Thanks for the suggestion. I will certainly pass that along as well. Anything we can do to make things better we want to do it!

Thanks again!

 

Some pics and a brief vid (I'll try for a better one tomorrow)

 

SEXY! Thanks for posting the vid! Worked very well to illustrate your point!

 

how long till the ECU adjusts to do new intake?

 

Nice sound clip, I am debating if I should get the turbo inlet hose you have, notice power gains and do you happen to hear turbo spooling more?

 

I couldn't tell you the difference between the CAI w/ inlet hose vs. w/o as the hose was on before the CAI. When my car was stock I noticed an improvement, and since the CAI it is very noticable. Definitely more turbo noise w/ the CAI (but again, I don't know if the inlet hose improves it or not.)

Its a great combo!

 

The inlet hose does produce more HP. Some dyno results here: CLICK ME!

Then click on charts!

Thanks again folks.

OH: ECU relearn. The ECU is adjusting all the time. But yes it will advance timing, etc. once the intake has been installed.

 

I have a quick question: I noticed the filter "jiggles" , for lack of a better word, when the car idles. Is this normal. Everything is tight... could I have overtightened the shroud? Or am I being neurotic?

 

Probably slightly neurotic! But seriously, as long as the shroud is snug, you should be a-ok. At idle the filter may jump around a bit. Normal!

Thank you!

 

Ah jeez. I knew I should have held out for red instead of black. That looks SO SICK!!! Especially with the Chili Red paint! Oh well.

 

That's what I thought...

And thanks for the compliment rattmobbins!

 

quick question, so i know the opening for the fresh air pipe is next to the left headlamp...but with the hoodclosed, how much air really gets in there? i know i must be missing something.

 

Tons actually. Like a surprising amount. We do all our dyno testing with hood shut and breeze over the front of the car. So those gains published are from that situation. We do NOt recommend leaving the hood scoop closed, but either remove the screen completely or open up the holes.

 

I got my Alta CAI installed and it is working fine. One step I skipped is unhooking the battery........Why do that???

Should I do it now??

 

The issue is that you risk causing a voltage issue with the MAF sensor. But if you have it back in and everything is a-ok, then you have nothing to worry about.

Enjoy!

 

I guess I got lucky but your post will help explain the potential problem for those future installers.
Thanks!!!

 

has anyone experience a noticeable loss of torque with the intake?

 

fedex showing a delivery date of dec 06 shipped ground to hawaii. LoL.. (perhaps it'll be here sooner as fedex does have to fly it in)

Most stuff I order online I have to ship 2nd day air at very expensive rates. Kudos to Alta for saving me lots of cash on shipping =)

(or.. I wonder if fedex has a sub that crawls along the ocean floor?)

 

no, have you?

 

get ready for good times!!!

 

I have experienced NO loss of torque what-so-ever. The point of performance parts is to INCREASE torque and HP, not decrease it.

 

I have noticed the opposite. Installed the CAI a couple of nights ago, and there's definitely an increase in torque. My foot seems to have become heavier too.

 

Got mine in and installed it in about 40 minutes. The hardest part for me was getting the reducer hose on both the air inlet hose and the pipe on the shroud.

The washer problem spoken of earlier has been fixed - there were two washers on the bolts with the nuts screwed on so they HAD to fit =)

I have a couple suggestions for the instructions though. Remove the single bolt holding the bottom of the old filter tray and twist the whole tray instead of the air inlet hose to remove the air inlet hose (steps 5 and 6 of the removal portion). I couldn't twist the hose itself enough to do the job. Twisting the whole tray was MUCH easier.

on step 1 and 2 of the install portion step 1 says to tighten the shroud yet step 2 says install the reducer coupling but don't tighten it until the shroud has been tightened. The coupler may have been easier to install had I not tightened the shroud in step 1.

I had 1 clamp left over - perhaps this one was supposed to replace the stock clamp on the turbo side of the MAF. I just used the stock one and it was fine.

I haven't had a chance to take it on the road yet, but just starting it up and goosing the gas to ~2500 rpm made the psshhh noise fairly loud (indoors). I have yet to apply the W.A.F. test. (wife acceptance factor)

 

ok, I just got to take it around the block and down the road a few times. I already know it is going to fail the WAF - which stinks because I did notice a difference in power. The guy riding with me described it as "SICK!" (which I think is a good thing because he was grinning so big).

If you like a fairly loud (not STI loud) pssht, you'll love this. from 2k-4k you can hear the air being sucked in (really!) and above 4k you can hear the turbo spinning screaming noise. All the r53 supercharger whine lovers can eat your heart out. We can whine too.
With windows up, radio off, and driving conservatively, I can still hear it a bit when I let off the gas. There isn't any hiding it completely.

conclusion - I love it but I am sure the conservative wife won't.

 

Sweeeeet ....just blast the radio so your wife won't notice....just say you wanna test out the speakers
