Msd or Accel Opti?
I've read negatives about the dynaspark years ago, on how really it was a just a glorified stock unit with a billet body. But that was years ago. Who's sqr ??? Maybe I should get dwayne to respond as he usually can convey quite a nice message, but I'll try.
Many MANY people have taken stock optis over 6000rpm just fine. Many people have issues with optis becaues they never look at the opti harness for damage, or they don't replace the vent harness etc. I would have to say a stock opti with a msd rotor and cap would be the best of both worlds.
If you want you can tell sqr I know of an Impala (not that being a b-car or f-car makes a diff) making well over 600hp running a stock opti and it runs 9.6s. Even uses a 4l60e trans..

Well i know my opti issues started with the higher redline. I have looked over the wire and don't see any potential breaks.
I am going msd. Now just need to fix 02 sensor. No voltage on purple wire with key on. Referred to them by

what the heck? Why aren't our posts showing up?
LOL the forum must have been laggin, it didnt show page two. Usually the opti harness can have issues at the pins of the connector.
Im not trying to say the opti is a flawless unit, but people blow it's problems out of proportion.

Ok so no one responded, My MSD opti came with the O-ring, I installed it with the O-ring, does that mean I will have problems? should I take it off and get the rubber molded gasket?
I dont feel like blowing up a brand new part.

Ive heard people who do the stock opti and delteq setup have been carefree about that **** ever failing again...I'll ask my bud tom tonight about it and post back but I'm pretty damn sure he was happy about it and laughed when I said about putting an MSD / Accel in there

Do you know if this a Tech dept email or just a general one?

I have a Dyna Spark on my Impala, Never had any problems with it. It was on the car when I bought it. I have used and installed SEVERAL GM opti sparks with no problems. However I highly recommend balancing the rotor. I made a small balancing fixture just for this. I used JB weld on the rotor side then sanded off some of the counterweight side to make it balance out perfectly. A small drop of loctite on the rotor screws to make sure they don't come out will also go a long ways. I have tested the GM opti in this manner up to 7000+ RPM with no problems!!! I vote for the messaged GM opti! 
well I am going to go msd since the optical unit is better and I am sure more presise (sp?). Anyway contacted a seller on ebay and asked about the oring thing and he said his stock showed to have the oring so i would ask your supplier before buying...
i have the MSD unit.... i got mine installed before Summit even started putting them in stock... i love it.. being it was one of the first ones... it had some kinks... but i had aboslutely no issues at all... but i took it off the other day and noticed it was rubbing just alittle... this was a known issue that MSD has already taken care of... so mine is being covered by warranty and getting a new one for the new project... i had about 12K miles on mine with no issues...
Ok well I talked to MSD and they said that the only problem with the O-ring is people were not installing them correctly, the o-ring goes on the little flange, not on the outside of the plastic part that surrounds the rotor. if the o-ring is installed on that plastic part it pushes in the plastic part causing a clearance problem with the rotor.
That is the reason for them making a gasket, its really hard to get the oring to sit on that machined lip, I know I didnt so I am going to have to dig into the car this weekend and fix my mistake and product of impatience

What type of sensor does the MSD Opti have? Does it look the same as the GM? I know the GM opti's have a Mitsubishi sensor. What makes it better than the GM? and what about the reluctor wheel? I know the GM on is rather delicate. Is the MSD one thicker or bigger diameter?? Just curious.

yea Harvick the instructions are really really vague, and I told the tech guy that I spoke to and I asked him to be really really specific so we talked for a bit and I found that little bit on the oring lip

I had a problem with the msd unit also the first on i had i put on and the rotor rub and it burnt out. they second one i got i have a certified mechanic do it and the same thing happened and i sent that one in to figure out what was going on and they told me that the o ring was installed incorrectly. Well they still warranty it i have the new gasket in and seem like no problems but i haven't hardly drove it now. How many people have had the same problem as me??
