hottuning/raceland manifold?

Mine was spot on fit wise. And quality was fine.

Are you sure you really want to wrap the manifold.

 

everyone else seems to be wrapping their manifolds, so why not...

 

Would the bulkhead not rust due to burned paint, from the heat from an unwrapped downpipe? I've seen it happen on a g60 mk2 with a standard downpipe and no heatshields on the bulkhead..

 

burnt paint? somehting would have to be very wrong with the set up for the manifold to get that hot!

 

I dunno about that now, this guy has the car running like a dream, he's clocked up big milage across europe in it as well.. But the bulkhead is all rusty, where the paint has burned away..

 

Not usually a problem at all. Forced unduction maybe, esp with the timing retarded.

 

could the heat knacker the steering UJ bearings, boil the grease away etc?

 

bubbly paint on my bulkhead on the mk2 trackcar and its gone rusty, 4branch is very very close to it..... not saying heat was the cause but it could be.

 

6 to 800 deg according to a mate of mine, think ill be wrapping mine

 

I've seen a couple of cars with holes near the manifold/downpie area, think seb had one on his race car if I remember correctly....

not definative that it was caused by excessive heat but it is logical to make the connection considering the way in which rust is most easily formed i.e. unprotected metal + moisture + heat

 

Wasnt corrosion a problem on early mk2s a problem in that area due to the lack of a bulkhead heatshield which was later fitted by vw?

I know the car Drunkenalan broke had gone in that area although cant say ive ever really noticed it on any ive broken

 

On the abf engines, there is a fireproof 'curtain' hanging down from the heatshield on the manifold to protect the rubber steering boot/driveshaft.. So if Vw thought there was a risk, i'd say possibly.. I'm sure i've seen a boot covered in downpipe wrap at some stage also..
