Yellow Plugs after nitrous run?
I have a delema with the nitrous system on a vehicle the setup is as follows:
sbc 350 .030 over
forged manley blower pistons 8:1 comp.
race prepped rods, crank and block
bowl blended heads
TBI setup
1 annular discharge nozzle
with .065N .053F jets
run 10lbs. fuel and 9-950lbs. nitrous psi.
After a run the plugs have a yellowish tint to them, I don't see any other
signs on the plugs as being to rich, or lean cond.
the plugs do show a rich idle but thats from the cam I'm using
the computer doesn't like it at Idle.
Anybody ever run into this with having yellow tint on porcelain after a run?
and it only does it on nitrous?
Thanks,

Yeah, that stuff is to keep idiots from huffing it.
Didn't phase my neighbor though, came by when I was taking my bottle our for a refill, he asked is it empy? I said yeah, he grabs it takes 2 big hits and said no it's not :shock: I just shook my head.
