How bad is gas mileage on...
<strong>a heads & cam package, stroker, turbo, super, etc.
What the numbers?</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Don't know about the heads/cam or supercharged setups.
The best mileage is on a turbo setup, and the worst is on a roots blower setup. This is referring specifically to normal, non-racy driving.
