Improving performance using walnuts
Walnut blasting involves cleaning the intake manifold and valves of a car’s engine through high pressure blasting of finely crushed walnut shells. A biodegradable abrasive, walnut shells assist in clearing carbon build up in direct injection car engines.
Carbon build up interferes with the car’s normal airflow, altering the compression ratio, operating temperature and overall efficiency. Walnut blasting effectively removes stubborn carbon deposits from an engine’s intake valves, restoring original function thus improving performance and fuel efficiency.
Our walnut blasting service
Walnut blasting can be carried out without removing the head of the engine. We simply remove the inlet manifold and any other parts that may prevent us from accessing the inlet ports. We check the valves are closed, if not we rotate the crank clockwise until they are.
Ensuring we have enough compressed air pressurised, the 3D printed engine/port specific attachment is slotted into the walnut blaster's vacuum, switch it on and insert the nozzle that shoots walnut shells through a small hole in the 3D printed attachment and pull the trigger, releasing the crushed walnut shells into the intake port.
Carbon deposits are released from the surfaces and are sucked into the vacuum, along with the crushed walnut shells, leaving the ports looking like new.
Before & After Walnut Blasting
An environmentally friendly alternative
Walnut blasting is an environmentally friendly technique of cleaning your car’s engine when compared to chemical-based methods. Walnut shells, a biodegradable product, aid in minimising environmental impact by reducing waste and avoiding the use of harsh chemicals.
