Am looking to fit a FMIC to my LC in the next week or two,am just wondering exactly what does this pancake pipe do? It looks like it restricts air flow to me,if so why ?

Basically it has been flattened "hence pancake pipe" so the wheel doesnt make contact with it when on a full lock. Its not actually restrictive, cause its a 60mm pipe, been flattened, plus us derv boys are using them. Jonjay is using one on his 257bhp TDI with no problems 
Ah right,cheers Brad,so there's no need to upgrade this pipe,all i'm needing is pipe, from the pankcake pipe to the IC, and the IC to the throttle body then,with a map sensor built into that top pipe.

No mate, not really tbh with you. What intercooler have you ordered mate, got a link or pic, if you have ordered the same intercooler as me, youve got all the routing for the bottom pipe sorted as our route for the bottom piping would be the same
Plus ive got a forge map sensor replacement pipe if you take a look at my thread

This is the FMIC

and this for the pipework

but has been pointed out that they are rubber couplers and they should be silicone ones,so will need to re-source the pipework

i love the theory that that its not restrictive as its a 60mm pipe flattened....
if you flatten a pipe of course its going to be restrictive, it will have less 'volume' capacity.
For a set amount of material, a tube shape is the least restrictive.
however i do agree that its this shape to provide clearance for the wheel when on full lock.

Well i look at it like this, get a piece of silicone, say 60mm for example, and stand on it slightly, but not squashing it, thats what i see the pancake pipe like
grab a garden hose when flowing steady water and watch the water change when you press it would be a better example
minimal alteration would in turn cause minimal effect but as the end of the the day something squeezed down to make it 'fit' is always going to be a compromise but then we are not exactly flying to the moon are we ?
ok, take a square pipe. Its 2x2 so has a volume or 4. (2x2).
Now squash it, or make a rectangular pipe using the same amount of material, lets say 1x3.
this uses the same material as has two sides of 3 and two of 1. (total 8)
But whats the volume? its only 3....

Neuspeed 481085
The stock pancake pipe flows 355cfm at 25 ft of water on a flow bench. In comparison, the round NEUSPEED pipe flows 426cfm at 25 of water.

I replaced my pancake pipe with a high flow one and I would say it did make a bit of difference
I've sold it now I'm sure the new owner will comment on its performance once fitted

Who sells these in the uk?
THS but they sell it together with the silicon pipe to the TB of the 1.8T petrol leon

other option is neuspeed

looks like SFS has made an ungrade, but gone along the lines of a larger pancake rather than a tube which might fowl on the wheel

The pancake pipe is designed so as not to restrict the flow, as far as possible. The narrow section has a greater circumference so as to keep the cross-sectional area similar to the circular section.
