Local Datsun guru Ed brought his Datsun 280Z over for us to run his car on the dyno and gather information useful for tuning future 280Zs. He had spent years tuning this car by hand and the dyno showed that he had it spot on.

1966 Marcos 1500GT
The GT body style was first introduced in 1964 with a Volvo B18 unit with overdrive gearbox and De Dion rear axle. In 1966 they switched to the Ford Kent “Formula Ford” engine. The plywood chassis was glued together from 386 separate pieces and was not only light and strong. Although most people have never heard of Marcos which ceased production in 2007 you have heard of the drivers who raced them. Among the drivers were Jackie Stewart, Bill Moss, John Sutton, Jack Gates, John Mitchell and Jackie Oliver, as well as Jem Marsh.
Might Be Adequate
Most with the Least
The DynoJet is a great tool for more than just seeing horsepower and torque numbers especially on a car with a small engine. Using the DynoJet on this 1953 Ford Anglia we can scientifically check how the carburetor is functioning, ignition health, top speeds in each gear, and accuracy of the speedometer.
Tale of Two Octanes
Running this Shelby GT500 Super Snake first on 91 octane pump gas and then on 98 octane Sunoco racing fuel confirmed what we saw two weeks ago with the GT350 that these cars will greatly benefit from higher octane fuels. The Super Snake saw an increase of 46 hp giving it around 740 gross horsepower.
50 Years Coming
Fifty years after the original Shelby GT350 a new one is now available in dealerships. Ford rates this 2016 Shelby GT350 at 526 hp but it wasn’t until we drained out the premium pump gas and put 98 octane Sunoco race fuel through it that we were able to see those numbers. To our surprise switching fuels netted a gain of 25.5 horsepower with this car.
Anglo American Hemi
We have had the DynoJet for just shy of a year now and by the end of the year it will have seen a fair share of interesting makes and models. The DynoJet is great for much more than just finding out how much power or torque a car makes. You can analyze the fuel to air mixture, ignition condition, finding leaks, engine break-in, and even aero dynamic effects on gearing.
Birkin S3 Lotus Super Seven
This new Camaro Mustang Challenge build was just finished and is here for inspection and certification. The engine was making much more than the owner expected and the restrictor set wouldn’t bring it down to spec. After fashioning a custom restrictor this car is right on the mark and can be seen at NASA events very soon.
