Anyone have info on the new Opti from MSD?

RacerX70CC

Got one in and sold it immediately (the late style)... I'm waiting for some more to arrive, tho. Nice piece, very well constructed.

Summit has them on there web site

Both early and late versions?

Corvette Central in their latest catalog has both styles. $519.OO each

I'll be grabbing one soon to go with my new engine and I'll post a review at that time.

Summit lists the early style for $499.00.

I guess if it lasts several years, it's worth it...

RacerX70CC

I got that beat.... just a matter of when they hit the door.

edsalinas

Oh yeah?

So tell us,
how much $$ can you sell me an early style for? I'll be tearing the front of the LT1 apart in the next few days, so I'll be looking to pick one up soon... PM me with the info bro.

How does the MSD compare to the dynaspark??

What is the actual improvement in construction. Is it going to prevent the problems that the opti is currently having. Is it sealed better, will it prevent the caps from going bad. When I disassembled my cap I saw no problems with it that I could see visually. Rotor looked OK to. The other side except for a little rust on the housing, wheels looked OK. Don't know what was wrong with it but the new one fixed the runability problem. I beleive it was 11 years old.

The question is, is it going to be a better product 10 years down the road......or 5. Would just like to know why it better?

My (limited) understanding is the bearings are the main problem, in addition to the moisture getting into the early styles. MSD claims they solved both issues...

DYNASPARK

1.) The bearings used in the stock opti are rated for 13k rpm. It is an NTN bearing, which IMO are the best sealed bearing you can buy. The problem lies deeper than a "bad" bearing.

2.) The MSD unit arrives with the cap uninstalled, making sure you have the proper seal isnt just as easy as bolting the cap down onto the housing, expect problems.

In dealing with these units for 10 hours a day 7 days a week I have learned quite a bit about them. Ive said it before and ill say it again...

So does that mean a stock 95 opti would be better than the msd? What specific problems did you have with the MSD. How did you solve the cap issue? I have plans for a cam swap in the future and I figured that with 80k miles I should look at the opti also. I was panning on using the MSD opti.

Thanks

Does the Dynaspark use the same stock bearing?
If not, what is different about your bearing?

Then why dont you share your secrets with the general public. It really is sad that a POS unit is modified to work better, not always longer, and the general public still has to deal with crap. I am not saying Dynaspark/MSD/ACCELL or even GM are good/bad or indefferent, but Dammit, tell us what do to if we do by a OEM, which has a great warranty (which is free, and you can give it back every year no questions asked and get a new one, even though the labor sux), its still free. What can we do to make ours better when we put it on a modified engine, as untouched engines seem to not be as much of a problem due to fitment.
So tell us, what is it that we can do to make ours survive?

DYNASPARK

I feel like it would only harm my business to share that kind of information. My suggestion to those who wish to modify their stock opti for reliability... take it apart and you will see some of the problems right away, other problems come with testing and expensive r&d. We have addressed all the problems and fixed them, if you want an optispark that works and will last then you know where to get it.

DYNASPARK

Do I even have to answer that? (respectfully)

DYNASPARK

We do use the stock bearing, we just use a 360 degree retention ring with a press fit housing rather than the sloppy oem two bolt stainless ring that only supports %40 retention. We've never had a bearing fail.

DYNASPARK

I'll answer your questions in the order they were received.

No, I have not tested an MSD, do not read too much in to what I say because you will start to wonder and then get confused, take it for what it is. My intentions are to help customers better understand these distributors and what they are buying so that they can make a better decision. I am trying not to post what MSD has done wrong with their distributor for two reasons, 1.) so they dont sue me and 2.) so they dont change it and the Dynaspark is the better choice.

I will not comment on my testing of the MSD opti.

How did I solve the cap issue? There are several issues, and how they are solved is proprietary information that I have chosen not to disclose in order to protect my business.
