We haven't be able to do any tests yet as we've only just started doing them but Carbon Speed claim up to 50% increase in airflow.

Hey Guest one of our sponsors Progressive Parts is running Black Friday and Cyber Monday offers - more details here
Thx for quick response.
Would u by ay chance have some of that proof?
I have been struggling with this issue myself.. I have the Forge CAI... noticed 20g/s decrease on my std cupra. Car sounds awesome tho...turbo seems to spool faster.
Now wat I need to know is whether the file needs to be adapted for this to be increased?
the ultimate question- how does a regular bloke with VAG.com n all these various CAI's at his disposal decide which is better?

Where is the cone located? If it is in the wheel arch behind the bumper, the chances are there is no outside air being driven on to it therefore its making do with limited hot engine bay air.
it unfortunately only goes in that space... there is a small duct for airflow to brakes- this I've drilled full of holes to allow some direct air onto the filter but minimal improvement. Its just so hard to decide which is best.
Also tried building my own stuff and all flow less than original.. I have yet to test EVOMS/BSH/Dbilas. Way too costly to import into South Africa.
Maybe my testing process is flawed???

I struggle to see how you can improve on anything that is getting a clean cold air feed straight in via a direct bonnet or grille scoop.
Also the more pipework / turns in the pipework that exist between the intake point and the throttle bodies can surely only create more disruption to the flow throughput. You'd think that the air literally needs to be forced in rather than just absorbed in free air that may exist around the unit.

I was going to say this yesterday but bit my tongue before I did. I had a Carbonio and noticed no gain over the OEM intake with the Pipercross filter than with the Carbonio and Pipercross filter. There was no change in noise either.
The dbilas on the other hand uses the OEM intake like the Carbonio (ultiles 100% of the air feed in) and feeds it directly to the turbo without having the engine cover to contend with. There is also a nice noise with the dbilas to boot - its there but not in your face like an open cone.
Without having measured the gain in bhp, I saw a significant increase in airflow after the dbilas.

Good to know DJ.
Think id just go straight to the dbilas for the extra ££.
People say the OE one dumps half of the airflow straight into the engine bay
and this CS doesn't, how is this? The CS is a copy of the OEM intake only made from a different material correct?

This is the intake from a Cupra;
This is where the intake meets the slam panel
This is the rear of that same unit. The top half feeds in to the flexi pipe that connects to the engine cover, and the bottom half puts air in to the engine bay.
What the Carbonio and the unit above does is close the bottom hole and feed the air that would have gone through it in to the top hole.
or you could modify this and move the flap so more air goes into top one
Yep. To be fair there would be a bit of work involved, but thats all this kit does to be honest.

Possibly a silly idea, but can you not block the section that dumps the air into the engine bay?
You should probably cut the pipe work back so that the cone sits closer to the OEM air intake and fit some kind of shielding like the EVOMS kit has to stop hot engine air getting to the cone.
Yep. There is about an inch of recess between the end of the engine bay opening and the point where it splits though.
I would like to see the official g/s and bhp difference the aftermarket intake scoop gives over the OEM unit when both have the benefit of the Pipercross (or similar) panel filter in the OEM engine cover.
If you do manage to block the bottom section of the intake pipe I think that you'll be causing such disruption to the airflow that it may be counter-productive. The smooth edges of the bespoke carbon intakes are testiment to the efforts of flow testing the air.
I know air and water are 2 very different materials, but if you drop a large pebble in a fast flowing pond the get quite a void of disruption in the wake side of the pebble (I'm sad enough to have been stood in a cold Yorkshire river on an A level Geography field trip). The thalweg (point of fasted flow in the channel) could be disrupted by around 30%. Now although I have no logic to suggest air does the same, if you watch aerodynamic exercises with plane wing turbulence the smallest difference makes a significant change when you increased the rate of airflow to very high speeds. Apologies for a very dull science lesson, but I'd rather save you time and effort which could be spent on properly tested kit like this product advertised by Damian.

Yep, and thats why it would be useful to see the gains from this kit as the square edges and basic design of the OEM intake would make remodelling it a real pain.
Looking at my OEM intake, I wouldnt bother trying to modify it but its design is interesting. VAG engineers are not that daft - the opening is probably there for other reasons like making sure driving rain does not go straight through to the turbo. This is the only thing I can think that may be a problem to any kit which has this type of design and it would affect the likes of my dbilas also.

Caaaaant wait to fit my dbilas
If you have VAGCOM, it would be useful if you could do a before and after measurement of g/s air movement. On your car it will probably be at around 240g/s.
Nail head hit !
I took the top off mine as it was vibrating (between 1200-1700revs ) to see how I could stop it, the amount of water marks inside was quite shocking, now this may have been only a little amount of water being pushed through with the force of my motion, but even still, hyperlock on the engine is not something I'd like to have happen.
I'm sure if you did low milage & only in the wet, no worries (I do 4-500+ weekly)
2p
(I'd still like some fancy carbonfibre in ther bay though

I only do 10k a year, and whilst I agree the water could be an issue, there is a deep section on the underside which can manage a significant amount of water build up before it would head up the neck and into the pipe. You'd expect under heavy braking this should come out, but impossible to tell really and a very interesting point to watch out for.
