Improved throttle response, drove a 20V with msd sci. Car was bone stock except for MSD, no power difference but throttle response was excellent, if you have the cash to spare, get it but the money can be spent on other essential mods.

well i dont know where you guys get your info from??
if you want a good ignition for street use then i'd reccomend a 6AL or even just a 6A only difference being a rev limiter in the 6AL

the MSD 6 series ignitions feature a capacitive discharge ignition design. The majority of stock ignition systems are inductive ignitions.
in an inductive igntion, the coil must store and step up the voltage to maximum strength in between each firing. At high rpm, since there is less time to charge the coil to full capacity, the voltage falls short of reaching maximum energy which results in a loss of top end miss.
the MSD ignition features a capacitor which is quickly charged (within one millisecond) with 460-480 volts and stores it untill the ignition is triggered. with the CD design, the voltage sent to the coil is always at full power at high RPM.
the MSD 6 series produces full power multiple sparks for each firing of a plug. the number of multiple sparks that occur decreases as RPM increases, however the spark series always lasts for 20 degrees of crank rotation. Above 3000RPM there is simply not enough "time" to fire the spark plug more than once, so there is only one powerful spark.
as for the limter models.
6AL, 6ALN, 6BTM: these ignitons are equipped with built in adjustable soft touch rev controls. MSD rev limiters are adjustable with plug-in modules which are available in 100RPM increments. The soft touch circuitry provides a smooth and accurate rev limt by dropping the spark to individual cylinders. The soft touch produces a load-free rev limit that is withen 1% of the selected RPM.

so for a street driven stock engined car i would reccomend it there not to expensive either, it will still make it more responsive, more efficent (better spark= better burning of the fuel).
i noticed a difference in mine from stock ignition to the MSD i run it wasn't faster up top but was more responsive.

Any aftermarket igntion is only going to be of benefit if the stock system is failing due to spark scatter or breakdown of some sort. We've proven this many times on the dyno. I can even put in anew set of steel spark plugs to replace a set of platinums etc & a new set of plugs regardless of type providing tthey are close with regards to gap/heat range will generally show up a 2hp gain for about one dyno run maye two. We've got 700hp skylines running round on the stock ignitions, 500hps wrx's same thing we do heaps of 250hp+ non-turbo hondas all on the stock ignition. What do we do when we have a ignition problem, go back to stock for starters & work from there. The only real ignitions that give gains are the likes of the top end crane/msd/link ignition units which are laptop programmable so you can adjust the advance curve etc to suit what you need. Before you go out & spend money on an MSd etc that you probably don't need unless your running heaps of boost or some damn big cams with heaps of compression there is a few things you can do to make your ignition work better & a fair bit of it comes down to spark plugs & there is a few tricks here which can brings reasonable power gains, but that's a performance secret that i ain't gonna give out.

So can anyone give me a breif idea of installation of an MSD system?
Like do you have to wire anything up to the distributor? Does it replace the coil pack? Is it an aditional thing to go in with the coil pack?

I notice on my coilpack (3SGE), theres 2 plugs. One has 5 connections in it, the other two. If I unplug either of them, engine won't start.

I'm getting mighty confused about how these things are implimented into a car!
Motorsport is like sex. You could take it to track and have a long, enjoyable session, or you could take it to the strip and get it over with in less than 20 seconds.
