Therefore requiring more IC capacity.

Most of the heat in the compressed air actually comes from the compressing itself not the exhaust heat. When you compress the air a by product is heat the more compression/boost more heat.
Heat transfer through the turbo from the exhausts is not the issue.
we could get picky here. The amount of heat doesn't, the temperature does.
the temp rises because you have X heat in Y space befor the compression. after the compression you have X heat Z space, (Z=1/4Y)
because the heat is in a smaller space the temp rises.
this is why we compress A/C gas to remove heat from it, and then let it expand so it will remove heat from air.
Compressing A/C gas heats the gas but forms the gas to a liquid, the job of the condensor is to cool the A/C gas, the controlled vaporization of liquid into the evaporator is what takes the heat from the air.
I wouldn't suggest leaning against the high pressure (liquid)side of a running A/C system.
Matt is correct the heat is due to the compression, it's how a diesel works, high compression causes heat, diesel is injected into the hot air mixture, hence the need for glow plugs and why worn out low comp diesel engines are hard to start.
Another example is the supercharger, no exhaust heat enters the supercharger yet they all produce high air outlet temps. They don't call EATON superchargers Heatons for nothing.
Plenums don't store boost, the throttle blade is before the plenum so there is vacuum in the plenum at idle and cruise. A plenum creates higher cylinder pressures as the mass of air, once accellerated continues to charge into the cylinder at increased levels, it does when under boost give each intake runner a high speed column of air to feed from.

the amount of heat still doesn't change. the temperature raises.
and yes you basicly said what i did about the A/C using different words.
we compress the A/C gas to raise its temp, the greater the temp difference the more heat will be transfered. We then vaporize the the now liquid, wich is also the point in the system that it goes from high pressure to low pressure.
Anyway my point was compressing air doesn't make heat, it raises the temperature. (large amount of heat in a small area)
Looks good, Could you please give a measure of the 'ready made' as it is?
On first estimate it looks good to fit up to a WRX motor (forester xt 09) top mount allocation without too much alteration to the air ram tunnel area. Here is a pic of the TMIC original.
(x3 on air compression = heat, a good example is the air in a compressor storage tank is warm/hot just after fill, but when you open the bleed valve, you should see water condensation around the valve, sometimes freezing even because air is reducing in density)

Thanks Matt

Page before has an estimate Awill4x4 has the first bolt on to work with, were keeping it simple so all been well final price for a bolt on 2-3 weeks away, it just depending on a project that may take priority for an M3 E46 BMW in the USA. The model I posted last week fitted and if we get the business this will be an urgent job.
This will be done a pair of cores at a time that way if any of the O- rings have been nipped on installation it will be easier to find. But not expecting any
I also have the headache of the E46 M3 1000hp BMW they are sending the blow off valve, cores, one T/B rubber and meth/water injector system that we are integrating into it.
Ok Every thing is coming together, Awill4x4 wanted a tool for pressing the hole for the feed out of the intercooler into the plenum, nothing too fancy as we are trying to keep the fabrication to a minimum and therefore costs down as well as be easily replicated.
The bottom plate will look a little like this but with only one hole to suit the 60mm flange. This is the test piece Awill4x4 gave me. It will have the same folds though to help draw the air towards the hole. It's a little hard to see but the center of the plate is about 20mm lower than the outer edges.
Finally got to give my cooler a little bit of a test 2day, I have the 35's on the car (cooper st's), still got 4.1 gears, 13psi boost on the standard DTS turbo with a 3 litre GU airbox, had the back of the car loaded up and a loaded up trailer (6x4) on the back.
Test hill, 4th gear, 100km/h and wasn't accelerating much more (plus I ran outa hill) and was holding 450C pretty steady.

TD42T shorty... got some bolt on and some custom stuff.

can you pm me a confirmed price on the complete minus fittings generic bolt on cooler for a gu ..... as benhl is in brissie too so may save on freight .... if price is right

Water splitters $100 a pair.
Until me and Awill4x4 have fabricated the bolt on one I can't give an exact price. I'm going to do a run of 5 so Awill4x4 can replicate a lot of the pieces.
Fabrication is not so much about materials but labour. So until Awill4x4 puts one together I prefer to sit on the fence a little. I would expect to be no more than $1700 including splitters. But hoping for less.
Heat exchanger such as Marin's $400 approx, Telstar Rad new with custom end tanks.
Davies Craig pump I would search the net or give Bursons, Repco, ect a call.
So if you go with hose tails and no bling, I would expect to have one installed and working if you fitted it yourself for no more than $2500.
As you can see the costs soon add up.
Well all the pieces are in place so I will stick my neck out and say $1500 with cores (while available as I have limited stock of cores) for the intercooler without cores $1100.
As above you will need a heat exchanger and pump along with the plumbing.
Looks like its the monster's 'forte' har har harrr
