I've heard that MSD Ignitions will increase performance, true?
Does anyone have MSD or other brand, can you tell me about it? Thanks.

 

been looking at msd aswell, my friend has it in his rx7. plus always fire right and increased acceleration a bit.

 

cool - so i guess it's worth it. I dont understand all the secrets behind it though

 

on a slightly modified street car its not worth it IMO. you'll only see minimal gains and maybe some midly improved MPG.

 

I might look into getting one. If it will enhance anything at all

 

Heh... I have 8.5mm MSD Ignition wires and a Blaster SS coil. When I get my 6A box im going to put it all in and let you guys know how it goes.

 

any news????

 

I for one have absolutely no experience with MSD, or any of their products.....

Ok heres the info on an MSD Ignition setup....

My Mustang has a Billet Distributor, Blaster 2 Coil, and 6A control box. An MSD box changes your Ignition to a capacitive discharge style (I cant remember the other style). The Box itself does a number of things, its basic function is to tell the coil when to fire. When doing this however, its signal to the coil has alot more power in it, and it can spark much faster and accurate than any other system. This is achieved by using capacitors in the Ignition Control box. Now the second thing an MSD Control box does is it sends out Multiple Sparks per cylinder. A car from the factory will fire once per cylinder, while the MSD will generally fire atleast 3 or 4 times during the combustion stroke. This creates a cleaner more powerful burn which results in more power, which means better fuel economy, and lastly lower emissions.

You can generally use an MSD control box on a stock setup. Its one of those modifications which gets better with more mods, like boost or nitrous.

The 6A box is your basic control box, while the 6AL has a rev limiter built in which you can set.

If you have any install questions let me know, but its only 7 wires to hook up plus one wire to roll up and insulate, or wire to a switch for a ignition kill switch.

the only thing I would add to this is that the MSD only fires multiple spark at low rpm. Once it reaches a certain rpm it is a single fire. I used a Mallory in my race car because it was a hotter spark than the MSD and was a lot easier to change the high and low rpm limiter with switches instead of pills. Still have the box and my good dist.

 

3300rpm and the multiple sparks cut out I believe.

granted the higher end MSD boxes have alot more adjustments, but I believe the Mallory's are around the same cost as the 6A and 6AL.

The Mallory is called a Hy-Fire isnt it?

MrGone

 

Yup I hace a Hy-Fire IV C, a Mallory Comp 9000 magnetic dist., and a Mallory Promaster coil. I liked the setup a lot on my Chevy II. It hasnt been on anything for about 5 years now though.

I really only chose the Mallory over the MSD stuff because of the adjustability of the hy fire box and for the money it came with a low (staging) and high rev limiter and I needed both. I think that MSD is a little better quality maybe but I never had a problem with my Mallory stuff and as soon as I put together my Chevelle the stuff is going in there.

 

wow, Soul Fly lives!

Well an MSD Pro-Billet distributor (68 stang) is a lil different than just the ignition no? I've seen it on one 3rd gen. It was at Nopi Nats last year....

Although it's not IN the pic....its on the left side firewall.

 

I said nothing about Pro-Billet, just billet

All you need is the Control Box, and might want to get the Coil, you do not need the Dizzy, unless you want to be crazy fast like me (that is a joke )

 

how much is a 6A box?

 

now you know all my dirty little secrets.

MrGone

 

Not too bad. Can be done on a max? And I have to buy the distributor and the ignition coil to go along with the box, right?

Thanks for the info, I know it's tough giving up your dirty little secrets.

 

no it will work with your existing dist. and I THINK coil (cant remember because its been a while) but it would be recomended to upgrade the coil.

 

thanks for the info, msd takes orders online, right?

 

You can use your stock coil with the MSD, with out a problem, its just that if you get the MSD Coil you will beable to have optimum performance.

You do not need the Distributor, I bought mine simply because the one that came on the mustang was worn out and I could not get it run correctly (below 1000rpm) the dwell would constantly change because of the play in the shaft and such. awsm66 may have bought his for the same reason, or just because he needed a higher performance, tuneable one for his application (race car).


MSD's website, www.msdignition.com does not accept online orders, however www.summitracing.com does, and have pretty good prices. Shop around for a deal, either on other the forsale sections of various forums, or ebay.

I'm planning to do the MSD6AL and Blaster 2 set up on my '91. Where could I get the wiring diagram. I couldn't find it on the MSD website.

Thanks

 

I've got it in a ignition modification book from barnes and noble and it's in there, as well as any MSD coil you purchase normally has a schematic with it. I gone with the Mallory 6 ignition box and oil filled coil, for My setup, even found a plug to use as plug-n-play with the engine harness! More than likely my ignition box/coil will be setting on the frame near the p/s reservoir. Oh yeah, don't worry it's only about 5 or 6 wires and it's pretty easy to install....even for a 12 yr old!
