Haha, is there a particular flavor of gatoraid that comes in a 20psi-rated bottle? :D

Mine is is a separate, small pipe post-IC. It's relatively thermally isolated from the intake manifold.
Patrick's car we put it right in the lower airbox.
In the pontoon it might become more of an ambient air temp sensor than intake air temp.
I believe Arran from Deloreango might have a used repro if you're still interested.
I do, but it isn't suitable for pressurised systems.
Over here there a few people using a Volvo plastic tank, Volvo part 1276040 (replaced by 3547466 ). This requires no drilling as the bracket can use the existing mounts - just a slight modification to the hose.
One idea is to move the tank into the pontoon and cut a hole for the pressure cap. Then connect an overflow tank to the overflow and keep the header tank filled and watch the level in the overflow tank. That is what Lotus did and they put the overflow tank in the R/R wheel well. Another thing Lotus did was put a fan in the engine cover controlled by a thermostat to reduce heat soak. On the V-8's they also put an electric recirculating pump in and the ECU controlled it and the rad fans to get rid of heat soak. For more passive solutions use heat shields and heat wrap tape. On old Jaguars they porcelainized the exhaust manifolds to reduce radiated heat.
Thanks for that! This tank was actually on my short list as it seemed like it would work for all the above reasons.
Do you know if people are using the green 1.5b cap? I saw a reference to a very uncommon white cap rated at 1b but a quick search came up empty.
The cap is 1357776 - which is the correct 15lb / 1 bar one. Obviously you don't want the 1.5 bar one. Colours do vary, but generally it is white, yes - some aftermarket ones are black, I think some are even yellow. Generally the green ones are 22PSI/1.5bar - you don't want that...
Although it is used on the various normal Volvos (the usual ones that we are all familiar with) its main use these days is on a boat engine, and this diagram might help - http://www.marinepartseurope.com/en/...90-15204B.aspx - in some cases you will need to buy the bracket separately - I can't remember off the top of my head how it attaches on the car - as mentioned the only real issue is the hose outlet which just needs a reducer to get to the correct size.
First, I like that tank Arran posted because the mounting would be simplified, at least compared with what I had to fashion to make the Volvo 940 tank work.
Second, I've been running the green cap for about a year now. If you have an original car with original hoses, you may be more likely to burst one, but ideally the cooling system should hold much more pressure than its normal operating pressure. There isn't anything different about the hoses and clamps and radiators used on the green cap-designated cars.
