Dejon Tools intake size and FIPK fitment?

[Bluedragondsm]

Ordering a Dejon tools intake pipe and was curious how it fit with a FIPK or if it was a better idea to order the generic one they suggest. Would prefer FIPK due to its flush fitment and larger surface area.

Also which of the 2 dejon intakes would be the best choice for a current T-25 with plans to go no bigger then a EVO III 16g.

CIP-2gSx- 2.7" & 3" - $140 (NO tubes)
CIP-2gSx- 3.5" & 4" - $150 (NO tubes)

I am assuming the 2.7'' & 3'' will be the correct choice.

Also when they say NO tubes or BOV tube only, are they reffering to a replacement stock tube or do they have some issue with the stock BOV return tube not fitting properly and require a special tube. I am fairly certain they are just reffering to a replacement stock BOV tube but better safe then sorry

I would steer you away from the dejon intake. They're steel, and they're heavy. Get the FP intake and be done.

FP intake doesn't come with vacuum holes, and I don't really have the know how to tap them.

You drill a hole with the right sized drill bit, and thread it with the right sized tap.

It really is, as simple as that.

Where does the FP intake place the MAS? any pics of it with a FIPK in a 2g

Are we all convinced that the FP intake will be the most efficient for a T25 to evo316g setup?

Dejon 2.75" inlet pipe comes with a BOV if you purchase that option. It requires 3 things to fit/function properly: 1) Chop ~1" off the BOV return tube since its way too long. 2) Purchase a high quality 2.75" to 2.25" silicone reducer coupler transition. 3) Buy some snazzy T-bolt clamps for that cool high tech look. Then enjoy having a very nice looking intake on the car.

The FP 4" intake doesn't belong on a 16g and it'll cost you horsepower due to a highly turbulent 4" to 2.25" reducer coupler. The Injen/Ebay 3" aluminum intakes flow the best of any intake I've tested, but they have to be chopped in half, then remove about 0.75-1" out of the midsection, then rewelded or hose clamped for a proper MAS positioning.

Please source your CFD showing that. No matter what intake you use, the air entering a turbo will be pretty freakin turbulent.

Your making a generalization. Sure, I can source my own CFD analysis. To what extent the airflow is turbulent depends on the intake design. I did extensive CFD analysis and used a venturi tube design as the control, as this is the best intake you could ever slap onto a reduce inlet device. The 4 designs I tested were: RRE 2.25" intake elbow, Injen 3" aluminum intake, Dejon 2.75" intake, FP 4" intake w/2.25" coupler. I predicted based on the pressure loss differentials that the Injen would outgun the FP4" by 16 h.p., and see below for the results.

Having said all that, I also road tested each design, then logged the ECMLink calculated h.p. on the same stretch of road. As a control, I dynoed 384 w.h.p. on AMS's dynojet with the RRE 2.25" elbow. ECMLink backed it up with a 386 w.h.p. or there abouts. The results I posted elsewhere, but in short the Injen was consistently laying down about 404-406 w.h.p. via ECMLink. The Dejon was around 402 w.h.p. dead consistent on many back to back pulls. The FP 4" was boringly consistent with 389-390 w.h.p. and not an ounce more no matter how much boost I ran.

So, which do I run. I run an Injen/Ebay knockoff I cut in half so I could port it and make it fit better in the stock MAF location. It makes better high rpm power, and in fact enough that there is still some room to crank the boost up higher and gain from it. The FP didn't like the high boost and in fact higher boost levels had no affect on power. This is why I don't run it.

Thanks for posting, pboglio. I was hoping I could catch your attention.

So dejon is the best option with a 16g unless you want to cut and weld?

ebay injen copy. just change the coupler that connects to compressor housing.

fraction of the cost compared to dejon/any other

I don't want to Cramp up your thread with my own questions but i didnt want to start another and not get any replies. So on a 1gb What about the Bullseye-Power 3" Inch Intake Pipe? how is this rated?

You would still have to cut it to retain stock MAS position which is a big deal to me.

If you buy the Dejon Tool intake pipe, you'll really want one of these: Transition Hose 2.25" to 2.75" - silicone : atpturbo.com

The transition is what makes or breaks all the intakes. Ideally you'd want a transition hose with about a 15-30* angle at most, but this guy will work well enough. The 2.75" silicone hose Dejon gives you is a catastrophe, chuck it in a drawer. Going from a 2.75" to 4" diameter makes no difference on any of the intakes, its all in the little transition leading to the turbo inlet. Sweat the details here and you'll be rewarded.

Well like you said the dejon provides more HP and I never plan to go bigger then a 16g, at least not for a few years, hell staying with the t-25 for a year at least.

Dejon provides the most bolt on solution with the best MAS positioning, other options need modifications for all of them.

DEJON | Powerhouse

CIP-2gSx- 2.7" & 3" - $140 (NO tubes)

and those couplers would be my best option?
