Done a quick search on these, and everyone talks about em, however one thing I've never heard anyone talking about actually running them. Anyone running these, and how much boost are you using if you are. I'm not a Syclone/Typhoon owner, but I've been researching a turbo 4.3L project for about the last 4-6 months and I'm thinking the project is a hell of a good idea performance wise. If it comes down to it I'll find a worn out motor, throw a set in em and throw as much boost as possible on em and see what happens to em, but I'd rather not re-invent the wheel if at all possible.
