Thinkin about gettin me zorst manifold ceramicly coated! but dont wanna spend the fookin wedge on it if it aint gunna stop the manifold from crackin!

so will it stop the manifold crackin!? or am i forever stuck weldin the thing cause it was porrly made!?

 

where is it cracking mate?
have you got a damper going down to the gearbox to take the turbo's weight?
i doubt coating will stopp the cracking, you need to sort out why it is stressing first!

 

Sorry but in most cases tubular manifolds and turbocharged engines don't go toegether very well!! Ceramic coating won't help your cracking problem.

The only solution to cracking is to use the correct design and materials for the manifold as well as correct turbo support. You must consider areas of expansion, vibration and flex when the engine rocks in order to develop a reasonable reliable solution.

 

it seems to crack were all 4 go in2 1! i have a gearbox suport! which has helped but it cracked again ton monday! (under bonnet flamer kit )

so no point in gettin it coated them just helps with temps!

So karl would u say poor materials/design!? i.e. not a lot I can do about it!?

ANywhere else I can support it!? would it help to suport the down pipe a bit more!?

 

Yup, its doubtful that its the heat causing it to crack, its the material the manifolds made from.

 

Is the turbo supported from above in any way?

 

To be fair you can't beat the std ERST cast manifold. It's so damn durable, NEVER fails and you can get 350bhp from it with the correct turbo and down pipe.

 

think its a combination of poor material\design

there's a fook loads of weight on that manifold the stress's on the welding joints must me huge

Weight of the Turbo
Weight of the Exhaust about 60-70% of it.
Weight of the manifold itself.

put that together with the stress's of movement and bingo

its a CRACKING TIME

 

yea but ryan, you used to be a gymnast

 

no Ste it aint!

I know Karl but it looks

 

have you got a flexible section on the down pipe anywhere mate???

that might help

 

foook it i knew i shouldnt have said anything.

Yes the manifold s supported by a bar of the box.

not the turbo

 

no flexi which is a bit of a coont but then i dont kow if ya would get 1 in!

 

what about the heat wrap!? could that cause crackin i heard a bit about this!?

i have got shed loads on it!

 

 

alright drop it already,

must admit though i looked pretty good in lycra

 

bet you was one of the ones with the ball and the ribbon
