Regarding this -

I wonder why they relegated the battery to the boot when they could have moved the servo back to the firewall and kept the battery in its original location? Its a fair old big can on the servo, but still looks to be enough space.

Probably because it was direct descendant of the Twincam which had the exhaust manifold on that side. The first batch of RS1600's were in fact Twincam shells that had the engines swapped out for BDA's. Also early Mexicos were the same, so I guess it was the easiest and less costly route.

Eh? - It does have the exhaust on that side . . . . article-2094303-11888C87000005DC-867_964

Turn the servo round, can against firewall - loads of room! Anyway what's done is done - just curious!

Sorry, should have read; "descendant of the Twincam which "also" had the exhaust manifold on that side".

I guess it was initially mounted that way to get as far away from the manifold heat as possible to stop the heat from destroying the rubber diaphragm.

To mount it on the firewall would place it directly above the exhaust manifold and hot air rising straight into the booster and servo with fluid wouldn't be the best way to achieve the best bake performance. Brake fluid doesn't need a helping hand to get any hotter. Mounting it where the battery tray normally is places the greatest distance allowable in between it and the exhaust manifold in such a tight engine bay. Thats my best guess anyways

Yeah I suppose plausible answers - obviously the accountants weren't in charge back then as the cost of moving the battery, bespoke mount in boot plus 12 feet of thick copper probably far outweighs moving the servo and providing a piece of plate steel as a heat shield ! ! !
