Above: Company demonstrator uses the BMW V12 400bhp

From 1999 Parallel Designs fitted the Rover V8 ( including the tunned TVR plants )in various capacities to our vehicles,

In 2004 we designed the chassis to accomodate the 5 litre BMW V12 with 300bhp standard,

Our next company demonstrator will have a tunned 5 litre BMW producing just under 400bhp. Using the BMW V12 as a test engine has enabled us to assess the chassis fully and we are confident that it can happily take more power than we have used to date. Our Orange Diablo GTR Demonstrator uses a 420 bhp 5.2 litre TVR Griffith unit from TVR POWER for there Race Touring cars, and has proven to be perfectly acceptable for the current chassis and so we are hoping that a V12 unit at around 500bhp will be the next stepping stone.

The Torero project has been one of continuing research and design and rest assured that any engine configuration will be fully tested before being marketed as an option.

we can supply any version of the Rover V8 engine, from 3.5 carburettor to 5.2 injection,also from BMW V12 5.0 to 5.7. In addition, we can offer the engines in various states of build, from 'short block' (meaning just crank/pistons/rods/camshaft/oil pump) to 'turnkey' which literally means the whole assembly complete with alternator, starter, air con pump, fuel and ignition system with wiring loom. An engine supplied as 'turnkey' specification only requires a power and fuel feed to run.

COOLING SYSTEM

The Torero cooling system is extensive. Many Lamborghini replicas have suffered from cooling problems in the past due to various reasons. Primarily it was not being able to understand just how much heat was produced by the Rover V8 in a confined, rear mounted environment. Add to this a poorly designed coolant sytem (often taken from 'donor' cars) with inferior radiators and in-efficient routing and you will eventually come accross severe overheating problems, especially on a hot day. With that in mind, we decided to go all-out on the development of our system which involved starting from scratch. Every part outside of the engine has been designed and built by us to maintain a safe temperature, no matter what situation the car is in. This includes being sat at idle for hours on end with ambients of more than 30 degrees celcius. Our radiators are brass in construction due to the superior thermal efficiency and each uses it's own thermal fan switch and fan. Water is taken into and out of the engine via our aluminium cooling pipe kit which uses 4-ply silicone joiners for reliabilty. In general running, the set-up is so efficient that it is rare to see even one fan switched on. In extreme circumstances both will switch but we have yet to see water tempertures become excessive, even when used with our current 5.2 litre race-tuned unit.

In addition to the comprehensive cooling system we have also equipped every Torero with a 13-row oil cooler. Again, the rear mounted layout of the engine can give rise to overly high oil temperatures if used hard without a cooler and thus our kit keeps this unwanted risk in check.
