How Much Heat Wrap?

[Snapperpaul]

I'm in the process of installing the new engine, on removing the manifold the old heat wrap virtually fell off. So how much do I need to wrap a Robin Hood 4 branch from head to where it exits the car side panel?

Also had a Sierra engine mount fall in half if anyone has 1 or 2 laying around.

I think I used 1 roll of 50mm 2nd time round.

The first time I needed a bit of another roll, so the second time I did not wrap so closely

10 meter roll?

[Guest 2b cruising]

I used almost 6 meters wrapping a crossflow four branch under the bonnet.

I wrapped it close bound and took no shortcuts.

I used stainless ties on it and had no secondary problems apart from bluing of the external pipe on the first run out.

If you want to keep you pipe from 4 branch to silencer shining, don't use,wrap. Just plenty of bonnet breathers.

It's grey/brown as it is, wrapping it does it a favour

10 meter roll?

aaaah. Sorry Paul. Can't remember.

Useless bit of info from me lol

I haven't got any wrap on mine at all (2.1 Pinto) but I have got some around the clutch cable that passes between 2 of the pipes. It been like that for the 13 years i've had the car with no problems. (so far).

We used 50mm titanium wrapping overlayed by 25mm. Total of 15 metres under the bonnet and 5 metres outside of the car to cover the whole of the manifold.

cb750 thanks, I've ordered 2 x 10 meters that should do it.

Still looking for Sierra engine mounts, they seem to be both rare and expensive.

I used the long Cosworth clutch cable that loops all the way past the manifold so no heat issues there

The early sierra mounts are rare!

2 styles of sierra mount. which are yours ?

[cb750]

Paul, have you seen these? Ebay 120878318228. A bit expensive for 1 but they are new and poly. I adapted landrover mounts to fit mine, the studs needed extending and a mounting flange made but they seem to work well.

[Snapperpaul]

The mounts I have are similar to the 4x4 mounts at least £30 each second hand,

I've bitten the bullet and ordered similar to the ones above, I got 2x engine mounts and 1 gearbox mount for just over £100 delivered.

If the Sierra mounts are that rare and expensive I may sell on the remaining good one.

I could mod the broken one and use the large rubbers with a thread either end but that would add time and I've already lost a month and a half.

So far I have spent £330 on repairs and cooling upgrades

Ho hum

18 ½ meters is the answer

1 roll did 2 pipes from manifold to where it exits the body side and back up to the manifold on an adjacent pipe, did the same for the next pair the used a meter to wrap all four pipe bear the exit hole
