Ignition timing is easily the single most important tuning adjustment on an internal combustion engine and yet the concept of ignition curves continues to be elusive for many enthusiasts. Yet all it ...

Ignition timing is typically split into three types. The first is initial timing—that is, the amount of spark lead that is set using a timing light (aimed at the harmonic balancer) with the engine at ...

"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...

According to NGK, adding 10 degrees of ignition timing at idle will raise the spark plug temperature anywhere from 180- to 210 degrees Fahrenheit. This means that adding just one degree of ignition ...

Welcome back for Part 2 of tune-up tips for your older Corvette. Last time we talked about tricks of the trade when setting points. This month we will talk about setting ignition timing. The most ...

underway before tdc is reached. This gives a maximum cylinder pressure (and work output). This ignition timingcondition is about 20 degrees of crank rotation before tdc, i.e. 20 degrees btdc. From, ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

For car enthusiasts and performance seekers, optimizing engine response is a thrilling endeavor. Ignition systems play a pivotal role in enhancing this aspect by delivering precise sparks that ignite ...
