OK lets get the facts straight.Steve chewed up 2 Dynasparks and they told him it was his fault for not following the instructions on the measurements that need to be done before install if I remember it right.He maintained that they were defective.I also recall that Steve did have a problem with his car and got it fixed.So they had a heated exchange and it appeared to me that Dynaspark was correct.Is this all correct Steve?As in all disputes someone was mostly right and someone was mostly wrong.I agree that Dynaspark (like RD Racing) is a topic for debate and the way the vendors handle controversy can affect their sales.Dave does a great job with his, these guys need a little better attitude in public forums . Just my .02

The Corvette ran fine before and after we changed the coil, wires, etc. I put it on the Dyno to see how much horse power the car was making. That is when we found out the spark was breaking up in the higher RPM range. With the new cam, heads, etc I wanted to ensure it was worth the money and see what kind of gains it produced. I tried to correct the problem before replacing the OEM optispark." CharlieLT4

so, I'm understanding that the stock Optispark began breaking up at about 5200 rpm. Is that normal for an Opti, that it can't go beyond or up to 5200 rpm? I thought an LT1's redline was about 5700-5800 rpm, which means this was, in fact, a defective Opti.

From what I've read toward the end of this thread, is it possible a well-functioning Opti could handle the LT4 conversion---that's a question because I have no idea what the conversion's upper redline limitation is? Does the conversion have more than the stock redline for an LT4 which I think is around 6300 rpm?

 

Correct. The Dynaspark broke because of a Reluctor ring vibrating the timing chain, gears etc. I was given the third degree, and until the president, Phil, got involved I was being treated unlike a customer should be. If you look up "Dynaspark" in Search, click archives (C4 section, it is about the third page. The post is really long. The hardest part was the way our emails were handled. I wanted my money back cause I was pissed, as I didnt know my motor broke the Dynaspark, and figured it was the Dynaspark. The first Dynaspark wasnt broke, it only had carbon tracking in cylinder # 6 plug hole. Anyways, It was an ugly post. Nevertheless, Phil fixed it, and I thanked him for that, and apologized on the forum, and praised the company. Then today, hammered again, no matter how slight. Phil needs to rethink there customer service, as a great product, and other products they make could suffer sales if this guy pisses the wrong guy off , again.

This is getting really dragged out, however to answer the question, no I did not click "archives". All I initially did was hit "search", and type in DynaSpark. As I previously mentioned, all I got was a few general references.

Not to prolong what appears to be a sensitive subject, I'm certainly NOT impressed with Dyno Tech's "public relations" department. I'm a "car guy", been spendin' money on my cars, tryin' to get them to run a little better for about 35 years now. Spent a TON of money over the course of time, some of it on good stuff, some of it junk. I was just attempting to get a feel for a product, to determine if it might help my car, before I spent $600 on it.

Bottom line, if this is how Dyno Tech treats potential customers, I'll keep my $600 in my pocket. Worst case, if the car acts up, I'll try an MSD cap and rotor for $150. If that doesn't fix it, I'll purchase a brand new Opti.... and put the MSD cap and rotor on it!

Thanks for the input, guys, and I apologize if I caused anybody any heartburn. I'm back to the C-5 and F-bod sections.....

 

Yes, you are correct. My stock OPTI was failing above 5,200 rpm. No,that is not normal. A stock opti should be able to handle the factory redline with no problems. My new OEM replacement optispark was bad. I didn't want to replace it again and went with the Dynaspark once I found out what the problem was.

Yes, the Dynaspark has a higher redline than stock. I belive the Dynaspark can go to 6,800. The conversion has the same redline as the stock LT4, 6,300.

You can e-mail me and I will provide you with my phone number if you have any additional questions, or post them on this thread and I'm sure the usaul "forum experts" will continue to provide you with answers...

 

Any chance of you guys putting the MSD cap and rotor on the ones in the group purchase? :-) Come on, make everyone jealous on the purchase...... make them become customers. OK, I'm baiting the deal because I want one, but I didn't know the dynaspark used the factory cap and rotor (with rivet I understand now) on their new distributor. Hey, thinking of this... would it be possible to get some credit for the factory cap and rotor and pay a difference on this group purchase? I'm trying to the right thing, one time. Not having to repeat the process next year. But there should be a new Z06 parked next to the LT4 next year anyway. I love the C4 body style and it told me it wants a brother. :-) Can Dynotech recommend a good performance plug wire to use with their distributor? I am interested in a good performance wire, not worried about noise on the radio really. Thanks.
