Seeking advise on airfilter feed pipe location
I've got an enclosed airfilter but it needs a cold air feed obviously.
I'm really struggling to find a suitable location and where to get cold air from!
I can't get the filter at the front of the car because there's too many pipes in front of the engine, the intercooler and radiator pretty
much fill the nosecone up too
The only way I can see to get air in is via the bonnet scoop but that would involve running a flexy pipe over the cam cover and making some sort of
scoop to seal behind the bonnet scoop,
Or
Having a NACA vent in the side of the bonnet, but I'm not convinced that it'll pull enough air in or look very nice. Also there's
the complication of connecting and disconnecting the fleed pipe when I want to take the bonnet off.
Anyone else got a solution? Bloody turbo engines!
Thanks

How about going through the bulkhead into the scuttle area, above the passenger's legs?

I could do, but I was looking for air that's cold on the move. The air above the passengers feet it's relatively warm as all the heat from
the engine

It's what I've ended up doing.

Don't know, I haven't done any serious driving with it yet. It's a compromise, but I was really limited as to what i could do with
it. I couldn't duct to in front of the rad as suspension/bonnet/engine get in the way. If it faced forward it would be sucking up everything
thrown up by the front wheel. Now it pulls air from behind the dash. It may be warmer than ambient, but in gulping 4.3l per rev then it's
going to pull some fresh air in, and it will be cooler than air from the engine bay.

When my car was SC it just had a feed from a hole in the side panel. Its been well proven that ram air does not work at our speeds an either way cold
air is more benificial. Direct the tube towards the side of the engine bay and put a hole in the side.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

I'd be putting a fillter out of that bonnet
I'm lucky I got mine over the boost hoses into the top of the nose cone, don't forget though that I presume your intercooled so it
won't make much difference, I'd run it where ever you can then measure the inlet temps before your make a radical change

The fact is that nowhere in the car will be anywhere near as hot as the under bonnet temps. If at all concerned, make an open plenum inside the
scuttle and line it with heat mat.
The under bonnet temps on mine rose to around 90 degrees in traffic last summer, god knows what a turbo would do to it

Thanks for the ideas guys. I'm waiting on a flexy pipe to come so I can see what will be possible. Just don't want miles of flexy pipe
messing up the engine bay
