If O.D of hose is 29mm as stated above, the I.D cannot be 26mm as it gives a wall thickness of 1.5mm. You can easily squeeze this flat with 2 fingers.
From Parker hose catalogue for coolant hoses, a hose with 30mm O.D. has an I.D. of 19.1mm.
Hope this helps

if this is so, then I may just have the solution! Let me get back to everyone.

Hello

Yes sorry not allowed to divulge mine.

Inline thermostat as per that link to the US one for $66 is exactly what I was going to install originally though, no divert needed!

The 3-4" of dead leg won't be a problem with the turbulence, besides, this isn't potable water hose, we don't need to worry about legionella forming in stagnant water!

If the hose is 26mm ID, 1" is 25.4mm so I'd go for a 1" inline t'stat housing from yank, assuming the hose barbs are enough to retain it, and some decent jubilee clamps. Cut into the long hose as above.

Great, secrets, fantastic. Might have helped if you had stated that in the original post...

Point us in the direction of a 1" inline stat and were all laughing Thumb

I did state it in my original post, and so did the previous poster in this thread...

I was going to DIY and use one of these options, either adapt down to 1", blank off the bypass, or figure out which other manufacturer's factory part was nearest to suit 1" hose;

Audi A8 one, looks the correct length and probably of the same materials as Porsche. And for less than £15

It's all down to the diameter,

I was having a really posh moment, and thought about using a 12v solenoid valve, with an inline temperature switch adapters, like one of those radiator fan switch, that way, the opening temperature can be changed easily, or even over ridden from a dash switch when in a 'race' (track) situation). Probably a using a heater circuit divert valve. Food for thought.

Way,way ahead of you. Found solenoid valves etc but sometimes if the solution is so expensive for ( road use or track day only ) then it is more sensible to take the cheapest option. If we have created an issue by adding the centre radiator, then remove it! I am still pursuing the stat solution and have parts on order but may in the end just blank the rad off or rip it out again and put it down to experience. I know Clarkson said the 911 is a triumph of engineering over common sense but I refuse to go down the same route!

There you go, £64,94, just thread a couple of G1" barbs into that and you're golden!

1" connections, 12VDC, 100 Celsius rated, NC, industrial quality...

When I'm pulling off the toll roads and queueing for the car park into LM2020 I will be thinking, boy I can't wait for my centre rad to get some flow and stabilise those bank 2 thrust face temps.. Wink

Beers!
