JE Custom Intake Manifold, CAI, etc
Well, after months of design and testing... it is what it is. JE designed an intake manifold and modified an Injen CAI to go with it. After some gains with the first design, they thought a smaller plenum and longer runners would yield more power... alas, it lost power so we put the 1st version back on and called it a day. The attached dyno also includes the NST pulley and my (now quieter) 2.5 custom stainless exhaust. As the numbers were a little dissapointing, my guess is that the mani will not go into production. I had planned to have them also do custom long-tube headers and catless dp but (which, in a Lotus they did, produced nearly 15hp)... but my BMW 1M will be here in a couple of weeks and I will be spending my doe modding it instead. I'm keeping the xD (I love our little car), but as this will now be my wife's car and she couldn't care less about getting more power if it = louder, power wise, I'm done. However, my brakes are shot so I just ordered some Rotora rotors and Hawk ceramic pads.

More pics
Here's a better look at the modified Injen CAI that tucks nicely behind the bumper. A pic of the 2nd version of the mani that lost power but you can see the type of work JE can do, really great people. The exhaust, and... my new baby which I should have later this month.

You know I think I still want one. I mean it looks like it looses power above 4.9k rpm, but gains pretty good tq around 7 ftlbs at 3200. So there are gains below 5k rpm, where my daily driving maintains. Who should I talk to?
Oh, and congrats on the new car. Those are sweet!

Yeah, I was a little disappointed but, I guess a little down low is better than nothing. Maybe this is why no one has made a mani for our xD, not an easy task. You should talk to James if you're interested, he's the owner. And thanks, really excited about the baby-M - already got a full sponsorship from CP-E and if I take delivery on schedule, we're hoping to have the first modded 1M and hopefully that'll mean some more sponsors before press... we'll see... I'm sure plenty of other guys have the same idea.

Mmmm, I'll think on it... I paid a boat-load for it...I'm almost embarrassed to say how much.
James says that NA cars typically do better with a smaller plenum but longer runners (bigger plenum for turbo cars). With our car there's not much room to play with runners so the 2nd version used longer but folded runners. But, for whatever reason, it lost power so it was scrapped. After flogging it while doing some errands today, one thing I noticed is that the new mani was really hot, maybe that's normal but I just checked it an hour later, still really hot... wonder if heat is an issue. I don't know, I only know what I read in car mags and forums... and only understand about half of that!

sorry to hear that dude. but atlas you have a nice beamer coming 
. But thats without a tune right? if you ever consider selling it. Let me know. Maybe we can work something out. I will try to continue modding this little box and still give the 2zr some hope

True dat! And all though I probably won't mod my xD much more, I do love it and will keep checking in now and then. (I'm "Ohcrap" on 1-Addicts too !)

Well, I've been communicating with James Evans from JE, and here's what he said.
Hello, I took a look at the thread and figured I would let you guys know that your comparing the wrong runs. The run showing the high top end gain is the new manifold. Which is why this manifold would be well suited for turbo. The lower more rounded dyno plot was the stock manifold. The gains were all on the top end with this setup. It would be nice to test one more design change that we have, but I would want to try this on a manual trans and not the auto. I think this AT setup is skewing the number a little. I think it could be mass produced for under $1000, but we would have to make ten or more to make it that cheap. We, "JE" do a lot of R&D and testing for a company called "Sikky", these guys would be the ones mass producing these manifolds should they decide to. I think they would probably want to test this final design change first before doing so and it would need to be on an automatic. We would have to find someone local to maryland willing to buy this manifold and offer up there car for a before and after dyno comparison. If this goes well, it could go into production but based on the gains this current manifold would really be sold and marketed as a turbo manifold. That is very interesting that the manifold is listed as the same part as those other cars. I had no idea. If it could be sold to them as well it might convince the powers that be at Sikky to invest some more time and money into it. Steve was kind enough to put up some money initially to build this manifold, but our combined design time and CNC time is ten times what steve has in it. Which is why we are at a crossroads if we want to try one more time, who knows....as they say, third times a charm?

I want one, but it looks like we need another good soul to step forward from Maryland. If this product could be marketed to other vehicles with the same manifold I'm sure we could secure 10+ people(1.8 Corolla, Matrix, XD, Pontiac Vibe). So is any one game?

but anything that could potentially give the xD more parts and powuh is fine by me.
