Apr 16, 2015 · On a street car, a vacuum-advance and a centrifugal-advance system are used. The vacuum advance increases timing as the vacuum created by the engine increases (idle and low-load conditions). As engine load or throttle position increases, the vacuum decreases, and so does vacuum advance timing. Sep 04, 2015 · But for street engines, a curve is generally used to improve drivability and throttle response. Plus, a fixed ignition advance of 36 degrees in an engine with high compression will make the engine difficult to start when hot.

When setting the timing for an automobile engine, the factory timing setting can usually be found on a sticker in the engine bay. The ignition timing is also dependent on the load of the engine with more load (larger throttle opening and therefore air:fuel ratio) requiring less advance (the mixture burns faster). timing curve when used with 12° initial timing set at engine idle. This, however, is not perfect or optimum for any one combination. A street/strip car that runs on pump gas may “ping” with this much spark advance and will require less initial advance or heavier springs to slow down the “curve.” Where as a low compression, low stall speed Ignition Timing for Modified Engines An often neglected but important area when tuning an engine is the ignition system.
