HOLDEN EFIJY
When GM Holden made the decision to produce the wildest concept car ever, Holden designer Richard Ferlazzo, the brainchild of the “EFIJY” approached Harrop Engineering to gauge interest in the project. With confidentiality agreements in place, we discussed at length our enthusiasm to be involved in producing many of the components required. This was a perfect opportunity to showcase our capabilities to a worldwide audience.
More than 20 suppliers and designers offered their time, parts and expertise to build the car over 12 months. In 2005 Holden estimated the build cost to be over $1.5M; today many consider EFIJY to be priceless. The car is based on the stretched and widened underpinnings of a C5 Corvette and features a Harrop polished LS supercharger assembly together with the finned billet rocker covers for the 6 Litre LS2 based HSV engine. With 480Kw of power and 775Nm of torque, it is almost 11 times more powerful than the 45Kw (60hp) engine in the 1953 FJ Holden.
Harrop also produced the 22″ diameter rear, and 20″ front, 2 piece, billet outer and spun inner rims, together with intricate 5 axis machined billet hub caps. With such high levels of powertrain performance our Ultimate Brake Kit featuring 15″ (381mm) dia. front discs with 6 piston calipers and 14″ (355mm) dia. rear discs with 4 piston callipers were the obvious choice to achieve necessary braking performance.
