Opti-spark with heavily modded camaro?
Opti-spark with heavily modded camaro? I have a 383 lt4 with a procharger and I'm running about 12lbs of boost. I have a MSD ignition and an accel super coil. I went to dyno my car and I had a lot of ignition problems. I had a lot of misfires at high rpms. Someone told me that an opti wont work with msd and I don't know if that's true. Anyone have a supercharged lt1 with what I have and if so is everything working fine? If not, what do I do as far as the ignition setup?
I had similar problems with my stock lt1 @high rpm's. I converted over to the delteq ignition and it was an instant hp gain. Upon removal of my opti, I cam to find the optical pickup was fine, Turns out the MSD ign practically melted the cyl pins right off of the cap. The opti is fine, It's the cap and rotor that your baking.
Typically when the opti goes bad the car will run like it's on a rev limiter or it will back fire during acceleration.
There are other alternatives, like drilling a hole in the back of your intake for a vertical distributor, or there is a company that has redesigned the opti, having a brain fart and can't remember the name.

Dynaspark http://www.dynotech-eng.com/dynaspark.htm , personally I think they are overpriced, but their billet aluminum base housing coupled with the new MSD opti cap/rotor might be decent.
Bob Bailey's http://www.bailey-eng.com/LTCC.html setup. I like Bailey's system because it allows for tuning the box via dipswitches for nitrous or in your case forced induction. His system coupled with MSD LS1 coils and a good aftermarket computer & tune should give you an Opti trouble-free BEAST! Make sure you get the correct wiring diagram for your year car though because if wired wrong to the coil it will damage the Bailey box.
Delteq http://delteq.com/default.htm ,nice setup as well, I don't care for the 4 big coils mounted on the driver side valve cover, but for a stock engine setup this is a plug and play system with their simple wiring setup. A while back they were working on a setup that would do away with the high/low res pickup sensor setup in the base altogether, not sure if they gave up on that or not, but they do have a billet dist cover they are offering.
This sight has some good searches, many have tried several custom options, just an example of someone using a turbo setup http://web.camaross.com/forums/showt...opti+solutions
Another interesting read I found http://www.corvettefever.com/howto/16758/
I have had a Dynaspark distributor in my race car for two years now and it works very well (7200 rpm shift point on the 2-3 shift). Before that I ran Optis, but they would sometimes miss in third gear on the top end. I have a lot of friends that run modified Optis with an MSD and a crank trigger.

That's exactly what happened. We thought the msd had a 5500 rpm pill in it because the car cut out at 5500 everytime. We checked the msd and no pill was in it. Once we unhooked the msd we got the car to get up to 6700 and that's when we had all the misfires.

Is it a stock opti that you were using?
so it sounds like everyone that had problems got them from using some sort of msd. those of you that had problems, which system were you using? i have a 6A laying around i want to use. after reading Formula WS6's post i think i will defintly go with msd's cap and rotor(thanks for the link BRETTINATOR)
I was going to go with the msd cap and rotor in the beginning of this year when it was going to come out. I decided against it for several reasons. 1 MSD said it would be avalible in late feb. 2 msd delayed distribution because they were having problems during testing. 3. Summit sold a rebranded cap for a couple of bucks cheaper which only offered a 60 day warranty. I wasn't going to spend a 150 every year and a ton of time to keep changing these caps, which I love doing. So that's why I went with the delteq, it eliminated the cap and rotor all together and the need for the msd ign box. It was a 6a.
I ended up paying around 625. I made my own msd wires w/ heat shields for the boots-100.00, purchased the coil/module from e-bay for 145 (new), bare bones kit form delteq for I believe 360. They sell entire kits for 670, but their ign wires aren't any good, they are also 3 ft long per wire. I went with the valve cover mount and brought my wires right over the top of the motor for easy axcess.
So, basically I can keep my gm opti if I ge the msd cap and rotor? Or, I would go with the delteq or the dynaspark. Right?
