11.7 to 1 408, PRC stage 3 heads, pump gas (93) in the tank with stand alone cell (probably 110 octane) for the spray. Gonna start on motor, then spray 100 to start. Eventually end up at 200 max. Shift at 6500, A3, etc.

I'm thinking TR6 at about .030, but been into blower cars running NGK8's at .027. Different setups, getting back into the nitrous stuff for now.

 

from what i understand, tr6 is a good tried and true plug, i personally run ngk BR7EF, wich is one stage colder then the tr6. but as far as gap, youll get alot of different answers. i started with .035 and still using .035. Probably just cuz i dont know anybetter. lol. im sure someone will come along and help more.

 

motor ~ 7 or 8. nitrous 9 - 10 don't mess with the gaps on the 9 or 10 just check them to make sure there even.

 

That seems really cold on motor, no? I'd think I could run TR6's at .035 on nuts, but I'm trying to learn here.

I plan to street drive this too, not daily, but won't those foul easily?

 

i was just about to ask this stuff haha!!

 

I ran TR8's in the Z/28, might have been a little bit of overkill but the car drove fine NA and never fouled the plugs. I pulled them twice but they were nice. I do think that some folks push TR6's a little too much, they are only like one heat range colder than stock.

 

We also recommend a non-protruded plug against the protruded TR6. Dont get me wrong, the TR6 is a good plug but if your going over 100 shot I would get the BR7EF(non-protruded) just to be safe.

 

No, i would also run a heat range 7 plug on the motor. TR6 might be ok, but its not like you would sacrifice any power from using the 7. nonprojected tip heat range 8 for the 100 and maybe a 10 for the 200. Like Shiz said, keep the gap the same out of the box. pretty sure its 35.

 

mine were gapped at a .030 out of the box. just fyi

 

I ran TR6s today on the dyno with a 125 shot and everything seemed to work out fine 12.0-12.4 AFr and read the plugs and they look good!

 

I'd say TR7 or 8 gapped to around .030. Thats a decent amount of compression and a good shot. I think you're past the point of TR6's.
