What is Engine Detonation? · Help Center - Summit Racing
Because detonation interrupts that design, it robs the engine of power. Most engines can handle some minor detonation. Modern, fuel injected engines can sense a knock and adjust the …
What is Engine Pre-Ignition? · Help Center - Summit Racing
It is similar to Detonation, but it is different. When pre-ignition happens, something ignites the Air/Fuel Mixture d uring the Compression Stroke. This creates too much pressure inside the …
Supercharging Basics – Engine Preparation · Help Center
Detonation is the single most destructive force in a supercharged engine. This may include lowering boost level, retarding timing, installing a boost timing master, increasing fuel flow to …
What is engine quench? · Help Center - Summit Racing
The right amount of quench can promote fast, complete burn of the air/fuel mixture. It creates turbulence, which forces the air/fuel mixture toward the spark plug. This reduces the possibility …
What does the gasoline octane rating mean? · Help Center
Use the octane recommended by the engine manufacturer. Running gas with a lower octane rating will cause a reduction in power and fuel efficiency and possibly engine damage. This is …
What is ignition timing? · Help Center - Summit Racing
Retarding the timing means the plug fires later in the compression stroke (closer to TDC). Retarding the timing can help reduce Detonation. However, if the spark happens too late, you …
What are the differnt Piston Styles? · Help Center - Summit Racing
It can be used in turbocharged or supercharged engines to help avoid Detonation. It makes for a fast-burning, compact combustion chamber. Domed Pistons. This piston has a dome-shaped …
What is the compression ratio? · Help Center - Summit Racing
High compression engines require fuel with a higher Octane Rating to prevent Detonation. Engines with power adders will require a lower CR. Camshaft selection and Ignition Timing …
Do I need aluminum heads? · Help Center - Summit Racing
Aluminum heads will dissipate heat faster. This allows for higher Compression Ratios with less risk of Detonation. The cooler head also delivers a cooler air/fuel mixture to the combustion …
How is Electronic Fuel Injection (EFI) Controlled? · Help Center
Knock sensors are located on the engine block. They are very sensitive and detect Detonation as soon as it happens. It signals the ECU to retard timing. Idle Air Control (IAC) Valve/Actuator. …
