Fine for coolant

Fully agree about the silicone pipes blowing off, that’s why my mate had a couple of welds put on the end of the stainless bends to help bite into the pipe.

Once done didn’t happen again, IIRC two or three spots around the bends about 10mm back from the edge

Should have clarified when I mentioned "any sort of boost" I should have specified high boost ( 25+ psi)

Yep, ideally in high boost applications murray clamps are the go, failing that , intercooler specific worm drive are better at holding than t bolt.

We were constantly blowing hoses with worm drive clamps at anything over 20psi on the 4bd1's, never blew one off when we went to proper clamps (the ones with the springs)

Constant tension clamps?

There's a couple of different versions depending on manufacturer, some use a coil spring on the tension screw, some a wave type spring between inner and outer bands but the principle is the same.

It's what I've used on my hoses

Yes thats them, the coil spring version.

the clamps you are referring to are called Mikalor clamps , available in a huge range of sizes and material.

my D2 had mikalors on nearly every hose as nearly every other clamp broke......

Either that or they cut through the bloody hoses.

yes you can get wide Mikalors with a rolled shoulder so it doesnt cut the hose.
