Harrop Engineering - Thunder from Down Under

Thunder down under From

You may not recognize the name Harrop but in its home country of Australia, the Melbourne, Victoria based company is more than well known. Started in 1955 by Len Harrop and his wife Elsa Harrop began producing weaving machines and kept their customers happy by using good old Australian ingenuity and working hard. Business was good and savvy Harrop decided to expand into other industries such as industrial food-processing equipment, heavy haulage and earthmoving accessories. In 1963, the Harrop’s son, Ron, joined the company and brought a new vision. Ron was handy as a youngster and by age ten, he was welding up go-karts in the back shed. Once he reached his teens he got into cars and built a MG TC powered Morris Minor. He then left behind the British Morris and moved on to Australian cars with a Holden EH before building his now famous FJ which dominated on the drag strip. Solving problems and being able to engineer the solutions inhouse is what has made Harrop Engineering the powerhouse it is today in the Australian automobile arena. In December 2008, Harrop become part of the Adrad Group of companies, an Australian family owned company whose speciality is all sorts of radiator manufacturing. The Harrop name has not disappeared with the acquisition as third generation Tim Harrop continues as Operations Manager.

The Harrop range of Superchargers utilise Eaton’s Twin Vortices Series™ (TVS™) technology. They are a Roots-type positive displacement supercharger designed to deliver more power and torque for uncompromising, high-performance driving. The TVS™ supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a wider operating range. It’s the same supercharger rotating group utilised by the new C7 Z06 with factory supercharged LT4 V8 engine package.

With positive displacement generating boost from low in the RPM range Harrop has developed an electronic bypass control valve that integrates with the ECU Calibration supplied. This strategy for managing boost transition develops impressive torque low in the RPM range and carries it through to redline, dramatically improving the mid-range performance where the driver will feel it the most.

• One thing Harrop does a good job of is developing parts for particular cars. To make sure they properly engineered the products for the E92 and the BMW S65 engine they bought a M3 to use as a test mule. That meant the car would see all sorts of use, everyday driving to fast road and the occasional track event. Their products have to be capable of doing it all and this M3 was their way to prove each and every component the company built for the BMW. • An ever evolving project, the Harrop M3 is kitted out with the following products. • Harrop TVS1740 Supercharger Kit is the world’s first positive displacement supercharger for the S65 V8. • Harrop Ultimate (BBK) Brake Kit – 6 Piston Front, 4 Piston
