Injen 17hp/16tq???
Check out their website. I THINK they posted dyno sheets... http://www.rebelautoworxs.ca/index/
Your going to see pretty much the same gains with any good name brand intake, As stated get the raw or what for OTTP's new intake because they are Stainless steel, Not aluminum, Problem with the aluminum ones are they get holes rubbed in them, I have an injen and its nice and all but its almost rubbed through in a few spots so il probably upgrade to a stainless one
Like i said the most you will see is like 1whp difference at most between intakes. The only stainless intakes are RD fabs, Raw, And OTTP (soon).
Now if you plan to go to a smaller pulley you may see gains with a 3'' over a 2.75'', All the stainless ones are 3'', Im not sure if there are any aluminum 3'' intakes or not but im pretty sure the injen is 2.75''
Well when I had my injen intake on and at 15 psi and with copper core plugs and a cherry bomb for a exhaust I made 220 to the front wheels I hope that kinda answers you. this was on stock computer with the boost mod. So just do the math lol
Lets just say this, I have dynoed my car with the stock intake, Removed the lower housing (aka air box mod) and finally with the injen, without touching the tune there is minimal difference in the air box mod from stock (keep in mind I just removed the lower section and didnt cut the **** out of it as I want to keep it pristine.) The injen showed power throughout the entire rpm range. After retuning the MAF for the Injen, power went up a little more. I dont post dyno numbers on this as its all bs to the AB mod guys because they feel the difference and Im lying. All dyno runs were performed on the same day. As for total gains, as said above the gains were more impressive throughout the rpm range and not at peak power.
On installation problems with the injen, I took a length of windshield washer hose, split it lengthwise and used weather strip adhesive on it, then take the split end and push it over the sharp edges around the hole that the intake will go through, position intake correctly and tighten, after two years the intake looks brand new and there are no wear marks on the tube at all. If you are fussy like myself the hole will look like it is surrounded by a factory gasket.
