I've been trying to resist the temptation. I can't go with much of a shot however. I'm using a glassy-smooth bore finish with a tight end-gap and a wide LSA roller. And I'm already using the coldest plug I can get without getting into the ice-cold NASCAR plugs which are Gerschtunken for street use. IOW it wasn't built for Nitrous. I think a 100 shot would be a semi-safe max unless I tear into again (and I'm too lazy) But if I pull the trigger, I can sure give you a shout. Thanks!
NOBODY on this site is allowed to call Nitrous: "NOS" as it is right off the set of Fast & Furious and is fucked up. :chain:
I'm using the coldest Iridium that NGK makes with a 1.04" reach (for the Strikers). LFR7A-IX The other option: R7437-8 are $50.00 each and are designed for extended high r.p.m. use and are not a street plug. The Iridiums can be tricky to gap with that tiny pin of a firing-tip but so far, so good.
Çhampion's numbering system would have a colder plug than the RC 12 ECC as an RC 11 ECC (if they even exist). NGK's numbering system is the reverse. A colder plug uses a higher reference number. I'd check with Champion to see what they recommend. If you want to switch brands, numbering systems tell only part of the story. A 12 from NGK might not actually be one range colder than an 11 from Champion. Clear as mud??
Use the white truck to tow the black truck to the track and go and have some fun. Bolt on your Drag Radials, drop the pressure to 7 psi. Hold the revs right at 6000, dump the clutch and hang on. You should have a wicked 60 foot and if it is still around at that point, keep shifting and wait for another 9 seconds or so until you roar through the traps with a big smile on your face. Have fun.
