hey a win is a win, whether by accident or design! lol
I presume you want to retain the headlight... rather than replace it with a duct to the airbox?

Whether you believe you can, or you cannot, you're probably right.

I'd forgotten that! The new c/f front clip.

The plan is to run sans lights to start with as this still allows the car to be run on the UK highway. On the original body panels there was an intake for the filter, which was going to be in its own sealed air box where the headlight would have been. The plan now is to locate the filter in the same area but without the box. Also the rad and IC won't be sealed to start with as this all adds weight and complication. When the car is working the air, water and engine temps will be monitored to determine if additional ducting/enclosing of filter and/or ICs is required. No point in fixing something that ain't broke :-) The round holes and the intake under the original one have been removed as they aren't required.

Nice low pressure area at Base of screen, you could run a reverse scoop?

Nice low pressure area at Base of screen, you could run a reverse scoop? Area at base of screen is high pressure but, yes, that would be an option. However, the lack of clearance between engine and bonnet (around 25mm) precludes this. I have thought about placing a filter under the steering rack in front of the crossmember but the filter surface area would be a tad small. The main constraint is keeping the cross sectional area of the ducting between the filter and the turbo equal to a 125mm dia pipe. It may have to be wide and flat, a bit like A/C ducting in car floors. Found this at Plumbing For Less :-) Could make an excellent puck for a mould :-)

What are you fitting for Debree protection from going up the tube into the Turbo?

have you got a link to that fitting, looks just like something I could use.

Look at Wavin sewer pipe attachments, or air con / heating ducting.
I think car builders solutions do stuff like that too.

It may be something inside that I've missed but what is it like routing pipework that is the same diameter as the compressor inlet instead of the reducer that is currently on there? Otherwise, I'd be inclined to redo the intake pipework in something a bit more solid and mount the air filter in the middle of the radiator Vee

Otherwise, I'd be inclined to redo the intake pipework in something a bit more solid and mount the air filter in the middle of the radiator Vee The pipe is this size so that it clears the trumpet :-) This allows the turbo to suck air from behind as well as from the front, increasing the volume of air sucked in. This is the ideal design but, however, I think that I am going to have to compromise on the design due to available space. Mounting in the V is the obvious solution, but this would disrupt the air flow to the coolers. As we are running marginal coolers due to space restrictions (could be larger now that I have a flip front but they are staying) this would be risky. Instead I am thinking of fitting a panel filter along the bottom of the rad with the intake pipe running under the rad and then up to the turbo.

What about casting the pipe onto the underside of the bonnet? (Does that make sense?)
You could cast effectively a half pipe - with an opening at one end for the airfilter and then a short piece of connecting pipe at the other end for the intake.

I was about to suggest a panel filter - then you’ve “only” got the 125mm tube to worry about..
Seeing the air inlets on 600bhp trucks, you can suck a lot of air up a long, thin duct which might be easier to route? Best start saving those Weetabix boxes..

Funny you should suggest that, I was discussing my options with my aero guru this afternoon and he suggested something similar, only mounting the filter on to the bonnet. I need to do some more thinking and measuring

Why, are they lighter than Weetabix boxes?
