Well maybe I'm the lucky one who's had 3 sets back to back with issues. Who knows.... I'm sticking with the NGKs after all the issues I've had with the Brisk ones.

I'll get some plugs ordered and see what's happening. It's gotten worse so I just quit driving it.

Yup.. You defiantly have a plug that shit itself. Get some new ones in and it will be fine!

So when the new plugs arrive should I gap to .028 like Whipple suggest or open it up to .032?

I would consult with your tuner... But I gapped mine at .030"

Yeah, ended up having cracked porcelain on my number 8 spark plug. Put fresh plugs all the way around and the cars been running great, no hiccups whatsoever, and makes great power. Made 687 horsepower a few weeks ago

Hey Mike
Any passes lately with the lovely cool weather we have had lately ?
...kicking myself not having a car to run .
When you come pick up the driveshaft/trans I would love a drive in your car(I will let you drive mine !)
I am really starting to think I chose the wrong supercharger .
May be I can sell this KB and jump on the whipple bandwagon (or throw a whipple on the GT 350.:cheers:)

Was the porcelain cracked above the hex nut externally or broken inside the chamber near the electrode of the plug ?

Mine was broke near the electrode. Brisk plugs.

Not saying that this is the case or not BUT if the porcelain breaks at the electrode DETONATION is usually the cause regardless of the spark plug brand being used. I have used BRISK plugs in the past with 800 RWHP on gas and E85 and never had any problems with the porcelain breaking, if it cracks on the coil side of the plug that is an installation error.

No passes since I installed the blower. Still waiting to do at least half shafts and slicks before I get it out on the track again. So hopefully here in a month or two.

And I don't think you can really to wrong with KB or Whipple, they're both great kits.
