Marelli twin plug distributor for Porsche 911 RS RSR S ST

Description:
Raceservice4u Twin plug systems;

Twin plug systems were used on many flat 6 Porsche race engines.
Examples are 917, RSR 2.8 and 3.0, 914/6, 935 etc.

Experts recommend installing a twin-plug ignition system if the compression ratio is higher than 10:1.

911 engines need a high dome piston to get this high compression ratio.

The combustion chamber will then almost be split in 2.

It will take too long for the ignition flame front to propagate across the combustion chamber.

For a high performance engine you need a twin plug system.

Most Historic race regulations will not allow you to use contact less, a modern ignition system or a 964 dual distributor.

If you must use contact points; raceservice4u has the reasonably priced solution.
