Quick Question For Supercharged Ss Owners


Recommended Posts

There is no reason for a supercharged or turbocharged vehicle to get any different mileage than the same N/A motor under cruise/part throttle; my truck has a large Paxton blower and gets stock mileage (except for the blower & injectors & MAP sensor, the engine is still stock). The Radix (positive displacement) blowers do actually improve efficiency, we've always seen MPG go up 1-2 MPG. If you have a forced-induction vehicle and the freeway cruise MPG is worse after the blower/turbo install that is a direct reflection on your PCM tune; if the WOT mileage is worse, well then that's a direct reflection of your "fun factor". :driving:
