any gains using stock air box and new pipeing?

 

Hey guys,

Here's the dyno graph. This was done on a mostly stock EVO with HKS 272 cams, S-AFC II computer. No tuning was done in between pulls, there should be more power to be found with some tuning.

Thanks,

Gary

 

love my arc super induction box

 

does anybody know the processes of cleaning the apexi filter (instructions are in jappanese)

 

I have the Apexi kit too and I think the best way is probably take a air compressor and blow it out from the inside? If you dont want to take it apart probably use a brush and clean it since its a dry filter.

 

I kept the stock tubing and put an aem element/fitter on...cause with the hard piping, it kept coming off/getting loose with all the engine movement. sounds great the way I have it

 

i like the hks rs intake piping with k&N filters, long ones with 4 inch opening.

that would be a good combo.

 

I just installed an APS cold air setup on my '03 and it is awesome! I tried a K&N Typhoon and the performance was bad, the car would just totally lay down after about 5k.

Went back to stock with a K&N drop in. The car ran good again but I really missed the sounds of the turbo and DV.

There was a post a while back about the Evo MAF requiring the air to be hitting the MAF straight on. After installing the APS I was expecting the performance to be about the same as stock but this thing pulls a lot better, is smoother and there are no signs of surging or fuel cut at all.

The install was a little bit of a pain, the opening in the intake that the MAF registers into was just a little bit off, enough that two of the bolts couldn't be started. I had to take a dremel and do just a small amount of cleanup in the bore of the intake to make it fit correctly.

As a bonus the factory DV is pretty loud with this setup.

 

Anyone is the market for an intake? check my other post for an aem, with the newer filter that doesnt have any fitment issues.

 

I just took the top cover off of my stock air box and tied the filter down with elastics........what can I say I'm cheap.........Sounds good, you can really hear the spool better. I'll be getting a K&N drop in and I'll tie that down too.

 

i sold my hks rs and am now currently using the dejontool hard pipe and stock airbox. i think this was a big mistake because my car chokes when i try and boost hard. as if its hitting fuel cut off or something. i think the reason for this is because my car was tuned on a safc for the setup with the hks intake. the stock airbox must be throwing the a/f off because its not tuned for it. on top of that i really really miss hearing the sound of my hks rs. im going to pick up a helix intake so if anyone is interested i will have a dejontool hard intake pipe for sale. $100 obo.

 

haha.. damn dude, I just saw you post up in the other thread about the RS for sale and started worrying something was wrong with the one you just sold me.

 

acutally i wish i never did sell it. but you paypaled me the money so i couldnt turn back. have you gotten it yet? if so how do you like it?

 

What about Apexi?

How important is a tune with a CAI?
