240ℓ/h Or Higher (Fuel Pressure 3kg/㎠)
Recommended: TOMEI 255ℓ/h (Fuel Pressure 3kg/㎠)
To work out the fuel pump size you need you use this formula,
Injectors Capacity x No. of Cylinders x 0.06 = Fuel Pump flow rate required.
Then consider that the fuel pump should be used at 80~90% capacity when making your choice.
Choose the right high flow air filter to suit your power target.
When running at higher boost, the stock suction pipe is not strong enough, so deformation occurs.
You can improve the intake efficiency by upgrading it. However, when taking advantage of the
straight airflow method, idling will become rougher and it will be easier to stall the engine.
Pressurized air from the Turbine is compressed and sent to the engine. This process forces the air
temperature to increase with heat. So when it does, the air density drops and combustion efficiency
becomes poor, resulting to performance loss. The intercoolers job is then to extract the heat from
the forced air via the fins in the intercooler. This again helps compress the air again, and the
denser colder air will improve combustion efficiency to optimize performance.
The Hyundai Genesis stock intercooler is too small, so when you start to tune the engine, you'll
have to pay attention to the intake temperature conditions when using the stock intercooler.
When the throttle is suddenly closed, the forced air from the Turbine will have no where to go.

When the throttle is suddenly closed, the forced air from the Turbine will have no where to go.
This restricted flow places a heavy burden on the turbo and other parts. So the Blow Off Valve is
fitted somewhere between the turbo and the throttle to prevent this problem by giving an option of
an escape route to vent the excess pressure. This saves the turbo from any possible problems. The
stock BOV was never designed to handle high boost applications, so it will struggle to do it's job
properly when the limits are exceeded. This puts the turbo at risk of failure and response drops.
This is why we recommend to upgrade the BOV to a stronger type.
Additionally, when the BOV is a vent to atmosphere type, this can cause other problems with the
flowing into the engine. ECU not being able to read correct air volume that is flowing through it.
As the volume of air still passes through the air flow meter but not all of if goes to the engine. In
this case the air to fuel mixture will be incorrect. So we recommend the recirculation type design.
By upgrading your camshafts, you can increase the exhaust pressure, this in turn will help
spool larger turbines efficiently once the exhaust manifold has also been changed. All together
will aid with the performance increase. Then your larger Turbine will be able to come on boost
faster.
The stock outlet pipes will hinder the gas flow efficiency. At higher engine speeds (RPM), these
narrower outlet pipes will choke the Turbine exhaust gas flow, causing the boost to be unstable.
With the larger outlet pipe, exhaust gas flow will be more efficient, boost will stabilize and the
efficiency of the Turbo will increase.
By using a similar sized pipe with the outlet pipe diameter, exhaust gas flow will be smoother,
better mid range pick-up and more power in higher RPM range.
