Home made - CAI

[jcscoob]

To nite i finished the cold air intake, its took a wee wile coz i had to strip the old coragated flex piece of craap out, work out wot pipe/bends/fillter i would need, order them then spend a bit of time getting it right, so the car has been off the road for a few weeks.

The stuff i needed was, all 80mm ...... 2 - 45degre bends, 1 - 90degre bend, 1 - alloy tube and a green cotton fillter the size and flow that i am needing.

Took the car out for a wee run just to see what like, and was more than happy with the way it was pulling/running, better than ever. There are a whole load off other bits to be fitted before remap date on the 25th, so now i canny wait []

Here are some piks of the home made high flow CAI [].....

From above and through the inner wing

Then inside the wing

and down to filter

All together

Good work!

Does the job and probably £200 cheaper than an APS one or whatever!  Andy F doing the map I assume?

Brian []

[jcscoob]

Yeah Brian down to Andys ! []

jc ... i thought we were not allowed to do induction kits on our my 99 cars ??!!

i would love a nice wee induction kit so i would !

but i thought it would just kill the maf ??

You are a clever caant JC.........is the green filter a dry one?

[jcscoob]

Davie, thats wot they say, but i have a frontmount and the hard pipe needs to go trough where the air box was, so its a must for me now[]

but unless you are going for big power then the std air box and a good panel filter will be fine.

As dry as a witch's t!t  !! []

Davie ,

You are one of the privilaged few to have seen under my jalopys bunnet []

99 and 00 do have fragile MAF , but vibration and oil contamination are the killers - make sure filter is not over-oiled and is well supported and it should be OK ( I do keep a spare MAF though ... just in case [:$])

Mine has APS CAK C/W K&N , MY'00 BTW - no MAF probs (phew thats enough abbreviations for one night [] )

BUT , Andy-F could not stress enough that adjustment to map was required if running the intake I have , due to the swirl effect of the pipe bends before the MAF . Without re-map , this causes the sensor to seriously under-read the airflow , which in turn will cause very lean mixture . . . .

cheers lads  !! will keep that in mind ally cheers mate !

Very nice work Jon, and I see the colour even matches your car.

Looks like it should be very effective and is that a cut out and meshed wedge I see in the background? Nice.

[dave_morgan]

Very tidy - good job!

 

[st3ph3n]

JC, that's some nice work mate.

Build some more and start selling them. Keep you in optimax []

[harvey_smith]

JC. : A really neat job. Tidy and impressive.

As Al has outlined above, it is imperative that you have the MAF Sensor rescaled by Andy F or whoever and this should be done sooner rather than later. CERTAINLY before you rag it.

About five years ago I fitted an APS CAK. 11mls later I had picked up #2 piston in the bore. This was the beginning of my excursion into Scooby tuning. APS at both M.D. and Technical Director level denied it could be anything to do with the CAK. However, some short time later after work with Bob Rawle we realised that when the inlet tract was altered the air flowpast the MAF Sensor also altered, hence the problem.

Take care until you remap.

Cheers guys[y] Its all ready mapped for a CAI (crap air intake), all i have done is change it for the better, its due in for a new map on the 25th and will be hardly driven till then. But when i was out last night it was showing 8 knock on the apexi hand set, witch is pritty good considering ! []

[frank c]

Good work Jon...very neat and tidy..

[dipsy]

Very neat and tidy there Jon

[the squiggle]

Good words of wisdom from Harvey

Very tidy indeed, wanna do mine next cause that is pretty awesome?

[harvey_smith]

Any alteration to the inlet tract is likely to alter the air flow presented to the MAF Sensor. It could cause rich running which relatively speaking is not a problem and you see the black smoke anyway. However you could get weak running and this will lead the VERY high combustion temperatures. In that condition you will not necessarily see any KNOCK or DET before serious damage is done.

[jcscoob]

Harvey thank you for the advice/concern[y][H] I will only be gingerly driving it to get some more work done on it then driving it again to get it mapped, all of boost [] .

Nice work Jon!

Is it completely safe having your filter down there? Will it not sook up all sorts of crap down there what with the lovely scottish weather filling your arches with crud?
