enhance these already fixed variables.

See page 23 and beyond in here:

Yeah, I did. I have a page somewhere bookmarked breaking down the equations, which they got out of a motorcycle tuning book. I've also got another pdf somewhere that is a college dissertation on WRC airboxes (what are the odds, right?) for the Celica, it's like 100+ pages of info.

That airbox is actually slightly smaller than I would have liked, due to size constraints :/ oh well. Maybe version 2.0 will be bigger :D

EDIT: SKimmed that ppp. Interesting read. I'll have to compare it more to the two sources I used to see where they all differ, and what's the same when I have more time. Maybe I'm right on the money?]]> Dazed_Driver Construction Zone Mon, 09 Jan 2012 11:02:06 -0600 https://www.rallyanarchy.com/phorum/read.php?5,59857,59892#msg-59892 Re: I guess I'll share with the class, ITB plenum https://www.rallyanarchy.com/phorum/read.php?5,59857,59892#msg-59892 alkun Construction Zone Mon, 09 Jan 2012 10:57:11 -0600 https://www.rallyanarchy.com/phorum/read.php?5,59857,59886#msg-59886 Re: I guess I'll share with the class, ITB plenum https://www.rallyanarchy.com/phorum/read.php?5,59857,59886#msg-59886
