What is the purpose behind upgrading your ignition system to a MSD Setup?

 

I'm kinda new to the High Performance area and was wondering what these were used for......

 

Thanks.

MSD and similar ignitions provide a hotter spark and/or a longer burning spark. There is nothing to be gained IMO with one of these systems on a new truck.

MSD (Multi Spark Discharge) I agree unless your really running a super modified setup in these trucks and racing it, there isn't a need for one unless you just plain want one and can afford the cost and if that is the case then :puke: Just don't really see the difference you will get on a stock engine. Just like changing out the spark plug wires to a highperformance set. Kind of like killing a knat with a 16lbs sledge hammer. IMO I'm sure others will disagree.

 

Now on the older vehicles like my 65 Impala SS with it's 396, the MSD 6AL made a world of difference. It started better, smoother idle and crisper throttle response. Not to mention I can control the rev limit now and not worry about blowing the engine. In an old big block with a stock rebuild you don't want to take it much farther than the 5k limit on the tach. :puke:

I think theirs put out 45,000 volts compared to stock 30,000 volts. With multiple spark, they will burn more complete. They can also be used with overgapped plugs to work even better. If you are looking for every bit of power, get it, but otherwise you won't see as much on a stock engine.

It is a waste of money on a stock engine.

 

Aftermarket ignitions also help by being more stable at higher rpms (5k+) than stock ignitions.

Looks like I will take your advice, and not put it on my truck. I will mention it to my nephew who has a 69 Camero that could benefit from it.........

 

Thanks for the great info.......

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
