Whatever the shyt is that's got hold of my mate France I commend thee to leave...
Is the extension long enough to go down Sean's long primaries!?
France, Germany and Mr Juncker have just wooed President Xi Jinping....we're not leaving anything.
More than adequate if you stick it up both ends........
Fwiw, I used to have a shield from head to chassis but it really got in the way.
I swapped to the per-carb heatshields you can get for Webers and Dellortos a year ago and didn't have any heat related problems last year.
These are they Jason. I added a layer of heatproof cloth too.I can't remember seeing a car where the exhaust manifold was 'boxed' in, thats what my comment was about, along with a couple of the pics providing a hard link.
It'd be interesting to see your per-carb setup also. Effectively the same as the tray you get with some aftermarket carb setups?

They don't look much, but without them or the full shield I had fuel boiling in the carbs. No probs at all now.
I'd bet that tray will be fine.Nice and simple, my oer's came with a full tray as part of the kit, must work exactly the same?
IMO if you mount the heat shield to the engine and then to the chassis you will get differential movement and continuous flex in the heat shield. It will generally flex at its weakest point all the time. Eventually the ali will break at that point. It's easy to test this out. Just get a thin piece of ali and bend it back and forward a few time. You will start to see a fracture line and then it will fail on the line in a very short time.
I have used that same material for my heat shield and it is very easy to form around the manifold and then us the stainless steel tie wraps as suggested to just keep it in place.
Hmmm this was a concern of mine, thinking I prefer my orginal idea of the stainless steel cable ties again now. Pressume you never had any noise/rattles from this method?
Equally if the Ali is as Rigid as I'd expect then making a bigger version of the stock heat shield with this matieral could work just as well and doesn't need to be supported at the bottom.....
I can show you pics of the oer one, its nothing flash, just a complete cover for under the 3 carbs.
What we all need are mild steel systems, they make more power and don't radiate heat as much
What we all need is to get a life !!!!

Thanks...for pointing out that I've wasted 10yrs of my life.
Ok, thanks.
Except that Steve Kiddell, for whom the extra % of hp was worth chasing was running one....and Dave Rebello, who also boasts max power reccomends them to customers and has just bought 5x !
