Intercoolers?.....
Discussion
Hi Peeps...Just gathering some info as regards to the supercharger..Im fully aware that the under bonnet temperatures are going to rise considerably when the blower is fitted..I do have some plans to deal with under bonnet airflow but the air from the blower to the plenum is going to be warm/hot..Although im not sure of the actual air temperature after compressing?..Now the way the pipe work is set up means that there is very little if no room to incorporate an intercooler post-blower - pre-plenum..Or at least without re-fabricating..I was thinking of either a Co2 kit that incorporates a valve sytem that is linked to full throttle in to the pipe going into the plenum..Or a cool tube set up which would mean cutting the pipe down..It may not be needed, Its just in case it does..Cheers...Ziga

Hi Graham..That was a thought but the pipe work is expensive to adapt what i have..Maybe the cool tube would be better as the air will be rushing past a chilled coil rather than a valve or through a rad..I suppose it is the cleanest route..I might not need it yet but cool dense air is good for any engine!..And it will only be linked to full throttle as not to use all the gas up in one drive!..It will be interesting once the blower is fitted to measure under bonnet stationery temperatures..Cheers..Ziga
Perhaps you can see it as a first step to not have an inter-cooler..., and deal with it later.
At least that is how I think about it, as the plumbing etc can be done later.
You have big changes going on already and you will have more power anyway.
It is probably just me to keep things always as simple as possible to come up with a reply like that.

Wheather you need the intercooler or not, depends on how much power you are after and what kind of boost pressure you will be using. Unfortunately roots-type supercharger makes a lot of heat (compared to a centrifugal or exhaust driven turbo). If intercooler is too hard to fit, one solution might be using water-injection. Aquamist makes good kits. I have used them in my cars. Adding methanol to water makes your engine life a lot easier in long run.
Just an idea to think about.

THe SX350's and 400SX's manage without an intercooler.
I don't want the hassle and extra pipework one would entail - plus an intercooler saps energy out of the system - I'm thinking water injection just before the supercharger will be my next upgrade.
Have a look at Ozzy Adam's thread on his air box - if you arrange the air intake appropriately you'll get the most benefit.

I'd tend to agree. My other toy is supercharged as standard and the only available upgrade is a smaller supercharger pulley (to improve responsiveness I'm told) and a larger intercooler to increase power. I get the impression that there is some physical limitation/wall that is hit, preventing adjusting the wastegate blow off making any improvement.
Cheers Tony..Mabybe the cool tube is a better idea then..It's basically an alloy tube with a coil inside that is super chilled with refrigerant when you floor it and gradually when you dont..This would be easier to fit and maybe a good edition to the initial cold fed air intake..Cheers..Ziga
Ziga, that pipe work setup is ideal for a charge cooler setup 
You get the best of both worlds with them. As the pipework stays the same length for the boost for instant throttle response, and you get the intak air cooled as well
Although the one failing of most setups is the lack of surface area on the chargecooler radiator

Same here - I run a cheap (£5) multimeter and a thermocouple into the engine bay which I can place in various positions.
When running WOT the post-supercharger air temperature is around 60-70C with about 25C ambient and no air box. I don't think that's excessive - remmeber this is a supercharger, not a turbo.
As I said earlier - the intercooler will rob energy from the system. This energy has come directly from the crankshaft rather than being scavenged from the exhaust gases like in a turbo situation. You're far better off keeping this energy, getting cool inlet air, and adding water injection which cools the charge but keeps the energy rather than losing it.
