Cobb intake (SRI) installed....review

I installed this thing this afternoon. it took about an hour because i had a slight issue and that is why i'm writing this for those who will embark on this in the future.

the issue was getting the little 90* "elbow" out of the stock intake side. the Cobb instructions make this seem like it's a matter of simply wiggling it out once the clamp band is pinched. well, it wasn't. In order to NOT break it in any capacity as it's a pretty fraglie looking plastic elbow, i deviated from the instruction order and removed the stock intake tube first, detached the clip from the elbow and tried to remove the elbow from the tube with it out of the car. Solved that problem, just had to give it an 'unscrewing' motion while wiggling/pulling.

the stock rear band clamp that holds the stock intake tube on is different from the front clamp type, which means that its a typical worm clamp that needs to be loosened alot without fear of a nut dropping like the front black clamp.

be careful when undoing the 10mm nuts for the intake bracket. if you drop one of these and the fall to the undertray, good, because you can reach down without an intake in there. however, its very possible that they WON'T fall all the way down there and get caught up on something. so...be careful.

the bolt set they provide for the resin MAF housing thing connection to the bracket was missing two regular washers...or, their directions were wrong. either way, i added the washers as per the directions.

i'd like to comment on something that i didn't read when researching this thing. the intake sound on this thing is alot more pronounced that what i thought. i come from hondas, cars that don't come turbo, so...when someone adds a turbo...it sounds like this because usually they have a short intake tube with an open element filter on the end...like this. why i thought it would be different, i dunno, i guess because it's SO quiet stock, but it's very loud when the turbo spools. is it a good thing? absolutely, IF you like that aggressive sound. I have a TXS hybrid valve so that is also more pronounced than before in the orchestra going on under there.

as far as power, it's hard to say because it's raining out and when it's not raining, it's wet. i'll have reports tomorrow. i do notice that there there doesn't seem to be a quicker spool time, but when it does spool at about 3k the power increase is definitely more than stock. it's VERY noticeable.

more tomorrow, just gotta watch out for these (five-0)(five-0)(five-0)
 
I put mine on a few weeks ago also but mine had all the washers like in the instructions. I also had the same issue with the 90 degree elbow where I tried for a good 30 minutes to remove the hose by twisting until I realized I can just unsnap it right before the elbow.
 
Call to make sure they didn't sell out first, before you place an order there. Else they'll take your order and you won't get any other update until they get another shipment in (no call, no email, no update on their web system) or you call them...
 
********** FTW.....although I didn't get all the washers......and that elbow was a PAIN! Love the sound though and the butt dyno says a solid 10-15 whp. I am very pleased with my choice.
 
The elbow had me stuck for a good long while.

Do you have a boost gauge to tell whether or not you are spooling up faster? The difference won't be much since there is still a lot of restriction from stock IC and downpipe / exhaust / whatnot... but the difference will be there.
 
A tip to help with tight hoses: Use a little engine oil for lubrication. It helps a whole lot! And I don't mean pour it. Just a little drop on the tip of the finger.
 
ok, i've had the chance to enjoy this thing for a couple days with clear roads. my initial impression from the day i put it in is the same- full spool seems to be at or slightly before 3k. power increase is definately there and has been detected by not only me while driving alone but also my wife as a passenger.

coming from the honda world, seat of the pants can be deceiving- this is why: when you have a vtec engine with big cams, if the pre-vtec tuning is not done right but the big cams are, or if the engagement is incorrect, the seat of the pants feeling will be more intense because you will feel the car transition from a poor power tune in the rpm range to the optimized, so the tq gain is felt easier. the goal with vtec engines is to make the curve totally smooth with no dips at the crossover, and this type of tune yields less seat of the pants impression, but it's ideal and actually means you are making more power across the board.

needless to say, this is not the case here. the gains are from spool to redline, and that brings me to another point. it seems the car doesn't hit the 'wall' that it hits stock at the upper regions of the tach. i've noticed that it seems to pull past 6k rather easily at this point. this might be a combination of the well sprung and well sealed turboxs valve and the intake, but it's there.

i will have my dashhawk today so i am considering taking this thing out to log boost attitude and other behavior, and then reinstalling to counter log for comparison.
