as the title says. I've got NGK TR55's but now im running heads/cam/stall all the goodies yak yak yak. no nitrous though. would the 55 gap be fine, or should it be closed some? Say 50 or maybe 45

I searched on this and people are gapping them anywhere from 45 to 55. I split the difference and went 50.

know the pros/cons of gonig with a lower gap?

generally speaking more gap=more power. Gap needs to tighten up when cylinder pressures get really high such as in blown and nitrous apps.

so what would you gap them at if you were in my position?

55. Larger gap = bigger spark = more complete burn.

i always heard that the more mods you've done to make the gap sequentially smaller. i "believe" it was something like an extra .005 less for every extra 50 rwhp? so if you're making 400 rwhp you should lower the gap from .055 to .045?

I would imagine with these wires you could run a larger gap... correct?

You can also run TR6s gapped between .035-.038 since you are heads/cam

Thats what I run, TR6 .036 gap. But since he has no intention of ever spraying I would stick with the 55's gapped at .040-.045

hey, brad, i got the TR6 also, and just gapped them at .038. should i take it to .036 gap? i am just finishing the H/C and stuff installed now.

Mine are somewhere between .036-.038 I can't remember exactly. I've had TR6s in mine since Feb. but haven't sprayed it yet and she's been running great. I've only got two and a half more months before she's sprayed for the first time
