Performance Exhausts

Why does it Work so well in Turbo Diesel:

The Law of Adiabatics – as a gas cools it expands, as the exhaust gases move away from combustion they are expanding at the greatest rate, as they are cooling at the greatest rate. The turbine spins earlier due to the greater space for the hot exhaust gases to expand into.

It’s the expansion of the gases that make the turbo spin, as they rush past the turbine into the greater space of the larger exhaust.
The earlier spinning leads to earlier boost pressure which leads to improved efficiency, hence improved economy and lower down torque.

Taipan Exhaust, King Brown, Advance, Pacemaker are all brands supplied and/or fitted by GO 4×4. The kits come with dump pipe, flex joint, hi-flow mandrel bends, mount to the original mounting points with a choice of muffler, straight through pipe or hotdog*.

They can be as quiet as the factory system or as noisy as a drag car. Please note, more noise doesn’t equate to greater flow.

The reason? Remember, diesel fuel detonates due to the compression of the air-fuel mixture on the compression stroke, it is the compression that lifts the temperature to ignition. If there is not enough ‘back pressure’, the upper cylinder temperatures reduce to the point where more compression energy is required to cause combustion. More energy is used from the other ‘firing’ cylinders to force the piston higher, hence energy is being absorbed, power output is reduced. Timing is also altered, reducing power output further.

For more low down torque for 4WDing, better towing and safer overtaking on-road, with improved economy, the hi-flow exhaust will make a noticeable difference, up to 15%. For more significant gains, refer to Custom ECU Re-mapping.
