So what exactly is engine knock and how dangerous is it? What causes engine knock and how can it be avoided?
You may notice a knocking or rattling noise from your engine or a sudden loss of power under full throttle.
Immediately back off the throttle and only use low rpm engine speeds until you can get the engine investigated.
The chances are that you are suffering from a condition known as “engine knock”.
Quick shift gearstick quickshift kits
Being able to change gear as quickly as possible can make a big difference in time critical situations like drag racing and even track day racing.
The slowest component in any car is the driver and there is little that can be done to improve that. A quick shift kit will help to give you the competitive edge by enabling faster gear changes and allowing more ‘feel’ by reducing play.
Boost controllers and remaps
Boost controllers
The turbo is driven by the exhaust gases and the faster the exhaust flows the quicker the turbo spins and more air gets forced in to the engine.
If too much air is forced into the engine then it will run lean. This causes an intermittent loss of power and you also risk putting too much pressure on the engine with a surge of power.
How to lower the engines compression ratio
Reducing the compression ratio is required if you want to run a high boost supercharged engine. High compression NA (naturally aspirated) engines are quite efficient but when adding forced induction you want to lower the compression ratio.
The compression ratio has a dramatic effect on an engines performance and the problem of knock, (where the air fuel mix prematurely ignites) is controlled to a large degree by the compression ratio.
