firewall at bulkhead

P.S. from the photo,.... Wow, gold leaf heat shield!... Shug really did show that car some special kinda love.

[SteveJB]

was thinking of doing the paint job to match the heat shield

[Ferg]

You joke, but that could work as s colour scheme.

It looks like somebody has swallowed some gold and then, .... use your imagination

Hi,
It is well worth switching to the S2 manifold and downpipe because you can fit the S2 heat shield to it - this is pre-formed Nimbus-like material that bolts to the manifold (rather than the bulkhead) and is easy to replace when it falls apart. As a side effect the downpipe is easier to replace and the Lambda sensor is better placed for access also.

Robin - this is the old Shugmobile, it's got a 4-2-1 manifold, so an S2 bag of bananas would be a pretty retrograde step

tip; the S2 heatshield works on a 4-2-1.

Robin, never wrapped an exhaust, but generally hear poor things about it in the longer term?

Having cooked 3 alternators since fitting the S2 heatshield with a 4-2-1... not convinced it's the ideal solution by itself.

Now looking into wrapping or coating the exhaust too.

There is an additional heat shield that lives between the manifold heat shield and the alternator:



It's items 23/24 in the picture. Do you have that fitted too?

Cheers,
Robin

Not sure Robin... will pass to Mr M and have him check.

He does think there's scope for more heatshielding in there so hopefully this or another route will solve the alternator frying.

Whatever you do don't get the EP alternator heat shield. It comes flat pack and I could never work out how to fold it up to make it the right shape. Ask Craig to get Harry to weld up a custom steel heat shield

Cheers,
Robin

I think that wee heat shield is the key to saving the alternator. Think we replaced mine when we did an S2 manifold upgrade.
