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.

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.

Uncommon Dyno

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.

CMC Restricted

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.
