is a msd setup worth it at this point?

[Moparbishi]

been thinking of going to a msd 6a setup and im wondering if it is worth it. im running pretty decent sized turbo 24+ psi with good flowing heads and etc etc. im just curious if it is worth getting a setup (not to expensive now a days) or just sticking with stock electronics. i already have the blaster 2 coil and i loved that. seemed to help high rpm break up but it could have been just a older coil that i replaced.

any opinions?

Yea, I'd say go for it. At 24 PSI of boost and fuel to match, a more powerful spark will be beneficial.

bump for a good question, I was thinking about the same.

I havn't gotten to this point in my project to really worry about it to much... But interested in a solid answer

seems like its a dance around issue. always has been.
noone really wants to try it.

ill be getting dyno tuned really really soon and i might just get it and do some base runs with and without it. maybe put some dyno proof into its a waste or its great

Make sure you are running some good wires first. The ignition system won't cost you HP unless you are missing. A good set of wires can be used both on the stock setup and an upgraded ignition.

There are some good wire options out there for us. Which wire is best is another can of worms though.

It all comes down to basic electricity. On a properly running engine the average is 10 - 15 KV with a max of 25 kv(under load) to jump the gap at the plugs and start combustion. Electricity is very lazy and you will not produce any more voltage than is necessary to jump the gap regardless of your ignition systems potential.
The stock coil is capable of 40KV but if conditions in the combustion chamber change from mods such as increased compression or boost the stock coil may not have a long enough durtion period at high rpm/high load conditions to produce a spark strong enough for complete and proper combustion resulting in high rpm misfire. This is where a performance coil will help. Understand that electricity being lazy will always look for the easiest path to ground and if that ground is not the spark plug it will go elsewhere if it is available so the rest of your secondary ignition must be in top shape. 7mm wires are not designed to handle that type of voltage on a constant basis such as in a true race application. If the current can escape thru faulty insulation to ground it will. Also a distributor cap and rotor with copper terminals will help lower the resistance in the circuit.
If you have access to an ocilloscope look at parade pattern at idle and then snap the throttle quickly which will show the systems requirements under load. To see your max coil output disconnect an ignition wire and you will see KV spike to max.
Again this is just electrical classroom fact and alot of times adding performance replacement parts such as coils, wires, plugs makes you feel better and it seems as though the vehicle is running better and the mental aspect of driving makes it more enjoyable.
I used to spend a few hours every weekend cleaning the car and after I was done the car always felt new again and was a pleasure to drive.
So... do what makes you feel good.

At some car shows, you will find an MSD ignition vendor and they do demonstrations of how much more powerful their systems are. I tell you what--after comparing the GM HEI ignition vs the MSD, it is obvious which is the more powerful spark.

My wires are MSD
