You haven't said (that I've read anyway) what engine you have.
With his 450bhp 2.0 Cossie powered 7 I'm not sure Hicost even bothers with water injection any more.
You sure you need it?
Cheers,
James

blackbird, it was only an idea, but after having a look at a water spray idea I think I may go for that, I still need to find an inlet temp gauge and
seder which im struggling with.

I haven't looked myself Dilley, but I imagine this shop might have what you are looking for
http://www.turbobits.co.uk
it was part of the link I put up earlier with an example of the water injection itself.
cheers,
Steve.
edited to add, the shop is nothing to do with me - it's the first one I found in google...

Have you considered moving the intercooler in front of the radiator? I am sure that will have a dramatic effect on charge temps.

It does look like you may have room to put the fan behind your radiator (if you have one of the reversible ones?) and therefore able to fit the
intercooler in the front as per Razman's suggestion...

yes I have looked at the turbobits website and it offers a lot of info, I have emailed them with some queries,
I tried fitting the intercooler in front of the rad but it gave me some overheating issues on the water side of things, I have had a look and think I
can encase the intercooler and duct it down the transmission tunnel and then fit water spray.
I still need to find a damn gauge and sender

also changed to a bigger rad now and fitted the fan on the back, but I hve no room to try the intercooler in front of the rad again, I think alot of
people who are building turbo conversions on bike engines are going to have some of the problems I have, Its not a case of bolt on a turbo and
drive!!!

If you are forced to have the intercooler above the enging then maybe some sealed ducting would improve things. As far as I can see you are directing
air towards the intercooler but you really need to seal the sides to force the air through it.

dpo you mean seal the sides up to the bonnet to force the air through, or seal around underneath to duct the air away????

The critical side is on the intake - it doesn't matter too much where the air exits as long as it can.

I suspect the net airflow through the intercooler as it is now mounted will be very small, you might even be getting hot air comming out  The
engine compartment in a Locost is a high pressure area, getting air out is just as important as getting it in.
Might be a good idea to stick the intercooler back in front of the radiator and then make sure you are getting adequate airflow out of the engine bay
(could use intercooler scoop mounted backwards maybe?).

The intercooler should be in front of the radiator as it will not actually be heating up the air (that is assuming there is no turbo fitted...) when
water is sprayed on it, the water evaporates quickly in the high airflow and the fins get chilled. No heating of the air occurs, rather the opposite
and the air gets a lot damper too, so the radiator behind benefits as well, since the process repeats on it.

Although a cheaper option I wouldn’t for the wet spray intercooler idea with the intercooler mounted where yours is, this method is usually used for
front mounted intercoolers.
Back in my GT Turbo days the most effective method was to use a charge cooler mounted on the bulkhead just above the turbo, in fact the one pace made
for the job would probably fit perfectly. Will dig out some photos later,
GT turbo’s those were the good old dayz!!!

you say that you now have a bigger radiator?
Is there any chance that you could move it over somewhat so the the intercooler could sit in the nosecone aswell - I know they're never going to
fit alongside each other, but at least then they would both benefit from the coolest air possible - I had a Lancia Delta Turbo and it had the
intercooler mounted off to the side, and only benefited from the frontal air a little, but I suspect that it was better than mounting elsewhere due to
engine bay heat?
All above only speculation, but thought I would throw it out there!!!

Dilley, how much space/clearance do you have underneath the bonnet? One random idea I've just had is this, and it may take a bit of explaining.
The under bonnet is a high pressure area on a 7, so air is trying to get out, rather than in. So, if you can duct cold(ish/er) from the front
somewhere, through a tube or possibly a tube formed as part of the bonnet (may have sealing issues?) and then have the intercooler lying near
horizontal under the bonnet and duct the air stright up and out through a naca duct to gain the best of the push from the high pressure and the suck
from the low pressure above the bonnet. This may allow you to use funny shaped tubes, ie wide but flat, to make best use of the available space, and
maximise airflow.
Or rather than out of the bonnet, you could use any spare space along side the engine for the pipe work. Shouldn't matter where it is, as long
as it gets a cold air feed and is sealed.

getting the air in shouldn't be a problem with a bonnet scoop, Its directing the air out of the engine bay thats the problem, I also have dax
side panels fitted to the car with the origional side panel cut away, this should pull the air out of the engine bay???

They the panels with the big gap at the back end? If so, why not just get an intercooler the same size as the gap and fit it in there? Just need to
make a duct for the front in a 4 sided pyramid kind of way and add some large pipe to the front. You could even turn the cooler slightly in the hole
to allow a bigger one if needed, thus increasing its efficiency a bit at the same time.

That is the source of your problem. As others have said there is high pressure inside the bonnet and you are trying to force more air into that high
pressure area - certainly not good for cooling either rad or i/c
As DIY Si suggests, maybe some kind of internal ducting might improve things but I think the only answer is to relocate the intercooler in front of
the rad and then sort out any cooling issues by sucking air out of the bonnet with appropriate vents.

But you are trying to force air into the same (rear) section of the bonnet. Airflow is the key.

how can the air be forced in through the side panels? surley with a rear opening they act as a vacume?? pulling all the air out of the engine bay
rather than it circulating in the engine bay????am Imissing something???

The air flows in from the front and will try to leave by any means possible, so it may actually be flowing OUT through the IC vent (Rathe than IN as I
assume you want?), as well as out the side.
Whilst it may be a bit more expensive, have you got space for 2 smaller IC in the front somewhere? Ie use a deep, but narrow rad and put ICs either
side, or just one deep one next to it, splitting the better cold flow you get in the nose cone.

anything at the front is not possible, if Ican duct the air from round the intercooler down the tunnel will this help??I have air from the front and
air from the scoop, I thought that this should vent out of the side panels and tunnel.........the intercooler is tight to the bonnet, so for air to
escape through the scoop it would hve to pass thrpough the intercooler.
other option is a fan on the bottom of the intercooler????

Whilst there may be air flowing through the IC, if it comes from the engine bay it will be quite hot, so probably won't help much. Otherwise any
airflow is better than none, so as long as you can force air to travel from the front, through the IC and out somewhere, then jobs a good 'un.
Forcing it down the tunnel will also help keep you warm.

leave off the engine bay side panels altogether as you don't even need them. Once mines though it's SVA their in the bin.
