Williams Air Scoop

[king.stromba]

I was looking at my friends Pug 106 gti and he has a air scoop that sits ontop of the radiator and i guess it forces air into the air box. It must work pretty well because with just a chip, exhaust and this scoop his car is very rapid.

I tried a similar thing on my Williams. I took out the fog lamp and led a pipe from the original ait intake to a second pipe. This pipe led to the front of the car and to it i attached a 12 inch diameter funnel. The narrow neck of the funnel was cut to the size of the tube. Now ive tried taking out the fog lamp before and i didnt really notice a difference, but with this second tube leading to a funnel i was getting an induction roar and the car seemed much faster (at higher speeds). In fact it was one of the best things ive done so far. Now obviously i wont keep it like that, i dont want a funnel attached to the front of my car, so im going to design a more asthetic version. Also remember that the piping was pretty convoluted and bent. The next version will be straighter and a wider bore.

Has anyone else done this? If not, can someone do it to see if it makes as big a difference as i think. I can only guess that i wasnt getting the full benefit of the chip, decat and exhaust i have fitted because there is still a restriction on the inlet pipe to the inlet manifold.

yes, im planning on doing similar...iv got a bmc cda airbox, but no cold air feed going into it. just waiting to get a new bumper cos some w@nker crashed into mine and its cracked, then im gonna sort it out!

yeah i done it on my 16v, i took the fog out, made a simple fibreglass scoop sitting just behind the hole (sealed edges with silicone sealant) widned up the arch liner and the hole in the engine bay where the OE air feed pipe goes through to ~105mm bore, which feeds up to the induction kit (formerly BMC) I used B&Q 100m ducting, they do two types though, thin stuff which lasts about 10 mins and some semi-flexible stuff which is a lot tougher and only £4.50 per metre.

Breathing was much improved especially at speed and on cold mornings,definately a worthwhile mod.

Mr Coolspot has got it spot on. I was experimenting with these sort of things a year or two back. Basically you need to use the foglight hole so that you only have two bends - a scoop in the foglight with a bend behind it feeding into the factory hole that goes through the subframe into the engine bay, then another bend upwards from that to your airbox or whatever youre using.
