What vents do you use n wheel arch???

you can use the ones off a tt, or make your own.

wazzer, when i look the funnel was blocking a fair bit of the ic, did nick test to see the benefits of keeping it? either way i suppose its too late as mines in a tip somewhere now

The vent in the wheel arch, i got from b&q £4.99 . ill cut a square hole and black silcon it with 4 pop rivets holding it on. I got the idea from looking at a newer car when i was painting car park markings at work.

lol, its a cheap alloy one the vents face down 9x4 i think but im chopping it down and spray it black.

It's to do with channelling the air to the cooler and then allowing it to escape. There is a bit of theory behind it ie low and high pressure points creating voids bit it's a lot to try and explain.

The main reason for it is the air hitting the front of the cooler is not very efficient without the means to escape. Also with the funnel you are forcing the air to hit the IC and not just glance off

any1 have any pics of the arch venting on there golf

I found 1 by searching it on here.It was a tt one he bought and put it in his arch.Have a search on here took me a bit to find.

I remember autospeed adding a vent to the wheel arch, it did F all. Reason being was the vent design was not efficient enough in improving air flow and it had no effect on the pressure under the arch which is what they where testing and measuring in the experiment, instead they decided to use a FMIC do to a bigger access of inlet air flow on a pd engine which are far more on boost than our engines, have a read:
