Ignition break up
Just wondered if any of you running over 17psi have had ignition break up and what you did to solve it. (I'm sure alot of guys running high boost have) As soon as we hit 6k and about 18psi (we're running a t78) we get break up. Right now we're running 11.5-1 afr's, stock plugs(trailing in both spots) I did a pull with the trailing disconnected just to verify and it made no difference. I've ordered a set of iridium plugs and a different style plug so I can try setting the gap a little tighter. I'd like to eliminate any possibilities before going to msd or some such system. We put down 447whp and 365ftlbs lifting the throttle at 6k. Everythings smooth as silk right to 6k and if you half peddle it on the street it's fine to redline, the ignition problem only occurs at anything above 17psi. Thanks,
Brent

With the AEM duel cap amp you can drive all of your coils .I am useing one to fire four Jacobs C4 coils .The new design amp has been working great for me .I have had several that were bad as I was beta testing for the company .The one I am using has been in there for about two years .

What's your setup? Turbo,boost level,porting,power levels? I've had great success on my fc with the iridiums, lasted the entire season last yr and they're still good. I don't think I've ever had a set of plugs that long and I was running 15psi.

At a recent dyno tuning event with Steve Kan, I discovered that I am getting ignition break up at 10 PSI at high RPM. We borrowed and installed an HKS Twin Power from another car (thanks Phong!) but the break up continued to be present.
Adding parts isn't always the answer. Sometimes you have to troubleshoot and repair the base items. Not sure if I should replace with stock coils or if there is something better.

As we all know the twin power is designed for higher horsepower cars as it gives that extra power that the stock system cannot put out. Essentially it's a bandaid. The true fix is to upgrade entire ignition system, but most of us don't really want to do that.
so in otherwords you have upgraded your CFM (turbo), and fuel consuption and therefore increased your WHP by roughly 225... Yet leave your spark completely stock. At some point you are gonna have to upgrade what BURNS that increased mixture (ignition) as well. I think you've hit that point

That's the thing, I'm going to go through all the other possibilities first before I go installing aftermarket coils etc... Thanks for the input guys.
