Has anyone tried any of the MSD ignition products on their 3.0L Rangers or similar vehicles? Was wondering how much performance increase if any most people noticed.

Thanks,
Mike

 

Well I havent installed one as of yet,But I spoke with one fellow who likened the gains in power to that of Headers,Along with better response and mileage.It sounds really optimistic,but I think its worth a try....

 

Without other modifications you won't see any increase.

If any one after market bolt on, was so productive, one wonders why our rides didn't come from the factory with them already in place, seeing as how the manufactures are so hard up to show any kind of improvement in engine performance.

I like to see real world numbers or dyno data, or some tests done, under some controlled conditions, so I can judge what the product has to offer & under what conditions it's designed to offer up it's caim to fame & if it really does anything I can use, under the conditions which I drive.

Usually these products are long on brag, big on cost & don't offer up much, if any improvement, for the way most of us drive.

If these after market folks know something the auto engineers don't & their product will do such wonderful things for our engines, why don't they just show the PROOF to the manfacturer's????

It would then sell itself & they could easily make a large fortune selling them to the auto manufactures, by the MILLIONS, rather than spending large amounts of advertsing money, to sell them ONE at a time, by trying to convince us to buy the product!!!!!

So IMHO if these products were so great for the money, my Ranger would likely already have it installed!!!

 

You have it right with "for the money". The cost/benefit of many modifications is that there just isn't enough benefit to the cost. Consider... you have two parts you can use for a particular application... say, an exhaust tip. A chrome one. Shiny... ooh... okay.. Anyway, you have your regular one and then your chrome one. The chrome one costs maybe 75 cents more (just a random number, people...) than the regular one and the analysts decide it would not cause a substantial increase in the vehicle's popularity. Say the vehicle already sells 50,000 units per year. Is it worth spending an extra $37,500 if it's not going to result in any considerable profit gains? This can be applied to anything... even though something is a good idea, it's not always a smart business decision. Believe me, engineers know a lot... there are all kinds of experimental vehicles and studies going on all the time. But when it comes time to make a vehicle, you have more than one guy calling the shots and without monetary support for your proposals, you're really not going to get very far with an idea, even if it might save .04 mpg or add 2 hp. It's cheaper to let the consumer modify according to their particular taste, in these cases.

 

I saw an article in a mag yesterday about the "mileage/power inprovers", you know the whirl/packer thingeys. Basically they said the none tested helped mileage and in fact most cost mileage. They also pointed out that 99% of the fuel is burned in cars as they come from the factory and the just isn't much energy left to gain. You need to pack more air/fuel into the engine to get mush of a gains. Its like the msd ignitions, if you modify the engine and start having spark troubles then you may need a better system, but the stock one is fine for the engine as it comes from the factory and providing more spark energy will not help burn the fuel any better, remember 99%. Now it you raise the compression or put a blower or nitros on it you start to blow out the spark and higher combustion pressures require more spark energy to get things burning. But not on a stock motor.

-Popular Mechanics, I believe. Better spark will help, like admiralturbo & Dave said, in conjunction with other upgrades.

 

Ford's EDIS system is hard to improve on. Any aftermarket ignition system will be a waste of money!!
