What is Engine Detonation? · Help Center - Summit Racing
What is Engine Detonation? Detonation is spontaneous combustion inside the cylinder AFTER the spark plug fires. It is similar to Pre-Ignition, but it is different. During normal ignition, the spark …
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 …
What is engine quench? · Help Center
It creates turbulence, which forces the air/fuel mixture toward the spark plug. This reduces the possibility of Detonation. It also leads to cleaner emissions. What should it be? Quench should …
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 are the differnt Piston Styles? · Help Center
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 does the gasoline octane rating mean? · Help Center
This is because the ignition timing will need to be retarded to prevent Detonation. On the other hand, a higher octane rating will not improve the engine's performance. The Compression …
What is ignition timing? · Help Center
Retarding the timing can help reduce Detonation. However, if the spark happens too late, you will lose power. This is because the cylinder pressure won't reach it's max until the piston is …
What is the compression ratio? · Help Center
Definition and Description Compression Ratio (CR) tells you the relationship between minimum and maximum cylinder volume. The cylinder is largest when the piston is at BDC. It is smallest …
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
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 The IAC is located on the throttle body. It is …
