BMC pipe reducer size help please!

[Pete 0]

Hi guts, I've bought a cda, the 85-150 model, which I read won't fit the car unless I use an adapter

 

Does anyone know the size and shape of what I need to get to fit my MAF so I can get it before the intake arrives and I can fit it straight away. A link would be perfect lol, as there are lots of bits like that on places like eBay, just need to know which to get...

 

Tha in advance,

Pete.

You need a straight-walled cylinder of silicone pipe, 100mm long and 83mm inner diameter. Pick whatever colour matches the rest of your hoses ;) Less than a fiver posted. (link)

 

I had much the same confusion - the engine end of the CDA is supposed to be 85mm (and the MAF 80mm!) but the 83mm hose will fit over both. Go gently as it'll need a little coaxing onto the CDA, but it will make a nice snug fit. Note that if you use the top bolt of your aux belt tensioner to mount the CDA, you'll need to file the end hole a little larger in the perforated metal strip to get it over the bolt - also do the bolt up extremely tight, otherwise the belt will slip under load and make an annoying noise - and you'll have to take it all apart again to tighten it! You can also use a longer metal strip and mount it to a preexisting bolt hole in the suspension turret - bit less tidy-looking but easier to maintain.

 

You're welcome! :)

Nice one, I've ordered one :-)

You'll need a jubilee clip on the MAF end, by the way. The CDA end is so tight you can do without :) I've got one sat about in the bits box if you want it?
