PERFORMANCE PARTNERSHIPS

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.

NIZPRO MARINE

In 2008 Yamaha released their brand new Offshore and Super High Output series of outboard engines and dubbed them the “Game Changer”. The US market instantly embraced the new Yamaha 6 Cylinder 4.2L Marine Outboard engines with many applications even running two outboards to maximise their performance potential. This triggered a new development program at Nizpro Marine with the goal to produce the most powerful 6 cylinder marine outboard on the planet, with less weight, drag through water and no additional service costs.

Nizpro Marine Director Simon Gishus approached Harrop Engineering and shared his idea to create a positive displacement Supercharger to suit the Yamaha V6. After many months spent analysing the complex packaging requirements and rotating group suitability for the application, a TVS1900 Supercharger Kit was cast and prototype parts manufactured to begin comprehensive testing. The heart of the Supercharger is an Eaton R1900 rotating group which is packaged within the Supercharger manifold featuring twin water to air charge intercooler cores. The Supercharger is driven by an 8PK drive belt and auto tensioner and only adds 55lbs to existing F and VMAX series engines. A key design requirement was for the Supercharger to fit under the factory cowl, a challenging task due to the limited packaging space left by the OEM but achieved with the use of a 105mm spacer. The Supercharger Kit was launched at SEMA 2017 on the Harrop and Eaton booths, winning a Global Media Award in the New Product Showcase for Best New Performance Product.

FORD (FPV) SUPERCHARGER PROGRAM

In 2009, Ford Performance Vehicles (FPV) approached Harrop Engineering when looking at options for a forced induction performance package for the FPV FG range. The result was a Prodrive developed Harrop Supercharged Miami 5.0L V8 engine, based on the earlier Ford Coyote V8.

The Australian delivered FPV FG range was boosted by a Harrop HTV1900 Supercharger Kit featuring Eaton Twin Vortices Series (TVS) technology. The Supercharger System was front drive, rear inlet and positioned under the intake plenum in the engines ‘V’, providing an integral high-efficiency plenum and runners. The Supercharger System also featured an inlet bypass valve that improved fuel efficiency and an electronically controlled ‘drive by wire’ and 75mm throttle body.

Peak power and torque from the Miami V8 varied across the FPV FG range, the FG GS and Pursuit were released from factory with 315kW of power and 545Nm of torque (maximum boost pressure was 0.40 bar/5.8 psi) where the top of the range FPV GT made 351kW of power and 570Nm of torque.

LOTUS UK SUPERCHARGER PROGRAM

In 2009, Harrop Engineering was contacted by Lotus Cars UK to design and manufacture the HTV1320 Supercharger System for the newly released Evora S which marked the beginning of an OE supply program that still exists today. Fast forward to the present and Harrop still supply positive displacement Supercharger Systems for the stout 2GR-FE 3.5L V6 found in the Exige 350 and Exige 380 variants.

Harrop has a wealth of experience supplying Supercharger Systems to OEM’s like Toyota, Ford and Lotus which has given us the experience and knowledge to offer the same level of quality and integration to aftermarket customers.

KINDIG IT ’55 MERCEDES GULLWING

In 2018, renowned car-builder David Kindig, of Kindig It Designs unveiled the extraordinary ’55 Mercedes 300SL Gullwing build at the SEMA Show in Las Vegas. To save a very rare and expensive vehicle from being modified, a fiberglass replica body was found and used as the basis of this ground up Restomod project. Hundreds of hours build time equates to unimaginable attention to detail, starting with the custom pearl exterior colour “Underslated” through to the meticulous bright red leather interior.

The engine bay also proves this is far from an ordinary Mercedes Gullwing with the factory straight six engine having been replaced with a GM LSX 454 (7.4-litre) crate motor cranking out over 477kW. Harrop was entrusted to provide the same level of quality and finish to the engine bay as the rest of the build, by supplying the Hurricane ITB Manifold. Undoubtedly the eye catching centerpiece of the engine bay, the Hurricane Manifold is fully functional and delivers the necessary air to power the 454 LSX engine via Drive By Wire ETC integration. The Hurricane Manifold suits the build perfectly, pitting old school attitude against new school engineering.

DETROIT SPEED SHOP ’69 TUX CAMARO

Undoubtedly the most awarded and meticulously modified ’69 Camaro ever built, this resto-mod project was 13 years in the making. Well known car builders Detroit Speed, were handed the challenge by owner Stuart Adams, to completely rebuild and modify the “Tux” Camaro to levels previously unseen in the industry. There is no doubt as to why it won the 2018 Triple Crown of Rodding award before heading to SEMA and taking out the 2018 Battle of The Builder’s title, which is the ultimate accolade.

As is the case with a lot of the top SEMA builders, Harrop was entrusted for hardware to enhance built LS2 engine with a highly customized orange finish HTV2300, featuring Eaton TVS technology to ensure maximum power and efficiency. The end result is an engine bay that is as functional as it is exceptional in detail and design.
