Exhaust side pods exit.
Discussion
Hello mate, as usual excuse me for my spaghetti English.
Here in Hotaly (hot Italy) probably my new toy (Can Am 383 supercharged) have some heat problems.
The car have already some issues: clam paint in 3 or 4 point ( 1/2 inch square ) it's go away.
I have think to a reposition of silencers and exit in side pod with a lot of nimbus to protect fuel tank and rear clam.
No one have try this before?
Thanks, Alberto.

I would perhaps look at thermal (http://www.zircotec.com/page/exhaust-system-coatings/60) coating exhaust system and (or maybe try this first) perhaps using http://www.zircotec.com/page/--zircoflex-iii/150 to wrap silencers
Hiya from Wet UK! I've just got my GTR on the road and I've had similar problems with overheating. My whole exhaust system is coated in Zercotec and the clam is also lined with Zercotec sheets. Despite this I was still getting damage to the paint above the exhaust headers. Steve Smith has fitted a set of clam vents for me and it has dramatically lowered temps.
This may be of help? A bit more detail than my original reply.

I added a pair of vents to the central scoope, which puts them almost directly above the headers and, as heat rises, is effectively the topmost point of the clam.
They did the job - but then I didn't have a supercharger to deal with (that said, my headers weren't ceramic coated either).

There are pics of srrecks recent addition posted recently which follows Stigs suggestion too.

The previous owner was always on here with "heat issues" and how to manage them, he obviously didn't succeed!
I suggest you trawl through the last two years posts on here and you will see what has been discussed.
I believe the car was converted to Evans waterless coolant which WILL make the car run hotter by Evans own admission (and the laws of physics) but will not boil over as it has a much higher boiling point.
I run a similar Procharger set/up to you in a GTR and have no such problems with heat.
I have an open mesh-less clam vent at the rear to reduce bay temperature.
Zircotec the exhaust system. this is the number 1 bay heat reduction solution.
Additionally I would get a feel for the car and assess whether you NEED the power as it is set up.
If you think you can take a power reduction then a larger pulley on the charger will lower boost and therefore heat.
I have an LSX motor in mine and it is capable of stupid horse power however I chose to limit it at circa 550 BHP.
As a result it drives on road beautifully and still with the rush of a pressurised intake.
I run 2-3 psi only.
Supercars choke in my dust!
Do you have pictures of the exhaust setup and engine bay.
Also do you know what type of silencers the car is running... some 'retain' a lot more heat than other designs, on my Ultima I made the exhaust longer by having bends in it and changed to a straight through silencer similar to what I run in the noble which made is quieter and retained less heat in the engine bay.
Thing is, if you struggle to keep the car 'cool' when just running round with odd blast, then it will have major issues when you use it hard.

As Andy said, if you could post some pics that would be very helpful. Be interested to see how close they are to the bodywork as this shouldn't really be an issue unless they are very close. Could also be down to running an incorrect map and having fuel burn up in the headers/exhaust.Also do you know what type of silencers the car is running... some 'retain' a lot more heat than other designs, on my Ultima I made the exhaust longer by having bends in it and changed to a straight through silencer similar to what I run in the noble which made is quieter and retained less heat in the engine bay.

Removing the grill mesh, adding side scoops, using gold reflective heat shield and opening up more of the clam with vent panels are all options if the exhausts are already coated and the car is running correctly...

......I have fear silencers are collapsed.... .....
If they are factory then there is nothing inside to collapse.As you can see the incoming pipe is sealed at the far end of the box. same for the exit pipe. Both these pipes are full of holes so the gasses pass across the box to the other pipe passing through the packing (which may now be non existent).
