I drove Mike Hodge's B&B to 2015 London Cobra show. He has a B&B hardtop, Keith Craft 408 with Quickfuel carb. TKO 3550, 26" tires and 8.8 with 3.55 gears.
Cruise at 2000 rpm for 500 miles. 91 and 93 oct ethanol crap.
It got 17.23 mpg. I used my GPS to check the mileage. His odometer is off 8% but only one to three miles per hours on the speedo.
We were all surprised. Normally he gets 14 mpg.
