[edit] Other Applications section

Does anyone else here think this section is unnecessary? The idea of using 2 spark plugs per cylinder, dates back before the Alfa Twin Cam racing engines of the 1960's to earlier racing engines and aircraft engines. Should we add every twin spark plug aircraft engine [1][2][3] to this section of the page, or should this page only cover Alfa Romeo twin spark engines? --Xagent86 (Talk | contribs) 12:19, 17 February 2007 (UTC)

I think there should be different page to twin spark technology? and keep this page only for Alfa engine Typ932 08:26, 14 March 2007 (UTC)

Did the other twin spark engines fire the plugs asynchronously? PiP 22:57, 25 April 2007 (UTC)

 Dear sir
In the early 1970s i made a device to enable a single spark plug to fire more than once on the 

same firing stroke by using a simple multi-vibrator system and i conected it up to my old 64 Vauxhall Victor and it worked a treat but it meant it had to fire when the points were closed instead of the conventional method (ie)when the points are open ) it improved the power and the fuel consumpsion so i went across the road to a firm called SGS Fairchild in Falkirk and i spoke to a gent about my idear and that was the last time i ever heard anything about it but a few years later the Alfa car company brought out the twin spark ign system

I call BS on that ^^^. 1. Firing the spark plug where the fuel air mix has already burned is not the best idea in the world. 2. If you can show me a way of getting mega voltage out of an inductor when you're building up a field instead of collapsing it... PiP 04:33, 8 July 2007 (UTC)

[edit] Other Applications

The 4 cylinder T series Toyota engine utilized Alfa Romeo's Twin spark design for its World Rally Championship engine, the 4t-gte. It was also applied in the consumer version of that engine, the 3t-gte, and is a relatively sought after design in semi-classic Toyota tuning circles.

The 1.9 litre 6 cylinder inline Porsche engine set in the racing-only 911R (of which twenty were produced) utilized the twin spark design in a souped up engine from the 911T. Production ran from 1967 to 1969 and the change to twin spark helped boost the engine's output from 130hp to 210.
