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
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
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
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.
