I dont have a wideband right now, so I would appreciate any feedback from those of you that can read sparkplugs. About 3k on them, and no smoke under WOT
bre8es-460+whp car

PIXS ARE ALL ONE PLUG I PULLED, THE REST ARE SIMILIAR

 

What kind of fuel are you using? Is it just 93 pump gas?

 

yes just 93 pump

 

Could be reading it wrong, but a 460whp car was built and no wideband?

 

yes, one is getting installed this weekend, when the car was tuned it was on a dyno with a sniffer

 

looks normal... good color.

 

Looks good, no blistering, no white discoloration, etc

 

thanks guys just wanted to make sure


Does it look like it might be a bit on the rich side?

 

Over all plug looks pretty good. It does look like it may have detonated a bit during the tuning time at one point. The shiney sparkles on the strap look to me like little bits of aluminum, which comes from the top of the piston when detonation occurs. Its nothing to be concerned about if the car is running fine, though.

Timing looks good and conservative. I say this because as you increase boost and timing you will see heat move up the threads. You have heat mark on only one thread, which is good. With race gas (VP Import) or E-85 I've had heat 3-4 threads up, which is fine with those two fuels.

Over all, I think it looks fine.

 

Looks good, might want to back the timing down a little. The color shift should be in the middle of the arch.
