The Italian manufacturer Innocenti whom started producing cars in 1920 but is most famous for it’s Lambretta scooters of the 1940s to 70s started making their own versions of Austin’s best cars in the 1960s. Each of the cars on the right is the Innocenti version of the Austin car on the left. The Minis were still called Minis but the Sprites were called Spiders.
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.
This Sprite arrived in typical fashion exactly as you see pictured here. The owner has decided to put on hold the 1958 Sprite we started and move the racing engine and suspension over to this car instead and then restore the other car to a more factory condition. This car has signs of being an old race car with the roll bar cut off near the mounts and when finished will be faster than ever.
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.
Both of these Land Rovers are 1972 model Series III 88s but one is an original right hand drive and the other is a US spec with added reflectors and slightly different lighting configuration. After some testing on the dyno the advantage of the add-on overdrive units is clear and with the overdrive the trucks could travel at 80 mph if you were brave enough to do so.
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.
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.
The Lotus engine is rebuilt and sitting again now in the 1973 Jensen-Healey. Without the intake manifold and carburetors mounted the Lotus 907 engine looks tilted 45 degrees. This early Jensen-Healey is only a few hundred before they made the first big revisions to the model. The later Series II and JH-5 models seem more common at shows.
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.
