Be careful to take account of any extra air at the top end.. I know the guys who used to run my Tuscan Challenge car in Sweden experimented with a ram-air intake through a hood scoop in the bonnet. It apparently had some great effects on the main straights, but they ran into some problems with detonation due to the extra forced in at high speed not being accounted for in the fuel map. As you say, this is hard to account for as you cannot reproduce the effect on a dyno without use of a wind tunnel so a smart ECU or best-guess work is needed.
No problem, good luck with it! I'm looking to do the same with my Tuscan with dual ram air inlets and have a Syvecs s6 Ecu to control it which i can definitely recommend.. If my engine ever gets built then I'll get to see if it works; I've got a race datalogger which can read real time horsepower, so hopefully I'll be able to quantify any bhp benefit.

This does seem much more normal,forced air rather than having to pull air up.
Now here's an interesting point...well, depends on your definition of interesting I suppose, but anyway....the air under the front of the car will be at high pressure when the car is moving (assuming the air intake is located far enough forward to be in the high pressure area before the rake of the underside has its effect of causing low pressure), so it will be forced up the normal intake. Question is whether this effect is greater than the forcing of air due to "running headlong into it" - probably not as I guess otherwise air would actaually go the wrong way ut of the forward facing intake.My brain hurts now...

Well, now you put it that way.... just got to thinking though whether having two different types of inlet into an airbox always equals higher pressure air on the inlet side of the filter, or whether the lower pressure one could bleed some pressure off the system, particularly if it provides a lower resistance route for the air than passing through the filter.
I'm sure I'm ignoring a fundamental law of physics there somewhere.... the mod looks great anyway!

I can see what you're saying. It'll only be an issue if the current standard inlet has any ram air effect at the moment. If so, and the new pipe has no ram effect, then you're effectively providing an escape route for the airbox pressure. I'm sure I'm ignoring a fundamental law of physics there somewhere.... the mod looks great anyway!
To be honest, it's either rig up loads of air pressure gauges etc, or just fit it and test it.
The bigger issue is the one already raised that once you're going at high speed, the ram air effect from the new pipe will (in theory) increase. This means you do need some kind of knock control on the ECU to make sure you don't run lean at higher speeds.
Get the ECU sorted, and I can't see any major downside to the mod if the pipe's insulated well. Always good to see people trying new stuff!
Oh, and a pic for Clive (i've been stalking your car btw):
very interesting comments guys, I`ve often wondered if 2 entry points will provide an exit for another at the same time, I also have this little mod done to the undertray,(did this last year) a sort of naca duct effect, with a small ledge at the back to help cause a deflection to force the air up into the pipe at the same time.
I`ll have a chat with dnb and see if he can rig up a pressure sensor in the pipes to see whats going on when on the move.

Thanks Clive,
I was considering selling my sag but a combination of seeing some really pristine examples and the price increase has prompted me to look at area's where I can improve the car.
Not that mine hasn't been cared for, I have spent lots of cash on services/repairs but I would say it was an 'honest' example. I'm just not sure where to start with the upgrades. looking to spend about 10k ish. Interior is in good condition but could do with an upgrade in the next year or three. Do I respray or just blow the 10k on a new engine? Any guidance or thoughts appreciated.

Only you can answer that. What don't you like about the car that can be changed? 10k will give you a lot - but not everything.
There is a (normal) school of thought that says an unmolested car will attract a higher premium when selling, and modding a car you will never see a return. But then again a lot of the modifications we are seeing here I think will buck that trend...

10k is a lot, engine wise, if you have regular servicing, tappets done ect and its in fine fettle why worry?
I don`t know how you look after your car, but a full geo set up every year is a must, then perhaps a set of nitrons?
when is the last timeit had a full 12k service and did you get a list of jobs that may need looking at in the future? If so I`d address that first.

Thanks for the replies. That has provoked some thought. I have never tracked it but must admit would like to! I'm not to bothered about much more performance. Richard at Track v Road did quote for a new fly wheel and doing the clutch at the same time and i did think at the time does it really need it! I've had the car for 4 years now, it's the Silver sag EU05 FDK which made a couple of brief appearances on the classifieds pages about six months ago. I was going to sell it and get a Gallardo but when it came to the crunch i just couldn't let it go.
It has had quite alot spent on it over my tenure, probably about 6 or 7k. Last year it had a full set of Bilstein shocks, new discs and pads, new radiator and a quite a few other bits with the 12k service. Just had one advisory on this last 6k service and did some nice to do things like had the wheels done in anthracite as well.
Couple of little issues like back lights need re-sealing but nothing else body work wise and it spends most of it life in the garage. One of the main reasons i was looking at a Gallardo was because i fancied a different colour of car. That sound like something the Mrs would come out with. I really really liked the really deep grey Track v Road had for sale recently and i thought about a respray, am i allowed to do that?
I look at some of the pictures of how clean the engine bays you guys have the cars and i find it amazing. I have spent the winter months in there with countless tubes of autosol metal polish but am now at the point where i think the engine needs to come out for me to progress. That is where i fall down, it took me almost 2 full days to pluck up the courage to release the water bottle from its holder so i could send it to be powder coated black. When i'd done it i realised it wasn't such a big deal but lack the confidence really.
So i think in summary i'm looking at possibly a respray if i am allowed to change the colour, and a new interior. Any tips on who, where and how much?
Thank
