914-4 2L race engine, 10.3:1 compression ratio and twin Weber's
Anyone have experience with the MSD systems on a Type IV? I'm thinking there may be benifits to having the higher spark voltages when compression ratio is relatively high. MSD claims plug gaps of .050 - .060" are possible, and that multiple sparks at lower RPM's improve throttle response. Thus, makes sense, but does anyone have real world experience that support these claims? |

At the risk of this sounding like a dumb question:
I figured, like has been said above, once the charge is ignited, how does another spark help??? Nobody has been able to explain that to me. It seems like using a lighter against a fire that is already lit. Another spark plug (with a lot more complication) or a multi-firing spark plug... Once it fired, how is another spark going to help anything??? Please help me understand this. I've asked this before, but have never heard a reasonable answer. It seems to me like an efficient combustion chamber would solve it. Redundant spark is just expensive complicated wasteful extraneous complication. (We are talking 914s, not the most exotic race cars) |
