Frequently Asked Questions

Why will I benefit from a conversion?

Your vehicle will have a more flexible engine with greatly increased power in the lower and midrange revs meaning less gear changes, improved low speed pickup, better acceleration and improved towing ability. Also, the thermal stresses in the cylinder head are reduced and due to increased oxygen levels, fuel burn is improved and economy increased.

Why don’t the vehicle manufacturers use larger intercoolers to increase power output?

Manufacturers know the extra power is there but they have to compromise many factors. They have to design the vehicle to suit the possibilities of model variations such as the inclusion of Air Conditioning and auto gearbox, also the engine tuning needs to suit the varying grades of fuel around the world.

Are there adjustments to make to the fuel pump?

Yes, the method depends on the type of system on your vehicle. We can optimise mechanical pumps with simple adjustments, or for vehicles fitted with an ECU, where possible we re-program the chip with a new “map” created by us to suit your specific vehicle

Will the modifications affect my fuel consumption?

Generally the economy will improve as the engine will be running far more efficiently but there are many variables including personal driving style. A worst case is that you will have extra power for the same economy.

Will fitting the intercooler in front of the radiator affect the cooling?

No, the intercooler core is a “coarse fin” design to allow air to pass easily through to the water radiator. We are assuming an efficient cooling system.

Will the extra power affect the drivetrain?

No, although driveability is vastly improved, the power is still well within the vehicles design limits; generally the drive-train is the same as used on petrol models with greater power output. Unless specifically asked, our conversions are aimed at sensible, safe gains, we do not rely on false claims to sell our products.

How accurate are the performance figures you quote?

The figures quoted are taken from actual tests on rolling road or on road performance meter. However, individual figures will vary per vehicle due to many factors including history of servicing and even daily changes in ambient temperature and pressure.

Should I inform my insurance company?

We have to advise you to, as with any modification and we find companies respond according to their understanding of the conversion. We are happy to provide a letter confirming professional installation.

Will the modifications affect any warranty?

As with insurance, we would suggest asking your dealer prior to installation, but generally there are few problems. We have designed our systems to need as little alterations as possible to the vehicle and in fact we supply many main dealers.
