AT the request of Augi, I have joined this thread to provide some insight into the DirectHits technology and answer questions about applications.
First, DirectHits is a pulsepower derived technology that utilizes a capacitor to store energy during the beginning of the ignition event and discharge the energy very quickly once the resistance spark gap has been overcome and a spark channel generated. This process increases the peak power of the spark and reduces cycle-to-cycle variations in combustion pressure which is the result of poor ignition.
A good analogy, is the AA battery. In a flashlight you get a beam of light, but put the battery in a flash camera...that's the difference
One thing you need to stay aware of..the small engines you are using are generally ignition challenged. They do not have a lot of energy and when using DirectHits with them you generally need to set a smaller than stock gap.
Torque is probably the most noticeable benefit you will extract based on your applications and all applications will take the DirectHits S80 product.
You must use a non-resistor spark plug with an insulator 1" long and capped with a threaded post. This is what the DirectHit attaches to.
If I can answer any questions please feel free to respond
