Is This Lean?

[AverageA31]

Gday All, got my cefiro up and running with a few mods(car was bought minus motor and box). It seems to go ok by the seat of my pants

but after a short drive I pulled my plugs to check the gap (0.8mm)and this is what they look like.

It is already booked in for a dyno this week but the shop is 1/2 an hour away-is this safe to drive that far?

Mods:

Bosch 044 fuel pump

GTR injectors-clean and tested ok

Z32 AFM

GT2871 turbo

FMIC

3 inch turbo back exhaust

ECU remap-tuner has checked and confirmed against his other files that its correct for my mods.

thanks for any help

They look fine. Don't boost to the shop if you are worried.

are those copper plugs?

If you looked at the first picture you will see they are bcpr6es plugs. I also may suggest you run 7 heat range plugs.

[AverageA31]

Yeah these are copper plugs, I didnt know whether to go 6 or 7 heat series as there are tons of guys doing both,

my tuner said 6 so I did that. What would the difference be with a 7 plug?

Where can you get BCPR7ES? I can only seem to find 6's and no one has the 7's in their system.

it's just a safe measure, 7 will stay cooler when the engine is running above standard measures. Lower the risk of pre ignition. Repco should have them, super shit won't.

I've bought many sets of 7's and each time either Bursons or Repco have had them in stock

Its very hard to tell lean and rich from plugs when you are running fuel with no lead in it.

What I can tell you is that your cylinder temps are too cold for that plug or your plug is too cold for your cylinder temps.

The white porcelain of the plug should be clean and white much further up the plug than where it is.

You could run a 5 in your engine, or lean it out to up your cylinder temps.

His op said, new plugs out after a short drive. I really doubt that short drive is substantial time to darken the porcelain...

umm I think we are talking about different bits.

Im talking about the part that is in the combustion chamber. Can be made black from cold start and only a few min of running.
