How many people feel and have proof that a high output coil kills the opti faster? I am about to by a Crane Cams PS91 Fireball Coil and want to know how bad this will be for my opti...

majority of the time its not the high voltage part that fails, it is the low voltage part that sucks *****

 

I dont think the coil will have any ill effects on the opti. If you are that concerned just get a stock replacement coil form Dal or Jason. I debated getting a "high voltage" coil, but went with the stocker. All coils are considered "high voltage". The OEM stuff is adequate and works great, so unless your coils is bad I would not worry about "upgrading". Put the $ toward something else, just my 2 cents.

 

Well, this is gonna sound rude no matter what, so here goes.
I was looking for educated answers. The reason that the low voltage side fails is due to the high voltage causing oxidation.

And in regards to the stock oem replacement coil. My car is far from stock. And my stock coil (fairly new) is having a hard time keeping up.

Thanks guys

 

The high output coils are a total waist of money. My delco puts out 25,000 more volts than the MSD did. Further more with the boosted aplication in my case, it would not even rev past 5k. Went to a stock unit and all problems where solved. There are several people with over 600rwhp using the stock units. IMO delco is much better than most performance parts anyways, if they work in your application.


Yes I did 2 optis in 10k with my MSD coil, and no other ignition components on a stock motor.



If you buy that coil dont expect any PERFORMANCE GAIN.

 

The coil is having a hard time keeping up, what do ypu mean by that. Are you sure its the coil? I say sure go for it and get the crane coil, what the hell. Why would the crane be able to keep up?

 

Why don't you do a few searches and read up a bit before you start making accusations at the people that are answering your questions. This topic has been beat to death.
As for you stock coil having problems keeping up? Could you care to explain that, cause that statement means no sense.
My MSD coil has 40,000 miles and hasn't given me a single problem, I kept my stocker just in case the Might Suddenly Die decides to take a crap on me. It it is still going strong, never had any power-adder blow my spark out.

 

Dave, basically what you have is an opinion poll. There is not enough hard data out there to prove anything. It would take a serious research project to come up with any tangible results, IMO.

That said, I have been running an MSD coil and MSD 6A. I looked at my opti after about 25k miles (from new) and it did not seem to have any unusual wear on the rotor or terminals. All distributors of this type (which includes the regular SBC one) will have some cap and rotor wear. I did not pry into the optical section.
