going to run my buddys c5 vette later on this week... what is the biggest shot i can do with my stock plugs? also for future refrence how safe is the 200 pills they send with the kit?
N.O.S. question: what is a safe shot on stock plugs
- Thread starter BHARRIS

platinum and N2O don't play well together. If you were desperate, you could put a .040" pill to it once and probably be ok. If it was me, I'd spend a few bucks and put some NGK 6510s in it. With those plugs, some race fuel and a dedicated nitrous tune, you could probably run your "200 shot" (.07x" pill I'm guessing). Who's kit is it??
FYI: The older "TR" plugs are too short for the Coyote heads. The plug won't reach far enough in to the chamber. You have to use the longer "6510" plug.
ALLKHEINZ used to run 150, 175, & 200 shot on his 12'! I would ask him! Plus I am pretty sure he ran stock plugs.
thanks it is a nx plate kit, none of the stores in my aera have the right size plugs for sell that are 1 to 2 heat ranges colder... ive got some ordered and they will be here on the 7th, the race is going down on 1st so kinda sol there... i have the sct advantage 3 software so i can make a tune for it. you think i could do a 100-125
i understand you can go up to 125 on a stock tune and stock plugs(wet kit).
then you want to take out 2 degrees of timing for each 50hp addition.

my best n/a run with my 03 z06 was 12.20 with a mid cam,bigger injectors and new nittos 555s at the time.... and that was power shifting trying to rip the shifter outta floor cuz i wanted to break into the 11s for i have a money bet goin on at the time lol
so whats the vettes mods? unless hes spraying too i wouldnt worry to much

are you running a b.a.p.? its a good peace of mind once you go bigger than a 125 shot
vette has heds,cam, intake, long tubes, and he has a bottle on it said hes running a 75 shot.... prolly going to be a good race
no but ive got one off of a 99 cobra i had, might have to hook her up
my car has full cobra jet suspension, sway bar delete, 4.30 gear, off road h, intake, tune, and nitrous... we are both on et streets mine are 28'' radials his are 26'' bias ply...
If I remember right, Platinum acts as a catalyst with nitrous and bad stuff can happen. Somebody explained the chemistry to me once, but I never messed with those plugs, so it went in one ear and out the other. Start with a slightly richer a/f and pull about 3* of timing out with about a .050" pill and go from there. NX's out-of-the-box tuneups tend to run a bit rich, but I don't know an EFI jet spread off-hand to give you. You'll have to do some logging and sneak up on it. Please keep us posted!!
I sprayed 100 shot on the stock plugs, but I did have a nitrous specific tune.
150 shot with stock plugs gapped to .031 and you should be fine.
What is considered safe and what you can get away with are 2 different things , typically a 50 shot is your limit on the stock heat range plugs , can you do more ?? Yes but any reputable tuner will tell you not to. I ran a 50 dry shot (35 jet) with stock plugs no issues and when I pulled the plugs to go one step colder they were still in perfect condition
Don't trust that "75 Shot"... Coming from the Corvette world, take it from me....Prob more like a 125-150 on your basic bolt-on C5.
Not saying he isn't running a 75, but its not the norm with those cars.
I thought coyote motor used iridium plugs not platinum ??
