No Chip, i just found it by accident while looking for summat else.

BUT the spec DOES work in the way i described, as I know someone who specialises in twin charged engines and have very detailed explanations of what happens and why, how it should be done, etc etc.

And although that engine is just mad for the sake of it, it will work suprisingly well, miles better than you seem to think.

Mainly as twin charged engine characteristics arnt commonly known, and arnt the same as n/a, turbo, or supercharged, engines.
