If they are looking good I'll just keep the intake on, but if my AFR's are messed up or something I'll just swap my Injen back on and go back to the drawing board.

Hopefully it will be a good way to get pretty direct comparisons between a DIY'ed X and the Injen while using the same filter to see the difference.

With your Injen intake, how's your idle? Throttle response? Granted mine was a cheapo Weapon R, but I had major idle problems and reduced throttle response compared to stock. It felt like it made power, but my car felt like it was 10 years older, one of the main reasons it got ebayed and I'm working on diy'ing X's intake.

I have run every mod on my car with the same dyno. My first dyno run was 181.. So I would say its not high. I have seen higher runs stock than my 181.

This dyno I use is a VERY reputable dyno in Atlanta. Temple Of VTEC uses this very one when the dyno there cars. I think if it wasnt legit, they wouldnt use it.

i see. well your car loves the set up you have then, 204 is great with those mods.

maybe better with the xintake! time will tell!

i sure f'ing don't. they couldn't do it. said they were only set up to go through an exhaust bung that i didn't have. i gave them a pretty hard time, told them i'd pay and this is what they told me. sorry man. i was pretty pissed cuz it's the main reason i went to the dyno.

***MrKaz*** · 01-21-2008, 12:06 PM

that is no problem... that sucks that you couldn't get it done!

Red Dyno was Injen SR, Hondata IMG, DCRH, Stock Exhaust
Blue was with Injen SR--DCRH--Hondata IMG--PR2 TBG--Greddy Evo2

The Dyno was a Dynojet with SAE CORRECTED with Smoothing of 3.

after seeing many stock SI's dyno, all with the reported average numbers that a stock SI should have, and seeing cars with the same mods as your car, i would have to say the dyno you did your testing on reads high.

I haven't seen anyone sanding down the vanes on a stock air box so I thought I would give it a try. I had previously put in a K&N panel filter and removed the resonator and didn't notice much of an increase, but once I sanded the vanes it was a totally a different story. The car pulls much harder now. I'm sure I could squeeze more power if I went with the complete X Intake, but I wanted to keep the stock look.

hmm... Hawk and I did this as well- but I emptied my airbox of its innards as well.

**ErichPryde** · 01-21-2008, 02:41 PM

I don't have any current pictures, but this was halfway through the process...

I thought that the "innards" were there to help direct the flow evenly over the filter area, or are they for intake noise suppression?

NIGHTHAWKSI · 01-21-2008, 02:48 PM

^that may be, but ther eis soo much turbulence in the airbox that the "flow direction vanes" are nearly usless.

**ErichPryde** · 01-21-2008, 02:48 PM

hmm... I'm not very sure. however, here's a read you'll find interesting.

Tech - K20A2 RSX airbox mod
although this is for a RSX, the general idea should be somewhat the same.... someone on another website (I really wish I remember where it was) cleaned out their box and got a small amount of horsepower out of it.

shnichol · 01-21-2008, 03:04 PM

Thanks, I saw that article before, but it seems to address the intake limitations specific to the RSX. Other than freeing up some power, does removing the vanes on the Si airbox make the intake noise any louder?

**ErichPryde** · 01-21-2008, 03:29 PM

if it does, it's such an insignificant increase that you can't hear it.

**Qshooter151** · 01-21-2008, 06:41 PM

hey Emmanuel i have a question. my car was idling for a lil over an hr today then all of the sudden it starting idling up and down. i revved it up once to see if it would stop but it didn't. it wouldn't stop till i turned it off. i also have a CEL. i restarted the car immediatly and it idled fine. no loose hoses or anything. i'm going to get the code read now. be back in a bit. any idea what the hell happened?
