Frequently Asked Questions

This Frequently Asked Questions list has a list of the most common enquiries faced by GasResearch along with common answers and solutions.
You will save a lot of time by reading through this list before contacting GasResearch with your enquiry, chances are, we have already answered your question.

Why is the GasResearch system different?

The GasResearch Throttle Body utilises a unique LPG metering system to ensure that your engine is always running with an optimal fuel mixture.  See the Products page for more details on the GasResearch range.

I run a dual fuel carby system now, why should I go straight gas?

There are numerous benefits to running straight gas, the main ones being:

     -     Less restriction to air flow = better power/economy

With your current setup, i.e. tophat or snorkel on top standard pertol carby, the air must pass through the gas mixer and then the petrol carby, this means the air is restricted twice regardless of which fuel you run.  Running a single carb with our specially designed diffuser system significantly reduces restriction to the engine.

     -     Dedicated tune

When running two different fuels with different octane ratings, you must tune the engine to be able to run without detonation on either.   This means that you are always seeing a compromise between the correct tune for each fuel.   When running straight gas, you can alter your ignition timing to suit the higher octane fuel, and hence improve power and efficiency.   There are a number of other things you can do to improve performance when running straight gas, for more info see our Engine Preparation Guide.

     -     Better Fuel Control

This advantage applies only to the GasResearch unique lpg metering system. The GasResearch throttle bodies allow the vehicle to be tuned more accurately, meaning that the engine will always recieve the correct amount of gas, thus ensuring excellent fuel ratio control and therefore better engine efficiency, leading to improved power and economy (when compared to traditional gas systems).

Can I fit GasResearch to my car?

GasResearch systems are suitable for most any naturally aspirated (and some forced induction) vehicles.  Kits are available for the more popular Australian vehicles as can be found on our Prices page.  If your vehicle is not listed, GasResearch recommended installers (see Fitters) will be able to adapt GasResearch components to suit your application.

What about forced induction?

GasResearch systems are suitable for some forced induction setups, if used in a draw-through configuration.  GasResearch does not recommend it's systems be used in blow-through set-ups.  In either case, we highly recommend having your forced induction system installed, set up and tuned by professionals, see our Fitters list for reputable installers.
Refer to our Technical Support section for more details on forced induction.

Blow-Through and Draw-Through, what is the difference?

Blow-Through systems place the throttle body or carburettor between the turbo/supercharger and the engine.  This means that the throttle body is under pressure, which can potentially cause problems with GasResearch systems (see Technical Section for more information).
This configuration allows the use of aftercooling devices and may require the use of a blow-off or boost relief valve (available as a GasResearch performance part).
Draw-Through set-ups require the throttle body or carby to be placed at the inlet to the turbo/supercharger.  This means that the 'charger and all further induction pipework to the engine contains the compressed air/fuel mixture, this can cause problems if backfires are encountered.  As such, inlet ducting should be kept as short as possible, and intercoolers and blow-off valves should not be used.

I'm rebuilding / having an engine built, what can I do to make it run better on LPG?

There are many things you can do to optimise your engine to run on gas, for guidelines refer to our Engine Preparation Guide.
