Had another car towed in today....MSD 6A burned up the cap and rotor (sheeesh, why do people keep using this crap?)

No start, checked everything in the system and then pulled the cap off only to find the burnt components. Replaced the rotor and wella she fired right up (albeit the cap looked like junk).

 

I have been in the same arguement with people on these boards about the uselessness of an MSD6A on these cars. Its basically redondant with the factory eletronic ignition. Fix the factory componants and there is no need for one. Anyone that claims a gain from them has faulty factory componants to begin with and they are just temporarly masking the problem.

*I run a good ol A/C Delco ignition module
*Hypertech 53,000 volt coil with heat sheilding under it (stock is 38,000, MSD Blaster is 48,000)
*Accel cap and rotor
*Taylor 10.4mm racewires
*Taylor firesleeves to protect the boots
*Standard Autolite plugs (not the platinum crap- our ignitions are too hot for them and burn them up. They are designed for the latemodel multi coil systems that are lower voltage.)

All these parts are workhorses and are the best against heat.

 

Oh yeah Don, I almost forgot....




I set that ignition timing with my trusty Spohn timing light

It "handles" the job

(ps- It finally gave me something to do with that sticker- I just ran out and did that just to bother you.)

 

Agreed 100%

I have no arguement with Spohn's parts they're cheap......he for sure know's what they're worth.....but I wouldn't say that to bother you

 

All reality with all that wrong.. Someone did not maintance? How old is this stuff?

Let's bring some New Electronics to the table.. And see where were at.. Msd has it's issue's but.. Purpose is.. Maintance..

 

The word is "voila". Look it up.

My MSD box still works fine but the MSD coil took a dump.

 

Read Dean's post again and forget about "new stuff" when you already have the best there is for our cars you don't need anything else.

But then.......you know what they say "if it feels good do it" ( just be ready to except what comes with it).

 

my MSD box caused my car to crap out on me in the middle of the 19 fwy.. couldnt even get the car to hold idle.. unplugged the MSD for fun.. VRRRRROOOOMMMMM

piece of crap..

 

I got rid of the 6AL when I had a nightmare of a time just to get the sucker hooked up on my IROC. My 91 Z I just bought came with a 6A under the hood and I have been thinking of just pulling it off and selling it

 

I haven't had a problem with 6a MSD. Had it for 5 years. I guess using a Blaster 3 coil makes a difference.

 

Who are you kidding...you have had all kinds of problems....you just haven't been able to pin it on the MSD ....YET!
LOL

 

Well I think we are occurring all kinds of new problems.. Do to modifications.. But if the boxes are working for certain people.. We know the deal about the coils..

 

IMHO, the MSD 6A is outdated technology. It was designed for the late 70's - early 80's HEI ignitions without computer controls. I opted to go with the Accel 300+ digital ignition.

Since we're listing components on our cars, here's what I'm running:

MSD Coil (Accel coil was built a little cheap and came loose in it's frame. It still worked fine, but I wasn't impressed with the build quality)
MSD Distributor
MSD Cap and Rotor (Again, I used to use Accel until I noticed their rotors like to rub on the cap and leave palstic shavings in the distributor. No such problem with MSD)
Accel Extreme 9000 plug wires (these have actually been really good)
Accel 300+ Ignition (No complaints)
Bosch Platinum +2 plugs (Say what you want about the platinum plugs, they are still the ONLY plugs I've used that I can actually feel a difference in throttle response)

That's it. Any other components I go strictly with AC Delco. They've always beaten any auto parts store brand.

 

Brett, I have run several different brands of platinum plugs on both of my OBDI cars. Both have very hot coils in them and the plugs will burn up withing 2-3 weeks and then the car will stumble at idle. I have never had that problem on either car running Autolite standard plugs,. I have even use the Autolite platinum AND the Autolite Double Platinum plugs and the doubles craped out within a week on the Camaro. I have also tried the Bosch platinum 4's on both with the same problems. Autolites will run as good after a year as they do when I first put them in. Its just my personal experiences.

 

I agree. Will you school these folks. That's why they can't keep up with me in the 1/4mi I've been running these plugs for the past 3 years and never had a problem. I have the MSD 6a and a Blaster 3 coil (not the replacement style).

 

RTFC i want to do a full tunup on my car, and i am replacing all my ignition components. do you have part numbers on any of that stuff, the only thing i could find on summit were the wires (almost 100$) and a HYP-4050 hypertech coil/cap/rotor set. do i not want to go with a "in rotor" style coil? thanks

 

Don,
I think you answerd your own question with Allen's car.

 

Not really.....it got choppy with the MSD on and off changing the fuel up and down. 2-3 Hp change w & w/o the MSD does not show a real performance gain (all the runs varied 2-3 hp with changes).

At any rate I wouldn't spend that kind of money for something I know down the road is going to give me trouble. (that's a given)

 

Agreed. That's why I went with a digital box. IMHO, the MSD 6A is too outdated to still be in use. It's old analog technology.

Here's the Crane digital ignition compared to the MSD 6A:

You want the HYP-4055 GM External HEI coil. It will mount in the factory location and use the factory electrical connections. Heat shielding is just a roll heat tape shielding that I have had for years.

Accel cap & rotor: ACC-8133 (This is the screwdown one, not the clamp on style). MSD -8430 is the same just red, and $5 more.

TAY-79245 Taylor 10.4 wores with straight boots (Universal V6 kit, Red in color)

SUM-350109 These are Summit's firesleeves. I have Taylor Firesleeves but are identical to these. Summit is not showing the Taylors.

thanks. also nice to see you on the boards again. didn't you get banned?

 

My msd box killed my mother, and had its way with my father!

 

That dam MSD box it did that to me to
