Hi Garrick,
In what way do you discover you need this:
"32 MM CB mod rings . I Guarantee you need these. Either CB ones or home made"
I tried them on my single weber turbo engine, and without them the engine runs much better.
Turbo dells.

Re: Turbo dells.
After I got the twin dells working properly in N/A mode I refitted the turbo pipe work and tested it.
I got no boost enrichment AT ALL. The AFR gauge showed leaner and leaner.(no top end fuel).
I fitted just the Mod rings by themselves re tested it and got boost enrichment with an AFR reading in the early 12's.
You wont need a big main when you use mod rings.
My mains are only 140's.
I'm using N/A size jets for round town driving and the mod rings/my own E tubes and extra fuel pressure from the boosted fuel reg for on boost driving.
I've increased the size of the float bowl vent in the carb top to give to bowl a better pressure signal.
