Msd Ignition Module Placement - Opinions

Interesting, do you have any pictures of the installation? So, it is inside the IPD housing below the filter?

Thanks,

Stan

Yes it is inside but flat on the bottom, kind of diagonal orientation overall with small side of 6a ~parallel to the MAF side of the aluminun box...I don't have a pic of that, at least not on my work computer or phone...wifey driving it so I can't shoot one real quick, sorry.

I had the 6a in the airbox for a long time, no issues. However, not a fan of the 6a for our cars. Caused ignition issues and helped eat through plugs every 6 months. Stock ignition is fine for the 850 for our needs in my experience. Any minimal gains were not worth the other troubles.

Agreed. I'm not sure it is totally necessary either. Justus is running a fairly large gap (I thought .030) on the 60 trim and has no issues with blow out at all.

I think it may be causing me some cold start idling issues.

.030 Gap with Stock R plugs, Kingsborne 8mm wires, Bosch cap and rotor.

Without changing plugs or cap/rotor I saw an immediate difference in the way my car ran after I installed my blaster coil and 6AL. Seems to pull a bit smoother in higher rpm range.

If you get the chance to compare: pull the coil wire on the stock ignition setup and pull the coil wire on the MSD setup and hold the wire about an inch away so it arcs. The spark is visibly and audibly stronger.

What he said.

Noticed a difference right away and a couple days later when I swapped the plugs I was able to open the gap up to around .030 where I was limited to .025-.026 before.

Only drawback I've found is it definitely eats plugs/caps/rotors faster.

That's what my head told me as well.

Performance and maintenance wise my plugs ran hot and expired faster, and I had all sorts of ignition issues.

If someone wanted to do a review and show how the gap difference actually corresponded to performance with our cars, I would be like to see it.

If you had 'all sorts or ignition issues' perhaps something else was up.

Wider gap = better spark - just doesn't work when the stock system can't support the spark at higher boost levels. The MSD6a fixes that at the expense of shorter cap/rotor/plug life

Maybe, but many have had the stock ignition system do just fine at higher hp levels then either you or me are running.

Never seen any real data to show how any MSD components have been improvements over our stock ignition systems.

It can "feel", "sound", and "appear", but that's all I ever got from it.

No need to patronize.

I pretty much agree, my butt said YES!

And no doubt a hotter spark *should* equal more power. I'm just not sure what benefit I'm realllly seeing with it.

Would be nice to dyno with and with out it on the same day and see what happens.

Are you guys all running the analog box or is someone running the newer digital box (besides me). I have not experienced the issues mentioned in this thread or any negatives for that matter. Granted I don't dog the car, but when I summon the power, it comes. I have 30k on current plug/wire/rotor&cap, and keep waiting for misfire or other bad stuff...nothing...

I think Lee is running a digital box. I am running the analog. I don't have any issues under boost, what-so-ever.

I can't honestly say my problems stem from the 6A until I swap to my other coil/power stage. I also can't say I picked up any notable power either. For me it's neither here nor there. I will swap out to the other coil and see what happens.

I'm only talking about the spark amplifier - the MSD6A. The coil is a waste of money, it's not going to perform better than a healthy Bosch unit.

Maybe there are folks who can afford to dyno before/after comparisons of individual components, I'm not one of them. All I can say is that I was able to run higher boost with a colder plug & wider gap using the MSD6a than with the stock setup.

I know there are those making more power with all stock (ign) components, I can't speak to that. The ones I'm aware of are not in the US, so perhaps fuel quality is also a component there.

Yes, I'm running the digial 6A and no issues yet. But then again, I don't think the 6A even has a 1,000 miles on it yet.
