Bump?

 

Just to update this thread......I've had the intake on the car for about two weeks now.

The car sounds incredible and I didn't have to change my tune at all. Its a tad bit leaner up top but not enough to require a tune.

The car's idle is unchanged and I haven't popped any codes at all.

I didn't notice any gain or loss in power .....but the sound.... wow.... Definately a great purchase.

 

What i have found with aftermarket cone intakes is that the MAF readings are very much more jumpy which could affect tunning and drivabililty. But b/c of the more air getting to the engine you will get more power when TUNED right. not to sure how the Xede works but im sure its something like the Utec, watch your maf readings when doing a data log run and you'll see what im talking about. For the most part, when supporting little mods you usually wont see a gain or loss, but i've heard of people gaining on top and losing a little on the bottom end

 

Jeff,

I was in your boat also. I was hard-core to the stock airbox because people said it was better than intakes. Smoother, easier to tune etc. I'm an engineer and have good faith in mitsubishi designing the intake sytem. The stock tube is designed to work with the resonant frequencies of the incoming air etc. But at the same time I could see the benefit of some of the better designed intakes. After reviewing alot of info I was kinda leaning toward the design of the new Buschur pipe.

My car has the standard 3in exhaust, boost control and cams (264's). I had my car base flashed by DynoFlash for my mods with the stock airbox. This was not a custom tune, just a basic flash for mods. But an intake was still on my mind after the flash.

Well, I had a perfect section of 3 inch tubing sitting in my garage and I just could not stop myself from making an intake. So I did. I used a Buschur filter, and the design of the intake tube is a single 30 degree bend (roughly) just like the buschur tube.

After the first drive with the intake the sound was like music. Zero idle problems. I noticed more power. No questions, I made more power. But I was worried about "lean spots" So I hooked up a wideband. I found that in the high-mid RPMs I went from 10.8 to 11.2 and by the 6500+'s I was back to 10.8. I was too lazy to put the stock box back in and check the tune, which goes against the engineer in me, but oh well.

So the intake did indeed create a slight lean spot. Now remember my car wasn't custom tuned, so the tune might of had some variance in it to begin with. But regardless things are managable. I picked up a used AFC and am going to smooth out the tune to a 11.0 up until 6500 rpm at which point I'll let it drop down to 10.8.

I love the sound, I was fighting the whole intake thing for sooo long... but now I'm convinced. It made more power, my car used to lag behind a frineds car in the higher RPM's now it stays even with it. Only difference is the intake.

It free's up room for legit intercooler pipes also. Which I'll do down the road maybe.

 

Thanks for the reply..... I'm glad there are others the are willing to brave it a little.

 

I'm also running a cone filter on top of an XEDE based engine management set-up. The big thing is to make sure your AFR's are where they should be - some cone set-ups will throw those values off some.

My adventure started when my wife gave me a K&N Typhoon intake for Christmas a couple of years ago. After alot of testing I decided to keep the everything in the set-up except for the painted metal intake tube provided by K&N - I went back to using the OEM rubber tube. The new filter definitely breathes a bit better than the OEM airbox did and the car sounds better as well. I did end up making some minor changes to the MAF table in my XEDE to dial in the AFRs.

The XEDE is easy to tune with once you get comfortable with it.

 

After some more logging with a wideband I found that "the lean spot" was more of a user-error. I was having a friend read the A/F's off the meter while I drove. Just trying to guess at what RPM matched what A/F.

A week later I went and logged the A/F's, parked and reviewed them. I had NO lean spots. In fact I pulled fuel out everywhere to correct the A/F's to a steady 11.0 across the RPM band.

The Buschur style design with a single bend made for ZERO tuning problems for me.

 

If you have a logger, drive the car with the stock airbox for atleast 30 mins in various RPMS and vary the throttle positions. Then do 1 or 2 runs thru 3rd gear. Once you have all that logged stick the intake on and change the settings in the xede to match what you had before... Everyones cars react differently, for example when I changed my intake I actually had to lean my UTEC.

 

Interesting findings... funny how after ALL this time the debate of intake or no intake still continues.
