Supercharger + Black Smoke

[TJW]

I have had my ST Sitting up a while and since starting it and replacing a perrished pipe from the Supercharger to the bypass valve , its been bellowing out black smoke and wont rev.
Thinking i need a new S/C.
I have the belt off the S/C and want to run without it.
The car runs a bit jumpy when the S/C Light comes on. How can i fix this?
Also the turbo can b heard to create boost and dumpvalve is working when i back off but i am not getting any boost into the intake! Thinking bypass valve to be the problem.
Can anyone give me a quick fix that doesn't involve removing the bypass valve? ie swapping vacume pipes or something.

Swap the vac line between the turbo outlet and bypass valve(before the Y in the pipe work) and the one underneath the Intercooler. She should boost away grand then if the rest of the vac lines are fitted correctly

Thanks Baz.
Im away till tuesday. Ill Try it then and let ya know how i get on.

Sounds like you have a boost pipe disconnect somewhere (not a vacuum pipe) the AFM is metering air which is not getting to your engine thus its chucking in fuel and making the black smoke.

Check your main boost pipework.

I really think its the supercharger. Its really noisy. Even on idle.
Thinking it needs rebuilding.
Anyone in ireland looking for a March ST for parts or restoration???

Superchargers don't run at idle

That car needs looking at properly. I suspect all the pipes will be all over the place.

i always thought superchargers are belt driven from the crank therefore run constant even at idle. ?

 

[Ed]

Not on the ST it doesn't. Its on an electromagnetic clutch.

It runs like an air-con pump with the electro magnetic clutch when the sig from the throttle postion sensor ( depends on engine load and throttle postion) its sends a sig to the s/c to engage, same on the 4agze Toyota engine for the supercharged levin
