The Rotrex centrifugal supercharger delivers boost with increasing engine speed (rpm), rather than immediately from low engine speeds. The advantage of this is that it reduces the need for transmission upgrades – a large increase in torque at low engine speeds is typically what breaks transmissions (gearboxes, clutches, drive-shafts, differentials). So the fact that the centrifugal supercharger delivers the boost at higher engine speeds is an advantage in this respect.
We will supply whichever Rotrex supercharger best suits your performance requirements, existing engine specification and application.
We include many features as standard that others regard as ‘an optional extra’ which is usually added on afterwards – including an intercooler, uprated fuel injectors, uprated crankcase ventilation system, K&N air filter, all required mapping & power runs, etc.
Please note that your vehicle will require a fully programmable engine management system with full 3D control over the fuel and ignition systems (e.g.: Canems, Emerald, DTA, MBE, Megasquirt, etc). We are able map most fully programmable engine management systems to suit this forced induction conversion. We will not carry out a forced induction conversion on a Rover V8 that is still using a distributor, a non-programmable ECU or carburettors – it is possible to run forced induction on these set-ups but we do not think it is worth the risk to the health of your engine.
Please also note that if your engine or transmission is not in a good state of health then this forced induction conversion is likely to find the failure point of any pre-existing issues. We always carry out some engine health checks prior to starting the conversion (e.g.: compression tests, block test, etc) and will also carry out a basic ramp inspection of the transmission, suspension, brakes and tyres. We cannot be held responsible for any pre-existing issues but will advise if we see any issues prior to carrying out the conversion.
We are now able to offer this conversion for pre-serpentine Rover V8 engines too. There is however an additional charge of £600 plus VAT for a custom front crank pulley.
