Review UAS CAI

[Jono]

hi guys,

Just got my CAI,
ive only installed the intake pipe and i must say i am a bit suprised at the quality of the pipe.

Negatives
1. intake pipe does not fit "Snug" around the throttle body, it seems too big for the throttle body, but it does fit once the clamps are on.
2. clamps for throttle body side of intake is verrrry tight fit. it took a while to push it onto the end of the pipe.
3. It seems home made as the rubber looks cut with a stanley knife
4.Engine seems to be making a knocking noise after installing the intake but not before it. I have had a blitz exhaust installed last weekend plus this mod, i think i might have to reset the ECU, it could be the air fuel settings. hopefully it is.
5. Breather pipe doesnt reach that crank case outlet thing' when the pipe is totally pushed in. i think thats what it is called.

Positives
1. There quite a nice tone to it reving it to 4k 5k
2. rev's feel smoother
3. intake looks huge and verry smooth inside it.


im going to be installing the rest of the kit this week, hopefully with the reset and installation of air box and piping, it should go well.

im pretty confident it will

1.There is a little bit of extra room but that's why you have a clamp to tighten it.
2. ummm did you loosen it??? haven't had any problems fitting them.
3. when they come out of the mould they are quite rough and have to be shortened to length. they are rounded on a belt sander.
4.dunno what that is but its unrelated to the intake pipe
5. really??? i measured it off mine when i cut it... if that's the case i can get you a longer length and send it to you. All the others fit fine

[Jono]

to steve's reply,

1. yeah, it was more than i would expect. but i guess thats my opinion
2. It was maxed, and was still tight, i think i might try sand some rubber off so it fits better
3. prolly the only real downside is the Aesthetics of the Intake.
4.i think it is related to the pipe but also the ECU, cos it wasnt making as much noises with the standard intake pipe. and as soon as i took it to 4 5k a couple times, it started making more knocking' noises.

is this a possible reason for that problem? im hoping it is, or else i have a real problem.

5.yeah just pm me, and ill get u my address.

Hmm...
To me it looked like after the 90 deg corner coming into the throtle body your intake piping was much longer than my blue one...

So it may be a possibility that i mentioned to you that it's a bit longer and you just might have to cut it a bit shorter.

That way, it will bring your breather thingo closer, and i think will make your clamp feel looser.

BUT, I actually like how your intake pipe is longer and sits closer to the snorkel hole, that's why I like yours better cos it might fix the below problem...

My Review: I got mine today too with Jono's and, I must say you can feel the difference, even if you have a huge airfilter allready and the stock intake piping. BUT The problem with mine is that the heat shield doesn't sit right, due to my huge 6" SUS Blitz Air Filter.... the top cover is bent higher than normal... and the whole thing is slightly funny. Maybe I should take some pictures... to show you...

I also noticed that the intake piping is quite soft, and rubbery... and transfers heat quite easily due to that fact, would wrapping the intake pipe with heat sheilding stuff help?

Yeh, thats a possible solution, but the UAS intake should be "bolt on", i shouldnt really have to be cutting anything.

I agree...

[Jono]

Just did a ECU reset, and it sounds ten times better, no knocking noises as such. so hopefully after a "spirited run' it should still be fine after that.

Jono

[Jono]

After the 'spirited run, its running really well, with only the Intake, i can feel some gains already.

so i guess ECU resets are a must for CAI?

Jono

[TheSentry]

Yes it is. An ECU reset allows the airflow to be adjusted to allow for the extra intake a pod allows.

I dont mean to sound like a dumbass, but how would i reset my ecu
I know how to do it in a silvia...but my fto..havent even looked!!

[Boris]

It's ok, we still love you

You just disconnect the battery for like 30mins.
If you are keeping a tally of your km's on the odometer counter, then it will wipe it... and you might need a security number for your stereo.

[ruchi]

just to clarify, it will clear your trip meter not your odometer

Aside from the radio code, some alarms also have codes, so it pays to make sure you know ALL of your codes for ALL of the various devices before you disconnect your battery.

In resetting the ECU the car may drive a bit strangely for a little while as it relearns your driving style and adjusts to the air / fuel mix.

Resetting your ECU is also a good idea if you change any main "breathing" component on your car, or if you switch to a different octane fuel.

[21mrk]

hehe thanks, didnt know it was that easy

[smorison]

the piping is thicker than the OEM piping...

plastics don't transfer heat as quickly as metal.

The intake and airbox were designed to use Unifilters NOT huge pods from other companies.

if your engine is running rough it may be leaning out a bit or something like that as suggest do a ECU reset as this piping allows a LOT more air into your engine than the stock piping.

The kit as a whole is designed as a bolt on kit, if you purchase only parts of it, it's hard to guarantee that it will be bolt of for every possibility out there.

The crank case breather is my screwup not UAS as they were flat out and i cut the piping - at the same time it's exactly the same length as the one i re-fitted to my car and the one attached to SilentBob's car which fit fine... so i'm a little confused as to why yours won't fit.

I know, i wasn't complaining

Me and Jono have already done this It's much better.

Steve... read the above carefully... We are saying that Jono's piping, is longer in the bit that attaches to the Throtle Body, not the pod. And, that makes the diameter bigger, when we put his pipe on to the throtle body, i can leteraly stick a finger imbetween the pipe and the metal.

So, that end of the intake pipe, should be the bolt on bit...

Steve... The lenght of the breather is the same, like you said. BUT due to the above problem of the actual intake pipe being diffrent makes the crank case breather too short to reach the crank case.

hmm... that's strange the longer it is the narrower it should be as it continues to taper off in the mould... that's really wierd... and yeah sorry trying to answer questions and work sometimes leads to incorrect understandings of what was said.

you can shorten the actual pipe if you like it's pretty easy to do (use a hacksaw and a belt sander if you have one to make it smooth).

[G_A_V]

is the crank breather supposed to attach to the intake pipe ? when uas did my intake pipe they didnt attach the crank breather, and i didnt think it was important cause its soo small and tucked away, it wouldnt get much crap.
they used 3inch cai piping for my pipe, and i dont think it would be possible to attach the crank breather to it and seal it at the same time

[Jono]

yeah, i dunno whether i wanna start cutting into it.. normally when i do, i do too much and wreck something...

plus i dont have a belt sander or a hacksaw..

Maybe i should get a replacement?

i'll send you a longer length of breather pipe that'll suffice... no need to change it or start shortening it if your worried about wrecking it

Finally got mine installed and have noticed a couple of things:
1) noticeably louder from about 4k rpm and above.
2) slightly better response low-mid rev range.

The increase in power may be just my imagination cos I had to drive an old Toyota Corona hire car while the kit was getting fitted . I'll have to do more everyday driving to make a conclusion.

I didn't get my ecu reset as I was told that this is not necessary . Will it adapt to the greater air intake after 100km or so anyway?
