I remember taking a test flight with jeff at Sebastian. He asked me what speed my cherokee cruised at. Then he slowed the factory Velocity to 130Kts like I cruised at in my pa28. Fuel flow meter shower like 3.8 GPH. I was amazed. Then at my normal GPH rate in the Pa28, the velocity was doing about 60 kts faster.... Explains why I'm building one... back to the shop....
