I never thought pressuring a SU carb with a turbo was a great idea.
The naturally aspirated MG Metro (which I had) regularly needed tuning, but the MG Metro Turbo was a sod to keep in tune by all accounts.

The move to injection and electronic management solved those issues. Jules

I think that the early SU carburetor turbo systems were a little before their time.

Even after enclosing or sealing off the damper, there were too many variables for the physical, analogue system to handle, and as Jules says SU/Stromberg carbs needed constant attention. Later Fuel Injection and Computer Control allowed easier(?) control of mixture etc.

Some people don't deserve help.
I can't stand it when someone doesn't get the answer they want in a couple of days, then demand to have their account deactivated.
It's almost like it's a right to have all questions answered accurately and immediately.
I haven't go the time of day for those sorts of morons.

Nodge, he sounds like the type of guy who'll slag off the Freelander 2 and Land Rovers in general as being unreliable pieces of s41t because he's an impatient a55hole.

So many people with problems seem to forget that we aren’t a help desk and just a community of owners who have experience that we are willing to pass on. This new users problem was one that no one currently around had met before so could have added to the community knowledge base but that opportunity has been lost now.

as above, if i cant find the answers on here i look elsewhere , not get shi y with it, and if i can help somebody with something i will. 2009 FL2 S now gone

I did a review on a new vacuum, years later on the vacuum I chucked out someone in a completely different timezone basically demanded an answer instantly. I happened to be awake & said borrow a vacuum from your neighbour.

I have no idea which forums the OP is on, but one would be hard pressed to find a forum with the depth of knowledge of this one, & polite.
