HP...Thanks for the data...what plugs are you using???
Plug gap info
Recently I've experimented with plug gap, just to see what
voltage limits my Viper was capable of. My conclusion is that closer to
.030 the better - anything over .035 is questionable - .040 causes my
car to 'flutter' at WOT. This was w/ and w/o nitrous.

Champion RC9MC4
Gerald, I picked that plug because that's what was available in the
heat range - ground strap - I was looking for.
I had the parts store show me a plug from NGK , autolite, and Champion
all crossreferenced - and the only one that they had enough of was the
Champion. - but I'm pleased with my selection -
Right now I'm running .030 gap - and it seems to be right

HP...I currently am running the NGK ZFR6F-11...But I have a brand new set of Autolite 3923 that I thought about trying on...
0.030 gap duly noted...

Gerald I did a search on VCA plugs/nitrous and I think I picked the NGK
plug you have - anyway the 3 brand plugs I looked at -including my NGK reference-
looked exactly the same, as far as visual aspects -
So I would doubt there would be any noticeable difference - if you have another
set use them - it just happened that the Champions were the only brand that
I could get a full set. I'm assuming the NGK you have is one recommended off
the VCA board. It appears to be a few clicks colder - shorter electrode.
Odd thing is, the Champions I got - were never listed by anyone in my search -
nor were they listed on the Champion website.

For anyone else tuning in - this is how Gerald and I communicate.
If your car is stock and doing well - keep your stock recommended plugs
with your stock plug gap.

What about Champion RC12LYC plugs?
Those are lawnmower plugs. :nod: And no I am not bullshitting you.viper spray said:What about Champion RC12LYC plugs?
So they will work well in an "old tech" engine as in the Viper. Not for use with N2O though....
So should a guy like me with a 95 and 2K miles switch to a Champion RC9MC4? Don't tease me about the miles...I just got it last year.
The stock Champion RC12LYC plugs are fine, HP and I are refering to nitrous applications, where colder plugs are required...
2K on a 95??? holy shit!

So is .030 recommended on a stock engine(no NOS)? I always thought that as long as the spark was strong, the wider the better? I have mine at .040 and have not experieced the flutter.
When you throw the N20 to the cylinders, a bigger gapped plug could actually get the spark "blown out"...therefore a smaller gap is recommended...96 R/T 10 said:So is .030 recommended on a stock engine(no NOS)?

voltage is just maxed out at that gap. I think for the stock plug the upper gap is .035 There was a thread the other day
on S/Ced cars - and someone mentioned .028 as a reference. Denser charges
from the higher cylinder pressure of nitrous and S/C limit the amount of gap
further.
