RobertSmalls,
They said they didn't get a better BSFC. A turbo reduces BSFC unless you increase the octane required aka "premium" gasoline. I doubt they'd lie about their findings and while that's not impossible there is overwhelming evidence for worse BSFC with a turbo vs N/A even when comparing a smaller turbo engine with a bigger Natural Aspirated engine.

BSFC decreases with larger engine sizes and increases with faster engine speed. In a generator like the Ranger extender that makes the case for a bigger engine vs a small turboed engine.
